| Abstract: | Electrostatic spraying technique is an advanced technique of modern agriculture. Compared to normal pesticide spraying, it shows better improvements in droplets deposition, uniform distribution and pesticide utilization. It ′s an important method to realize the aim of saving energy, decreasing pesticide, cutting cost and improving effectiveness for the sustainable development of future agriculture. This paper introduces the development of crop protection electrostatic spraying technique in detail. The basic electric theories, merits and drawbacks of three kinds of charging means are introduced and analyzed comparatively. The research progress of charging and atomization of liquid pesticides, movement of charged droplets, charged droplets ′ interactive deposition on the targets at home and board is reviewed. Various electrostatic spraying products and protypes are also introduced. Meanwhile, the paper carries a depth analysis of the existing problems in electrostatic research and application, discusses the urgent problems and feasible application modes of electrostatic spraying technique, hoping to provide reference for the subsequent investigation and application. |
