白菜种类很多,根据食用分为小白菜、贩白菜和冬贮大白菜,属密植或半密植蔬菜,杂草发生较重,往往因防治不及时影响白菜幼苗生长,从而降低白菜的产量和质量.经过几年的研究,筛选出几种对白菜安全、除草效果较好的除草剂.现将试验结果总结如下: 1.温室盆载药害试验结果表明60％丁草胺100毫升/亩,对白菜无不良影响,株数虽比对照少,但鲜重反而增加,单株重量高于对照。72％杜耳乳油100毫升/亩.对株数和鲜重均有轻微影响,经统计分析与对照差异不显著,生长中、后期缓解,无影响。25％乙草胺100 There are many kinds of cabbage, which are divided into Chinese cabbage, Chinese cabbage and Chinese cabbage which are stored in winter. They are close-planting or semi-dense planting vegetables. The weeds are heavy, and the growth and the quality of Chinese cabbage are often not controlled by the prevention and treatment. After several years of research, we have screened out several herbicides that are safe and have good herbicidal effect on Chinese cabbage.The results of the experiment are summarized as follows: 1. The results of pesticide damage experiments in greenhouse showed that 60% butachlor 100ml / Cabbage without adverse effects, although the number of strains less than the control, but the fresh weight but increased weight per plant higher than the control. 72% Dulcimer oil 100 ml / mu. The number of trees and fresh weight have a slight impact, the statistical analysis and the control difference was not significant, growth, late mitigation, no effect. 25% acetochlor 100
