为全面研究紫花苜蓿的产量性状、品质特性及品种适应性，采用灰色关联分析方法对6个紫花苜蓿品种在湘北地区的引种表现进行综合评价，考察指标为干草产量、株高、分枝数、叶茎比、粗蛋白含量、中性洗涤纤维含量和酸性洗涤纤维含量。结果表明，干草产量对综合评价的贡献最大，其次是粗蛋白含量；6个紫花苜蓿品种中 CW403的综合生产性能表现最优，SIMA575表现最差。这说明 CW403较适宜在湘北地区引种种植。
為全麵研究紫花苜蓿的產量性狀、品質特性及品種適應性，採用灰色關聯分析方法對6箇紫花苜蓿品種在湘北地區的引種錶現進行綜閤評價，攷察指標為榦草產量、株高、分枝數、葉莖比、粗蛋白含量、中性洗滌纖維含量和痠性洗滌纖維含量。結果錶明，榦草產量對綜閤評價的貢獻最大，其次是粗蛋白含量；6箇紫花苜蓿品種中 CW403的綜閤生產性能錶現最優，SIMA575錶現最差。這說明 CW403較適宜在湘北地區引種種植。

In order to com prehensively study the yield trait,quality characteristic and adaptation of the varieties,gray relevancy analysis m ethod w as used in this study to assess the property of 6 Medicage sativa,including hay yield,plantheight,branch num ber,ratio ofstem and leaf,and the contentofcrude protein,NDF and ADF.The resultsindicated thatthe greatestcontribution to the com prehensive accessm entw as hay yields, follow ed by the content of crude protein. In addition, CW 403 had the best com prehensive production property am ong the 6 varietiesand SIMA 575 had the w orstproperty.Itcan be concluded thatCW 403 issuitable to be planted in N orthern H unan.
