摘　　要：试验结果表明,金都尔等9种除草剂对AD、Diane和yaf155 3个亚麻品种的田间杂草均有一定的防除效果,其中金都尔、二甲四氯钠、敌草胺、金都乐等4种除草剂对亚麻田杂草的防除(株防和鲜防)效果理想,施药后120 d对杂草的株防效在50%～61%之间,鲜重防效在41%～54%之间,且对亚麻无药害。这4种除草剂对3个亚麻品种试验田中杂草的株防效无差异显著性,在鲜重防效上,金都尔和金都乐在不同品种间存在差异性。Experimental results showed that nine herbicides（s-metolachlor,etc.） have certain weed-control effect on three flax varieties（AD,Diane and yaf155）.Among nine herbicides,s-metolachlor,MCPA-Na,napropamide and metolachlor have ideal effect.120 d after spraying these four herbicides,the control efficiency per plant is between 50%～61%,the control efficiency of fresh weight is between 41%～54%,and there is no phytotoxicity to flax.These four herbicides have no significant difference in control efficiency per plant for the three flax varieties,but s-metolachlor and metolachlor have difference in control efficiency of fresh weight among three flax varieties.
