"Stand up straight and stride." Under the guidance of medical staff, Xiao Chen, a running friend, is conducting exercise treadmill experiments in Beijing Hejia Hospital. In the Beijing Half Marathon in April this year, Xiao Chen had a cardiac arrest. Fortunately, he was discovered by the volunteers of Hejia AED, and was successfully rescued through cardiopulmonary resuscitation and AED (External Automatic Defibrillation Transporter) electric defibrillation. After months of recovery, doctors need to re-evaluate his heart function.

　　The start of the 2019 Beijing Marathon is just around the corner, and even senior runners may "stumble" and face the great risk of sudden cardiac death.

　　Cardiology experts remind that six types of patients, such as those who have a history of myocardial infarction, those who have been diagnosed with heart diseases and have undergone surgery, and those who have a history of unexplained syncope, are generally not suitable for marathon. If you want your heart to be safe in high-intensity events, you need scientific cognition and pre-competition heart evaluation.

　　Senior runner’s cardiac arrest AED successfully rescued

　　"I was more excited when I finally sprinted. I shouted and rushed over. After a few steps, my feet were soft and I suddenly lost consciousness." Xiao Chen, a runner who suffered an accident in this year’s semi-Marseille in Beijing, said that he has ten years of long-distance running experience and participated in eight or nine marathons, which is a senior runner. I didn’t expect that this time he became the object of "first aid".

　　At that time, it was Yuan Tong, an emergency nurse in Beijing Hejia Hospital, one of the medical security units of Beijing Half Horse Race, who was present to defibrillate Chen Jinxing AED. She said that the timely discovery of the support staff and the skilled use of AED pulled Xiao Chen back from the death line, otherwise once the cardiac arrest was not treated for 4 to 6 minutes, the brain would be irreversibly damaged, and even if the heartbeat was restored, it might become a vegetative state.

　　Wang Dezhao, chief physician of the Department of Cardiology, Beijing Hejia Hospital, said that cardiovascular system accidents that often lead to cardiac arrest and sudden death in marathons are usually sudden acute myocardial infarction or malignant arrhythmia. Although the probability of occurrence is low, once it appears, it is the most dangerous. It is the most effective way to rescue patients with cardiac arrest and sudden death by using artificial chest compressions and AED defibrillation in the early stage. Beijing United Family Hospital is the official and exclusive designated medical service provider for Beijing Marathon. All AED volunteers have passed the cardiopulmonary resuscitation training organized by the American Heart Association (AHA) and obtained the certificates of Basic Life Support (BLS) and Advanced Life Support (ACLS), so they have the ability to find and rescue runners with cardiac arrest in the first time.

　　Six groups of people should have a heart evaluation before the game.

　　How to run a horse safely? Wang Dezhao said that runners must first have a clear understanding of their physical condition, and the following groups of people are not suitable for participating in such high-risk events.

　　First, patients who had a history of myocardial infarction in the past, especially 6 months after myocardial infarction; Followed by patients who have been diagnosed with angina pectoris, or have undergone coronary stenting, coronary artery bypass grafting and installed pacemakers; Third, it is a patient who has a history of unexplained syncope or has done electrical cardioversion; The fourth is patients with severe arrhythmia or taking antiarrhythmic drugs; In addition, patients with a history of congenital heart disease, cardiomyopathy or cardiovascular malformation, and patients with special ECG manifestations, such as Brugada syndrome, long QT syndrome and preexcitation syndrome (all three groups have special ECG manifestations), are not suitable for high-risk events similar to marathon.

　　In addition to people who are not suitable for horse racing, there are six groups of people who can participate in the marathon, but they need to be evaluated before the race. The first category is people with risk factors of coronary heart disease, including smoking, hypertension, diabetes, hyperlipidemia, family history of premature coronary heart disease (male < 55 years old, female < 65 years old), heavy drinking, sedentary, obesity, staying up late and working under great pressure; The second category is people with family history of sudden cardiac death; The third category is people who have had severe diarrhea or used diuretics recently, and it is very likely that there are abnormal levels of potassium, magnesium and calcium ions; The fourth category is people who have arrhythmia without drug treatment, including sinus arrhythmia, various premature beats, sinus bradycardia, etc. The fifth category is people who have had discomfort in the area below the jaw and above the umbilicus related to activities, or have palpitations and shortness of breath; The sixth category is people who are anxious, hypochondriac and have had a history of panic attacks. Most of these people do not have the typical symptoms of organic heart disease, but they belong to high-risk groups. If there is no heart assessment, there may be unexpected situations in extreme sports such as marathon.

　　Three types of heart assessment help runners stay away from accidents

　　Wang Dezhao introduced that marathon is an extreme sport with certain potential risks. However, as long as the heart function is scientifically evaluated before the game and the physical condition is known in advance, accidents such as cardiac arrest can be avoided to the maximum extent.

