The experiment was conducted in Sangke alpine winter-spring pasture,Gannan Prefecture of Gansu province,with three treatments:unfertilization,fertilization without mowing,fertilization with mowing(mowed in mid-August).The results showed that fertilization improved the crude protein contents and biomass of forage significantly.Mowing in the growing stage of forage in the fertilized pasture not only improved forage yield but also increased the forage crude protein contents.The results showed that fertilization and mowing were feasible for the utilization of natural grassland on the Qinghai-Tibetan plateau.
