摘　　要：以淀粉和乙烯-醋酸乙烯共聚物(EVA)为原料,采用螺杆挤出工艺,制备一种可生物降解的淀粉/EVA复合基材,用作除草剂3,7-二氯喹啉-8-羧酸的控制释放。以此制得的10%二氯喹啉酸缓释剂具有较强的除草活性,有明显的缓释作用,持效期(室内)可达30d,且对水稻安全。The EVA and starch were extruded by extruser and the controlled-release matrix of quinclorac was prepared. The quinclorac controlled-release formulation containing 10% quinclorac was obtained and it would release the active agent in a reasonable amount,by the processes of hydrolysis and/or bio-degradation. The CRF of 10% quinclorac is safe to paddy rice and has the strong weeding activeness with the obvious slow-release function,and its bioactive would last for at least 30 days （in viro）.
