低容量喷雾法:单位面积上在施药量不变的情况下,将农药原液稍加水稀释后喷雾。添加水量相当于常规喷雾技术的1/5~1/10。具体方法是将常规喷雾机具的大孔径喷片换成孔径为0.3 mm的小孔径喷片即可。这样可减少农药流失,节约用水,显著提高防治效果。静电喷雾法:在喷药机具上安装高压静电发生装置,使带电喷施的药液雾滴在作物叶片表面的沉积量大幅增加,农药的有效利用率可 Low-volume spray method: per unit area in the same amount of pesticide application, the pesticide solution diluted with water spray. Add water equivalent to conventional spray technology 1/5 ~ 1/10. The specific method is to replace the conventional large-diameter spray gun spray holes into a small aperture 0.3 mm diameter jet can be. This will reduce the loss of pesticides, water conservation, significantly improve the control effect. Electrostatic spray method: In the spraying equipment to install high-voltage electrostatic generation device, so that the liquid spray droplets on the surface of crop leaf deposition increased significantly, the effective use of pesticides can be
