摘要
10个青贮玉米品种随机区组排列种植,进行系列指标的观察测定,结果显示:华农1号分枝多穗玉米和东陵白表现较好,株高达3m以上,产量高,抗病虫害,干物质产量分别达36948kg/hm2和35840kg/hm2,显著高于其他玉米品种,但两品种间产量无显著差异;经对10个玉米品种8项农艺性状与干物质产量相关分析显示,株高(r=0.799)、穗位高(r=0.726)和穗数(r=0.731)与产量密切相关。
10 silage Maize varieties were planted by randomly designing blocks, and observing and measuring series of index, the results showed that： .Huanong No.1 and Donglingbai maize were the best, they can resist diseases and insects, and their height exceed 3m, dry matter yield （DMY） were 36 948 kg/hm^2and 35 840 kg/hm^2 respectively and higher than other Maize varieties significantly, but there is not significant difference of DMY between the two cuhivars; by analyzing the correlation of DM yield and 8 main characters showed that individual height, spike height and spike number have the significant correlation with yield.
