摘　　要：试验旨在探究不同燕麦品种在贵南地区的适应性。对12个燕麦品种的生产性能和品质进行比较分析,采用隶属函数分析法进行综合评价。结果显示,12个燕麦品种2022年的株高在117.89~169.78 cm之间,株高最高的品种是太阳神,2023年所有参试品种的株高均低于2022年。梦龙2022年和2023年的干草产量均最高,分别为25466.67 kg/hm^(2)、11873.33 kg/hm^(2),且该品种的鲜干比较低。甜燕麦的粗蛋白含量最高,为11.73%,显著高于其他品种(P<0.05),中性洗涤纤维含量最低,为44.23%,其营养价值较高,适口性较好。坝燕6号粗纤维含量为39.13%,显著高于其他品种(P<0.05),适口性较差。基于隶属函数综合评价结果发现,甜燕麦和梦龙的综合性能较佳。研究表明,甜燕麦和梦龙是适宜贵南地区种植和推广的优质燕麦品种。The experiment aimed to investigate the adaptability of different oat varieties in Guinan area.A comparative analysis was conducted on the production performance and quality of 12 oat varieties,and a comprehensive evaluation was performed using the membership function analysis method.The results showed that the plant height of the 12 oat varieties in 2022 ranged from 117.89 to 169.78 cm,with the highest plant height variety being Sun God.In 2023,the plant height of all tested varieties was lower than that in 2022.The dry hay yield of Menglong was the highest in both 2022 and 2023,reaching 25466.67 kg/hm²and 11873.33 kg/hm²,respectively.This variety had a relatively low fresh-to-dry ratio.Sweet oat had the highest crude protein content at 11.73%,significantly higher than other varieties(P<0.05),and the lowest neutral detergent fiber content at 44.23%,indicating higher nutritional value and better palatability.Bayan No.6 had the highest crude fiber content at 39.13%,significantly higher than other varieties(P<0.05),and poorer palatability.Based on the comprehensive evaluation results using the membership function,Sweet oat and Menglong were found to have better overall performance.The study concluded that Sweet oat and Menglong are high-quality oat varieties suitable for cultivation and promotion in the Guinan area.
