72%都尔乳油是一种高效、低毒、选择性强的土壤处理除草剂.它通过植物幼芽与幼根吸收.其中单子叶禾本科杂草主要是芽鞘吸收;双子叶植物是通过幼芽与幼根吸收.当药剂进入植物体后抑制幼芽与幼根的生长,敏感的杂草在发芽出土前或刚刚出土即中毒死亡.主要作用机制是抑制发芽种子的蛋白质合成,抑制细胞的有丝分裂.该药剂理化性质稳定,不易挥发与光解.根据都尔的特点,我团九六年首次在地膜甜菜田大面积推广应用并在棉田和瓜地进行示范.推广应用面积达9300亩,占甜菜播种面积的61.8%.解决了甜菜田化学除草一大难题,解决了多年来没有解决的问题,为解放劳力开辟了新途径.现将应用效果调查整理报告如下:
72% Bole Emulsifiable Concentrate (ECM) is an efficient, low toxicity and selective soil treatment herbicide which is absorbed by plant buds and young roots, of which monocotyledonous weeds are mainly buds and sheaths, and dicotyledons are produced by When the agent enters the plant body, it suppresses the growth of sprouts and young roots, and the sensitive weeds die before germination or just excavated.The main mechanism of action is to inhibit the protein synthesis of the germinating seeds, inhibit the growth of the cells Of the chemical and physical properties of the stable, non-volatile and photolysis.According to the characteristics of Dole, I regiment for the first time in 96 large-scale promotion and application of mulberry beet in cotton fields and melon to demonstrate .Application area of 9,300 acres , Accounting for 61.8% of the area planted sugar beet.To solve the beet field chemical weeding a major problem, solve the problem over the years did not solve, for the liberation of labor has opened up new avenues.The application of the effectiveness of the survey report is as follows:
