Description

Technical Field

[0001] The invention relates to the technical field of sowing, and in particular to a degraded grassland no-tillage reseeding improvement device. Background Art

[0002] No-tillage reseeding is a key technology for restoring vegetation in degraded grasslands. Its significance is to improve the productivity and species diversity of degraded grasslands by reseeding suitable high-quality grass species without destroying or less destroying grassland vegetation. The Chinese patent application with application number 202122352422.3 discloses "a degraded grassland no-tillage reseeding improvement device, comprising a support seat, a traction seat is provided at the front end of the support seat, a storage bin is provided at the upper part of the support seat, and a plurality of flowmeters are provided at the bottom of the storage bin, and each flowmeter is connected by a transmission shaft; a reducer is provided on the support seat, and the support seat The rear end of the reseeding mechanism is equipped with a reseeding mechanism, and the rear end of the reseeding mechanism is equipped with a suppression mechanism. The first furrow opener is used to open furrows on the degraded grassland and sow drought-resistant grass seeds. At the same time, the weeds are cleaned by the first diversion roller to prevent weeds from accumulating at the front end of the first furrow opener and affecting the seed falling speed. Secondly, the depth of the furrow opener can be adjusted according to the actual soil moisture conditions; in addition, leguminous plants are sown under the action of the reseeding mechanism, and the suppression mechanism is used to suppress them after the sowing is completed. This scheme not only improves the quality of reseeding for ecological restoration of degraded grasslands, but is also suitable for no-till reseeding operations in large-scale degraded grasslands.

[0003] This technical solution only achieves the problem of repairing degraded grasslands through no-till reseeding. The physical and chemical properties of the soil on the degraded grassland will change. For example, the content of soil organic matter will decrease and the soil aggregate structure may be destroyed, causing the soil to become compact and thus easily form lumps. Soil agglomeration will reduce the air permeability and water permeability of the soil, limiting the growth space of seeds in the soil and hindering the expansion of the seed root system, making it difficult for the seeds to absorb enough nutrients and water. In addition, it is often difficult to cover the seeds evenly with the agglomerated soil. Summary of the invention
