不同玉米品种的青贮产量和营养品质比较分析

Analysis on Silage Production and Nutritional Quality in Seven Different Maize Hybrids

本研究比较了7个不同玉米品种的青贮产量和青贮营养品质,结果发现品种间产量和品质性状存在显著差异。其中中北410、中北412等产量较高,但品质一般,应通过一定的栽培管理措施对其营养品质加以改善;组合6013-18/5947在青贮品质中均满足优质青贮玉米的要求,产量也较高,是产量和品质两方面均较好的组合,比较适于对青贮品质要求较高的畜牧区的种植;在选择示范推广青贮品种时,应兼顾青贮产量和品质两个方面,不可只看产量而忽视品质。

Seven maize hybrids were analyzed on silage production and nutritional quality. Significant differences were observed on those traits. Among them, the hybrids＂ Zhongbei 410＂ and＂ Zhongbei 412＂ performed best in silage production, but not in nutritional quality. The hybrid＂6013-18/5947＂ performed well in both of them. Both of silage production and nutritional quality should be considered in the choice of hybrids for release.
