摘　　要：通过在不同时期对燕麦田进行同样除草剂组合处理,或者同一时期不同除草剂组合处理,测定其田间草害发生情况和产量情况,对比各处理的杂草防治效果。结果表明,处理1和处理2(异丙甲草胺、二甲戊灵辛酰溴苯腈组合)、处理3和处理4(丙草胺、吡嘧磺隆辛酰溴苯腈组合)、处理9和处理10(五氟磺草胺、吡嘧磺隆溴苯腈组合)在燕麦苗齐之前和燕麦出苗以后禾本科杂草2叶1心之前田间喷雾,以及处理7(氟乐灵、吡嘧磺隆溴苯腈组合)在燕麦出苗以后禾本科杂草2叶1心之前田间喷雾对禾本科杂草和非禾本科杂草均能起到显著的防治效果,其产量结果均高于人工除草对照,适合燕麦田间草害防治应用。Weed control efficiency of every treat was contaasted by same herbicide group treating oat field indifferent times or different herbicide group at same time,measuring their occurrence of field weed and the yield situation of oat.The results showed that the first treating time of treat1and treat2(metolachlor、pendimethalin、bromoxynil octanoate group)、treat3and treat4(pretilachlor、pyrazosulfuron-ethyl、bromoxynil octanoate group)、treat9and treat10(penoxsulam、pyrazosulfuron-ethyl、bromoxynil group)mist spraying respectively before the oat seedling emerging entirely or after oat seedling before gramineous weed2leaves1heart,and the first treating time of treat7(treflan、pyrazosulfuron-ethyl、bromoxynil group)mist spraying after oat seeding and before the gramineous weed2leaves1heart,the prominent control efficiency were received.