　　"If the heart is compared to a house, then it has three systems, including waterway system, circuit system and structural system." According to Wang Dezhao, heart evaluation is also divided into three categories according to three systems: the first category is the evaluation of the "waterway system" of the heart, and the "waterway system" refers to the blood vessels of the heart itself &mdash; &mdash; Coronary artery. If the runner has chest tightness, shortness of breath, chest pain, pressure, burning pain, pain in the left upper limb or left shoulder and back, which suggests that angina pectoris is possible, it should be evaluated by exercise treadmill test to observe whether the runner will have myocardial ischemia when he reaches the limit heart rate, which is also a simple and effective means to screen coronary heart disease. If the exercise treadmill test is abnormal, further coronary CTA or coronary angiography is needed.

　　The second kind of evaluation depends on the "circuit system" of the heart, that is, the evaluation of cardiac electrical activity. If the runner has palpitation, irregular heartbeat, too slow or too fast heartbeat, it suggests that the cardiac electrical activity is abnormal, and it is necessary to do ECG monitoring for 24 hours, 7 days, 1 month or even longer. By monitoring the ECG changes at the onset of symptoms, the disease can be diagnosed and whether it is suitable for the competition can be evaluated.

　　The third category is the evaluation of heart structure. If the runner has heart murmur, myocarditis, cardiomyopathy, congenital heart disease, etc., it is necessary to evaluate the morphological structure of the heart by heart color Doppler ultrasound. If you have serious structural heart disease, especially hypertrophic obstructive cardiomyopathy or aortic stenosis, you are not suitable for marathon.

　　How to predict and save yourself when you suddenly feel unwell in the game? Wang Dezhao said that first of all, runners should stop exercising, rest in a comfortable and relaxed posture, and seek help from medical staff; If the heartbeat suddenly accelerates, fast and even, it may be supraventricular tachycardia. You can hold your breath and cough hard, which may stop the tachycardia. If the pain in the chest or other suspicious parts (back, upper limbs, pharynx, etc.) persists, the attack of acute myocardial infarction cannot be ruled out. It is best to lie on your back, relax as much as possible, take a deep breath slowly and wait for rescue. (Reporter Chen Si)

　　Xinhua News Agency, Hangzhou, September 11th　Question: What you don’t know about the Asian Games: Who will make the rules of the e-sports competition? Can you enter the Olympics in the future?

　　Xinhua News Agency reporters Zhao Jiantong and Ji Jiadong

　　The pace of the Asian Games in Hangzhou is approaching, and the attention of sports fans to various events is gradually heating up. E-sports can be said to be one of the "top streams" of this Asian Games. According to the ticketing scheme, e-sports is not only the most expensive ticket in the final as high as 1000 yuan, but also the only event that requires lottery to buy tickets, so its popularity can be seen.

　　So what are the events in the e-sports competition of Hangzhou Asian Games? Who will make the rules of each event? After the Asian Games, can e-sports join the Olympic family in the future?

　　The e-sports competition of Hangzhou Asian Games was held from September 24th to October 2nd in Hangzhou E-sports Center, China, and produced 7 gold medals. According to official website of Hangzhou Asian Games, there are seven events in this e-sports competition, namely League of Legends, the glory of the king (Asian Games version), Peace Elite (Asian Games version), Knife Tower 2, Dream of Three Kingdoms 2, Street Fighter 5 and FIFA Online 4.

　　In addition to Street Fighter 5, the China team will compete in the other six games. According to industry analysis, the glory of the king, Peace Elite, Dream of Three Kingdoms 2 and other projects will be the potential gold medals for China. Different from the performance events in the 2018 Asian Games in Jakarta, the gold medal of this e-sports event will be included in the medal list.

　　E-sports, as a new type of sports, its competition forms are different with different categories and platforms, and the corresponding schedule system and rules are also various. Fans who are concerned about e-sports will have questions. Compared with individual e-sports events with clubs as the unit, e-sports will become the official event of large-scale intercontinental comprehensive events for the first time. How can teams from different countries and regions in Asia be accommodated?

　　It is reported that the e-sports events of the Hangzhou Asian Games will be decided by the Hangzhou Asian Games Organizing Committee and the Asian Electronic Sports Federation (hereinafter referred to as the "Asian Electronic Sports Federation") through consultation. During the whole preparation process, the copyright owners of the games kept communicating and integrating with the OCA, Asian Sports Federation, Hangzhou Asian Games Organizing Committee and other institutions, and established a set of universal standardized standards applicable to e-sports events in the Asian Games.

　　Among them, the setting that can be used for reference for the future "e-sports included in large-scale comprehensive events" is that the glory of the king and Peace Elite respectively launched the Asian Games version. It is understood that the Asian Games version of the glory of the king has bridged the differences between different versions of heroes at home and abroad, and the peaceful elite has also eliminated the relatively "violent and bloody" escape and shooting. In addition, the two games canceled many commercial settings and some extended gameplay, which also made the game more fair and concise.

　　Judging from the feedback from all parties before the opening of the Asian Games, the formal combination of e-sports and the Asian Games is a win-win marriage for the e-sports industry and traditional sports competitions represented by the Asian Games.

