为了有效的控制杂草生长,多年来我们本着除草要“除早、除小、除了”的原则.采用人工除草和化学除草(除草醚)相结合的方法,取得了很好的效果.具体作法:播种后2～3d,杂草幼芽没出土之前,当表土层稳定后,把40%除草醚乳粉,按3g/m~2计算,先用乙醇溶化,然后兑成1%浓度,用喷雾器喷洒床面.一个月后用同样的方法再喷一遍,每平方米用量5g.经过两次喷洒,可以杀死苗床1a生禾本科杂草的幼芽.晴天喷施效果好,气温越高,杀草效果越好.
In order to effectively control the weed growth, we have been adhering to the principle of “except early, except small, except for weeding” for many years, and achieved good results by combining artificial weeding with chemical weeding (weed herbicide) Practice: 2 ~ 3d after sowing, weed sprouts did not unearthed before the topsoil stabilized, 40% of weeding ether milk powder, according to 3g / m ~ 2 calculation, first dissolved in ethanol, Spray the bed with a sprayer. Use the same method a month later to spray again, the amount of 5g per square meter. After two sprays, you can kill seedlings 1a grass grasses weeding buds. Sunny spray good effect, the temperature is higher High, kill grass the better.
