摘　　要：为研究不同除草剂对小麦田禾本科杂草的防治效果,以喷施清水为对照(CK),设置4种药剂进行试验,评价药剂的安全性、防效和小麦产量。结果表明,4种药剂在设计剂量范围内对小麦均较安全,药后15 d,4种药剂对小麦田禾本科杂草的防除效果均在65%。药后30 d,4种药剂对小麦田禾本科杂草的防除效果均在80%,其中以5%唑啉·炔草酯乳油80 mL/667 m2的效果最好,药后15 d和药后30 d的防效分别为90.49%和93.51%;其次是30 g/L甲基二磺隆可分散油悬浮30 mL/667 m2,药后15 d和药后30 d的防效分别为86.39%和91.26%。因此,可使用5%唑啉·炔草酯乳油80 mL/667 m2和30 g/L甲基二磺隆可分散油悬浮30 mL/667 m2对小麦田杂草进行防治,为避免抗药性发生进行交替轮换使用。In order to study the control effect of different herbicides on gramineous weed in wheat field,four insecticides were used to evaluate the safety,control effect and wheat yield.The results showed that all the four agents were safe for wheat within the designed dose range.The control effect of the four agents on weeds in wheat field was above 65%at 15 d after administration,and above 80%at 30 d after administration.Among them,5%zoline and acetylide emulsion 80 mL/667 m2 had the best effect,and the control effect of 15 and 30 days after treatment were 90.49%and 93.51%,respectively.Followed by 30 g/L methyldisulsulfuron dispersed oil suspension 30 mL/667 m2,15 days after the drug and 30 days after the drug control effect of 86.39%and 91.26%,respectively.Therefore,the use of 5%zoline and acetylide emulsifiable oil 80 mL/667 m2 and 30 g/L methyldisulon dispersive oil suspended 30 mL/667 m2 for weed control in wheat fields can be alternated to avoid the occurrence of resistance.
