In recent years, grassland management has shifted from production-oriented to ecological priority, and the National Forestry and Grassland Administration has restored 600 million mu of grassland in total.

[0003] No-till reseeding refers to the technology of using no-tillage method to improve the ecological quality of grassland and enhance grassland productivity and species diversity by reseeding high-quality grass seeds without destroying or less destroying native vegetation. The main measure for construction site restoration and degraded grassland restoration is no-till reseeding. Reseeding native grass seeds has two major advantages. First, it avoids the risk of biological invasion. Second, the growing climate conditions are consistent with the reseeding environment conditions, and the survival rate of grass seeds is high. However, it is difficult to purchase native grass seeds on the market. Manual collection of grass seeds is slow and low in yield, which is difficult to meet the restoration needs. The relevant collection machinery on the market is difficult to operate in mountainous areas, meadows and other places. However, during the use of existing manual collection devices, the grass itself will be pulled out of the ground, destroying the native vegetation. Utility Model Content
