摘　　要：为筛选适宜干热河谷区种植的紫花苜蓿品种,于2016—2019年对11个参试紫花苜蓿品种的株高、干鲜比、鲜草产量、干草产量、粗蛋白、粗纤维、灰分、水分、粗脂肪、干物质、无氮浸出物、酸性洗涤纤维和中性洗涤纤维等指标进行测定,并采用灰色关联度法综合评价不同紫花苜蓿在干热河谷区的适应性。结果表明,3年平均每茬干草产量最高的品种为巨能995,达3.31 t/hm^(2);3年平均干鲜比最高的品种是WL525HQ,为27.58%;威斯顿的粗蛋白含量最高,达25.76%,中性洗涤纤维含量最低,为21.06%;维多利亚和WL440HQ的酸性洗涤纤维含量最低,均为24.14%。综合分析得出,WL525HQ、WL440HQ、巨能995等紫花苜蓿表现优异,适宜干热河谷地区推广种植。In order to screen Alfalfa sativa cultivars suitable for planting in dry-hot valley areas,the plant height,dry to fresh ratio,fresh grass yield,hay yield,crude protein,crude fiber,ash,water,crude fat,dry matter,nitrogen free extract,acid detergent fiber and neutral detergent fiber of 11 Alfalfa cultivars were measured from 2016 to 2019,and the adaptability of different Alfalfa cultivars in dry-hot valley areas were evaluated comprehensively by using the gray correlation degree method.The results showed that the variety with the highest average hay yield per crop for 3 years was Juneng 995,reaching 3.31 t/hm^(2);the variety with the highest average dry to fresh ratio in three years was WL525HQ,which was 27.58%;Weston had the highest crude protein content,reaching 25.76%,and Weston had the lowest neutral detergent fiber content,reaching 21.06%;the varieties Victoria and WL440HQ had the lowest acid washing fiber content,both of which were 24.14%.Through comprehensive analysis,it could be concluded that WL525HQ,WL440HQ,and Juneng 995 had excellent production performance,and were suitable for promoting and planting in dry-hot valley areas.
