Abstract. Most of the grasslands in China are distributed in the arid and semi-arid areas in the north of China. The subsurface soil of the grassland is seriously hardened, and the soil-root complex structure is not aerated and impervious to water, which inhibits the growth of forage grass. Mechanized improvement can better realize grassland ecological restoration. By comparing the domestic and foreign grassland seeding improvement machinery and equipment, the structure characteristics of typical grassland seeding improvement machinery were analyzed, and the application of legumes and grasses mixed seeding technology was analyzed, so as to provide possible ideas for the follow-up research on grassland improvement machinery.
