摘　　要：为探索湖北地区油菜田杂草防除技术,以吡草胺悬浮剂和乙草胺水乳剂为试验药剂,以乙草胺为对照药剂进行了对比试验。结果表明,吡草胺悬浮剂对油菜田网草、看麦娘和牛繁缕都有较好的防效;乙草胺水乳剂对网草和看麦娘的防效较好,但对牛繁缕防效较差;两种药剂的防效均显著优于人工除草,且提高了油菜的安全性,增产效果极其显著。500 g·L^-1 metazachlor suspension concentrate and 500 g·L^-1 acetochlor emulsion in water were conducted to investigate the effects of weed control in rape field of Hubei province. 50% acetochlor EC was used as control. The results showed that 500 g·L^-1 metazachlor suspension concentrate had good effects on controlling Alopecurus aequalis, Beckmannia erucaeformis Host and Malachium aquaticum （L.）Fries. 500g· L^-1 acetoehlor emulsion in water also had good effects on eontrolling Alopecurus aequalis and Beckmannia erucaeformis Host, while it had no effect on Malachium aquaticum （L. ）Fries. The effects of both two reagents were better than manual control. There were good security and prominent effects of yield enhancing.
