摘　　要：为筛选出适宜在凉山州中低海拔地区种植的优质饲用燕麦(Avenasativa)品种,本研究选用15份饲用燕麦为供试材料,对其饲草产量、农艺性状和营养品质等指标进行综合评价。结果表明,‘牧乐思’的鲜草产量最高,为48310.81 kg·hm^(-2);‘太阳神’的干草产量最高,为16058.62 kg·hm^(-2)。‘优牧一号’和‘牧乐思’的干鲜比最小,‘爱沃256’的茎叶比最小。鲜草产量和茎叶比呈显著负相关关系(P<0.05),干鲜比和干草产量显著正相关关系(P<0.05)。‘优牧一号’的粗蛋白含量最高,为13.08%;木质素含量最低为3.25%,总可消化养分含量最高为56.33%,较其他品种差异显著(P<0.05)。‘楷模’的酸性洗涤纤维和中性洗涤纤维含量显著低于其他供试材料(P<0.05),且其相对饲喂价值最高;‘优牧一号’的相对牧草质量均显著高于其他供试材料(P<0.05)。通过隶属函数和TOPSIS综合分析,表现最优的分别为‘牧乐思’‘麦迪逊’和‘太阳神’,可作为优良饲用燕麦品种在凉山州推广种植。To screen out high-quality forage oat(Avena sativa)varieties suitable for planting in middle and low-altitude areas of the Liangshan Prefecture,we selected 15 forage oat varieties as experimental materials to comprehensively evaluate forage yield,agronomics traits,and nutritional quality of the tested varieties.The findings indicate that‘Molasses’achieves the highest fresh grass yield at 48310.81 kg·ha^(-1),whereas‘Titan’records the highest dry grass yield at 16058.62 kg·ha^(-1).‘YoumuⅠ’and‘Molasses’had the smallest dry/fresh ratio,and‘Everleaf 256’had the smallest stem/leaf ratio.The dry/fresh ratio was positively correlated with hay yield(P<0.05),while the fresh grass yield was negatively correlated with the stem/leaf ratio(P<0.05).The crude protein content of‘YoumuⅠ’was the highest(13.08%),lignin content was the lowest(3.25%),and total digestible nutrients content was the highest(56.33%),which was significantly different from other varieties(P<0.05).The acid detergent fiber and neutral detergent fiber contents of the‘Model’were significantly lower than those of other tested materials,indicating its highest relative feeding value(P<0.05).The relative forage quality of‘YoumuⅠ’surpasses significantly that of other tested materials(P<0.05).A comprehensive analysis of membership function and TOPSIS(technique for order preference by similarity to an ideal solution)showed that‘Molasses’‘Madison’and‘Titan’performed the best and could be used as excellent forage oat varieties in local cultivation.
