UAV has become an indispensable scientific and technological force in modern society. In agriculture, as an important agricultural producing area in China, the application prospect of UAV is broad. It can carry out accurate pesticide spraying and crop growth monitoring. For example, in a large paddy field in Northeast China, drones can spray pesticides evenly according to the set route. Compared with traditional manual spraying, it is not only more efficient, but also can reduce pesticide waste and improve the quality of agricultural products. According to the statistics of agricultural departments, using drones for plant protection operations can improve the efficiency by 5-10 times compared with traditional methods. In the field of geographic mapping, UAV can quickly obtain detailed data of complex terrain in Northeast China, and provide accurate maps and data support for urban planning, resource exploration and other work.Northeast China is facing the problem of population loss in recent years. Although the labor cost has been relatively reduced, the shortage of labor still exists in some industries. The application of unmanned technology can make up for the shortage of manpower to some extent. For example, in some remote forest areas or mining areas, drones can carry out security patrols, environmental monitoring and other work to reduce dependence on manpower. Unmanned shops and banks can be laid out in towns with relatively small population and provide basic commercial and financial services without a lot of human support.The climate in Northeast China is cold, and the terrain in some areas is complex. For example, the battery life of drones decreases in a low temperature environment, and the sensors of unmanned vehicles may fail in ice and snow weather. In view of these problems, scientific and technological enterprises need to intensify research and development to develop unmanned scientific and technological products that adapt to the special environment in Northeast China. The applicability of unmanned technology products in Northeast China can be improved through the research and development of cold-resistant battery technology and the design of ice and snow protection for sensors.
