摘要：

旨在更加科学地筛选高粱育种田除草剂种类及使用时间,为高粱育种田的管理提供理论依据。以6种高粱种质和3种除草剂为试验材料,用方差分析法测得适合夏播高粱育种田使用的除草剂及其使用时间。结果表明：T3对出苗率影响较小,各种质平均出苗率为94.32%。处理间药害分析,T6最重,平均达3.87%,与其他比较,差异均达极显著水平,T2无药害,T4较轻,平均为0.13%。种质间分析,苗前处理产生的药害差异较大,非杂交种药害较重,平均值1.44%,显著高于杂交种的1.07%。所有处理的防草效果均比较理想,T6除草效果最佳,各种质间的草害平均值为0.11%。综合分析,T4处理既可以有效防治田间杂草,又对各种质产生的药害较轻。

Abstract:

The aim of this study is to screen the herbicide types and using time scientifically in the sorghum breeding fields, and provide a theoretical basis for the management of sorghum breeding field. Six kinds of sorghum germplasms and three herbicides were used as experimental materials, and the suitable herbicides and using time were determined by variance analysis. The results showed that: T3 had little effect on the sprouting rate, and the average sprouting rate of sorghum germplasms was 94.32%. The herbicide hazard of T6 was the worst, its average value was 3.87%; compared with other treatments, the difference was obviously significant. T2 had not toxicity, T4 was mild, and their average value was 0.13%. According to the germplasms analysis, there was a significant difference in the herbicide hazard caused by pre-seedling treatment, and herbicide hazard on the non-hybrid strains was more serious with an average of 1.44%, which was significantly higher than that of hybrid strains (1.07%). The weed control effect of all treatments was ideal, and T6 had the best effect, the mean value of weeds damage among different strains was 0.11%. In conclusion, T4 could effectively control weeds in the field and cause less harm to sorghum germplasm.
