Spraying drones for “flying defense” to escort rice

Three minutes, seven minutes in charge. At present, it is a critical period for rice growth and the best time for disease and pest control. In recent days, Sinan County, Guizhou Province has been seizing agricultural opportunities and actively carrying out rice disease and pest prevention and control work. It has made full use of plant protection drone “flying prevention” operations, precise pesticide application, and combined green prevention and control with unified prevention and control. This has made field management easy, efficient, energy-saving, and environmentally friendly, ensuring high grain yield and increased income for farmers.At the 1200 acre rice planting base located in Airport Dam, Tangtou Town, Sinan County, there are endless stretches of green rice, resembling green waves, forming a beautiful scenery. Accompanied by the sound of rotor rotation, two plant protection drones rose into the air under the operation of technicians, flying at a constant speed along the rice field. The sprinkler under the fuselage sprayed white atomized pesticides evenly onto the rice field, putting a “protective coat” on the rice in the field.Due to the relatively high temperature during this period, we carry out plant protection drone ‘flying defense’ operations from 7 am to 11 am and from 4 pm to 7 pm in the afternoon. We can complete 600 to 800 acres in a day, which is quite efficient, “said Cheng Chaoyuan, a drone operator at Sinan Hemufu Agricultural Machinery Specialized Cooperative.It is understood that the operational efficiency of a plant protection drone is more than 20 times that of manual spraying, which can reduce the use of pesticides by more than 30%. Compared to manual spraying, the “fly defense” of a plant protection drone is more efficient, safe, economical, and environmentally friendly.In addition, in response to the growth trend and disease occurrence patterns of rice in the fields this year, the Agricultural Service Center of Tangtou Town actively cooperates with the Agriculture and Rural Bureau of Sinan County to carry out plant protection drone flight prevention operations. Through the advantages of large-scale centralized services, low toxicity, efficient, and green environmental protection pesticides are purchased, and professional services for integrated prevention and control of rice diseases and pests are implemented, reducing the pressure of non-point source pollution in farmland and water bodies, and promoting green prevention and control of rice diseases and pests.This year, diseases and pests such as the rice stem borer and rice leaf roller have arrived relatively early, and the county agriculture and rural bureau has also put drugs and drones in place as soon as possible, allowing our rice to be effectively protected. “Yang Xiufeng, deputy director of the Agricultural Service Center in Tangtou Town, Sinan County, said that efficient and fast plant protection drone flight prevention has shown a” technological model “in field management, effectively improving the efficiency of disease and pest control, Reducing pesticide use and control costs has also helped farmers solve the problem of labor shortage, laying a solid foundation for high grain yield and harvest.In recent years, Sinan County has always implemented the strategy of “storing grain in the ground and storing grain in technology” throughout the entire process of standardized rice planting, vigorously promoting scientific and technological planting methods such as mechanical transplanting, drone management, and mechanized harvesting, further promoting the intelligence, mechanization, simplification, and efficiency of rice production, and inserting “technological wings” into grain production, allowing the masses to hold their rice bowls more stable, Let the path of rural revitalization go deeper and wider.
