摘　　要：为筛选藜麦田禾本科可使用的杂草,本试验采用随机区组设计,研究了精草通克、烯草酮、精稳杀得的建议施用量对藜麦田禾本科杂草的防除效果,以及对藜麦产量的影响。结果表明:精草通克、烯草酮、精稳杀得可以用在藜麦田防除禾本科杂草。精草通克施用量在348 mL·hm^(-2)、烯草酮施用量在450 mL·hm^(-2)对稗草、马唐和牛筋草防效达到100%,精稳杀得施用量在1 050mL·hm^(-2)对稗草、马唐和牛筋草具有较好的防治效果。3种药剂在藜麦田建议施用量为:精草通克237mL·hm^(-2)以上、烯草酮300mL·hm^(-2)以上和精稳杀得1050mL·hm^(-2)以上。3种药剂处理对藜麦产量没有明显不利影响。In order to compare the control effect of different herbicides on gramineae weeds in quinoa field,three kinds of foliar-teeament agents（quizalofop-p-ethyl clethodim fluazifop-p-butyl）were conducted to investigated the gramineae weeds control effects against gramineae weeds in quinoa field.The influence of different concentration of herbicide on quinoa yield.The results showed that three kinds of herbicides could be used in quinoa field control gramineous weeds.Under application amount of quizalofop-p-ethyl was 348 mL·hm^-2 and the application amount of clethodim was 450 mL·hm^-2.The weed control of barnyard grass,common crabgrass and goose grass was 100%.Application amount of fluazifop-p-butyl was 1 050 mL·hm^-2 had better control on barnyard grass,common crabgrass and goose grass.The suggest application amount of quizalofop-p-ethyl was 237 mL·hm^-2,the application amount of clethodim was 300 mL·hm^-2 and the application amount of fluazifop-p-butyl was 1050 mL·hm^-2.Three kinds of medicament on quinoa yield no significant differences.
