The plots need to be treated after enclosure, and the treatment method is spreading an organic fertilizer first, and then gently raking the grassland with a raking depth of 3-5 cm； seed proportioning is mixing fast-establishment and slow-establishment grass seeds according to a certain proportion to achieve the purpose of improving biodiversity of the grassland； seed treatment is mixing the grass seeds that have been soaked in warm water with a seed-dressing agent to make the seeds have a higher germination rate； sowing is carried out in a manner of seeder dibbling or manual sowing； and in addition to topdressing of fertilizers, field management also requires spraying a herbicide while deploying a poison bait, which is beneficial for ensuring the normal growth of forage. By adopting the method of the present invention, the soil environment of the alpine grassland can be obviously improved, such that the alpine grassland is beneficial for the free growth of forage and can effectively solve the technical problem of difficult restoration of the degraded alpine grassland.1/1 7 6 504~ 0 Control Resowing FIG1 400 350 300 1250 cn 200 0150 100 50 0 Control Resowing FIG2 90 80 70 60 -0 40 30 ~20 0 10 Control Resowing FIG3
