| 摘 要： | 研究了2,4-D丁酯与多效唑混用对小麦产量及产量构成因素的影响.结果表明,喷施2,4-D丁酯的小区杂草株防效极显著好于没有喷施2,4-D丁酯的小区;2,4-D丁酯显著抑制小麦的生长,但随着多效唑浓度的增加,这种影响明显降低.同一多效唑水平下,随着2,4-D丁酯用量的增加,小麦旗叶叶绿素含量减少;同一2,4-D丁酯用量下,随着多效唑浓度的增加,小麦旗叶叶绿素含量增加.2,4-D丁酯显著抑制小麦旗叶面积的扩大,而且处理间差异性有扩大趋势,多效唑的存在,抑制了2,4-D丁酯作用.从产量方面来看,最佳处理组合为多效唑2.25 kg/hm2+2,4-D丁酯15 g/hm2.

| Abstract: | In this experiment,random complete block design was used.Impact of 2,4-D and PP333 combination treating on wheat yield composition was studied.Weed control effect,flag leaf area,chlorophyll content of flag leaf and yield composition were measured.Results indicated that PP333 affected the effect of 2,4-D.The best treat combination was PP333(2.25 kg/hm2) 2,4-D(15 g/hm2). |
