摘　　要：为筛选出适宜青海省柴达木旱区种植的紫花苜蓿品种,于2020—2022年对引进的8个紫花苜蓿品种进行生产性能评比试验,并采用隶属函数法综合评价适合柴达木旱区种植的优质紫花苜蓿品种。两年试验结果表明:(1)在2021年,东苜2号的干草产量最高,为11373.44 kg·hm^(-2);在2022年,龙牧803的干草产量最高,为13485.54 kg·hm^(-2);(2)5909在两年的粗蛋白含量和相对饲喂价值均最高,分别为14.71%和126.01、14.07%和128.01,而酸性洗涤纤维含量均最低,分别为38.67%和36.90%;东苜2号两年的中性洗涤纤维含量均最低,分别为53.68%和51.35%;(3)基于隶属函数法对各紫花苜蓿品种生产性能的综合评价,东苜2号、龙牧803和5909综合性状表现较好,在柴达木干旱区适应性强、饲草产量及品质最优,建议在本地优先推广种植。To screen alfalfa cultivars suitable for planting in the Qaidam arid area in Qinghai Province,eight introduced alfalfa cultivars were subjected to a production performance evaluation test from 020 to 2022,and a comprehensive evaluation of high-quality alfalfa cultivars suitable for planting in the Qaidam arid area was carried out by using the method of the affiliation function.The results of the two-year experiment showed that:(1)In 2021,Dongmu No.2 had the highest hay yield of 11373.44 kg·hm^(-2),and in 2022,Longmu 803 had the highest hay yield of 13485.54 kg·hm^(-2).(2)5909 had the highest crude protein and relative feeding value in both years,with values of 14.71%and 126.01,14.07%and 128.01,respectively,while acid detergent fiber content was the lowest in both years,with values of 38.67%and 36.90%.Dongmu No.2 had the lowest neutral detergent fiber content in both years,with values of 53.68%and 51.35%.(3)Based on the comprehensive evaluation of the production performance of each alfalfa variety by the affiliation function method,Dongmu No.2,Longmu 803 and 5909 performed better in terms of comprehensive traits,with strong adaptability,optimal forage yield and quality in the Qaidam arid area,and it is recommended to give priority to local planting.
