Description
The "alpine grassland " account for about one third of the total grassland area in China. The site for this experiment was located at Tianzhu Tibetan Autonomous County, Gansu Province. It had an elevation of 2960m above sea level, an annual mean temperature of -0.1 °C, accumulated temperature(> 0°C) of 1316°C, precipitation of 391mm and evaporation capacity of 1611mm. There was no absolute frost-free period. Forages germinated at the end of April and withered at the beginning of September. The whole growing season lasted about 120 days. The local vegetation was dominated by a Stipa-Kobresia communty. Among the major species are Stipa purpurea, S. laxiflora, Festuca sp., Kobresia pygmaea, K. humilis, K. bellardii, Carex sp., Elymus nutans, Poa spp., Koeleria cristata , Pedicularis spp., Potentilla bifurca, P. multifurca, Gentiana spp. etc. The soil is of alpine meadow soil having loess as the parent material, moderate loamy and varying from slightly acid ( the northward mountain slopes ) to slightly alkaline ( the southward mountain slopes ).
