摘要
[目的]通过对比试验,筛选适合本地麦田除草、防除效果好且安全性高的除草剂品种。[方法]设冬季和春季2组试验。采用均匀喷雾法,喷液量525～600 kg/hm2。[结果]总草的株防效和鲜重防效均较好的是5.8%麦喜+50%异丙隆,15%麦极,阔世玛,22.5%溴苯晴乳油+13%二甲四氯钠水剂,20%苯磺隆可湿粉剂+30%苄嘧磺隆+助剂,75%农基麦通灵干悬乳剂+3%世玛,株防效和鲜重防效均在94%以上。所用除草剂安全性好,无药害现象发生。[结论]冬季除草选用麦喜+异丙隆,苯磺隆+苄嘧磺隆+助剂,阔世玛,溴苯晴乳油+二甲四氯钠;春季除草选用大惠农+非常静,麦极,农基麦通灵+世玛。
[Objective]Herbicide varieties which were suitable for the local wheat grass and had better effect and high safety were screened by contrast tests.[Method]Two sets of tests in winter and spring were set up.Experiments were conducted with uniform spray method.Each spray quantity was 525-600 kg per hectare.[Result]The overall control effect of grass plants and fresh weight control effect of 5.8% wheat-HI ＋ 50% isoproturon,15% wheat pole,Sigma Broad,22.5% EC ＋ 13% MCPA,20% tribenuron wettable powder ＋ 30% bensulfuron ＋ additives,75% agricultural Jimai psychic emulsion dry hang ＋ 3% sigma were better,and the fresh weight of control effect were more than 94%.Herbicides used were securie,and had no phytotoxicity.[Conclusion] It was proposed weed control in winter of wheat HI ＋ isoproturon,tribenuron ＋ bensulfuron ＋ additive,Sigma Broad,EC ＋ MCPA sodium,and weed control in spring of Oe ＋ very quiet,wheat pole,agricultural Jimai psychic ＋ world Ma.
