摘　　要：In Guizhou Province, the area of rocky desertification land is 3.023 8 million hm^2, accounting for 17.16% of total area of land in the province. Rocky desertification is the most important ecological problem that restricts the economic and social development in Guizhou, so the primary task of ecological construction in Guizhou Province is to curb rocky desertification. How to effectively, efficiently and persistently use rocky desertification land is not only the key to the improvement of ecological environment, but also an urgent problem solved for local people's survival and anti-poverty. Due to having developed roots, growing fast, high yield of grass, strong resistance to drought, and high regeneration capacity, Pennisetum sinese Roxb has become a new method to control rocky desertification. How to use P. sinese Roxb efficiently becomes the key to the ecological control of rocky desertification by P. sinese Roxb. In this study, the ecological agriculture development model of "P. sinese Roxb-rocky desertification control-edible mushrooms" was studied, and the effect of cultivating Pleurotus eryngii with P. sinese Roxb in rocky desertification land was analyzed. Moreover, an outlook for the application of P. sinese Roxb in rocky desertification areas of Guizhou was given.In Guizhou Province, the area of rocky desertification land is 3.023 8 million hm2, accounting for 17.16% of total area of land in the province.
