超低容量喷雾选用喷洒雾滴直径80微米以下雾滴,全是漂移雾滴,从环保考虑,容易造成远距离漂移,在逆温条件下可漂移10公里可造成环境污染和药害,国外发达国家以立法禁止使用低容量喷雾。我国从20世纪70年代开始研究推广,但当时没有生产适合于超低容量的农药剂型,或植保机械,或因气候影响等原因没有发展,仅在森林、草原灭虫有过一定面积的使用。长时间以来我国没有推广超低容量喷雾。高溫干旱时下不宜低容量喷洒多年来主要在北方使用飞机作业,作业季节气候高温干旱严重影响药效。在高温干旱条件下飞机作业喷液量小,雾滴细,飘移挥发损 Ultra-low volume spray spray spray droplet diameter below 80 microns droplets are all drift droplets, from the environmental considerations, likely to cause long-distance drift in the inversion temperature drift of 10 km can cause environmental pollution and injury, developed abroad Countries to legislate against the use of low-volume spray. Since the 1970s, China started to research and popularize it. However, there was no production of pesticide formulations suitable for ultra-low capacity or plant protection machinery, or there was no development due to climatic impacts and other reasons. Only a certain area of ​​pests was used in forests and grasslands. For a long time our country did not promote ultra low volume spray. High temperature and drought nowadays should not be low-capacity spray for many years mainly in the north to use aircraft operations, operating season climate seriously affect the efficacy of high temperature and drought. Under high temperature and drought conditions, the operation of the aircraft jet is small, fine droplets, drifting volatile loss
