＂One spray and more promotion＂, new technology, new equipment … ＂Make a fist with your fingers＂ to win the tough battle against disasters and harvest.

CCTV News:Autumn grain is an important part of grain production in the whole year. The latest agricultural situation dispatch of the Ministry of Agriculture and Rural Affairs shows that the area of autumn grain in China has increased steadily this year, and the current growth trend is generally normal.

At present, spring corn in Northeast China is in grain filling stage, and rice enters booting to heading stage. Summer maize in Huang-Huai-Hai successively sprouted males and spun silk, and summer soybean entered the flowering and pod-setting stage. Mid-season rice in the middle and lower reaches of the Yangtze River is from jointing to booting; Over 80% of double-cropping late rice planting in South China has entered the critical period of field management.

Zhu Juan, director of the Agricultural Situation Division of the Planting Management Department of the Ministry of Agriculture and Rural Affairs, said: "beginning of autumn is approaching, and there are still more than 60 days before the large-scale harvest of autumn grain. Autumn grain crops have entered the critical period of heading and grouting, which is also a critical moment for flood control and disaster relief. At present, most of the main producing areas have high temperatures, high precipitation, sufficient soil moisture, and normal crop growth. It can be said that there are still foundations and conditions to win a bumper harvest. "

According to the agricultural situation dispatch of the Ministry of Agriculture and Rural Affairs, since the beginning of summer, there have been several rounds of heavy rainfall in the southern region, and some areas of the Huang-Huai-Hai region have been dry during the summer sowing period. Recently, some areas of Henan, Hunan, Liaoning and other provinces have suffered severe floods, which have brought certain impact on the autumn grain production in some areas, but from a national perspective, the growth of autumn grain seedlings is generally normal.

Zhu Juan said that the Ministry of Agriculture and Rural Affairs will pay close attention to the hardest-hit areas in the main producing areas, every grain variety and every key link, send scientific and technological teams to sink into the front line, guide the implementation of key measures such as "spraying more and promoting more" in autumn grain, and strive to win the tough battle against disasters and harvest.

Implementing "one spray and more promotion" in the main producing areas to promote the strong seedlings and stable growth of autumn grain crops

Recently, autumn grain crops are heading and filling one after another, which is the key window period for stable and increased production. The main producing areas have stepped up the implementation of "one spray and more promotion" to promote the strong seedlings and steady growth of autumn grain crops.

"Spraying more with one spray" means spraying foliar fertilizer, growth regulator, insecticide and bactericide for crops at one time, so as to achieve the purpose of promoting growth and stability, post-disaster recovery, grain filling maturity and yield increase. The central government has allocated 2.037 billion yuan for disaster prevention and relief in agricultural production to support the implementation of "one spray and more promotion" for autumn grain crops.

Although more than 66 million mu of autumn grain in Shandong has experienced early drought and sudden changes in drought and flood, it is growing well as a whole due to timely field management. The local government is stepping up efforts to allocate more than 110 million yuan from the central government to achieve the implementation of "one spray and more promotion" in various places. Xintai city organized 11 professional flying defense teams and introduced 6 high-performance unmanned aerial vehicles, which nearly doubled the operating efficiency.

Bao Wei, chief of the crop department of xintai city Modern Agricultural Development Service Center, said: "At present, 401,000 mu of corn in the city is in a period of high incidence of pests and diseases. We should seize this window period to focus on preventing and controlling pests and diseases such as southern rust of corn, and strive to complete the first round of unified prevention and control before mid-August."

At present, 1.9 million mu of rice in Huoqiu County is in the jointing and tillering stage, which is also a critical period for pest control. Following the principle of "early treatment, small treatment, and prevention is more important than treatment", more than 100 professional plant protection teams were organized to go to the fields and strive to control more than 60% of rice in the county within a week.

Wang Rensong, a large grain grower in Xihu Township, Huoqiu County, said: "The prevention and control window period is about one week. If the control is early, the eggs have not occurred, and if the control is late, the Chilo suppressalis has already got into the rice, so it is not easy to fight. Therefore, we found several drones and got it in half a day, laying a solid foundation for the harvest of autumn grain. "

Increase the popularization of new technology and equipment to promote stable and high yield of autumn grain

In addition, in the process of autumn grain production, all localities have increased the promotion of new technologies and new equipment to promote stable and high-yield autumn grain.

The area of autumn grain in Henan this year is stable at more than 76 million mu. In the demonstration area of 300,000 mu of high-standard farmland in Xunxian County, rows of corn grow gratifying. This year, the local planting method of "wide and narrow rows and close planting+dropper" not only ensures the natural ventilation and light transmission of corn, but also improves the supply of water and fertilizer for corn.

Dong Wenquan, an agronomist of the Agricultural and Rural Bureau of Xunxian County, Hebi City, said: "Now corn is in the pollination period and grain formation period, which is also the most critical period for corn management. During this period of time, we should hurry to water and fertilize, and generally urea can be applied to every mu of land. 20 kilograms, it is best to add some phosphate fertilizer, potassium fertilizer or trace element water-soluble fertilizer, so that the nutrition is more complete. "

In Tongcheng City, Anhui Province, the local green pest control technology was promoted to reduce the use of pesticides. In this demonstration area of green prevention and control of rice pests and diseases, rows of "new moth traps" are scattered. These new traps installed a month ago have become green "guardians" of rice fields, which are used to trap and kill pests such as rice leaf roller in the field.

In Heilongjiang Beidahuang Junchuan Farm, agricultural technicians are using spore trap to capture the harmful flora in the field, and at the same time, analyzing the growth of rice by multi-spectral analyzer on the plant protection patrol machine. This three-dimensional monitoring of "air-ground combination" makes plant protection operations more accurate and efficient.
