The domestic plant protection industry has started, but currently there are no clear industry standards in the industry, including UAV’s own technology, performance standards, plant protection standards, etc. For our country, the application of plant protection machine spraying pesticide not only has great economic value, and has social value: agricultural plant protection machine not only ultra-high work efficiency, and will not pose a threat to people’s life safety. At the same time can save a lot of labor and agricultural input costs, and finally increase the economic benefits of farmers.
I. Definition and classification of plant protection UAVs
Plant protection UAV is a kind of UAV used for agriculture and forestry plant protection. The UAV consists of a flight platform (fixed-wing, helicopter, multi-axis aircraft), navigation flight control and spraying mechanism. It can be sprayed with chemicals, seeds, powders, etc. Flight control by ground remote control or navigation.
The development of UAVs in China started relatively late, but the development is rapid. At present, there are two kinds of plant protection UAVs sold in China: oil-powered UAVs and electric UAVs.
Ii. Development policy of plant protection UAV industry
The UAV plant protection operation has the characteristics of precision, high efficiency, environmental protection, intelligence and simple operation. In addition, due to its small size, light weight, convenient transportation, and flexible flight control, plant protection UAVs have good applicability for different plots and crops. Therefore, in recent years, the state has introduced many policies to support the development of agricultural, forestry and plant protection drones.
Advantages of UAV plant protection
Plant protection drones are safer than traditional spraying techniques.
Agricultural UAVs can be used for low-altitude agricultural monitoring, plant protection, and assisted pollination in crop seed production. Pesticide spraying is the most widely used method in plant protection. Plant protection drones with cameras can fly multiple times to patrol fields and help farmers get a more accurate picture of grain growth so they can better target pesticide spraying, pest control or weed removal. Its efficiency is 100 times faster than manual spraying, but also can avoid the poisoning risk of manual spraying.
Compared with traditional spraying technology, the operation is more efficient.
The rotor of the pesticide spraying plant protection UAV generates downward airflow, which disturbs the crop leaves, and the liquid medicine is easier to penetrate, which can reduce the pesticide dosage by more than 20% and achieve the best spraying effect. The ideal flying height is less than 3m, and the flying speed is less than 10m/s, which greatly improves the working efficiency and realizes the insecticidal effect more effectively. However, the traditional spraying technology is slow and inefficient.
Spraying drones are more economical than traditional spraying techniques.
The price of one mu of UAV plant protection and spraying service is only 10 yuan, and it only takes about two or three minutes. Compared with the traditional spraying technology, it saves the cost, manpower and time. The difference between the two is that they can prevent crop disasters in advance, and do not waste resources, spraying evenly, comprehensive coverage, is a good helper of plant protection!
