| 摘 要： | 该研究比较了不同浓度莠去津(播后苗前喷药处理)对谷子田间杂草的防除效果,为筛选适宜谷子生产的除草剂最佳使用浓度提供理论依据。结果表明:喷施25 d和40 d后,莠去津4 500 ml/hm_2处理株防效和鲜重防效最好,鲜重防效达到83.16%和86.43%,与喷施清水(CK)相比2 250 ml/hm处理增产效果最佳,增产率达到54.31%,3 000 ml/hm_2次之,因此2 250 ml/hm_2是谷子生产中莠去津(播后苗前喷药)使用的最佳浓度。

| Abstract: | The control effect of different concentrations of herbicide atrazine (before seedling after sowing) on weed in foxtail millet field was compared,which provide theoretical basis for screening suitable herbicides concentration for foxtail millet production.As a result,after spraying 25 and 40 d,plant control effect and fresh weight control effect were best by 4 500 ml/hm2 processing,and fresh weight control effect reached 83.16％ and 86.43％.Compared with spraying water (CK),yield-increasing effect was the best in the treatment group with atrazine at 2 250 ml/hm2,where yield growth rate was 54.31％,followed by the treatment group with atrazine at 3 000 mt/hm2.Therefore,2 250 ml/hm2 was the optiaml concentration of herbicide atrazine for millet production. |
