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

A technology of Pinus tabulaeformis and woodland, which is applied in application, cultivation, agriculture, etc. It can solve the problems of high initial planting density, mixed tree species, poor resistance to diseases and insect pests, and slow natural regeneration, so as to improve the stability of the ecosystem and increase biodiversity. Sexuality, reasonable effect of restoring density

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 ser

Example Embodiment

[0036] Example

[0037] This embodiment relates to a method for promoting the restoration of severely degraded Pinus tabulaeformis forest land.

[0038] (1) Suitable area

[0039] It is used in areas suitable for the growth of Pinus tabulaeformis, and areas where the forest land has been seriously degraded into shrub land, shrub grassland, waste grassland or sparse woodland due to man-made destruction; and areas where enclosure measures are currently taken to restore forest vegetation.

[0040] (2) Artificial promotion measures for restoration of Pinus tabulaeformis forest land include:

[0041] a. Cultivate mother trees:

[0042] a1. Insufficiency in the non-Chinese pine parent tree or the Chinese pine parent tree (according to the parent tree distribution density formula n=S / [π(ɑh) 2 ]Calculation, the shrubland, shrubland, waste grassland or sparse woodland that is less than the calculated result shall be planted and arranged in the shape of "products" so that the parent tree row is pe...

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...
