Description
Technical Field
The invention belongs to the technical field of original ecological restoration of degenerated alpine grasses, and particularly relates to a restoration method of degenerated alpine grasses of a Qinghai-Tibet plateau.
Background
Alpine Steppe (Alpine Steppe) is a plant community which is influenced by cold and drought climates in high-altitude areas for a long time and is formed by breeding of cold-resistant and drought-resistant perennial dense-clumped grasses, rhizome-type sedge and cushion-shaped shrub plants. The alpine grassland is one of the most main grassland types in the Qinghai-Tibet plateau area of China.
The Qinghai-Tibet plateau is a fragile ecosystem with global significance. As one of the important pasturing areas in China, the grassland area is wide and accounts for about 50.9 percent of the total area of the Qinghai-Tibet plateau. The complex biodiversity and unique geographic environment and cultural characteristics provide guarantees for local life and economic development. However, in recent years, due to unreasonable grazing regimes, artificial factors such as excessive reclamation, and changes in natural climate (drought, low temperature), alpine grasses which are fragile originally are degraded to various degrees. The grassland in the alpine pasturing area is degraded by 39.64 percent, and the degraded area of the grassland is expanded by 3 to 5 percent each year. The diversity of grassland is lost, the stability is reduced, the productivity is reduced, the vegetation is difficult to recover, the quality of the pasture is deteriorated, and the soil is desertified. Therefore, how to reasonably and effectively repair the degenerated high-cold grassland is an urgent problem to be solved.
Mixed sowing of grasslands is an effective measure for recovering deteriorated grasslands, and is researched at home and abroad. The mixed grassland seeding is to seed grasses on the basis of the original natural grasslands so as to increase the grassland coverage and the productivity of grasslands and improve the quality of the grasses, thereby achieving the effect of restoring the grassland ecology.
In the prior art, the mixed sowing mode of leguminous plants and gramineous plants is most applied. Because leguminous forage germplasm resources with strong adaptability and reasonable management measures are lacked in the Qinghai-Tibet plateau, the reseeded leguminous forage has weak competitiveness, low survival rate and difficult diffusion, thereby being difficult to popularize in a large area.
