| 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。

| Abstract: | 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 /hm2and 35 840 kg/hm2 respectively and higher than other Maize varieties significantly,but there is not significant difference of DMY between the two cultivars;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. |
