摘　　要：为筛选出豫西地区春播条件下,适合种植的优质、高产、抗性强的苜蓿品种,对来自国内外的22个紫花苜蓿品种进行引种观察,测定了所有参试品种的株高、鲜干草产量、鲜干比、茎叶比、越冬率、营养成分(粗蛋白质、粗脂肪、粗灰分、中性洗涤纤维、酸性洗涤纤维)含量和相对饲用价值,采用多重比较进行数据分析,并采用灰色关联分析法对其生产性能和营养价值进行综合评价。结果表明:春播条件下,各参试品种鲜干草产量表现趋势:第3茬>第4茬>第2茬>第1茬;株高表现趋势:第3茬>第4茬>第2茬>第1茬;第3茬、第4茬鲜干比低于第1茬、第2茬。22个参试品种中WL440、劲能4.2、巨能601综合表现较好,适宜在豫西地区春季播种;沃苜1号、威神、猎人河这3个品种表现不理想,不建议在豫西地区春季种植推广。In order to select alfalfa varieties with high quality,high yield and strong resistance suitable for planting under the condition of spring sowing in western Henan,22 alfalfa varieties from home and abroad were introduced and observed,and the plant height,fresh hay yield,fresh dry ratio,stem-leaf ratio,overwintering rate,nutrient content(crude protein,crude fat,crude ash neutral detergent fiber,acid detergent fiber,etc.)and relative feeding value of all the tested varieties were determined.The results showed that under the condition of spring sowing,the performance trend of fresh hay yield of each tested variety was:the third crop>the fourth crop>the second crop>the first crop;The trend of plant height was:the third crop>the fourth crop>the second crop>the first crop;The fresh-dry ratio of the third and fourth crops was lower than that of the first and second crops.Among the 22 varieties tested,WL440,Jinneng 4.2 and Juneng 601 performed well and were suitable for spring sowing in western Henan.Womu No.1,Weishen and Hunter River were not satisfactory,so it was not recommended to plant and popularize them in spring in western Henan.
