China News Service, Qiyang, September 29 (He Yanfei, Feng Xiao) It is now a critical period for the formation of late rice production, and it is also a stage prone to high incidences of pests, diseases, and meteorological disasters. In order to effectively respond to the impact of drought and floods, cold dew and windy weather, effectively prevent the spread of pests and diseases such as rice planthoppers and stem borers, and make every effort to stabilize the autumn grain production situation, Qiyang, Hunan Province launched a comprehensive aerial defense operation for autumn grain stress resistance and disaster prevention, and concentrated on unified late rice prevention and control operations to ensure the stable and increased production of late rice in the city's 85,600 acres.
In the contiguous rice fields in Lianyi Village, Wenmingpu Town, Qiyang City, plant protection drones shuttle and operate accurately, and the finely atomized liquid evenly covers the leaves and base of the rice plants, carrying out all-round pest control and rice plant maintenance. Gui Qin, the head of Qiyang Hope Tiantian Modern Agricultural Machinery Professional Cooperative, was stationed at the operation site throughout the entire process to strictly control operation safety and quality.

"We strictly implement the operation specifications, check the status of the equipment item by item before taking off, and keep an eye on the flight route in real time during the operation to ensure that every rice field and every inch of the rice plant is properly prevented and controlled, leaving no blind spots." Liu Bin, an agricultural machine operator, said that the flight prevention operation accurately controlled the time and standards and avoided operations during the high temperature period at noon to ensure the prevention and control effect to the greatest extent. At the same time, a re-spraying mechanism was established. If there is moderate to heavy rain within 24 hours after the operation, the re-spraying operation will be carried out in a timely manner to ensure that the prevention and control effect is not compromised.
Compared with the traditional manual pesticide application mode, UAV flight control has the advantages of uniform spraying, high efficiency, and precise prevention and control. It effectively solves the pain points of manual pesticide spraying such as missed sprays, heavy sprays, and delayed operations. It adapts to the needs of large-scale and contiguous rice field management and protection, and greatly improves the standardization level of late rice field management and protection. According to Guiqin, traditional manual pesticide application only covers an area of more than ten acres in a single day, while UAV flight control can cover more than 300 acres in a single day. The operation efficiency is increased by dozens of times, the pesticide solution is more evenly distributed, and the pest control effect is significantly improved.
This unified aerial control of late rice was coordinated and implemented by a professional social service organization. Foliar fertilizers, growth regulators and aerial control auxiliaries were applied in a unified proportion, focusing on concentrated spraying in core demonstration areas and areas with heavy pests and diseases, to achieve simultaneous advancement of disease and pest control and stress resistance and quality improvement of rice plants.
In order to strictly observe the quality of operations and prevent "empty flying and missing flying", the Qiyang Municipal Agriculture and Rural Affairs Bureau established three special technical guidance groups to supervise and supervise the entire process in the fields, record the operation status in real time, improve the work ledger, and strictly control the quality of flying prevention.
Chen Haisong, director of the Plant Protection and Phytosanitary Station of the Qiyang Municipal Agriculture and Rural Affairs Bureau, said that this year the city has selected 6 professional prevention and control service companies to coordinate the deployment of 30 unmanned plant protection machines to carry out aerial prevention operations on a regular basis. All rice field workers are required to Aerial control operations must be completed before the milk-ripening stage of late rice and before the wax-ripening stage at the latest to effectively prevent premature aging of rice plants and reduce the number of diseases and insect pests in the field. At the same time, a mechanism of verification first and then subsidy is implemented to ensure the effectiveness of aerial control with strict quality control.
At present, the city's late rice aerial control operation is being advanced in an efficient and orderly manner, with an average daily operating area of 15,000 acres. It is necessary to prevent all late rice in the entire region without leaving any dead spots, and strive to build a solid foundation for stable, increased yields and bumper harvests of autumn grains.
