Unmanned Science and Technology: Injecting New Vitality into Northeast Economic DevelopmentUAV 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.1.
