摘　　要：试验旨在筛选出适宜在三江源地区种植的燕麦饲草品种。试验对三江源地区引进种植的8个燕麦品种的农艺性状、干草产量和营养物质含量进行测定,并进行隶属函数综合评价。结果显示,青引2号和甜燕麦的株高、干草产量显著高于其他燕麦品种,且甜燕麦干草产量高达7380.00 kg/hm^(2),较青甜2号显著增加了50.6%(P<0.05)。白燕7号、青引2号和甜燕麦的茎叶比较低,分别为2.83、3.33和3.48。青引2号和甜燕麦的粗蛋白、粗脂肪含量均显著高于其他燕麦品种(P<0.05),其中青引2号粗蛋白含量高达14.96%,甜燕麦粗脂肪含量高达8.94%。青引2号和甜燕麦的隶属函数值分别为0.81和0.95,属优,为Ⅰ级。研究表明,青引2号和甜燕麦各项指标均高于其他品种,更适宜在三江源区的果洛地区推广种植。The experiment aimed to screen out oat forage varieties suitable for planting in Sanjiangyuan region.The experiment measured the agronomic traits,hay yield and nutrient content of eight oat varieties introduced for cultivation in Sanjiangyuan region,and carried out a comprehensive evaluation of the affiliation function.The results showed that the plant height and hay yield of Qingyin No.2 and sweet oat were significantly higher than those of other oat varieties.The hay yield of sweet oat was 7380.00 kg/hm^(2),which was significantly increased by 50.6%compared with Qingtian No.2(P<0.05).Baiyan No.7,Qingyin No.2,and sweet oat have relatively low stem-to-leaf ratios,which were 2.83,3.33,and 3.48 respectively.The contents of crude protein and crude fat of Qingyin No.2 and sweet oat were significantly higher than those of other oat varieties(P<0.05).The crude protein content of Qingyin No.2 and crude fat content of sweet oat were 14.96%and 8.94%respectively.The membership function values of Qingyin No.2 and sweet oat were 0.81 and 0.95,respectively,which were excellent and gradedⅠ.The study indicates that the Qingyin No.2 and sweet oat have superior performance in various metrics compared to other varieties,making them more suitable for promotion and cultivation in the Guoluo area of the Sanjiangyuan region.
