摘要
【目的】全面和准确地得出沙尔套山天然割草场上常见豆科牧草的营养价值优劣排序。【方法】将沙尔套山天然割草场上常见的10种豆科牧草进行营养成分分析,分别采用4种常见营养价值评价模型进行评价,并将4种评价结果进行二次综合分析。【结果】结果表明,干物质含量较高的牧草为黄花苜蓿(Medicago falcata)、罗马苜蓿(M.falcata var.romanica)、野火球(T.lupinaster)及西伯利亚驴食豆(Onobrychis tanaitica),其含量之间差异不显著(P>0.05),粗蛋白含量最高的牧草为广布野豌豆(Vicia cracca),粗灰分含量最高的牧草为红花车轴草(Trifolium pratense)和广布野豌豆,其含量之间差异不显著(P>0.05),粗脂肪含量最高的牧草为野火球,中性洗涤纤维含量最低的牧草为线叶野豌豆(V.tenuifolia),酸性洗涤纤维含量最低的牧草为广布野豌豆,钙含量最高的牧草为广布野豌豆,磷含量最高的牧草为线叶野豌豆。【结论】二次综合4种评价模型将沙尔套山10种豆科牧草进行营养价值排序,由高至低依次为:广布野豌豆(Vicia cracca)>红花车轴草(Trifolium pratense)>线叶野豌豆(V.tenuifolia)>黄花苜蓿(Medicago falcata)>罗马苜蓿(M.falcata var.romanica)=草原香豌豆(Lathyrus pratensis)=西伯利亚驴食豆(Onobrychis tanaitica)>白花车轴草(T.repens)>块茎香豌豆(L.tuberosus)>野火球(T.lupinaster)。
【Objective】It aimed to sequence familiar legume forages with the nutritional value as the indexes.【Method】The nutritional ingredients of ten kinds of legume forages found in Shaertao Mountain,Xinjiang Zhaosu were evaluated by four familiar nutritional value models and their evaluation results were discussed by weighted analysis method. 【Result 】The results indicated that Medicago falcate,M. falcata var. romanica,T. lupinaster and Onobrychis tanaitica is higher in dry matter. Vicia cracca is highest in crude protein. Trifolium pretense and Vicia cracca is higher in crude ash. T. lupinaster is highest in ether extract. V. tenuifolia is lowest in neutral detergent fiber. Vicia cracca is lowest in acid detergent fiber. Vicia craccais highest in calcium. V. tenuifolia is highest in phosphorus.【Conclusion】The order of ten kinds of legume forages＇ nutritional value was（ from high to low） ： Vicia cracca Trifolium pretense Vicia tenuifolia Medicago falcate Medicago falcata var. romanica = Lathyrus pratensis = Onobrychis tanaitica Trifolium repens Lathyrus tuberosus Trifolium lupinaster.