　　Hong Xiao, an expert in e-sports industry and CEO of Perfect World, said: "The entry of e-sports into Asia is a milestone event, which not only means that e-sports will further move towards sports, but also promote the popularization and standardized development of e-sports."

　　In Asia, sports and popularization of e-sports have become a trend. In July this year, the General Assembly of the Olympic Council of Asia was held in Bangkok. It was announced at the meeting that e-sports would become the official event of the 2026 Aichi Nagoya Asian Games. The Asian Sports Federation also announced that it will hold the Asian Cup of Electronic Sports in 2024. In addition, the Pan-American Games held in Chile in October this year will also host the Pan-American E-sports Championship.

　　In the future, can e-sports go further and become an official event of the Olympic Games?

　　International Olympic Committee President Bach said at a press conference in 2020: "Will e-sports be considered for inclusion in the Olympic Games one day? The answer is yes. It depends on when this day comes. "

　　This year, the International Olympic Committee frequently released the signal of "embracing" e-sports. In June, the first Olympic E-sports Week was held in Singapore, which was the first offline event named "Esports" under the International Olympic Committee. In September, the International Olympic Committee announced the establishment of a new e-sports committee, which also triggered many reverie of global sportsmen.

　　In the discourse system of the International Olympic Committee, there is a strict distinction between Virtual Sports and electronic game competition in concept, and in terms of the prospect of entering the Olympic Games, the organization once said that the priority would be virtual sports, such as cycling and taekwondo, which require real physical exercise for participants.

　　Although there have always been strict standards and procedures for the inclusion of new sports, the International Olympic Committee has maintained an open attitude towards the "young wave". From the perspective of skateboarding, break dancing and surfing, it may really be only a matter of time before e-sports enter the Olympics.

Hello, I’m Lu Snake, and today I’m going to talk about football in China!

Speaking of China football, the most important thing recently is that the Football Association has a new head-Song Kai. As a football fan in China, I think this is at least a positive signal, because it shows that the football community in China is trying to improve its own problems and promote the development of football in some way.

Historically, the development of football in China has been plagued by various problems, including mismanagement and corruption. Therefore, changing the president of the Football Association can bring new ideas and directions for the development of football, help solve these problems and promote the healthy development of football in China.

After the new president takes office, he may take a series of measures to improve the football situation in China, including strengthening management, promoting professional development, strengthening the construction of youth training system and improving the quality of coaches and players. From the recent developments of the new head of the Football Association, we can also get a glimpse of it. Then, next, I will sort out the recent events that seem to me to be more important.

1. Debut: "Take youth training as a top priority"

On November 22nd, the second leg of the U15 final in China Youth Championship was held in Weifang, Shandong Province. Football Association President Song Kai, Vice President Xu Jiren and Secretary-General Yuan Yongqing appeared together.

The newest Football Association’s leadership team, which made its first collective appearance, chose youth football matches, fully expressing its attention to youth football. In the words of Song Kai, "China Football Association should take youth training as a top priority." How can we improve the quality of youth training? Song Kai mentioned, first of all, "let the best coaches do youth training", "I have been doing the three big balls in Liaoning for a long time, so I can do some guidance from the policy and system, such as improving the treatment of echelon coaches. In the process of children’s growth, a more competitive competition system is established. "

2. Meeting with AFC President, breaking ice in football foreign affairs.

Song Kai, President of China Football Association, who just arrived in Doha, Qatar, met with Salman, President of AFC, who was also attending the 2022 AFC Awards Ceremony. This is the first time that Song Kai has face-to-face communication with the president of the Asian Football Association as the president of the China Football Association, and it also marks the beginning of the new China Football Association to break the ice for football foreign affairs and take an important first step.

It is understood that during the meeting, Salman reiterated to Song Kai that the AFC will continue to cooperate with the China Football Association to support them in revitalizing football in China.

Subsequently, in its important position in official website, the AFC focused on the meeting between Song Kai and Salman with the title "AFC President praises the football development in China". The AFC quoted Salman as saying: "The AFC will unswervingly strive to make football the number one sport in the Asian continent. I believe that China Football Association can help China football to a higher level under the leadership of President Song Kai. We will also work together for this. " Salman also said: "What is exciting is that we see the determination of the new leadership of China Football Association to develop football and promote the progress of football in China. Football still has great development potential in China. "

3. Study and open the foreign aid policy of the Super League to increase the appreciation of the league.

After Song Kai took office, in view of the situation of the Super League, he said that he would strive to create a professional league that people are satisfied with, and study the foreign aid policy of opening the league against the AFC. At present, the foreign aid policy of the Super League is 654, and his new policy is expected to be "51", that is, five non-nationals and one Asian foreign aid can play at the same time. The implementation of this policy will increase the internationalization and fierce competition of the league, attract more excellent players to China, improve the competitiveness of the league, and at the same time, improve the enjoyment and entertainment, so that fans can enjoy more exciting games.

Finally, I hope the new president can take effective measures to promote the healthy development of football in China, so that we fans can pay more attention to the future of football in China with pride.

