Preparation method of bedding rock spray seeding matrix

Abstract

The invention relates to a preparation method of a spray seeding matrix for bedding rocks, which comprises the following steps: mixing garden wastes and breeding wastes, carrying out harmless treatment to prepare garden waste compost with a nest interlaced structure, and mixing the garden waste compost with spoil, a nitrogen fertilizer, a phosphate fertilizer, a potash fertilizer, trace elements and an adhesive in proportion to form the spray seeding matrix. The nest interlaced structure can increase the adhesiveness of the substrate, stabilize the substrate, is light in weight, and can reduce the erosion of the substrate caused by gravity, and meanwhile, the garden waste compost has the advantage of lasting fertilizer efficiency as an organic fertilizer, can promote the structure aggregation of the substrate, and has lasting fertilizer efficiency. By adding nitrogen, phosphorus, potassium fertilizers and trace elements, the effective nutrient content of the matrix can be guaranteed, nutrient supply of the plants in the early stage is guaranteed, and disease resistance and stress resistance of the plants are improved. Garden waste, breeding waste and spoil are used as raw materials, an export for resource recycling is provided, and waste is turned into wealth.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a preparation method for bedding rock spraying matrix, and is especially suitable for vegetation restoration of bedding rock slopes and concrete slope protection. Background technique [0002] Foreign soil spraying technology is currently one of the main engineering technologies for rapid slope reforestation at home and abroad. It originated in Britain and the United States and was actively promoted in Japan. Our foreign soil spraying technology was introduced from Japan and has been used in urban road slope greening. widely used. The spraying substrate is an important factor to ensure the success of the guest soil spraying technology. It is uniformly mixed soil, organic matter, fertilizer and other additive materials according to a certain ratio, and is evenly sprayed to the area to be protected according to the designed thickness through high-pressure equipment a...

Problems solved by technology

[0003] However, when the spraying matrix is ​​applied on bedding rock slopes, due to its poor rain resistance and wind erosion performance, gravity erosion is prone to occur in the later stage, causing the spraying matrix to slip and fall off, and the lack of nutrients leads to a decrease in vegetation coverage.
