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。
By comparing the plots of nine maize cultivars, which are mainly popularized and cultivated in Inner Mongolia, the results of statistical analysis using the new complex test (LSR) showed that the yields of Donglingbai, Mo Bai 102 and Jiudan 118 average mu Producing fresh straw more than 7200 kilograms, good quality, is the ideal silage corn varieties; yellow desert 417, Jidan 118, the average yield of more than 550 kg of seed per acre Yiyang 101, the growth period of about 130 days, suitable for Inner Mongolia, most parts of North China Cultivation, can be used as feed corn varieties; Ji Dan 118, Zhongdan 2, yellow desert 417 comprehensive evaluation of both straw and seed, can be used as forage grass maize varieties. At the same time, a series of production-related traits such as growth period, growth rate, leaf area index, stem-leaf ratio, nutrition composition of all varieties were also analyzed and evaluated.