If you have any expectations for China football or what do you think of the new head of the Football Association, you are also welcome to leave a message in the comment area for discussion.

　　Henan urgently applied for calling "rain-increasing aircraft"

　　The deputy director of the Provincial Meteorological Bureau communicated with netizens online, saying that the "rain-increasing aircraft" could be in place in the middle of this month, and artificial rainfall and snow could be carried out when the time was ripe.

　　■ Business Daily reporter Guo Fushou

　　In the face of this year’s severe drought, meteorological stations at all levels in our province have used high technology-a new generation of weather radar to monitor weather changes. In the middle of this month, "rain-increasing aircraft" can also be put in place.

　　Yesterday afternoon, Zhao Guoqiang, deputy director of the Provincial Meteorological Bureau, visited the portal website of the provincial government and the live broadcast room of Dahe. com, and exchanged views with netizens on issues such as "fighting drought with all efforts to protect seedlings and win a bumper harvest".

　　A new generation of weather radar helps drought resistance

　　"After the drought, meteorological departments at all levels in the province have been closely monitoring the weather changes, and a new generation of weather radar is on.

　　Zhao Guoqiang said that they have also strengthened drought monitoring and satellite remote sensing monitoring.

　　Since February 3, 2009, the precipitation and precipitation infiltration depth have been observed intensively. According to the monitoring and analysis, the Provincial Meteorological Bureau issued an orange warning signal for drought on January 7, and upgraded the drought warning to red on January 29, prompting relevant departments and units to do emergency work to prevent drought, and also providing meteorological basis for the provincial party committee and government to organize leaders to carry out drought-resistant wheat watering work.

　　580 shells and rockets to alleviate drought

　　"According to the arrangement of the Provincial Meteorological Bureau, all parts of the province have inspected anti-aircraft guns, rocket launchers and other equipment that carry out weather modification operations. On the first day of work after the holiday on February 1, a special person and a special car were sent to Luoyang and Jiaozuo. " Zhao Guoqiang said.

　　On the night of February 1st, the artificial influence workers in Sanmenxia, Luoyang, Jiyuan, Jiaozuo, Anyang and other cities stuck to the gun point, and timely carried out ground anti-aircraft guns and rockets to artificially increase rainfall and snow. A total of 18 anti-aircraft guns and 26 rockets were dispatched, and 400 shells and 180 rockets were fired. As of 08: 00 on February 2, there was light rain and snow in the affected area, which alleviated the drought to some extent and reduced the fire risk level of the forest area.

　　The "rain enhancement plane" can be put in place in the middle of this month.

　　Zhao Guoqiang said that according to the requirements of the provincial party committee and government, the Provincial Meteorological Bureau formed the 12th supervision team led by the bureau leaders to guide the work of drought-resistant wheat watering in Puyang. At the same time, the relevant business units of the Provincial Meteorological Bureau and the meteorological bureaus of provinces and municipalities also sent experts, technicians and mobile soil moisture measuring instruments to the fields to provide technical guidance and on-site services for farmers.

　　"Not only that, but also urgently call the rain-increasing aircraft." Zhao Guoqiang introduced that he was also actively in contact with the Air Force Department on matters related to the early adjustment of aircraft. On February 3rd, the letter from the provincial government to apply for a rain-increasing plane from the Air Division has been delivered by a special person. It is expected that the rain-increasing plane will be in place in the middle of this month.

　　Credit card irrigation makes great contributions. Farmers look forward to "well-to-well communication"

　　■ Business reporter Hu Zhiqiang correspondent Sean

　　It saves money and effort to water the land and swipe the card. In the face of the once-in-50-year drought in the whole province, farmers’ friends have a heartfelt heart: the grassroots need benefits like "well-connected".

　　Farmers can water the land by swiping their cards.

　　Yesterday morning, Meng Yongsheng, a villager from Menglou Village, Xilingsi Town, Sui County, came to the transformer room at the east end of the village. He pushed on the knife, took out a card from his coat pocket, pointed it at the electric meter, and only heard a bang, "It’s time to water the ground …" Meng Yongsheng ran to his wheat field with a smile. At this time, the plastic pipe in the ground had already come out.

　　Meng Yongsheng said that before the "well-to-well connection" project was realized, it would take him half a day to pour it back to the ground.

　　Meng Yongsheng’s "well-to-well connection" project is a pilot project for the state to support key agricultural power projects. Meng Xiande, secretary of the Party branch of the village, said that at present, more than 800 mu of wheat in the village has been watered. If it is not the "Jingjingtong" project, I am afraid that many farmers will be worried about the lack of power lines and meters.

　　Save labor, time and land.

　　Li Xiangyu, director of the production planning department of Suixian Power Supply Company, introduced that the "well-to-well connection" project is also called "platform area", which refers to the well area controlled by a transformer, and is referred to as "platform area" for short. In the implementation of this project, there is no wire post in the wheat field, and the land can be watered by swiping the card. His benefits are not only labor-saving, time-saving but also land-saving.

