摘　　要：为筛选适宜鄂尔多斯地区种植的紫花苜蓿品种,于2012~2016年在内蒙古鄂尔多斯中国农业科学院草原研究所试验站对16个国内外紫花苜蓿品种生产性能进行比较。结果显示:16个苜蓿品种年均干草产量差异显著(P<0.05),4年干草总产量位居前三的品种是康赛、新疆大叶和肇东,分别为54193.2kg/hm^(2)、53394.9kg/hm^(2)和53320.0kg/hm^(2);各茬次产量与年产量相关分析表明,第一茬产量与年产量的相关系数最高;综合分析表明,肇东、新疆大叶、康赛、巨人和WL168HQ这5个品种适应性和丰产性等整体优于其他品种,适宜在鄂尔多斯地区推广种植。In order to select suitable alfalfa varieties for planting in Ordos region,the productivity of 16 domestic and foreign alfalfa varieties was analyzed in 2012~2016 at the Experimental Station of Grassland Research Institute,Chinese Academy of Agricultural Sciences,Ordos,Inner Mongolia.The results showed that the hay yields of 16 alfalfa varieties were significantly different in each year(P<0.05).The top three varieties in productivity in the four-year trial were Kangsai,Xinjiang Daye and Zhaodong,which were 54193.2kg/hm^(2),53394.9kg/hm^(2)and 53320.0kg/hm^(2)respectively.In the correlation analysis between the yield of each cutting crop and the annual yield,the yield of first cutting crop had the highest correlation with the annual yield.Comprehensive analysis showed that Zhaodong,Xinjiang Daye,Kangsai,Giant and WL16HQ had strong adaptability and good production performance,which were suitable for planting in Ordos area.
