摘　　要：为了明确33%二甲戊灵乳油对胡萝卜田杂草的防除效果和安全性,分别设置了单独使用、与8%精喹禾灵微乳剂配合使用及与覆膜配合使用等6个处理。结果表明,与33%二甲戊灵乳油2个剂量1 500,2 250 m L/hm2单独使用相比,其与精喹禾灵配合使用后,药后株防效和鲜质量防效均达到81.79%和83.62%以上;与覆膜相配合的处理,株防效和鲜质量防效则达到了87.88%和95.03%以上,产量比对照增加52.61%~92.68%,且安全、无药害症状。因此,推荐33%二甲戊灵乳油使用量为1 500~2 250 m L/hm2时,可以和精喹禾灵配合或与覆膜配合使用,尤其与覆膜相结合使用效果更好。The study is to confirm the control effect and security of pendimethalin 33% SC against weeds in carrot filed, setting up six treatments, such as separate use, used with quizalofop-p-ethyl 8% ME, and covered with plastic film, etc. The results showed that compared with the two doses（1 500, 2 250 m L/hm2）of pendimethalin 33% EC which used alone, used with quizalofop-p-ethyl 8% ME,the control effect and fresh quality control effect reached above 81.79% and 83.62%, respectively, when used with plastic film reached above 87.88% and 95.03%, respectively. The carrot yield increased by 52.61%-92.68% compared with the control, and it was safe and no drug damage symptoms to carrot. Therefore, it is recommended that the usage of 1 500 ~ 2 250 m L/hm2 of 33% dimethylpentyl EC can be used in combination with quizalofop-p-ethyl 8% ME or with plastic film, especially combination with plastic film, the effect is better.
