摘　　要：研究旨在筛选适宜阴山沿麓地区生长的高产优质饲用型燕麦品种。试验分别在抽穗期和乳熟期测定6个燕麦品种的产量、品质相关指标,以熵值赋权DTOPSIS法对各品种饲草生产性能进行综合排序。结果显示,在阴山沿麓地区进行饲草燕麦生产收获时,乳熟期刈割产量及质量最佳。乌燕3号在阴山沿麓地区的生产性能综合评价相对接近度(Ci)值和产量最高,饲草生产性能最佳,可视为高产优质饲用燕麦品种。性状指标中,旗叶面积、干重叶茎比、粗蛋白(CP)含量、可溶性糖(SS)含量、株高、单株叶面积、鲜重叶茎比、鲜草产量的累计权重为82.34%,表明这8个指标在本研究的综合评价中影响最大。研究表明,经综合评价,乌燕3号适宜在阴山沿麓地区种植。The study was to screen out high yield and high quality forage oats suitable for growing in foothills of Yinshan Mountain.The yield and quality related indexes of six oat varieties were determined at heading stage and milk ripening stage,respectively.Forage performance of all varieties was ranked comprehensively by entropy weighted DTOPSIS method.The results showed that when the forage oat was harvested along the foothills of Yinshan Mountain,the yield and quality was the best when cutting at milk ripening stage.The C i value and yield of Wuyan No.3 were the highest in comprehensive evaluation of production performance in the foothills of Yinshan Mountain,and the forage performance was the best,so it could be regarded as a high-yield and high-quality forage oat variety.The cumulative weight of flag leaf area,dry weight leaf to stem ratio,CP content,SS content,plant height,leaf area per plant,fresh weight leaf to stem ratio and fresh grass yield was 82.34%,indicating that these eight indexes had the greatest influence in comprehensive evaluation of the study.The study indicates that Wuyan No.3 is suitable for planting along the foothills of Yinshan Mountain.
