Embodiment Construction

[0028] Concrete steps of the present invention, condition are as follows:

[0029] 1) Synthesis of physical and chemical properties of soil

[0030] (1) Selection of raw materials

[0031] Select the white pulp soil with a humus content of more than 6% in the surface layer of about 20cm in the farmland; select the soil with a humus content of more than 12% in the meadow soil surface layer of about 20cm.

[0032] (2) Artificial soil synthesis

[0033] White pulp soil and meadow soil are paved in layers. First, 25cm of white pulp soil is laid, and 20cm of meadow soil is laid on it. (The layered structure of synthetic soil is close to that of mountain forest meadow soil).

[0034] (3) Soil acid adjustment

[0035] Since the raw materials of the synthetic soil are acidic, the synthetic subalpine forest meadow soil must be neutral or weakly alkaline. In order to successfully restore vegetation, it is necessary to adjust the acidity of acidic soil materials. Applying ...

Abstract

The invention belongs to the technical field of ecological environment engineering, and in particular relates to a restoration method of subalpine forest grass soil under the birch forest in Changbai Mountain. The invention achieves the purpose of restoring the subalpine forest grass soil under the Changbai Mountain betula forest through methods such as artificial soil synthesis and adjustment, soil seed bank construction, soil protection, and extermination of alien species in the soil. The method is simple, easy to popularize, and can obtain good ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of ecological environment engineering, and in particular relates to a subalpine forest meadow soil under the Changbai Mountain birch forest [0002] methods of soil restoration. Background technique [0003] Changbai Mountain is located in the southeastern part of Jilin Province, between 127°40'-128°16' east longitude and 41°35'-42°25' north latitude. It belongs to the temperate continental monsoon climate with obvious vertical climate zones. Due to the influence of the special geographical environment, it has formed a unique climate characteristic, which is characterized by dry and windy spring, warm and rainy summer, cool and foggy autumn, and cold and long winter. There are 4 types of soil vertically distributed from low to high altitude: 700-1100m above sea level is dark brown forest soil, 1100-1800m is distributed with brown coniferous soil (mountain brown forest soil), 1800-2000m is mountain forest ...
