摘　　要：采用室内和田间小区试验,测定春油菜田旱雀麦(Bromus tectorum L.)对108 g/L高效盖草能EC、5%精喹禾灵EC、240 g/L烯草酮EC 3种常用除草剂的敏感性。室内研究结果表明,旱雀麦对3种除草剂的敏感性大小顺序为5%精喹禾灵EC、240 g/L烯草酮EC、108 g/L高效盖草能EC;田间小区试验表明,108 g/L高效盖草能对旱雀麦的敏感性低于240 g/L烯草酮、5%精喹禾灵,施药剂量为600 m L/hm2时,防除效果为65%左右,表明旱雀麦对108 g/L高效盖草能EC有一定的耐药性。The indoor and field trials were conducted to determine the sensitivity of Bromus tectorumL. in spring rape field against 108 g / L Haloxyfop-R-methyl EC,5% Quizalofop-P-ethyl EC and 240 g / L Clethodim EC three commonly herbicides.The indoor research results showed that herbicide sensitivity order was 5% Quizalofop-P-ethyl EC,240 g / L Clethodim EC,108 g / L Haloxyfop-R-methyl EC. The field test results showed that the sensitivity of Bromus tectorumL. against 108 g / L Haloxyfop-R-methyl EC was lower than that of 5% Quizalofop-P-ethyl EC and 240 g / L Clethodim EC. The control effect of 108 g / L Haloxyfop-R-methyl EC was about 65% with the doses of 600 mL / hm^2 which indicated that Bromus tectorumL. had a certain resistance to 108 g / L Haloxyfop-R-methyl EC.
