摘　　要：为明确35%丁噁乳油对夏花生田杂草的防除效果及对花生的安全性和增产效应,采用土壤封闭喷雾法进行了田间试验研究。结果表明,35%丁噁乳油850.0～1312.5 g.a.i /hm2对花生田牛筋草、马唐草、稗草、狗尾草等一年生禾本科杂草及阔叶草苋、马齿苋有较好的防除效果。药后40d,总株防效为85.34%～93.51%,鲜重防效为95.93%～97.76%；对花生安全性较好,增产率为2.53%。A field trial was conducted to evaluate the effects of 35% Butachlor＋Oxadiazon E.C. with soil closed spray application method on weeds control in summer peanut field, peanut security and yield increase.The results showed that 35% Butachlor＋Oxadiazon EC had good effect on control of weeds including annual gramineous weeds, such as Eleusine indica , Digitaria sanguinalis , Echinoch-loa crusgalli , Setaria viridis etc.and broadleaf weeds, such as Grass amaranth , Portulaca oleracea , at a dosage of 3000～3750mL/hm2 in peanut field.The plant control effect was between 85.34% and 93.51%, while fresh weight control effect was 95.93%～97.76% after treatment for 40 days.It was safe to peanut growth and could increase yield by 23.06%～26.17%.
