摘要:
高粱"赤杂28"苗前封闭使用3种除草剂,1种复配剂;苗后茎叶使用2种除草剂,1种复配剂。通过对田间杂草防效和"赤杂28"产量的对比与分析,选出能有效防除杂草又保证"赤杂28"正常生长的除草剂。结果表明,播后苗前每667 m2使用129.2 m L 72%异丙甲草胺复配323 m L 38%莠去津封闭喷雾,出苗后于高粱2~4叶期每667 m2使用38%莠去津323 m L喷雾,以上2种方法可安全用于高粱杂交种"赤杂28"的杂草防治。
Abstract:
Three kinds of herbicides and a compound agent was applied before emergence of Sorghum‘Chiza 28’and two kinds of herbicides and a compound agent was applied after emergence. Herbicides which had effectiveweed controlling and ensure a normal growth of‘Chiza 28’were selected by comparison and analysis of weed con-trol effect and yield of grains. The results showed that after sowing and before emergence, 129.2 m L of 72% ISO-Propylene compound and 323 m L 38% Atrazine per 667 m2 can be used for closed spray, and after emergence andin 2~4 leaf stage 323 m L of 38% atrazine per 667 m2 can be applied. The above two methods are safe for weed con-trolling of sorghum hybrid‘Chiza 28’.
