摘要：

在陇西二阴山区,对13种燕麦(Avena sativa)的农艺性状及营养价值进行比较研究,结果表明:选用的13种燕麦品种种子均能饱满成熟,其中,株高低于100 cm有5种;101～110 cm有5种;111 cm以上有3种。‘青海甜燕麦’(16100 kg·hm-2)和‘冀引1号’(15600 kg·hm-2)的干草产量显著高于其他品种(P<0.01),‘巴彦3号’(4500 kg·hm-2)干草产量最低。成熟期‘白燕2号’、‘冀引1号’NDF高于其他品种。‘青永久307’ADF最高,‘黄燕麦’ADF最低。‘TCO燕麦’CP最高,‘青引1号’最低。综合分析表明,‘青海甜燕麦’、‘青引1号’、‘欧洲316’、‘青永久307’是甘肃陇西县二阴山区建植燕麦草地的首选品种。

Abstract:

A studye on agronomic traits and nutritional values of 13 oat varieties was conducted in arid and emiarid region of Longxi. The results showed that all the tested varieties could mature in the research region. There were five oat varieties whose height was below 100 cm, five oat varieties height was range from 101 cm to 110 cm, and three oat varieties height was above 111cm. The hay yield of ‘Qinghaitian’ (16100 kg·hm-2) and ‘Jiyin No.1’ (15600 kg·hm-2) were significantly higher than the other varieties (P<0.01), while ‘Bayan No. 3’ was the lowest one (4500 kg·hm-2). The NDF content of ‘Baiyan No. 2’ and ‘Jiyin No. 1’ were significantly higher than the other varieties (P<0.05); The ADF content of ‘Qingyongjiu No. 307’ was higher (37%) than other varieties, while ‘Huang’ is the lowest (28%); The CP content of ‘TCO’ was the highest (7.74%); while ‘Qingyin No.1’ is the lowest (4.74 %). Among 13 tested varieties, the ‘Qinghaitian’, ‘Qingyin No. 1’, ‘Europe No. 316’ and ‘Qingyongjiu No. 307’ were regarded as the first choice of oats varieties, which could be used for establishing cultivated meadow of high-quality oats in arid and emiarid region of Longxi County, Gansu Province.
