Overview

Experiments show electrostatic UAV spraying increases droplet deposition on apple trees, highlighting benefits for pest control.

Key Points

  • This research aims to evaluate the impact of electrostatic spray deposition on droplet distribution in apple trees during the blooming stage.
  • Conducted experiments comparing electrostatic and conventional UAV spraying under varying flight heights of 1.0 m, 2.0 m, and 3.0 m.
  • Measured spray deposition on upper, middle, and lower canopy layers using test paper.
  • Assessed droplet number density and size across different leaf surfaces.
  • Electrostatic spraying increased droplet number density by 17.6%.
  • Droplet size was reduced by 25.3% with electrostatic force compared to conventional spraying.
  • Improved spray performance aids pollination and pest control during apple trees' early growth stage.
