摘　　要：为筛选南方亚麻最佳除草剂,以乙草胺、金都乐、二甲四氯钠、烯草酮4种除草剂为材料进行了杂草防效及对亚麻生长影响的比较研究。结果表明,乙草胺及其与二甲四氯钠、烯草酮的组配处理杂草防效最佳,株防效平均达85.17%以上,鲜重防效达79.73%,但该组处理有明显药害,出苗率为50.00%左右,原茎产量减少43.70%以上,不建议在生产上使用;金都乐及其与二甲四氯钠、烯草酮的组配处理杂草防效较好,株防效平均达75.40%,鲜重防效达66.39%,且能促进亚麻种子发芽,提高出苗率,增加原茎产量,增幅达25.93%以上;以金都乐+二甲四氯钠处理效果表现较理想,可在大田生产中推广应用。In order to screen the best herbicide,comparative study of weed control effect and growth were conducted with Acetochlor,Metolachlor,etc.4 herbicides as material.The results showed that there was the best weed control effect between Acetochlor and its group treatment with MCPA,Clethodim,their plant control effect was over an average of 85.17% and fresh weight control effect of 79.73%,but the group teratment had significant injury,their emergence rate was only 50.00%,and stem yield reducted more than 43.70%.Therefore,the group teratment was not recommended for use in production;Metolachlor and its group treatment with MCPA,Clethodim had good weed control efficacy,their plant control effect was over an average of 75.04% and fresh weight control effect of 66.39%,and which could promote seed germination,improve the germination rate and enhance stem yield,an increase of 25.93% over.The weed control effect of the group treatment between Metolachlor and MCPA was better performance,which could be widely applied in the field production.
