摘　　要：为筛选适宜达拉特旗地区种植的饲用燕麦(Avena sativa)品种,对22个燕麦品种的生产性能和营养价值进行比较,结果表明,燕麦品种株高为50.90~80.07cm,鲜草产量为5562.67~14900.67kg/hm^2,干草产量为2393.93~5812.10kg/hm^2,品种间存在显著差异(P<0.05)。牧王和魅力燕麦的叶茎比显著高于其他品种(P<0.05),各燕麦品种的粗蛋白、粗脂肪、中性洗涤纤维和酸性洗涤纤维含量变化范围分别为7.95%~12.08%,5.28%~6.74%,47.92%~58.82%和27.60%~36.46%;贝勒和莫妮达燕麦的饲料相对值显著高于其他品种(P<0.05)。运用隶属函数分析法评价了22个燕麦品种的生产性能,甜燕1号、牧王、太阳神综合评价数值较高,更适合达拉特旗地区种植。To select suitable forage oat(Avena sativa)varieties for planting in Dalad Qi,the production performance and nutritional value of 22 oat varieties were assessed.Results showed that the plant height of oat varieties was 50.90 to 80.07cm,the fresh yield was 5562.67 to 14900.67kg/hm^2,and the hay yield was 2393.93 to 5812.10kg/hm^2.There were significant differences among the varieties(P<0.05).The leaf stem ratios of Haymaker and Charisma were significantly higher than that of the other varieties(P<0.05).The contents of crude protein(CP),crude fat(EE),neutral detergent fiber(NDF)and acid detergent fiber(ADF)of each oat variety were 7.95%~12.08%,5.28%~6.74%,47.92%~58.82% and 27.60%~36.46%,respectively.The relative feeding values(RFV)of Monida and Baler were significantly higher than those of other varieties(P<0.05).The production performances of 22 oat varieties were evaluated by the membership function analysis method.The comprehensive evaluation value of Sweety,Haymaker and Titan were higher,which were more suitable for promotion in Dalad Qi.
