摘要
[目的]筛选适合春谷生产的除草剂.[方法]通过小区试验研究不同除草剂不同浓度下的防除效果.[结果]莠去津播后苗前用药和苗后(3~5叶期)用药在整体的杂草防除效果方面表现良好,对谷苗药害小,但苗后(3~5叶期)用药对单子叶杂草的防除效果较差.谷友对单、双子叶杂草的防效均比较稳定,对谷苗药害小.2,4-D丁酯在高浓度时对杂草有较好防效,但药害随浓度增加而加重.二甲四氯钠对杂草的防除效果较差,对谷苗药害严重.[结论]试验结果为春谷区谷田除草剂使用提供了理论依据.
Abstract
[Objective] The aim was to select the millet production of herbicides.[Method] The effects of different concentrations of herbicides were studied by plot experiment.[Result] The atrazine preemergence and postemergence treatment (3-5 leaves stage)showed good performance in the overall effect of weed control,and crop phytotoxicity was small,but had the poor control effect on monocotyledonous weeds.Monosulfuron plus propazine WP prevention effect on single and dicotyledonous weeds were relatively stable,and had small seedling injury.2,4-D butyl ester had better control effect on weeds at high concentration,but the damage increased with the increase of concentration.Methoxone on weed control effect was poor,and had severe phytotoxicity on seedling.[Conclusion] The results provide a scientific basis for the use of herbicides show millet.
