Plant protection drones to serve agriculture have developed rapidly in developed countries such as Japan and the United States. In 1990, Japan's Yamaha Corporation took the lead in launching the world's first drone, which is mainly used for spraying pesticides. The first application of pesticide spraying in rice growing areas in southern my country. In 2016, agricultural plant protection drones have gradually become the new favorite of the industry, and there have been cases of using drones for plant protection in various places. According to the latest statistics from the Ministry of Agriculture, as of June 5, 2016, there are more than 300 companies producing professional drones in my country, of which more than 200 are plant protection drone manufacturers, producing a total of 178 plant protection drones. There are more than 5,000 aircrafts in total.
According to statistics, in 2018, the number of plant protection drones in the market has exceeded 30,000, and the total area of flying defense operations has exceeded 300 million mu. This also indicates that the development of China's aviation plant protection industry has entered a new era.
A remote-controlled agricultural spraying small aircraft, petite and powerful, can load 8-10 kilograms of pesticides, spray pesticides at low altitudes, and complete operations on one mu of land per minute. Its spraying efficiency is 30 times that of traditional labor. The aircraft adopts intelligent control, and the operator controls it through the ground remote control and GPS positioning. The downward airflow generated by the rotor helps to increase the penetration of the fog flow to the crop, and the control effect is good. At the same time, it can be controlled remotely. Greatly improve the safety of pesticide spraying. It can also carry out real-time monitoring of agricultural diseases and insect pests by carrying video devices.
The small unmanned helicopter has a low operating height, less drift, and can hover in the air without a special take-off and landing airport. The downward airflow generated by the rotor helps to increase the penetration of the fog flow to the crop, and the control effect is high. Operation, spraying operators avoid the danger of exposure to pesticides and improve the safety of spraying operations and many other advantages. In addition, the spraying method of electric unmanned helicopters can save at least 50% of pesticide usage and 90% of water consumption, which will greatly reduce resource costs. The method of spraying with drones greatly reduces the risk of contact caused by gathering of people.
Advantages of agricultural drones：
Compared with oil-powered drones, electric drones have a small overall size, light weight, lower depreciation rate, low labor cost per unit operation, and easy maintenance.
In addition to learning to operate plant protection drones, to provide plant protection flying defense services, master the corresponding knowledge of agriculture, pesticides and plant protection. Different crops have different application amounts of chemical solutions, different concentration requirements, and accuracy of machine performance. Requirements.
