超低量喷雾及其优缺点超低量喷雾是用于消灭农业病虫害方面的一项新技术。它喷洒的是不经稀释(不加水)的原液或高浓度的油荆药液,施药量很低(每亩喷几十至几百毫升,喷液量约为一般喷雾的(1/50)～(1/500)),工效比一般喷雾机提高五倍至十几倍以上。这种喷雾机大大节省了人力物力,降低了作业成本,同时有利于及时抓住防治时机,对于缺水地区,更具有特殊意义。超低量喷雾的雾滴直径极小(约为一般喷雾的十分之一),且具有一定粘度,能均匀地覆盖在作物表面上,不怕日晒及雨水冲刷,有利于药效的发挥,提高了防治效果。
Ultra low volume spray and its advantages and disadvantages Ultra low volume spray is a new technology for the elimination of agricultural pests and diseases. It is sprayed with undiluted (without water) stock solution or high concentration of liquid Jing, application rate is very low (dozens to hundreds of milliliters spray per acre, spray volume is about the general spray (1/50 ) ~ (1/500)), ergonomics than the general sprayer increased five times to more than ten times. This kind of sprayer greatly saves manpower and material resources, reduces the operating cost, and at the same time helps to seize the opportunity of prevention and control in time, and has special significance to the water shortage area. Ultra-low-volume spray droplets diameter is very small (about one-tenth of the general spray), and has a certain viscosity, can be evenly covered in the crop surface, not afraid of the sun and rain erosion, is conducive to the efficacy of play, Improve the control effect.
