中文摘要	为了确定不同紫花苜蓿(Medicago sativa)品种在半干旱地区生产性能的大小和营养价值的高低,在兰州国家区域试验站,连续两年对12个紫花苜蓿品种的生产性能进行测定分析,采用灰色系统关联度理论综合评价分析了不同品种紫花苜蓿的粗蛋白、粗脂肪、粗灰分、粗纤维、含水量、无氮浸出物、钙、磷含量8项营养指标。结果表明,不同品种苜蓿在不同茬次时株高和干草产量均存在显著性差异(P<0.05),两年内随着收割茬数的增加,株高和干草产量不断减小,中苜3号、甘农3号、甘农5号、中苜5号和康赛的植株较高,甘农5号、甘农3号和阿迪娜的干草产量较高;不同紫花苜蓿品种营养品质也存在差异,其中甘农5号、中苜3号最优,甘农3号、中苜5号、康赛次之。从生产性能和营养价值综合考虑,甘农5号、中苜3号、甘农3号、中苜5号和康赛生产性能优异、营养价值高,综合性状突出,可以作为黄土高原半干旱地区大面积推广种植的紫花苜蓿品种。
英文摘要	In order to determine the yield and nutritional value of different alfalfa cultivars in semi-arid areas, we evaluated 12 alfalfa(Medicago sativa L.)varieties in the National Regional Test Station in Lanzhou using a completely randomized block design.According to the theory of grey system correlation degree,the comprehensive evaluation of eight nutritional indexes(crude protein,crude fat,crude ash,crude fiber,crude fiber, water content,nitrogen free extract,calcium,and phosphorus)of different alfalfa cultivars was carried out. The results showed that the plant height and hay yield were significantly different among different alfalfa varieties( P<0.05).During the two years of study,hay yield decreased from the first to the third harvest.The Average heights of Zhongmu No.3,Gannong No.3,Gannong No.5,Zhongmu No.5,and Kangsai were higher than that of the other varieties tested.Hay yield of Gannong 5,Gannong 3,and Adina were higher than that of the other varieties tested.There were additional differences in the nutritional quality of different alfalfa varieties and the quality of Gannong No.5 and Zhongmu No.3 were the best,followed by that of Gannong No.3,Zhongmu No.5,and Kang Sai.Based on the production performance and nutritional value,Gannong No.5,Zhongmu No.3,Gannong No.3,Zhongmu No.5,and Kangsai had excellent production performance,high nutritional value,and outstanding comprehensive traits,and these five cultivars are suitable for cultivation in the alfalfa hay production areas in the semi-arid regions of the Loess Plateau.
