摘  要：
本文开展了唑啉草酯等7种除草剂对胡麻田裸燕麦、皮燕麦的防除试验研究,结果表明,在胡麻株高5~7cm,裸燕麦、皮燕麦3~5叶期施药,50g/L唑啉草酯乳油、108g/L高效氟吡甲禾灵乳油、15%精吡氟禾草灵乳油、240g/L烯草酮乳油和10%精喹禾灵乳油有效成分剂量分别为90、145.8、315、432和90g/hm2时,药后45d对裸燕麦的株防效达95.39%以上,鲜重防效达97.21%以上,胡麻增产率在82.79%以上;50g/L唑啉草酯乳油、108g/L高效氟吡甲禾灵乳油、15%精吡氟禾草灵乳油、15%炔草酯可湿性粉剂、10%精喹禾灵乳油和12.5%烯禾啶乳油有效成分剂量分别为90、145.8、270、135、90和412.5g/hm2时,药后45d对皮燕麦的株防效在94.66%以上,鲜重防效达96.13%以上,胡麻增产率在80.25%以上,各药在上述剂量下防治裸燕麦和皮燕麦后均对胡麻表现安全,可大面积示范推广。

摘  要：
Field trial was conducted in linseed field to evaluate control effects of seven kinds of herbicides on Avena nuda and A.sativa.The results showed that using the herbicides when the plant height of linseed was 5-7 cm,Avena nuda and A.sativa was 3-5 leaf stage,and effective dosages of 50 g/L pinoxaden EC,108 g/L haloxyfop-P-methyl EC,15% fluazifop-P-butyl EC,240 g/L clethodim EC and 10% quizalofop-P-ethyl EC were 90,145.8,315,432 and 90 g/hm2,respectively,the plant and fresh weight control efficacies were more than95.39% and 97.21%,respectively,on A.nudain linseed field after 45 days treatment,and the yield of linseed increased more than 82.79%.When effective dosages of 50 g/L pinoxaden EC,108 g/L haloxyfop-P-methyl EC,15%fluazifop-P-butyl EC,15%clodinafop-propargyl WP,10% quizalofop-P-ethyl EC and12.5%sethoxydim EC were 90,145.8,270,135,90 and 412.5 g/hm2,respectively,the plant and fresh weight control efficacies were more than 94.66% and96.13%,respectively,on A.sativain linseed field after 45 days treatment,and the yield of linseed increased more than80.25%.These herbicides were safe to linseed at the recommended dosages,which should be demonstrated and extended in linseed field.