　　In the implementation, the cable is buried more than 1 meter deep underground, so that the line loss is greatly reduced without wind and rain; Secondly, the outdoor transformer is seriously stolen, the transformer is installed indoors, and the door is equipped with monitoring and alarm equipment, which can effectively prevent theft.

　　Li Xiangyu introduced that the company invested a total of 4.95 million yuan last year. At present, there are 34 "well-to-well" projects in the county, benefiting more than 23,000 mu of cultivated land in this year’s drought relief work.

　　The small card introduced by Li Xiangyu is the "IC" card. You can pay the electricity fee to the Dianguanzhan for recharging. After watering the land every time, you can swipe your card again, which shows the electricity consumption and balance of farmers. At the same time, the machine will automatically settle according to the charging standard stipulated by the state.

　　I look forward to more investment in these projects.

　　"I don’t know, I’m scared." This is a proverb in eastern Henan. In the past two days, the Business Daily reporter visited four townships in Sui County. Whether there is a village committee of the "Jingjingtong" project, the growth of wheat seedlings can be described as two days.

　　Under the background of the same drought year, in the implementation area of the "Jingjingtong" project in Menglou Village of Xilingsi Town, the growth of wheat seedlings is generally better than that of other village committees. Jiangang Township is a township with good soil quality in Sui County, and Yanzhuang Village in this township is also a beneficiary village of "well-connected". Yesterday afternoon, villager Ding Baoquan watered his own wheat for the second time, and at the same time, he applied fertilizer first, which effectively enhanced the growth of wheat seedlings.

　　Compared with the village committee with the "Jingjingtong" project, Wang Peichu, a villager in Li Dazhuang, Xilingsi Town, has a strong desire for "Jingjingtong". He said that if there is this project this year, he and other villagers will respond positively.

　　In response to farmers’ voices, Li Xiangyu said that in recent years, the state has increased its investment in power infrastructure. If the funds allocated by higher authorities are normal, the county needs more than 1,300 "stations", and the transformation task can be completed in two to three years.

　　"By then, farmers in the county can water their crops with their credit cards." Li Xiangyu said.

　　Yellow River Defense General:

　　Stop the Yellow River from cutting off.

　　Business News (Reporter Guo Fushou) Due to the severe drought in Henan, Shanxi, Shaanxi and Shandong provinces, the Yellow River Flood Control and Drought Relief Headquarters (Yellow River Flood Control Headquarters) held an emergency meeting and issued instructions to support drought relief in the basin to ensure the safety of the Yellow River’s ice prevention, drinking water safety and food safety in the Yellow River water supply area, and ensure the continuous flow of the Yellow River.

　　Xiaolangdi adjustable water quantity

　　Half less than the same period last year.

　　Yesterday, news came from the Yellow River Committee that the Yellow River Flood Control and Drought Relief Headquarters held an emergency special meeting on drought relief. In the case that the main stream of the Yellow River is dry, it is necessary to do everything possible to raise water sources to support the drought relief in the basin provinces.

　　According to the latest hydrological data, from November last year to January this year, the inflow of water from the main inflow areas of the Yellow River Basin was 5.244 billion cubic meters, 13% less than the multi-year average, of which 950 million cubic meters came from the middle reaches of the Yellow River, 51% less than the multi-year average; The downstream inflow was 141 million cubic meters, 76% less than the multi-year average. Affected by the continuous drought, the adjustable water volume of Xiaolangdi Reservoir in the Yellow River is only 1.71 billion cubic meters, 1.74 billion cubic meters less than the same period last year.

　　"In order to support drought resistance in Henan, Shandong and other provinces, the Yellow River Flood Control and Drought Relief Headquarters strengthened consultations, closely tracked the development of downstream ice conditions and droughts, and scientifically dispatched and increased water consumption indicators in time when the incoming water was dry." The relevant person in charge of the Yellow River Committee said that it is necessary to ensure the safety of the Yellow River against ice, the safety of drinking water and food in the Yellow River water supply area, and ensure the continuous flow of the Yellow River.

　　Issue an orange warning of drought

　　The reporter also learned that in view of the severe drought in several provinces in the Yellow River Basin, especially in Shanxi, Shaanxi, Henan and Shandong provinces, according to the provisions of the Yellow River Basin Drought Relief Plan (Trial), the Yellow River Defense General has further upgraded the warning level. From now on, the regional drought in the Yellow River Basin will be upgraded from a yellow warning to an orange warning, and a secondary emergency response will be launched.

　　Henan Yellow River Affairs Bureau:

　　It attracted 322 million cubic meters of Yellow River water.

　　Quench thirst of wheat in our province

　　Business News (Reporter Guo Fushou correspondent Zu Shibao Liu Tian) Yesterday, the reporter was informed that the Henan River Affairs Bureau held an emergency meeting on drought-resistant wheat irrigation on the 3 rd, proposing to make full use of the Yellow River water and go all out to ensure the demand for drought-resistant wheat irrigation in Henan along the Yellow River.

