[0002] The recolonization of constructive species is an important goal of functional restoration of degraded grasslands. Leymus chinensis is one of the construction species of typical grasslands and meadow steppes in China. Due to the low germination rate of Leymus chinensis and the poor nutrient content of degraded grassland, traditional supplementary sowing and aerial sowing techniques are not only unfavorable for seedling management, but also difficult to meet the nutrient requirements of Leymus chinensis colonization and propagation. Therefore, the success rate of Leymus chinensis colonization not tall. Existing techniques for colonization of Leymus chinensis in degraded grasslands include no-tillage supplementary sowing, aerial sowing, etc. The objective disadvantages of these tech...
