Description

Technical Field

[0001] The invention relates to the technical field of grassland desertification restoration, and in particular to an ecological grassland desertification restoration and reseeding device. Background Art

[0002] Grassland is the foundation for building ecological barriers and developing animal husbandry. The degradation of grassland not only affects the sustainable development of animal husbandry, but also harms the ecological environment of grassland. At present, with the rapid growth of population in grassland pastoral areas and the rapid development of animal husbandry, it far exceeds the carrying capacity of grassland resources, resulting in the growth of grassland resources cannot meet the supply balance, resulting in local destruction of grasslands due to excessive human activities and overgrazing, and the recovery and renewal capacity of grassland resources has decreased, which can easily lead to grassland degradation and land hardening. Most of my country's grasslands belong to inland arid and semi-arid climates. The degraded grasslands and exposed surfaces have been eroded by wind for a long time, which will cause the evaporation of surface soil moisture, thereby causing the surface soil layer to become sandy, which is not conducive to plant growth. The sandy grassland can be repaired by reseeding grass seeds. When reseeding grass seeds on desertified grasslands, a rotary drill is used to sow grass seeds at fixed points, which is not convenient for controlling the sowing depth and sowing amount, and the manual control of the rotary drill depth results in low sowing efficiency; therefore, it does not meet the existing needs.
