摘　　要：在河西走廊灌区对12个适宜于灌溉条件下种植的速生型紫花苜蓿材料的粗蛋白(CP)、饲喂价值(RFV)2项营养指标及单株生长高度、单株分枝数、鲜草产量、干草产量、茎叶比、植株数目6项农艺性状指标进行测定,并采用灰色关联度法对12个紫花苜蓿材料从产量、营养品质及综合生产性能3个方面分别进行综合评价。结果表明:在产量指标综合评价中,G材料、新疆大叶紫花苜蓿和I材料排名前3位;在营养指标综合评价中,新疆大叶紫花苜蓿、I材料排名前2位,排名第3位的是H材料,G材料排名第4位;生产性能指标综合评价中,G材料、新疆大叶紫花苜蓿、I材料排名前3位。综合3个方面的评价结果,G材料、新疆大叶紫花苜蓿、I材料表现优异,适宜在河西走廊灌溉地区大范围推广种植。In this study, two nutrition indexes and six agronomic characters including crude protein content （CP）, relative feed value （RFV）, plant height, tillering branches, fresh yields, hay yields, stem/leaf ratio and plant density of 12 alfalfa varieties grown in the irrigated area of Hexi Corridor were evaluated by the grey correlation analysis model. The results showed that The G, Xingjiang Daye and The I were the top three on the yield-index value system; Xingjiang Daye, The I, The H and The G were the top four on the nutritive-index value system; The G, Xingjiang Daye, The I were the top three on the general performance value system. In general，The G, Xingjiang Daye and The I preformed well in the study area, which indicated that these three varieties are suitable for cultivation in the irrigated area of Hexi Corridor.