　　Niu Yuguo, deputy commander of the Flood Control and Drought Relief Headquarters of Henan Province and director of the Yellow River Affairs Bureau of Henan Province, said that from November last year to January this year, more than 20 sluice gates for diverting water from the Yellow River were opened one after another, and the cumulative water supply to Henan along the Yellow River was 316 million cubic meters. The maximum daily water intake for drought-resistant wheat irrigation reached 130 cubic meters per second. Among them, the emergency water diversion in January was 162 million cubic meters, which was 120 million cubic meters more than the same period of last year, which was the highest water diversion in the same period since 1980.

　　In January this year, our province diverted 162 million cubic meters of Yellow River water in an emergency, setting a new high for the same period since 1980. The Yellow River Affairs Bureau of Henan Province applied to the Yellow River Committee for a water plan to divert 322 million cubic meters of water to the Yellow River in February, with an average diversion flow of 133 cubic meters per second, which has been approved by the Yellow River Committee, the highest application and approval for the same period since 2000. This means that 322 million cubic meters of Yellow River water will be used to water wheat in our province. henan business daily

　　Give you a heads-up

　　Every summer, all kinds of seemingly eloquent "popular science" are "listed" simultaneously with big and red cherries.

　　Recently, a video about the quality and safety of cherries spread on the Internet, saying that "99% of cherries on the market use swelling agents. Normal cherries can only grow to 12-mdash; The weight of 13 grams can be doubled with swelling agent. If there is no kernel in the cherry pit, the hollow one is medicated &hellip; &hellip;”

　　What is the swelling agent that is often named? Is there really a miraculous effect in the rumor? What factors are related to the size of the cherry? To this end, the reporter visited experts in the agricultural field and consulted people on issues of concern.

　　No food safety incidents caused by it have been found yet.

　　"The swelling agent is a plant growth regulator. In the process of cherry growth, in order to improve pollination rate and fruit setting rate, cherry planted in greenhouse usually needs to use swelling agent; Cherry cultivated in the open field does not need to be used. " Wang Qiang, a researcher at the Agricultural Products Quality and Safety Risk Assessment Laboratory (Hangzhou) of the Ministry of Agriculture and Rural Affairs, told the reporter that at present, open-field cherry is the mainstream cultivation mode in China. According to this calculation, it is indeed possible to use plant growth regulators such as bulking agents in cherry market, but the utilization rate should be less than 50%.

　　How do plant growth regulators play a role in the production of fruit and vegetable products?

　　"Plant growth regulators have similar effects to plant hormones, which can stimulate the division and growth of plant cells. The difference is that plant growth regulators are artificially synthesized by scientists and modified to make their activities stronger than plant hormones." Xu Dong Hui, a researcher at the Institute of Vegetables and Flowers of the Chinese Academy of Agricultural Sciences, said.

　　In terms of management, since 1997, according to the Regulations on Pesticide Management, plant growth regulators have been managed as pesticides.

　　According to the relevant person in charge of the Ministry of Agriculture and Rural Affairs, at present, there are nearly 40 registered plant growth regulators in China. There are more than 100 kinds registered and used internationally. Approved and registered plant growth regulators should formulate technical specifications for safe use, including medication period, dosage, application method, scope of use, matters needing attention and safety interval, and clearly mark them on product labels to guide farmers to use them reasonably. In addition, a series of residue tests should be carried out for registered products, and residue limit standards and reasonable use criteria should be formulated according to data such as residue tests to ensure the quality and safety of agricultural products. Since 2015, the Ministry of Agriculture and Rural Affairs has conducted a risk assessment of plant growth regulator residues in agricultural products, and the results show that the average residue value of plant growth regulators is only 0.001&mdash; 0.034 mg/kg, the risk of dietary exposure is very low, and the product quality and safety are guaranteed.

　　Experts said that in terms of safety, there have been no food safety incidents caused by plant growth regulator residues in the world so far. In China, agricultural products that have been applied with plant growth regulators are also very safe for consumers. Compared with other pesticides, although plant growth regulators are included in the management of pesticides, they are not pesticides for treating diseases, insects and weeding in the traditional sense. Their products are of low toxicity, and some of them are even listed as exempted substances without setting residue limits because they are almost nontoxic. For example, the toxicity of chlorfenuron commonly used in expanded fruits (LD50 > 4,918 mg/kg) is lower than that of salt (LD50 = 3,200 mg/kg). In addition, because the amount of plant growth regulator is small, excessive use is easy to produce adverse effects, and farmers can not use it in large quantities, so the residue of plant growth regulator is low.

　　Fruit size is determined by many factors.

　　Then, what factors are related to the size of cherry fruit, and can the swelling agent "double" the fruit?

　　According to experts, large cherry and seedless cherry are related to variety characteristics, cultivation measures and the use of plant growth regulators.

　　Xu Donghui told reporters that "Meizao" is the largest fruit among the cherry varieties at present. This variety of cherries has the characteristics of large fruit shape, full and sweet taste. Under normal circumstances, the single fruit weight of "Meizao" is 8-mdash; 12 grams, which can reach 16-mdash under special cultivation methods; Twenty grams.

