摘要
本文通过对参试的6种燕麦在藏北高原适应性进行初步的探索研究，对其生育期、鲜草产量、株高、茎叶穗比等方面进行综合分析。研究结果表明：引进的六个燕麦品种都不能在藏北高原完成整个生育期，其中饲用燕麦亩产鲜草5389.36 kg，最低为青引1号，亩产鲜草1967.65㎏，相差3421.71㎏。加燕2号、领袖、燕王、原种16处于中等水平，分别为4135.4㎏、3868.6㎏、3868.6㎏、3535.1㎏；加燕2号在高海拔地区平均高度为117.33cm，其次是饲用燕麦113.17cm，叶占比燕王最高为32.07%，其次为饲用燕麦29%，综合考虑，饲用燕麦在藏北高原种植表现出较好经济效益。

Abstract
Based on the preliminary research on the adaptability of the six oats tested in the northern Tibetan plateau, the growth period, fresh grass yield, plant height, stem leaf ear ratio and other aspects were comprehensively analyzed. The results showed that the six introduced oat varieties could not complete the whole growth period in the northern Tibetan plateau. Among them, the forage oats produced 5389.36 kg of fresh grass per mu, the lowest was Qingyin No. 1, and the yield of fresh grass per mu was 1967.65 kg, with a difference of 3421.71 kg. Jiayan 2, Leader, Yanwang and original 16 are at the middle level, respectively 4135.4 kg, 3868.6 kg, 3868.6 kg and 3535.1 kg; The average height of Jiayan 2 in high altitude areas is 117.33cm, followed by feeding oats of 113.17cm, with the highest proportion of leaves to Yanwang being 32.07%, followed by feeding oats of 29%. Overall, the planting of feeding oats in the northern Tibetan plateau has shown good economic benefits.
