摘　　要：【目的】筛选出适宜在天山北坡平原荒漠区推广种植的紫花苜蓿品种。【方法】采用单因素随机区组设计,测定9个紫花苜蓿品种的株高、草产量、品质等指标,并利用灰色关联法对9个品种进行综合评价。【结果】随种植年限增加,供试材料的鲜草和干草产量均呈下降趋势,其中第1年的干草产量占比较高,平均为37.77%;佰苜341的株高积累量最大,为939.8 cm,显著高于其他品种;骑士T干草总产量、粗蛋白含量和相对饲喂价值最高,分别为61602.03 kg/hm^(2)、16.83%和119.16%;灰色关联度综合评价结果由高到低的顺序为:骑士T>佰苜202>大银河>阿迪娜>佰苜341>佰苜371>挑战者>佰苜401>康赛。【结论】骑士T的综合表现较好,建议在天山北坡平原荒漠灌区引种种植。【Objective】In order to identify alfalfa varieties suitable for cultivating in the desert area of the plain on the northern slope of Tianshan Mountains.【Method】The single factor randomized block design was used to deter-mine the plant height,grass yield and quality of nine alfalfa varieties.The grey correlation method was used to com-prehensively evaluate these traits.【Result】With the increase in cultivating years,the dry and fresh grass yield of al-falfa showed a downward trend.The dry grass yield in the first year of alfalfa growth accounted for 37.77%on aver-age.The maximum plant height accumulation of Baimu 341 was 939.76 cm,which was significantly higher than that of other varieties.The total hay yield,crude protein content and relative feeding value of Knight T were the highest,which were 61602.03 kg/hm^(2),16.83%and 119.16,respectively.The comprehensive evaluation results of grey cor-relation degree ranked from high to low as:Knight T>Baimu 202>Galaxie Max>Adrenalin>Baimu 341>Baimu 371>Survivor>Baimu 401>Concept.【Conclusion】The overall performance of Knight T was the best,thus it was recommended to be introduced and planted in the desert irrigation area of the northern slope of Tianshan Mountains.
