The invention relates to a plateau stony desertification region pasture planting method, which comprises the following steps of selecting pasture seeds; performing stirring and mixing with soil, dissolved fertilizers, water and crushed straws to form slurry, wherein the slurry is prepared from the following raw materials in parts by weight: 80 to 120 parts of water, 45 to 55 parts of soil, 3 to 7 parts of dissolved fertilizers, 1 to 4 parts of stalks and 0.8 to 2 parts of seeds; then, seeding the slurry into the plateau stony desertification region; completing the plateau stony desertification region pasture planting. The method provided by the invention has the advantages that the pasture seeds cannot be flushed away by rainwater; the fast moisture loss due to direct sunlight irradiation can be effectively prevented; the dissolved fertilizers provide the nutrition for the pasture seeds; the seed seeding survival rate is improved; the seed rooting and germination are ensured. The method provided by the invention has the advantages that the operation is simple; practicability is realized; the cost is low; the pasture fast and reliably grows; the plant coverage degree of the plateau stony desertification region is effectively improved; the environment is protected; the expansion of the stony desertification is prevented; the method is particularly suitable for ecological restoration and protection and use of the plateau stony desertification region.
