摘　　要：对高效氟吡甲禾灵·烯草酮混剂进行了田间小区试验,结果表明:该混剂苗后应用可有效防除移栽冬油菜田中一年生禾本科杂草。在101.25～135ga.i./hm2剂量下,除草效果可达95.3%～97.5%,在67.5～202.5ga.i./hm2剂量范围内对油菜安全,不影响油菜的生长和发育,并且增产10.8%～18.2%。Field trial was conducted to investigate weed control and transplant winter rape safety for postemergence application of haloxyfop-R-methyl and clethodim. The results showed that haloxyfop-R-methyl and clethodim mixture had a good control of annual gramineous weeds. Weed control effect could be about 95.3 to 97.5% under the mixture rate of 101.25 to 135 g a.i./ha. The mixture had a good safety to transplant winter rape at the rate from 67.5 to 202.5 g a.i./ha and the yield of rape can be improved 10.8 to 18.2%.
