氯嘧磺隆防除大豆杂草试验研究

Study on The Experiment of Weeding The Herbs in Soybean Field By Using Chlorimuron-merhyl

用20％氯嘧磺隆进行大豆田杂草防除试验,结果表明:氯嘧磺隆可以作为黑龙江东部地区大豆田主要田间杂草防除药剂,75g/hm2和125 g/hm2(商品量)分别为其作为单一药剂使用时的使用低限和高限。作为单一药剂使用效果不太理想,而以氯嘧磺隆为主要成分的复合试剂可有较好的杂草防除效果和产量效应。

In this research, the phytocide of 20% Chlorimuron-merhyl was involved. The results showed that the Chlorimuron-merhyl could be used for weeding the herbs in soybean field in east of Heilongjiang province. When it was employed as unitary medicament, the quantity of 75g/hm2 and 125g/hm2 should be the least limit and the highest limit. However, the effect was not well yet when it was employed as unitary medicament, but the complex medicament that the Chlorimuron-merhyl being primary component should have the prefer effect and the higher yield.
