Study on the adaptability of Onobrychis viciaefolia cv. Gansu in alpine region of Gansu Province

Aimed to the situation of grassland degradation and lack of legume in alpine region, the adaptability of Onobrychis viciaefolia cv. Gansu was studied in the area with 3 050 m of altitude of Xiahe County, the alpine region of Gansu Province from 2004 to 2007 by measuring the growth periods, plant height，grass yield and overwintering rate. The results showed that the ripe seeds could be obtained, its grass yield and overwintering rate increased along with the growth time. It could be extended in alpine region as a high quality legume.
