In Table 3, the droplets deposition distribution of the round shape crown was compared with that of the open
shape with a working height of 1.0 m.
The CV is often used as an indicator of droplet deposition distribution uniformity and the variance of mean value was analyzed.
There are statistically significant differences in the droplet deposition density between the upper, middle and lower layers of the round shape canopy at 5% level conditions, but there was no obvious difference of droplet deposition density between the upper and middle layers of open shaped trees under 5% level conditions
