摘　　要：为了研究除草剂混配对小麦田间杂草的防效,测定了15%顶尖WP或6.9%骠马EW与20%氯氟吡氧乙酸EC混配对小麦田杂草的防效、田间透光率、杂草对水肥的吸收量和小麦产量。结果表明,除草剂混配对小麦田间杂草的综合密度防效和综合鲜重防效分别达到98.21%~100.00%和99.46%~100.00%,显著优于单剂的防效。除草剂混配能有效抑制杂草的株高,顶尖WP与最低剂量的氯氟吡氧乙酸混配,野燕麦即被全部防除,大巢菜和猪殃殃的株高亦显著降低。除草剂混配使用能显著提高小麦田间不同部位的透光率,小麦顶部透光率比对照增加54.08%~57.20%;离地50 cm的透光率比对照增加47.21%~52.73%;离地10 cm的透光率比对照增加22.84%~27.44%。除草剂混配使用降低了杂草对水肥的吸收,高剂量的组合中,杂草的水肥含量均降为零。除草剂混配喷施后增产效果显著,增产率达到124.63%~172.88%。The control effects,the light penetration rate,the Absorbtion of nutrition elements and moisture,and the yields of wheat were investigated to evaluate the application prospect of the mixture herbicide of fluroxypyr with Topik or puma super to enlarge the weeds control spectrum of fluroxypyr and control the main monocotyledon and dicotyledon weeds in wheat fields.The results showed that the mixture herbicide markedly enhanced density control effects for main weeds from 98.21% to 100.00% and fresh weight cont...
