摘　　要：为探明氟噻草胺与异丙隆复配对冬小麦田一年生杂草的防治效果及对小麦产量的影响,以“马兰一号”、播娘蒿和雀麦为调查对象,采用田间试验,测定了不同剂量35%氟噻草胺·异丙隆悬浮剂对冬小麦田一年生杂草的株防效、鲜重防效及冬小麦产量。试验结果表明:在冬小麦1叶一心期至2叶一心期,一年生杂草2~5叶期,以35%氟噻草胺·异丙隆悬浮剂喷雾处理茎叶,对试验地播娘蒿和雀麦均有较好的防效,末次株防效为83.47%~88.53%,鲜重防效为84.92%~90.81%,且对冬小麦安全,其产量与人工除草的产量差异不显著,显著高于空白对照,有较高的增产率。35%氟噻草胺·异丙隆悬浮剂推荐剂量为420~840 g.a.i./hm^(2)。A field experiment was conducted to evaluate the control effects of flufenacet combined with isoproturon on annual weeds(Descurainia sophia and Bromus japonicus)in the field planted with the winter wheat cultivar'Malan 1'and the influence on the winter wheat yield.The control effects regarding plant number and fresh weight of annual weeds and the winter wheat yield were measured.The results showed that flufenacet·isoproturon 35%suspension concentrate demonstrated good control effects on annual weeds from the 1-leaf and 1-bud stage to the 2-leaf and 1-bud stage of winter wheat and at the 2 to 5-leaf stage of annual weeds.Spraying flufenacet·isoproturon 35%suspension concentrate on stems and leaves demonstrated the control effect of 83.47%-88.53%regarding plant number and 84.92%-90.81%regarding fresh weight at the last time of application.Moreover,the compound herbicide was safe for winter wheat.The compound herbicide treatment showed no significant difference in the winter wheat yield compared with artificial weeding and higher winter wheat yield than the blank control.The recommended dose of flufenacet·isoproturon 35%suspension concentrate was 420-840 g.a.i./hm^(2) in winter wheat fields.
