摘　　要：鸭跖草为一年生晚春杂草,分布范围广,抗药性强,防除难度大。本试验讨论了鸭跖草防除的时期和方法。结果表明,防除鸭跖草应以播后苗前土壤处理为主,茎叶处理为辅,结合人工防除。土壤处理施用禾耐斯+广灭灵+赛克,株防效达73.4%,鲜重防效达89.7%;乙草胺+广灭灵+赛克的株防效达68.4%,鲜重防效达86.5%。人工防除时应在土表含水量低于13%,且天气晴朗时进行。As a kind of annual late-spring weed, dayflower(Commelina Com munis L.), which existed widely in dry land, was very difficult to control. The test had studied the proper time and method of controlling dayflower. The result s showed: soil treatment in pre-emergence period was the main way to control day flower and treatment in post-emergence period was assistant way. Weed control ef ficiency (WCE) was excellent by application of acetochlor + clomazone + metribuz in when treated in pre-emergence period; Dayflower was controlled effectively wh en moisture was less than 13% and there was sunshiny in future days.
