| Abstract: | In this paper three execellent Gramineae pastures adaptability is analyzed by eamparing growth-development characteristic and forage yield in Qinghai province, Haibei, xihai district. Results shows: Three introduce varieties forage vegetation yield is weightier than local Elymus Nautans griseb. Third year, Bromus vegetation yield is 197316kg/hm~2, Elymus ahudmcus Turcz is 16457kg/hm~2, Timothy is 15754kg/hm2.Its shows strong resistance in the Xihai and plantable in the alpine region. |
