摘　　要：为降低农药使用量,减少农药造成的环境危害,采用^(60)Coγ射线辐射合成了淀粉基农药缓释材料及不含淀粉的聚合物,研究了它们的旋转黏度、可降解性及淀粉基农药缓释材料对吡蚜酮的缓释效果。淀粉基农药缓释材料的可降解性优于不含淀粉的聚合物,其负载吡蚜酮的缓释效果优于凹凸棒土、马铃薯淀粉。5 min时,空白、凹凸棒土、淀粉和淀粉基农药缓释材料负载吡蚜酮的释放百分率分别为大于90%、大于50%和10%~20%;20 min时,空白、凹凸棒土、淀粉和淀粉基农药缓释材料负载吡蚜酮的释放百分率分别为99%以上、大于85%和51%~62%。In order to reduce the use of pesticide and the environmental damage of pesticide,starch-based pesticide sustainedrelease materials and starch-free polymers were synthesized by ^(60)Coγ-ray irradiation.The rotational viscosity,degradability and the sustained-release effects of pymetrozine were studied.The degradability of starch-based material is better than that of starchfree polymers and the pymetrozine sustained-release effect is better than that of attapulgite and starch constrast.At 5 minutes,the pymetrozine release percentage of blank sample was more than 90%,that of attapulgite or starch constrast was more than 50%,and that of starch-based materials was in the range of 10%~20%.At 20 minutes,the pymetrozine release percentage of blank sample was more than 99%,that of attapulgite or starch constrast were more than 85%,and that of starch-based materials was 51%~62%.
