preparation example Construction

[0044] Compound microbial agents include anti-pest and insect bacteria agents, purifying bacteria agents, and nitrogen-fixing bacteria agents mixed together. For example, the anti-pathogenic bacteria agent includes at least one of Bacillus polymyxa, Bacillus cereus, Trichoderma viride, and Paecilomyces lilacinus. The preparation method of the anti-pest bacterial agent includes: mixing various bacterial liquids with sterilized diatomaceous earth (for example, the particle size of sterilized diatomaceous earth is 0.1mm-0.4mm) under aseptic conditions, so as to kill The bacterial diatomaceous earth is moist, and kept loose and not agglomerated. Then, the sterilized diatomaceous earth is air-dried in a cool place to prepare an anti-fungal agent. The anti-fungal agent needs to be stored at low temperature. The anti-fungal agent can make the formed matrix layer 14 have an excellent anti-fungal effect.

[0045] The purifying bacteria agent can work synergistically with the soil condi...

Embodiment 1

[0052] The components of the hydraulic spraying substrate are as follows: 65 parts of wood fiber processed from straw and reed; 2.5 parts of water retention agent cross-linked by polyglutamic acid and methyl methacrylate; composed of polyvinyl alcohol, 2 parts of adhesive made from carboxymethyl starch processing; 6 parts of organic fertilizer made by mixing fermented chicken manure and peat soil; 0.8 parts of soil conditioner; 0.8 parts of compound microbial inoculants. The above components are mixed uniformly.

[0053] When spraying, add river water (that is, the ratio of the mass of the hydraulic spraying substrate to the mass of the river water) according to the material-liquid ratio of 1:10, and stir evenly to form a slurry substrate. The river water is taken from a small river near the company.

[0054] Such as Figure 1-4 As shown, before spraying construction, slope 11 is repaired, and nets are hung on the loose part of the slope. among them, figure 1 It is a partial sch...

Embodiment 2

[0062] In this example, the components of the hydraulic spraying substrate are as follows: 80 parts of wood fiber made from straw processing; 4 parts of water retention agent cross-linked by polyglutamic acid and sweet potato starch; made of sodium alginate 3 parts of the adhesive; 10 parts of organic fertilizer made of chicken manure and peat soil; 1 part of soil conditioner; 1 part of compound microbial inoculum. The above components are mixed uniformly.

[0063] When spraying, add river water (that is, the ratio of the mass of the hydraulic spraying substrate to the mass of the river water) according to the material-liquid ratio of 1:10, and stir evenly to form a slurry substrate. The river water is taken from a small river near the company.

[0064] The spraying construction method is the same as that of Example 1.

Abstract

The invention discloses a hydraulic spray seeding matrix for slope ecological restoration. The hydraulic spray seeding matrix comprises, by weight, 60-85 parts of wood fiber, 2-8 parts of a water-retaining agent, 1-5 parts of a binding agent, 5-15 parts of organic fertilizer, 0.4-4 parts of a soil conditioner and 0.5-5 parts of a complex microbial agent. The soil conditioner is formed by calciningof at least one of clinoptilolite, sepiolite, attapulgite and crushed corncobs, and the complex microbial agent includes an antifungal agent, a cleansing bacterial agent and an azotobacterin which are mixed together. The hydraulic spray matrix is directly sprayed on the slope to form a matrix layer after mixture of seeds and water and can effectively reduce the amount of soil and purify water quality.

Description

Technical field [0001] The invention relates to the technical field of slope ecological restoration, and more specifically, to a hydraulic spraying substrate for slope ecological restoration. Background technique [0002] Infrastructure construction such as railways, highways, dams, and mining of mines will cause a large number of rock and soil slopes. This increases the risk of landslides and serious soil erosion. The spraying technology uses a jetting machine to spray organic substrates such as grass seeds and water retention agents onto the slope. The organic materials are tightly combined with the slope under pressure to form a matrix layer for plant growth. This technology can be applied to slope ecological restoration. [0003] In the existing spraying technology, a large amount of soil, such as guest soil, needs to be mixed into the spraying substrate. However, the supply of soil is limited, and the use of soil can destroy vegetation in other areas. [0004] In addition, i...
