测试了2006年处暑、白露、秋分3个节气5个品种饲用玉米(东陵白、青贮王、科青1、科多8、巡天)的主茎单株干物质产量、初水分含量、株高、茎秆干重、叶片干重,对处暑至秋分期间饲用型玉米经济性状的变异程度、总体均值95%置信限,对秋分季节饲用型玉米经济性状的差异显著性和遗传参数进行了分析和预测,统计分析结果表明,饲用型玉米经济性状均值间均达显著(P<0.05)或极显著差异(P<0.01)。
The dry matter yield, initial moisture content and initial moisture content of main stem of five varieties of maize (Dongling white, silage king, Keqing 1, Keduo 8, and patrolling day) High, stalk dry weight and leaf dry weight. The variation degree of economic characters of forage corn during summer vacation and autumn equinox, the overall mean 95% confidence limit, the significant difference of economic traits and the genetic parameters of forage corn in autumn season Analyzed and predicted, the results of statistical analysis showed that the economic traits of forage corn reached significant (P <0.05) or very significant difference (P <0.01).
