【摘要】 通过品种、密度、肥力三因素随机区组试验,分析了6个青贮玉米品种在不同密度和施肥水平下的产量水平。经方差分析,品种间、密度间和品种与密度的互作间达到了极显著差异,而肥力因素的两个水平间差异不显著。多重比较结果为:龙辐单208和白鹤两个品种表现出的生物产量最高。但在不同密度栽培水平下,白鹤品种在高密度(6 500株/667m2)栽培条件下表现出的产量水平最高。更多还原

【Abstract】 The total yield of different varieties of silage maize planted at different levels of density and fertilization were studied by randomized block experiment.The results of anova analysis is that difference of varieties 、levels of density and mutual effect between varieties and density were significant,and difference of levels of fertilization were not significant.By Duncan’s Multiple Range Test,the total yield of Longfudan No.208 and Baihe were the highest among the six varieties at the same planting level.But due to mutual effect between varieties and density,the total yield of Baihe planted at high level of density(97500ha-1) was the highest.更多还原
