Abstract: In order to determine the suitable areas for oat(Avena sativa L.) planting,the effect of eco-environment in different planting areas on oat nutritive value and hay yield were studied from March to October in 2008 in Anding District,Dingxi(semi-arid area),Huajialing,Tongwei County(moist area) and Dachaigou,Tianzhu County(alpine area).The results show that the contents of crude protein and ADF in oat hay and grain changed significantly in these three areas,the eco-environments of different planting areas had significant effect(P<0.05) on oat nutritive value and yield.The highest values of average hay yield,average crude protein content and yield at grain-filling stage(8894.07 kg·hm-2 and 951.84 kg·hm-2,respectively) were observed in Huajialing.So Huajialing could be the most suitable place for oat hay production.Among 5 tested varieties,Ganyin No.1 and Longyan No.2 could be used for quality oat hay production due to the significantly higher average hay yield and crude protein yield than others(P<0.05);Baiyan No.7 could be used for seed production.

摘要: 从2008年3月10月在甘肃定西市安定区(半干旱区)、通渭县华家岭(二阴地区)和天祝县打柴沟(高寒区),通过研究不同种植环境对燕麦(Avena sativa L.)营养价值及干草产量的影响,以期确立燕麦适宜种植的区域。结果表明:灌浆期燕麦干草蛋白质、酸洗纤维、及成熟种子粗蛋白含量在3个区域变化显著,不同种植环境对燕麦营养价值及产量具有显著影响(P<0.05);灌浆期干草平均产量、干草平均粗蛋白产量均以华家岭为最高,分别为8894.07 kg·hm-2和951.84 kg·hm-2,因而华家岭最适宜燕麦生产;供试燕麦品种中,甘引1号和陇燕2号灌浆期干草平均产量和干草粗蛋白产量显著高于其他品种(P<0.05),可用来生产优质干草;白燕7号可用于种子生产。
