[Objective] The aim was to study the growth traits of different alfalfa varieties were introduced in alpine and saline-alkaline area. [ Method] The number of maturity plants, fresh and dry weight, plant height of six abroad introduced alfalfa varieties(WL323、3-1、4-1、4-2、4-2H and FGI363 ) and two domestic varieties( Aohan and Longmu 801 ) were compared respectively in the first year. [ Result] The results showed that the number of maturity plants, fresh and dry weight and plant height of six abroad introduced alfalfa varieties were better than two domestic varieties, and the foreign varieties had higher ability to resist against drought, cold and saline-alkaline. [ Conclusion] The study lays a foundation for fully utilization of soil in alpine and saline-alkaline area and the development of forage grass industry.%[目的]研究不同的苜蓿品种在高寒盐碱地区的生长性状.[方法]分别对6个国外引进苜蓿品种WL323、3-1、4-1、4-2、4-2H、FGI363,2个国内传统苜蓿品种敖汉及龙牧801第一年的成苗株数、鲜干重、株高等性状进行对比研究.[结果]国外引进的6个苜蓿品种的成株数、鲜干重和株高都好于国内的2个品种,有着更高的抗旱、抗寒和抗盐碱性能.[结论]该研究为高寒盐碱地区土壤的充分利用以及牧草产业的发展奠定了基础.
