How do plant protection drones achieve precise spraying?

For spraying medicine, many farmers have a habit of misunderstanding, that is, the more spray the better, it is best to be able to soak it all like a bath. In fact, doing so not only increases costs and reduces efficiency, but also produces phytotoxicity and pesticide residues, pollutes the environment, and causes soil agglomeration.

For some specific crops and specific agricultural links, more precise application of pesticides is required, such as cotton chemical control and rice weeding. The precise control of the dose in these links is very strict. Heavy spraying and multiple spraying will cause phytotoxicity; missed spraying and less spraying will not achieve the control effect. Both of these affect the output quality and yield of the crop.

The plant protection drone atomizes the high-concentration medicinal liquid to make the medicinal liquid evenly dispersed and attached to the surface of the crop, and the accuracy of the atomization is relatively high. At the same time, different spraying scenarios have different requirements for the size of atomized particles, and traditional pressure nozzles cannot independently and accurately control the flow rate and atomized particles, making it difficult to achieve true accurate spraying.

YJTech UAV is equipped with centrifugal variable atomization spraying system, which opens the era of precise operation of plant protection UAV. The precise spraying effect of agricultural drones is once again improved.
