摘　　要：静电喷雾技术是农业病虫害防治的一种新兴技术,在国内也引起人们越来越多的关注。静电喷雾技术的关键就是使喷出的雾滴带电,研究内容主要包括液体的雾化、雾滴的运动和沉降3部分。液体静电雾化技术是液体在风送式、液力式或离心式3种雾化方式的基础上,使雾滴带电后进一步雾化。雾滴的运动要影响到雾滴的扩散,不同的喷雾环境(如电场、风速、温度和湿度)都会影响其沉降状态和分布的均匀性。雾滴沉降分布的好坏会直接影响到静电喷雾技术的应用领域和前景。Electrostatic spray technology is a new agricultural pest control technology and it has drawn increasing attention in China. The key of electrostatic spray technology is to eject the droplet charged, its research mainly includes three parts, liquid atomization, droplet movement and settlement. Electrostatic atomization of liquid is a liquid delivery on the basis of three types, the wind type, hydraulic type and centrifugal atomization method, so that after the further atomization of charged droplets. Droplet ~s movement influence the spread of droplet, different spray enviromnent, such as electric field, wind speed, temperature and humidity will affect their state and settlement of the uniformity. The quality of the distribution of droplet deposition will affect the electrostatic spray technology, applications and prospects directly.
