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.
