摘要
[目的]筛选适宜糜子生产的除草剂.[方法]通过小区试验研究不同除草剂对糜子田间主要杂草的防除效果.[结果] 57％2,4-D丁酯乳油、56％2甲4氯钠盐可湿性粉剂对糜子田间杂草有一定的防除效果.喷药后15和30 d 56％2甲4氯钠盐可湿性粉剂的株防效分别为81.32％和87.92％,其鲜重防效高于57％2,4-D丁酯乳油.与喷施清水不除草处理相比,喷施56％2甲4氯钠盐可湿性粉剂、57％2,4-D丁酯乳油处理糜子的增产率分别为97.36％、59.61％.56％2甲4氯钠盐可湿性粉剂对糜子田间杂草的防除效果优于57％2,4-D丁酯乳油.[结论]试验结果为糜子田间杂草的化防提供了理论依据.
Abstract
[Objective] The aim was to find an appropriate herbicide for broomcorn millet production.[Method] Through plot experiment,the control effects of different herbicides on weeds in broomcorn millet field were studied.[Result] The results showed that 57％ 2,4-D butylate and 56％ methoxone had a certain control effect on weeds.Mter spraying for 15 and 30 d,plant control effect of 56％ methoxone were 81.32％ and 87.92％,while control effect of fresh weight was higher than 57％ 2,4-D butylate.Compared with spraying water,the yield of broomcorn millet increased 97.36％ and 59.61％.The control effect of 56％ methoxone on weeds was better than 57％ 2,4-D butylate in the broomcorn millet field.[Conclusion] The results provide theoretical basis for chemical control of weeds in broomcorn millet field.
