中文摘要	以俄罗斯杂花苜蓿、金皇后紫花苜蓿和阿尔冈金紫花苜蓿为对照材料,以暖温半干旱气候区为对照区,采用育成的3个抗寒紫花苜蓿品系GNKH-1,GNKH-2和GNKH-3进行种植试验,对营养价值进行综合评价。结果表明,高寒湿润气候区苜蓿粗蛋白、粗脂肪、酸性洗涤纤维和中性洗涤纤维、粗灰分、叶茎比含量均低于暖温半干旱气候区;高寒湿润气候区苜蓿材料无氮浸出物含量和相对饲喂价值均高于暖温半干旱气候区;其中,高寒湿润气候区GNKH-3和GNKH-2的粗蛋白含量最高,分别为18.07%和17.56%;叶茎比也最高,分别为1.19和1.16。GNKH-1和GNKH-2粗脂肪含量较高,分别为2.68%和2.46%。GNKH-3和GNKH-1的中性洗涤纤维含量较低,分别为34.15%和32.55%;粗灰分、无氮浸出物和RFV 含量相对较高,分别为10.01%和9.25%、35.45%和41.43%、184.68和199.86。采用灰色关联度模型综合评价苜蓿材料在两个气候区的营养价值,高寒湿润气候区,6个供试苜蓿材料的营养价值综合排序为:GNKH-2> GNKH-3>俄罗斯杂花>GNKH-1>阿尔冈金>金皇后;暖温半干旱气候区,6个供试材料的营养价值综合排序为:金皇后>阿尔冈金>俄罗斯杂花> GNKH-3 > GNKH-1> GNKH-2。
英文摘要	The nutritive value of 3cold-resistant strains of Medicago sativa (GNKH-1、GNKH-2、GNKH-3) was comprehensively evaluated in Lanzhou by choosing M.varia,M.sativacv.Conden Empress and M.sativa cv.Algonguin as controls.Result showed that the average contents of CP,CF,ADF and NDF,CA,leaf-stem ratio of alfalfa in cold humid climate zone were lower compared to that in the warm semi-arid climate zone.The contents of nitrogen free extract and relative feed value were higher compared to that in the warm semi-arid climate zone.Among which,the CP contents of GNKH-3and GNKH-2were the highest(18.07%and 17.56%),as well as the leaf-stem ratio(1.19and 1.16respectively).The CF contents of GNKH-1and GNKH-2were high(2. 68%and 2.46%),while the NDF contents of GNKH-3and GNKH-1were low (34.15%and 32.55%);Meanwhile the content of crude ash,nitrogen free extract and relative feed value were relatively high(10.01%and 9. 25%,35.45%and 41.43%,184.68and 199.86respectively).Environmental factors played a dominant role in terms of nutritive value.The comprehensive order of nutritive value of 6materials in cold humid climate zone was GNKH-2> GNKH-3>M.varia>GNKH-1> M.sativacv.Algonguin> M.sativacv.Golden Empress; and that in warm semi-arid climate zone was M.sativa cv.Golden Empress> M.sativa cv.Algonguin> M. varia > GNKH-3> GNKH-1> GNKH-2.