　　"A sweet cherry variety selected in China &lsquo; Red light &rsquo; Under normal circumstances, the weight of a single fruit can reach 11-mdash; Fifteen grams. From the point of view of drug control, it has been reported in literature that treating cherry with plant growth regulator gibberellic acid can increase the weight of single fruit by about 15%&mdash; 30%, the swelling effect is limited. " Wang Qiang said.

　　So, does cherry seedless mean that it has been treated with swelling agent? Wang Qiang said, this statement is too absolute. Although it is reported in the literature that cherry stones will be hollow after being treated with gibberellic acid at a certain concentration, it is not necessarily 100% seedless after being treated with gibberellic acid at a low concentration. In addition, the causes of cherry hollowness are natural abortion or other possibilities, not necessarily because of the use of gibberellic acid and other drugs.

　　Xu Donghui explained that in order to improve the pollination rate and fruit setting rate of cherries, fruit farmers will apply gibberellin and other plant growth regulators at flowering stage, which may also cause seedless fruits and nuts, but this will not affect the safety of cherries.

　　Fancy left hand

　　Quiet right hand

　　Have a rest and enjoy peace by the water.

　　If you come to Suqian alone, start a quiet journey of one person. Here, you can not only feel the modernity and prosperity of the city, but also appreciate the ecology and tranquility of the Suqian section of the ancient canal.

　　Soaring thousands of miles, sighing about Qian Qian.

　　The boat of the canal, from south to north, is endless. Looking at the bridge, the past of the city, countless beautiful scenery.

　　Suqian is born of water and prospers because of water. The Beijing-Hangzhou Grand Canal passes through the territory and meanders. Looking at the two sides of the canal, the green water sets off the greenery, and high-rise buildings rise not far away, and a different feeling rises from the bottom of my heart.

　　Stroll through the scenic belt of Suyu Central Canal, walk into the most beautiful canal coastline in Siyang, indulge in the tenderness of the river, enjoy the scenery along the way and feel the leisurely and slow life of Shuicheng with the boat.

　　"Bridge" meets Xi Chu and listens to a secret language.

　　The winding Grand Canal is the "mother river" of Suqian people. Today, when the banks of the canal are becoming more and more beautiful, bridges span the banks of the canal, bearing the memories of countless Suqian people.

　　"Bridge" meets Suqian and listens to the secret language of Canal Bridge. How many bridges are there in Suqian section of Beijing-Hangzhou Grand Canal? Let’s count them.

　　North Ring Canal Bridge, Nanjing Road Canal Bridge, Development Avenue Canal Bridge, Yanghe Bridge, Canal Culture Bridge, Zaohe An Lan Bridge and many other canal bridges are either classical or fashionable, and the stories of the city are recorded in the joyful songs of canal water. Overlooking from the sky, is this place of Xi Chu particularly attractive?

　　Perhaps, when you meet a canal bridge unexpectedly, someone is watching you from a distance when you are standing on the bridge watching the scenery.

　　Seek seclusion by the river and explore the style of Shuicheng.

　　As far as you can see, there are many cultural attractions beside the canal bridge. Canal History Museum, outdoor theater, sightseeing tower, outdoor cafe, cruise terminal ….. Garden beauty and characteristic buildings are embedded in it, which enriches the wonderful swimming along the river.

　　Cross the canal bridge and walk along the riverside road to a street in the city, turning quiet into excitement. A tall building next to another, an alley after another, a new look, all tell the story about Suqian.

　　In the 2008 Beijing Olympic Games, Phelps’ eight gold medals broke the 36-year-old record that was once considered inaccessible by swimmer Mark Spitz. Phelps participated in men’s 400m individual medley, men’s 200m individual medley, men’s 100m butterfly, men’s 200m butterfly, men’s 200m freestyle, men’s 4x100m freestyle relay, men’s 4x200m freestyle relay and men’s 4x100m medley relay successively at the Beijing Olympic Games, winning eight gold medals, breaking seven world records, and gaining fourteen individual medals. Phelps set an insurmountable record for others. China News Agency issued Du Yang photo

　　On the morning of August 10th, on the first day of the swimming final of the Beijing Olympic Games, China’s Zhang Lin won the silver medal in the men’s 400m freestyle, while South Korean Park Tae hwan and American Zhan Sen won the championship and the third place respectively. This is also the first time that a male athlete from China has won an Olympic medal. China News Agency issued Du Yang photo

　　BEIJING, Aug. 16 (Xinhua) Title: Swimming Inventory: The United States and Australia are "gender imbalance" and the China Navy is no longer "water"

　　Author: Lu Chunyan

　　On August 17th, "prodigy" michael phelps led the American team to win the gold medal in the men’s 4×100 medley relay final, and won his eighth gold medal in Beijing. This marks the end of the swimming event in Beijing, which is second only to the 46 gold medals in track and field. The "Water Cube" of this Olympic Games has turned into a "Water Cube", and the world record has been labeled as "fragile". The United States and Australia have their own gains in competing for hegemony, and the China Navy has also seen hope in its progress.

