| 摘 要： | 田间测定了氯·乙·莠对玉米的安全性及其除草效果,结果表明,40%氯·乙·莠可湿性粉剂3375～3750g/hm2防除玉米田禾本科杂草稗草、狗尾草、马唐效果较好,株防效为74.4%～99.2%;对阔叶杂草中的反枝苋也有很好的效果,株防效为91.4%～100%。在推荐剂量下,氯·乙·莠防除玉米田杂草对玉米安全,且有显著的增产作用,比空白对照增产9.9%～16.2%。

| Abstract: | Safety to maize and weed control effect were tested with chlorotoluron+acetochlor+atrazine 40% WP in field .The result showed that the weeds such as Echinochloa crusgalli(L.) Beauv,Setaria viridis(L.)Beauv,Digitaria sanguinalis(L.) Scop could be effectively controlled by chlorotoluron+acetochlor+atrazine at the dosage of 1 350～1 500g.a.i/hm~2, the effect of weed control was 74.4%～(99.2%).Amaranthus retroflxus L. also could be effectively controlled. The effect was 91.4%～100%. Chlorotoluron+acetochlor+atrazine was safe to maize at all rates tested, and the yields were increased (9.9%)～16.2% than CK. |
