摘　　要：在柴达木盆地中度盐碱地上,对6个紫花苜蓿品种进行耐盐适应性及生产性能评比试验,结果表明:各苜蓿品种覆膜种植当年出苗率均在80%以上,均能达到开花期;利用层次分析法对6个品种的地上性状、根系性状及干草产量指标进行生产性能综合评价及排序,中草6号和中苜1号综合得分较高,表现出了较好的生产性能,可以优先作为大面积种植推广品种。In the saline region of Qaidam Basin, we conducted the adaptability of six alfalfa varieties resistant to salt and the production performance of the six alfalfa varieties was compared. The six varieties were Medicago sativa L. cv. ‘Sanditi＇, Medicago sativa L. cv. ‘Zhongmu No. 1＇, Medicago sativa L. cv. ‘Zhongmu No. 3＇, Medicago sativa L. cv. ‘Zhongcao No. 3’, Medicago sativa L. cv. ‘Zhongcao No. 6’, Medicago sativa L. cv. Longdong , respectively. The results showed that the germination rate of the six alfalfa varieties were all higher than 80% , and the blooming peri-od were completed for the six alfalfa varieties. The properties on aboveground , root character and dry forage yield of the six varieties were evaluated and contrasted by the method of Analytic Hierarchy Process （AHP） , it was concluded that Medicago sativa L. cv. ‘Zhongcao No. 6’ and Medicago sativa L. cv. ‘ Zhongmu No. 1 ’ were optimal in production character. Medicago sativa L. cv. ‘Zhongcao No. 6 、and Medicago sativa L. cv. ‘Zhongmu No. 1 ’ can be optimal planting varieties in saline region of Qaidam Basin.
