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
