高功效低容量静电施药装置及其应用

High-efficiency and Low-capacity Electrostatic Spraying Device and Its Application

高功效低容量施药装置是一种以高压静电驱动,运用碳纤维材料制成可伸缩喷杆的便携农药喷雾器。该装置通过静电喷雾技术能够实现精准施药和定向沉积。高功效低容量静电施药装置喷雾雾滴直径约100μm,喷杆最大展幅超过5 m,作业效率提高5倍。喷液量120 L/hm^(2)防治水稻稻纵卷叶螟,在药后7 d和药后14 d,对稻纵卷叶螟的防治效果分别为89.98%和86.42%。该装置通过提高农药利用率,表现出卓越的省工省药、节水增效性能,可有效解决小规模农业合作组织和分散农户打药困难的问题,满足高秆作物以及丘陵、山地作物的病虫害防治需求。

The high-efficiency and low-capacity spraying device is a portable pesticide sprayer powered by high-voltage static electricity with a telescopic bar made of carbon fiber material.It can achieve precise spraying and directional deposition through electrostatic spraying technology.The spray droplet diameter of high-efficiency and low-capacity electrostatic spraying device is about 100μm,the maximum extension of the spray bar exceeds 5 m,and the operation efficiency increased by 5 times.The control effect of spraying 120 L/hm^(2) on rice leaf roller was 89.98%and 86.42%at 7 d and 14 d after treatment,respectively.Through improving the utilization rate of pesticide,the device shows excellent performance in saving labor and drugs,saving water and increasing efficiency.It can effectively solve the problems in spraying pesticides of small-scale agricultural cooperative organizations and scattered farmers,and meet the needs of disease and pest control for high-stalk crops as well as crops in hilly and mountain areas.
