Among them, Z direction wind speed mainly investigates the damage situation of rice plant, and the smaller the wind speed is, the better.

[0026] Further, the Y direction wind field width determined by Y direction wind speed sensor 4 is the test evaluation standard. Because the wind speed of rice canopy is more suitable for pollination when the agricultural unmanned plane assists pollination, 2.5m / s-3.5m / s, therefore, according to the wind speed size collected in this interval, the wind field width under different flight parameters can be judged.
