Abstract:

This experiment addresses the industrial shortcomings of applying plant protection UAV in vineyards, focusing on factors such as flight trajectory, flight altitude, flight speed, and spraying speed. Spraying experiments were conducted in vineyards to optimize the mist coverage rate for aerial pest control operations. The results indicated that flying directly above the grape trellis and flying between two rows of grape trellises did not significantly affect the mist coverage rate, but the latter significantly improved operational efficiency. Flight altitude, flight speed, and spraying speed all had a significant impact on mist coverage rate. The optimal operational parameters include flying in the middle of two rows of grape trellises at a height of 2 meters from the top of the grapes, spraying the two rows of grape trellises below on each pass, with a flight speed of 3 m/s and a spraying speed of 3 L/min.
