Currently, Due to the impact of factors such as crop plant height on agricultural production, it is difficult to use large and heavy machinery to conduct farmland irrigation and pesticide spraying. On top of that, the manual operation has high labor intensity and long operation time. When carrying out farmland irrigation and pesticide spraying manually, overly irrigation and unevenly pesticide spraying will happen. This will not meet the results of high yield and stable production but will reduce the utilization efficiency of water and pesticide. Due to the advantages of high efficiency and speed, simple operation, drones have gradually become a new type of tool for agricultural production, especially in pesticide spraying. In agricultural production, the wide applications of agricultural drones for sale not only avoid the damage of large and heavy machinery to crops, but they also can ensure the crops yield, and solve the difficult problems in agricultural mechanization, widely preferred by farmers.
Due to advantages such as small mass, good maneuverability, flexible flight speed and spraying height, drones can be well used in pesticide spraying operations in complex terrain. Spraying pesticides by the fertilizer spraying drone can help to spray pesticides evenly and reduce the waste on pesticides and water resources. Compared with regular manual operations, it ensures not only the safety of operators but also the amount of pesticide sprayed properly. Largely improved the efficiency of pesticide spraying. In addition, drones have a relatively low operating height which makes pesticides spraying less affected by wind, largely reduces environmental pollution by pesticides, and it has very good environmental protection characteristics.
Agricultural drones mostly have spiral wings. When spraying pesticides, due to the impact of working principles and low height operations, blades rotation could shake the crops, then, pesticides could be sprayed on the back of the stems and leaves evenly in order to kill pests. Using drones to spray pesticides could not just to boost the coverage density of the sprayed liquid per unit area and spraying uniformity. It could also reduce pesticide loss to a certain degree, it is something that impossible to achieve with manual and other spraying equipment currently. Compared with traditional pesticide spraying methods, spraying pesticides by drones has quite obvious results on pest control.
