喷雾

Air-assisted electrostatic spraying technology is a spray technology which integrated the advantages of air-assisted hydraulic spraying technology and electrostatic spraying technology. It not only atomize the droplet again, but also reduce the droplet drift, increase the deposition and adhesion performance of pesticide in the plant leaves. It can increase the efficiency of chemical using, reduce the pesticide"s waste and environment pollution, make the full use of resource and reduce the cost of production. It can also increase the agriculture sustainable development and reduce the chemical"s threat to the environment.