　　"Yang Prosperity and Yin Decline" VS "Yin Prosperity and Yang Decline" The United States and Australia strive for hegemony and "gender imbalance"

　　Compared with the Athens swimming event, the gorgeous performance of the American swimming team in the Water Cube can be described as "dominating the world". The results of 12 gold medals, 9 silver medals and 9 bronze medals left Australia’s 6 gold medals, 6 silver medals and 8 bronze medals far behind.

　　However, Australia, suppressed by the United States, should also be respected. After all, today’s swimming world has the strength to challenge the American team, and it is Australia. The remaining 14 gold medals were divided among 11 countries, with Britain, Germany and Japan each taking two, and China, Brazil, Tunisia, South Korea, the Netherlands, Italy, France and Zimbabwe each taking one.

　　The distribution of gold medals in the American swimming delegation showed a situation of "Yang flourishes and Yin declines". Male athletes won 10 of the 12 gold medals, and they monopolized five-eighths of the Olympic men’s swimming events under the leadership of Phelps. Only coughlin and Sony saved a little face for American female swimmers.

　　Unlike the United States, which relies on men’s events, Australia has completely embarked on the "female route". All six gold medals in the "Water Cube" were won by female athletes, while male athletes only got three silver medals and three bronze medals. Compared with the American team, Australia’s "Yin flourishes while Yang declines" seems to be more thorough.

　　"Yin flourishes and Yang declines" VS "Yang flourishes and Yin declines", and there is a gender imbalance between the United States and Australia. In August, a gender war was staged at the National Aquatics Center.

　　World records are labeled as "fragile" and old records are turned into rarities.

　　The Water Cube staged a "war epic" against the "world record" from the first match day when two world records were born in the four finals. Seven of the eight gold medals won by the American "prodigy" rewrote the world record, and even the only gold medal in the 100m butterfly, which was "lighter" than the other seven gold medals, was almost the same as the world record. What’s more, Zimbabwe’s Coventry started a record-breaking trip in the preliminaries.

　　The birth of one new world record after another makes the audience seem to have formed "aesthetic fatigue" on the records, and a large number of newly released records really test everyone’s memory. All of a sudden, those records that have been preserved have become rare, and they can still be "immune" when such large-scale good results are released, which shows the preciousness of these old records.

　　Men make history. China swims in the "Water Cube" and sees hope.

　　China swimming, dormant in the downturn, finally saw the hope of recovery in the "Water Cube". One gold, three silvers, two bronzes, three 4th, one 5th, one 7th and one 8th in this Olympic Games are enough for China to get a performance score of 80 points. All these have become the best evidence that Zhang Yadong, the head coach, pointed out that China Water Army began to walk out of the trough.

　　Liu Zige, Jiao Liuyang and other young players have changed the situation in 2007, and Zhang Lin’s silver medal has also shown us the progress of male athletes.

　　The most significant one is the silver medal in the men’s 400-meter freestyle from Zhang Lin. Even in Barcelona, the most splendid swimming place in China, the male swimmers from China failed to grab a gold and a half silver. Zhang Lin won the first medal in Olympic history for men’s swimming in China with his own efforts and national support.

　　However, we should also see that China’s swimming strength is still far from the collective advantage of the United States and Australia, and the highlights are only concentrated in three or two events. Moreover, China’s swimming does not have the domineering and winning strength of the United States and Australia.

　　However, I still believe that "a single spark can start a prairie fire", and I hope that China Swimming, which finds a breakthrough point, can make a name for itself in the Olympic swimming field through its own efforts.

　　"God" Phelps, the first man in the centennial Olympic Games, ascended the throne in Beijing.

　　After winning the NBA championship three times in a row, the media commented that "Jordan is God wearing a jersey and playing"; Once again won the NBA championship for three consecutive times, the media commented that "even God can’t beat Jordan in his jersey". Therefore, even with bare arms, God may not be able to win eight gold medals in an Olympic Games, but the "prodigy" did it.

　　Michael phelps seems to have come to Beijing to break the record. He has seven world records in eight competitions, a single Olympic gold medal record with eight gold medals and an individual Olympic gold medal record with fourteen gold medals. Phelps is proving himself to be the "Water Cube" and the king of Olympic history with figures that others can’t match.

　　When Bolt broke the world record and won the 100-meter new Olympic champion, the media who liked the new and hated the old questioned the ownership of "the best athlete in Beijing Olympic Games". In fact, this is a very simple arithmetic problem. Can’t nine records beat one record? The record of eight gold medals of "prodigy" was accumulated in the Olympic Games for a hundred years, but who can say that the record road of 9.69 seconds can be kept fresh in a hundred years?

　　For 23-year-old Phelps, the Beijing Olympic Games is probably just a "walk" of his brilliant career, because he will be 27 years old in four years, which is the best age for professional athletes. At that time, he will give the world the expectation of several Olympic gold medals. (End)
