摘　　要：为了降低双环磺草酮的用量,节省水稻生产成本,采用盆栽法测定125g a.i./hm^(2)、175g a.i./hm^(2)、225g a.i./hm^(2)和275g a.i./hm^(2)双环磺草酮与25g a.i./hm^(2)吡嘧磺隆混用对稻稗的防治效果及其对水稻的安全性。结果表明:175g a.i./hm^(2)双环磺草酮+25g a.i./hm^(2)吡嘧磺隆、225g a.i./hm^(2)双环磺草酮+25g a.i./hm^(2)吡嘧磺隆对稻稗的株防效显著高于275g a.i./hm^(2)双环磺草酮单剂,且对水稻的安全性较高。由此可见,双环磺草酮与吡嘧磺隆混用能够有效地降低双环磺草酮的用量。To reduce the amount of benzobicyclon and increase the economic benefits of rice fields,by potted test,The efficacy of 125g a.i./hm^(2)、175g a.i./hm^(2)、225g a.i./hm^(2) and 275g a.i./hm^(2) benzobicyclon with 25g a.i./hm^(2) pyrazo⁃sulfuron on ricw grass and the safety of rice.The results showed that 175g a.i./hm^(2) benzobicyclon+25g a.i./hm^(2) pyr⁃azosulfuron and 225ga.i./hm^(2) benzobicyclon+25g a.i./hm^(2) pyrazosulfuron were more effective than 275g a.i./hm^(2) ben⁃zobicyclone and showed high safety for rice.It is seen that the mixing of double cyclicbenzobicyclon and pyrisulfone can effectively reduce the amount of benzobicyclon.
