On May 20, in the vegetable base of Maoyuan Guangfa in Guangjitun Village, Yanqing District, a plant protection drone moved slowly above the vegetable field of 100 mu, shuttled back and forth along the vegetable field with precision, and sprayed the atomized medicine. The liquid is evenly spread on the vegetables, and the whole process is fast and efficient. This is a demonstration test activity of plant protection drones jointly organized by the two-level plant protection station in Beijing and Yanqing District and the Maoyuan Guangfa Vegetable Base in Yanqing District.

        The intelligent plant protection insect control drone replaces manual spraying of drugs, realizes "machines for humans", saves time, labor and labor, greatly improves work efficiency, and allows farmers to easily enjoy the convenience brought by technological development. Han Yongmao, the head of Beijing Maoyuan Guangfa Planting Professional Cooperative, said: "In the past, all pesticides were done manually, and each person could only complete a maximum of 3 mu of vegetables per day. After the drone is on duty, it only takes 2 minutes to spray each mu of land. It only costs ten yuan, which saves time and money.”

        The maximum charge of the drone can reach 20 kilograms, the spray width of the vegetable spraying drone can reach 5 meters, and the operation efficiency of a single sortie can reach 10 acres. In addition, the downward airflow generated by the rotor of the drone can also disturb the leaves of animals, so that the pests on the back of the leaves can also be controlled, which not only improves the spraying effect, but also frees up the labor force and avoids the torment of the farmers from fumigation and sun exposure.

        Carrying out the drone for insect control flight control operation can not only solve the problems of low pesticide utilization rate, poor control effect, and difficulty in outdoor high-temperature spraying operations by conventional spraying methods, but also effectively promote the large-scale unified control of vegetable pests and diseases, relying on agricultural service organizations, etc. The professional team carried out scientific dispensing, spraying, and field prevention and control, which effectively solved a series of problems such as unscientific drug use, low spraying efficiency, insufficient labor force, and high labor consumption of small and scattered farmers, and effectively guaranteed the quality and safety of vegetables.
