Moderate degeneration subalpine flat dam meadow recovery technology

Abstract

The invention discloses a moderate degeneration subalpine flat dam meadow recovery technology capable of effectively enabling a moderate degeneration meadow to be recovered. The moderate degeneration subalpine flat dam meadow recovery technology includes the following steps: firstly, carrying out enclosure on the degeneration meadow, enabling the enclosure to be lasted for at least one year, forbidding pasturing during the enclosure period, after pasture turns green, oversowing pasture seeds and fertilizing the degeneration meadow, and in the degeneration meadow, sowing the following pasture seeds: 1.3-1.7 kilograms per mu of elymus sibiricus, 1.3-1.7 kilograms per mu of lyme grass, 0.6-1.0 kilogram per mu of bluegrass and 0.6-1.0 kilogram per mu of red fescue. According to the moderate degeneration subalpine flat dam meadow recovery technology, the majority of the moderate degeneration meadow can be recovered ordinarily within one year, animals can be conservatively grazed after soil is frozen in winter from the second year, and after the fifth year, the moderate degeneration meadow can be completely recovered. The moderate degeneration subalpine flat dam meadow recovery technology is suitable for being popularized and applied in the pratacultural field.

Description

technical field [0001] The invention relates to the field of herbaceous science, in particular to a restoration technology for moderately degraded subalpine flat dam meadows. Background technique [0002] Subalpine meadow is a type of alpine meadow. The alpine meadow is a type of meadow adapted to the alpine habitat. It is a meadow community with cold-tolerant, dense clusters of short-rhizome subterranean Kobresia subterranean plants, sedges, grasses, and forbs. It is most widely distributed in the high mountains in western my country and the eastern Qinghai-Tibet Plateau, and it also exists in the Qinling Mountains, Xiaowutai Mountains and Northwest Yunnan Mountains. Due to the variety of species, the growth is dense and the coverage is large. Among them, the most typical one is the wormwood meadow, with more than 10 species of colonies, distributed at an altitude of 4000-5000m; the alpine meadow dominated by forbs, distributed at a slightly lower altitude, and has a gorg...

Problems solved by technology

At present, there is no effective measure for how to restore degraded meadows. Most of them apply some fertilizers in degraded meadows to promote the growth of pastures. For moderately degraded and severely degraded meadows, the effect is not obvious. If meadow degradation is not effectively suppressed and restored, the meadow will degenerate into a desert after a long time, causing great damage to the environment.
