Embodiment 1

[0030] Example 1 A soil-activated fiber material for slag and gravel slope vegetation restoration

[0031] The raw material composition of the soil activated fiber material is as follows:

[0032] The soil activation fiber material comprises the following components by weight: 5 parts of short wood fiber, 4 parts of peat, 1 part of compound fertilizer, 0.01 part of binder, 0.01 part of water-retaining agent, 90 parts of guest soil and 5 parts of anti-scouring material.

[0033] The short wood fibers are bark or log fibers with a length of 10mm and a diameter controlled within 0.2mm. The fiber is mainly the elongated fiber structure formed by pyrolysis of bark, logs or crop stalks, and short fibers are formed by shearing.

[0034] The foreign soil materials are mainly local natural soil materials, and the local high-quality cultivated soil is preferred. If there is no local mountain weathered soil or forest soil, local mountain weathered soil or forest soil can also be used. ...

Embodiment 2

[0045] Embodiment 2 A kind of slag, crushed stone texture slope vegetation restoration method

[0046] The restoration method is aimed at slopes with slag and gravel texture without soil on the surface or with weathered soil on the surface.

[0047] 1. Seed treatment

[0048] Seeds for spraying need to be soaked in hot water at 30-40°C for 24 hours in advance to increase the germination rate.

[0049] Choose the seed scheme combining grass and shrubs. For herb seeds, use one or a combination of ryegrass, fescue, bluegrass, and bermudagrass, and for shrub seeds, use one of Robinia, Amorpha, Leucaena, and Shadawang. one or a combination of several.

[0050] 2. Treatment before spraying

[0051] (1) Slope cleaning: Before clearing the slope, determine the scope of the slope operation, and set out the line at the operation boundary, and then remove the weeds, gravel, floating soil and other sundries on the slope surface that affect the construction, and the cleaned side slope ...

Abstract

The invention provides a method for restoring vegetation on slag and gravel slopes. The restoration method includes spraying the inner layer, applying a thin soil layer, and spraying the surface; the inner layer spraying: through air pressure or irrigation water pressure Fill the planting layer spraying material into the gaps of the slag and gravel texture slope, the filling depth is 10-50cm; the surface spraying: spraying a layer of anti-scour material. By adopting the method of the invention, the sprayed material can infiltrate and fill the cracks of gravel or slag, and the filling depth reaches 10-50 cm; the formation of honeycomb effect is prevented, and the water and soil loss rate is reduced by more than 90%.

Description

technical field [0001] The invention relates to a method for restoring vegetation on slag and gravel slopes, and belongs to the technical field of environmental protection. Background technique [0002] Slag and gravel slopes refer to the surface slopes of slag piles or stone piles formed by the accumulation of slag or crushed stones. The repair of this kind of slope has always been a difficult problem in wound repair. Because there are large cavities in the rock pile and there is no soil and other materials to fill them, the vegetation root system cannot absorb nutrients and water. The current basic method is to cover the slope with soil, foreign soil, etc. to provide growth space for plants. However, with the traditional way of covering soil and sowing, because the gravel and slag piles are filled with gaps, a strong honeycomb effect is formed, resulting in surface water and soil erosion. At the same time, the adhesion between the overburden layer and the pile body is po...
