摘　　要：田埂杂草对农业生产会产生不利影响,为安全有效解除其影响,试验不同除草剂对蛇床[Cnidium monnieri(L.)Cuss.]和灰绿藜(Chenopodium glaucum L.)的防除效果。结果表明,50%丙草胺SC 80 mL/667 m^2+7.5%精噁唑禾草灵SC 100 mL/667 m^2+20%双氟·氟氯酯WG 6 g/667 m^2效果最好,对蛇床和灰绿藜的校正株防效分别高达93.1%、94.3%;鲜质量防效分别达到99.1%、98.7%。Weeds growing on the ridge of the field have adverse effects on agricultural production.With the purpose of eliminating the harmful effects of the weeds effectively and safely,the current research determined the efficacy of different herbicides in controlling Cnidium monnieri(L.)Cuss and Chenopodium glaucum L.,which grow on the ridge of the wheat field.Among different treatments,the treatment with 50%propisochlor SC applied at 80 mL/667 m^2 plus 7.5%fenoxaprop-p-p-ethyl SC at 100 mL/667 m^2 plus 20%difluoro-chloromethyl WG at 6 g/667 m^2 was demonstrated to be most effective in controlling the two weeds.Its efficacy based on modified weed plant number against Cnidium monnieri(L.)Cuss and Chenopodium glaucum was 93.1%and 94.3%,respectively;its efficacy based on weed fresh weight against Cnidium monnieri(L.)Cuss and Chenopodium glaucum reached 99.1%and 98.7%,respectively.
