The arriving type nozzle and the diffusing type nozzle are used for Horizontal boom of the motor sprayer.
We studied on the comparison between these two nozzles and spraying methods of the nozzles by the effective depositted ratios (=depositted chemicals to leaf and stem/chemicals to field surface) diameters, and densities of agricultural chemicals on rice leaf, used on statistical method.
At the results, the diffusing type nozzle was better than arriving type nozzle to chemical spraying at paddy field in this case, but the arriving type nozzle is good idea at arriving tendency of chemical particles.
