摘　　要：本文概述了9种除草剂对南方亚麻田杂草的田间防治效果,通过田间试验表明,二甲四氯钠、敌草胺、异丙甲草胺、精异丙甲草胺4种除草剂对亚麻田杂草的防除效果理想,速效株防效分别为82.05%,79.49%,82.05%,82.05%;5个月后的株防效在68%以上,鲜重防效在41%以上,且对亚麻无药害,药剂持效期长达半年,可在南方亚麻田杂草防除中推广应用。This paper summerizes the field control effects of nine herbicide to southern flax field weeds, The field experiment shows that MCPA-Na, Napropamide, Mctolachlor and s-meto- lachlor have ideal effect on weeds in south flax field.The quick control efficiency respectively are 82.05%, 79.49%, 82.05%, 82.05%; five months later, the plant control efficiency is more than 68%, the fresh weight control efficiency is more than 41%. For their long residual activity and safety to flax, these four herbicides can be applicated in south flax field.
