摘　　要：研究了不同类型乳化剂及其用量对乙草胺微胶囊成囊性能的影响。通过光学摄影显微镜、激光粒度仪对微胶囊表面形貌、粒径大小及其分布进行了表征。结果表明:采用苯乙烯马来酸酐共聚物(SMA)作为乳化剂,当用量3%时能够得到囊形较好的乙草胺微胶囊。二甲苯的加入有利于微胶囊的形成。The effects of different emulsifier and amount on the microcapsule properties of acetochlor microcapsules were studied. The morphology and size distribution of the microcapsules were investigated by the microscope and laser particle sizer. The results showed that the mass weights of styrene maleic anhydride （SMA） as emulsifier were 3%,microcap sules with good shape could be prepared. Microcapsule can be accelerated by adding organic solvent.
