几种除草剂防治白花三叶草苗期杂草试验

The Experiment of Herbicides against Weeds of Trifolium repens L. in seedling period

通过几种除草剂对白花三叶草(Trifolium repens L).苗期杂草防除试验,证明15%精稳杀得乳油900ml/hm2、5%精禾草克乳油750ml/hm2、6.9%骠马水剂900ml/hm2、20%氯嘧磺隆可湿性粉剂60g/hm24种除草剂不仅除草效果好,而且对白花三叶草安全;75%百阔净胺盐水剂1200ml/hm2、20%使它隆乳油900ml/hm2、75%巨星干燥乳剂21g/hm2药害严重,不宜采用。

The effeets of herbicides on weeds of Trifolium repens L. in seedling period were studied. The results showed that the 4 kinds of herbicides （15% fluazifop-p-butyl EC 900ml/hm^2, 5% quizalofop-p-ethyl EC 750ml/ hm^2, 6.9% fenoxaprop-p-ethyl SL 900ml/hm^2, 20%chlorimuron-ethyl SP 60g/hm^2） had good effects on weeds and were very safe, but 75% MCPA SL 1200ml/hm^2, 20%fluroxypyr EC 900ml/hm^2 and 75%tribenuron-methlyl WDG 21g/hm^2 were bad and were not to be adopted.
