为探索青藏高原天然草场高效利用管理模式，在甘肃省甘南藏族自治州进行冬春天然草场有机无机复合肥添加及刈割试验，结果表明;施肥后天然草地牧草粗蛋白含量显著高于不施肥草场。施肥后在天然草场牧草生长中期进行刈割能提高牧草生物量和粗蛋白含量。结果表明:施肥、刈割是青藏高原天然草场的有效利用方式。
Effect of Fertilization and Mowing on Biomass and Nutritional Quality of Alpine Natural Pasture
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.
