摘　　要：【目的】通过比较研究干旱胁迫下10份豆科牧草的苗期抗旱性,为抗旱牧草品种的选育提供理论依据。【方法】采用室内盆栽试验方法对牧草进行连续干旱胁迫处理,通过隶属函数标准差系数赋予权重法对不同豆科牧草进行抗旱性综合评价。【结果】将10份豆科牧草的苗期抗旱性从强到弱的顺序排列为红豆草>百脉根>红三叶>早熟沙打旺>白三叶>南方型百脉根>西伯利亚驴食豆>草莓三叶>北方型百脉根>多变小冠花。【结论】建议在新疆干旱区种植推广牧草时,选择抗旱性强的红豆草。[ Objective ] Comparative study under the drought stress, which might provid was made on drought resistance of 10 legume forage in seedling e a theoretical basis for breeding forage drought resistance. [ Method] Indoor pot experiment was done on forage for continuous drought stress. Comprehensive evaluation was carried out of drought resistance for different forage legumes through the subordinate function of the standard deviation coefficient given weighting method. [ Result] The drought resistance of 10 legume forage was arranged as the order from strong to weak： Onobrychis viciaetolia Scop. 〉 Lotus corniculatus L. 〉 Trifolium pratense L. 〉 Astragalus adsurgens Pall. cv. Zaoshou 〉 Trifolium repens L. 〉 Lotus L. （Nanfang） 〉 Onobrychis tanaitica Spreng. 〉 Trifolium fragiferum L. 〉 Lotus L. （Beifang） 〉 CoroniUa varia L. [Conclusion] Based on the comparison and analysis, the author suggested selecting Onobryehis vieiaetolia Seop. which has relatively strong drought -resistance when forage grass is planted in Xinjiang arid area.
