The object of this paper is to study the range of pesticide droplet deposit and droplet distribution, in different target district and plant target. By axial-flow fan of the air-carried blast sprayer in greenhouse, spraying experiment was carried out with variable height of nozzle and charged voltage, under the same condition of spray pressure, spray flux and frequency of fan. Taken the barbette model pressure atomization axial-flow air-carried high-voltage electrostatic spraying system as the experiment platform, the parameters of spraying deposition on target were calculated and analyzed. The results showed that one deposition peak area is found along the wind cylinder axes at the distance of 150～200 cm from nozzle; with the increasing voltage, pesticide droplet deposition on plant target increases obviously. The toward-target deposition ratio rises distinctly within range of spraying in the state of induction charge. To adjust height of nozzle and charged voltage is the important measures for adding toward-target deposition depending on the practical target of spraying application.
