一、概况:超低量喷施农药是六十年代发展起来的一项新技术。开始是用飞机在空中进行喷洒,称航空超低量喷雾。地面超低量喷雾是近几年才在生产上应用的,其工效虽不及航空超低量喷雾,但远较普通(高容量)喷雾为高,且机具型小,轻便,灵活,投资少,成本低,便于社队普及和对山地、丘陵及面积较小的地块喷雾。
First, an overview: ultra-low-volume spraying of pesticides was developed in the sixties a new technology. The beginning is to use the aircraft to spray in the air, said the aviation ultra-low volume spray. In recent years, the application of ultra-low-level ground spray has been noticed. Its work efficiency is lower than that of ultra-low-level aerosol spray, but it is much higher than ordinary (high-capacity) spray and is small in size and light in weight. Low cost, easy access to communes and communes and spraying of hills, hills and smaller plots.
