文摘Centrifugal atomization technique is internationally recognized as one of the most appropriate methods for obtaining uniform fine droplets, and also an advanced technology to get a narrower range of droplet particle spectrum. The importance and related mechanism of centrifugal atomization technique in the field of plant protection are expounded, and the overview of centrifugal atomization technique at home and abroad is introduced.
