Method for prompting seriously-degraded Chinese pine forest land to restore

Abstract

The invention discloses a method for prompting seriously-degraded Chinese pine forest land to restore. The method is a method close to natural restoration and includes that for shrub land, shrub-grassland, waste grassland or sparse wood land formed by serious degradation of forest land, on the premise of closed cultivation, Chinese pine seed trees are cultivated, and part artificial hole-shaped land preparation and belt-shaped cutting irrigation as well as subsequent seedling fostering and management are performed to promote the shrub land, the shrub-grass land, the waste grassland or the sparse wood land to restore Chinese pine forest land step by step. By the method, seed tree resources can be utilized fully, natural seed scattering can be realized depending on the seed trees, transplanting and cultivating of sprouting Chinese pine seedlings are enhanced, and planting range can be expanded step by step. The method has the advantages of being reasonable in restoration density, low inafforestation cost, easy in forming an arbor-shrub-grass compound structure and capable of improving biodiversity and ecological system stability.

Description

technical field [0001] The invention relates to the technical field of Chinese pine forest restoration, in particular to a method for promoting the restoration of severely degraded Chinese pine forest land. Background technique [0002] Pinus tabulaeformis is a coniferous evergreen tree in the family Pinaceae, with shallow roots, light-loving, drought-resistant, barren-resistant, and wind-resistant, and has strong adaptability and stress resistance. It is one of the main afforestation tree species in the mountains of northern Hebei. Since the 1950s, a large number of pure Chinese pine forests have been planted through artificial afforestation in northern Hebei. Due to the high initial planting density and the lack of mixed tree species, etc., the forest land biodiversity is low, natural regeneration is difficult, and the growth of trees is slow. A series of problems such as poor resistance to diseases and insect pests seriously affect the stability and self-sustainment of th...

Problems solved by technology

Since the 1950s, a large number of pure Chinese pine forests have been planted through artificial afforestation in northern Hebei. Due to the high initial planting density and the lack of mixed tree species, etc., the forest land biodiversity is low, natural regeneration is difficult, and the growth of trees is slow. A series of problems, such as poor resistance to diseases and insect pests, seriously affect the stability and self-sustainment of the ecosystem, and affect the effective performance of ecological service functions.

Therefore, in areas suitable for Pinus tabulaeformis in northern Hebei, where the forest land has been severely degraded into shrubland, shrubland, grassland, or sparse forest due to human destruction, it is necessary to relocate the vegetation to restore the Pinus tabulaeformis forestland, but enclosing the shrubland, shrubland, etc. The natural renewal of grassland or barren grassland is slow, and artificial afforestation is not only costly, but also prone to follow-up series of ecological problems
