Using the EAVISION E-A10 Agricultural Drone, the parameters were set as: speed 1 m/s, height 1.2 m, spray width 2 m, dosage per mu 4.5 L, and droplet size 30 μm.
Through observation during the application process, in the middle and late stages of tobacco growth, the drone wind field did not cause damage to the tobacco leaves.
The droplet density and deposition distribution uniformity on the tobacco leaves were very good, and the backs of the tobacco leaves all showed deposition; the EAVISION drone's terrain-following flight height is critical to the amount of chemical deposition on the tobacco leaf surface.
