目前,用机械喷洒农药在植物保护中还占相当大的比重,但是用常规的喷药方法,大部分农药没有能够被利用发挥其效用,而是流失了。据估计,目前用机械常规法喷药,农药的利用率只有20%,这既浪费了很多农药、人力,又造成了污染。如何使喷洒的农药发挥其最高的效能,使大部以至全部的药物都能喷到植物上,并且均匀和牢固地吸附在植物的表面 At present, the mechanical spraying of pesticides also accounts for a considerable proportion of the plant protection, but most of the pesticides can not be used for their effectiveness but are lost by the conventional spraying method. It is estimated that the current routine use of mechanical spraying, pesticide utilization rate of only 20%, which is a waste of a lot of pesticides, manpower, but also caused pollution. How to make spraying pesticides to maximize their performance, so that most of the entire drug can be sprayed onto plants, and uniform and firm adsorption on the surface of plants
