[Changle Daily] Changle County organized and carried out the "one spraying and multiple promotion" flight prevention operation of corn

Changle Rongmei News (reporter Qin Bo and Feng Haibin) At present, it is a critical period for the late management of autumn grain. Our county has organized and carried out the "one spray and multiple promotion" flight prevention operation of corn, laying the foundation for the harvest of autumn grain.

In Taipingguanzhuang Village, Yingqiu Town, the plant protection UAV took off steadily, flew into the operation area according to the set work route, carried out the unified control of pests and diseases on corn, and sprayed drugs accurately and evenly on each corn.

Flying hand Liu Shanfeng said: "The UAV spraying not only liberates the labor force, but also greatly improves the efficiency. It sprays 100 mu of land an hour, 700 to 800 mu a day. Its atomization effect is much better than that of manual spraying. High stalk crops such as corn can also be directly hit from the top to the root."

It is understood that "one spraying and multiple promotion" is the key technology for field management of autumn grain crops in the middle and later stages. By spraying a mixture of insecticides, fungicides, growth regulators, etc. at one time, it can achieve multiple effects such as promoting seedling growth, post disaster recovery, grain filling maturity, and improving yield per unit area, so as to ensure stable and high yield of autumn grain. This year, our county is expected to cover an area of more than 60000 mu.
