VARIABLE TOPDRESSING DEVICE BASED ON SIX-ROTOR MULTISPECTRAL UNMANNED AERIAL VEHICLE AND USE METHOD THEREFOR

WIPO Patent Application WO/2024/077668

A1

The present invention relates to the technical field of unmanned aerial vehicles. Disclosed are a variable topdressing device based on a six-rotor multispectral unmanned aerial vehicle and a use method therefor. The device comprises: an unmanned aerial vehicle and a topdressing tank, wherein the unmanned aerial vehicle is provided with a multispectral sensor; the topdressing tank is fixedly connected to the unmanned aerial vehicle, and the multispectral sensor is fixedly connected to the unmanned aerial vehicle; and a port of the multispectral sensor is electrically connected to the unmanned aerial vehicle. The variable topdressing device is guided and controlled on the basis of crop growth monitoring and real-time nutrition diagnosis based on remote sensing data of the unmanned aerial vehicle, so that real-time online variable topdressing is realized; human labor consumed in a topdressing process is reduced, and the fertilization operation efficiency is improved; and intelligent, real-time and precise fertilization is realized according to a required fertilizer amount.
