Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and examples, but not as a limitation of the present invention.

[0019] (1) set up a seedbed, the specific process is as follows:

[0020] ①Surface treatment: Pick up the gravel on the Gobi surface according to the following specifications. The specifications: a unit is 10m wide in the east-west direction and 300m long in the north-south direction, and the interval between the units is 5m, and the gravel is stacked in strips in the north-south direction on the untreated surface;

[0021] ② Lay multi-slit grass layer: Lay reeds with a minimum length of 1m, with a dry weight of 300g / ㎡, on the treated surface to form a multi-slit grass layer;

[0022] ③Gravel pressing: Utilize the raised gravel mentioned in step ①, such as figure 1 Be 0.2m in width, 0.1m in height, and 0.6m in spacing to form a gravel belt 1, lay it on the multi-slit grass layer 2 described in step ② to h...

Abstract

The invention relates to a gobi revegetation method and belongs to the field of environment treatment projects. The gobi revegetation method comprises the following main steps of (1) establishing a seedbed, which comprises the following sub-steps of a, treating earth surface; b, paving a multi-gap grass layer; c, pressing the grass by gravels; d, establishing the seedbed; (2) establishing vegetation, which comprises the following sub-steps of e, growing seedlings; f, treating seeds; g, sowing and planting; h, maintaining. By the gobi revegetation method, the roughness of the earth surface is increased, a sandy soil mixture carried in wind is intercepted to form the seedbed, plant seeds suitable for growing in gobi are supplemented, plant diversity is increased, soil fertility is improved, conditions suitable for living of soil microorganisms are created, positive succession of vegetational community is promoted, and gobi revegetation is realized finally.

Description

technical field [0001] The invention relates to vegetation reconstruction, in particular to a Gobi vegetation reconstruction method, which belongs to the field of environmental control engineering. Background technique [0002] The climate in the Gobi region is harsh, with low rainfall, large evaporation, frequent sandstorms, and sparse vegetation. Due to strong wind erosion, all the soil on the surface is blown away, and the gravel is spread all over, and the soil under the gravel is very hard. In this environment, plant seeds are hindered from fixing, unable to take root and germinate in large quantities, and it is difficult for plants to reproduce. However, frequent strong winds carry a large amount of soil, sand, and abundant super-xerophyte seeds, which in turn provide usable conditions for vegetation restoration. If the mixture carried by the wind can be retained on the surface to re-establish the soil layer and create a seedbed for the fixation and germination of see...
