Microbes require a relatively long time to recover in natural succession restoration of degraded grassland ecosystems

Using natural succession to restore degraded grassland is mainly achieved by self-adjusting the structure and relationship of the internal components of grassland ecosystems. Microorganisms play an important role in the restoration of grassland ecosystems; however, there is no systematic research su...
