【摘要】 通过对内蒙古地区目前主要推广栽培的九个玉米品种的小区对比试验、运用新复极差测验(LSR法)对产量进行统计分析的结果表明,东陵白、墨白102、吉单118平均亩产鲜秸秆7200公斤以上,质量好,是理想的青贮玉米品种;黄漠417、吉单118、吉单101平均亩产籽量550公斤以上,生育期130天左右,适合内蒙古、华北大部分地区栽培,可作为饲料玉米品种;吉单118、中丹2号、黄漠417从秸秆和籽实两方面综合评价,可作为饲草料兼用型玉米品种。同时对各品种的生育期、生长速度、叶面积指数、茎叶比、营养成份等一系列与生产有关的性状也作了分析和评价。更多还原

【Abstract】 Nine maize cultivars were used in our experiments. We set up a field comparative system for the experiments,and analysed the yields of these cultivars by the LSR method. The results indicate that the average yields of silage corn cultivars of Dong Ling Bai,Mexico 102 and Jidan 118 were more than 7200kg/mu inspectively can be used for silage. While the seed productions of Huang Mo 417,Jidan 118 and Jidan 101 were more than 550kg/mu individually can be used for the seed production. Besides,Jidan 118,Zhongdan 2 and Huangmo 417 can be used for dual purpose.更多还原
