| 摘 要： | 本研究对6个苜蓿（Medicago sativa）（品）种的主要营养成分包括粗蛋白、粗脂肪、钙、磷、粗灰分、中性洗涤纤维、酸性洗涤纤维及其产量进行了研究。结果表明，6个苜蓿（品）种中粗蛋白含量最高的是龙牧806（M.sativa cv．Longmu 806），最低的是龙牧801（M.sativa cv．Longmu 801）；粗脂肪含量最高的是龙牧801，最低的是龙牧806；钙含量最高的是龙牧806，最低的是龙牧801；磷含量最高的是龙牧803（M.sativa cv．Longmu 803）和黄花苜蓿（M.falcata），最低的是杂花苜蓿（M.varia）；粗灰分含量最高的是龙牧801，最低的是肇东苜蓿（M.sativa cv．Zhaodong）；产量最高的是龙牧801，最低的是龙牧806。相关分析表明，不同苜蓿（品）种同一指标间差异不显著。利用灰色关联度分析对主要营养成分进行综合评价表明，6个苜蓿（品）种营养价值从高到低依次为肇东苜蓿、杂花苜蓿、龙牧803、龙牧801、龙牧806和黄花苜蓿。本研究结果可对今后苜蓿的引种与选育有一定的指导意义。

| Abstract: | The nutritional ingredients, incruding crude protein (CP), crude fat (CF), crude ash, calcium (Ca), phosphorus, neutral detergent fiber (NDF) and acid detergent fiber (ADF), of six alfalfa (Medicago sativa, M.varia, M.falcata) varieties and their yields were studied. The results indicated that among the six varieties, Long Mu 801 appeared the highest contents in CF, crude ash, NDF, ADF and the highest yield; Long Mu 806 appeared the highest contents in CP and Ca, and the lowest CF content and yield; while M.varia showed the lowest content in P, NDF and ADF. The correlation analysis showed that there were no significant differences among different varieties for the same index. The results of grey correlative degree analysis of main nutritional components showed that nutritional values of 6 alfalfa varieties from high to low were Zhaodong, M.varia, Long Mu 801, Long Mu 803, Long Mu 806 and yellow alfalfa. The evaluation results have certain guiding significance for the future introduction and breeding of alfalfa varieties. |
