摘要： 对科尔沁沙地进行4个饲用燕麦(Avena satiua)品种产量特性研究，以期筛选出适合科尔沁沙地种植的优良饲用燕麦品种。结果表明：乳熟期收获的饲草产量显著高于抽穗期(P＜0.05)；抽穗期饲用燕麦干草产量排序‘梦龙’＞‘甜燕1号’＞‘贝勒’＞‘牧马人’；乳熟期饲用燕麦干草产量排序‘甜燕1号’＞‘梦龙’＞‘贝勒’＞‘牧马人’；抽穗期‘梦龙’品种的株高显著高于其他3个品种(P＜0.05)；‘甜燕1号’茎叶比与其他3品种比较最低，且差异显著(P＜0.05)。综合评估‘甜燕1号’和‘梦龙’可作为科尔沁沙地推广种植的饲用燕麦品种。

Abstract: The paper aims to screen good forage oat varieties which are suitable for planting in Horqin sandy land, the authors studied yield characteristics of 4 oat varieties. The results showed that: the forage yield harvested at milk stage was significantly higher than that at heading stage (P<0.05); In heading stage, the hay yield of forage oat ranged from more to less,respectively,‘Magnum’,‘Sweet Yan No.1’,‘Beller’,‘Wrangler’;In milk stage,the hay yield of forage oat ranged from more to less,respectively,‘Sweet Yan No.1’,‘Magnum’,‘Beller’,‘Wrangler’; The height of ‘Magnum’ was significantly higher than that of other 3 varieties at heading stage (P<0.05); The stem-leaf ratio of ‘Sweet Yan No.1’ was lowest than other 3 varieties at heading stage which had significant differences (P<0.05). The conclusion is ‘Sweet Yan No.1’ and ‘Magnum’ can be forage oat varieties for planting and promoting in Horqin Sandy land.
