The droplet coverage rates showed no significant difference between the left, middle, and right parts of the plant crown. For the droplet coverage rate of the open center shape canopy, there are no significant differences between the front,
middle and rear directions, but the left and middle parts had significant differences, and the middle part had the
highest value, which was 5.27%.
The droplet coverage rate has a low level and large discrete degree.
For these two shapes, there were no obvious differences on the droplet density and diameter in the front, middle and rear
part plants, but the differences of the droplet deposition density between the left, middle and right part reached a 0.5% significant level
