摘　　要：为筛选适宜在甘肃河西灌区种植的国内紫花苜蓿品种,2018—2021年对9个国内紫花苜蓿品种进行了引种试验,对其干草产量、草产量相关性状及干草营养品质进行了连续3年的测定。结果表明,9个苜蓿品种均能在河西地区完成整个生长周期,生育期差异不明显;中苜1号、甘农3号的干草产量较高,分别为22 519.25和22 426.72kg/hm^(2),中苜7号、中兰2号的粗蛋白含量较高,分别为20.63%和20.04%。灰色关联度评价结果表明,中苜1号、甘农3号、中苜3号、草原3号紫花苜蓿的综合表现优异,可以在河西灌区引种推广。In order to select suitable domestic alfalfa varieties for planting in the Hexi irrigation district of Gansu,an introduction experiment was conducted on 9 domestic alfalfa varieties from 2018 to 2021,and their hay yield,grass yield related traits,and nutritional quality of hay were measured for three consecutive years.The results showed that all 9 alfalfa varieties were able to complete the entire growth cycle in the Hexi region,with no significant differences in growth stages.The hay yields of Zhongmu No.1 and Gannong No.3 were relatively high,at 22519.25 and 22426.72 kg/hm^(2),respectively.The crude protein contents of Zhongmu No.7 and Zhonglan No.2 were relatively high,at 20.63%and 20.04%,respectively.The grey correlation degree evaluation results indicated that the comprehensive performance of Zhongmu No.1,Gannong No.3,Zhongmu No.3 and Caoyuan No.3 alfalfa were excellent,and could be introduced and promoted in the Hexi irrigation district.
