大豆田阔叶杂草种类多,出草时间长,特别是多雨年份,后期出草量大,必须二次用药。近年我们选择克莠灵、虎威等药剂进行了试验,取得了较好的效果。 1991年小区试验结果表明:48.5％克莠灵66.6、133、200、266毫升/亩,用药12天后的总株防效分别为61.5％、82.9％、92.3％和88％,总鲜重防效为80.9％、92.8％、98.2％和94.4％;亩用25％虎威50毫升总株及鲜重防效分别为80.4％和94％。马齿苋对两种药剂最敏感,各处理防效均为100％,对苍耳、苘麻的株防效,克莠灵66.6毫升/亩,虎威50
Soybean broad-leaved weed species, a long time to draft, especially the rainy years, late drafting, you must re-medication. In recent years, we have chosen grams of aniline, tiger Granville and other agents were tested and achieved good results. In 1991, the plot test results showed that the total plant control efficiency of 48.5% guropin 66.6,133,200,266 ml / mu after 12 days of treatment were 61.5%, 82.9%, 92.3% and 88%, respectively. The total fresh weight was effective Which was 80.9%, 92.8%, 98.2% and 94.4% respectively. The total fresh weight and control effect of 50% of Huwei using 25% Mu were 80.4% and 94% respectively. Purslane is the most sensitive to the two agents, each treatment control effect is 100%, on the Xanthium sibiricum anti-plant efficacy, goropyr 66.6 ml / mu, Tiger 50
