Soil spray sowing substrate for ecological protection of side slopes and substrate mixture

Abstract

The invention relates to a soil spray sowing substrate for ecological protection of side slopes and a substrate mixture. The substrate is prepared by a method comprising the following steps: 1) dispersing and pulverizing oyster mushroom bran, mixing 78%-80% of oyster mushroom bran, 8%-10% of wheat straw and 10%-12% of pig manure in mass percent to obtain a solid mixture, and adjusting C / N and moisture content; 2) preparing a mixed culture of bacillus subtilis, lactobacillus, aspergillus niger and beer yeast; 3) inoculating the mixed culture into the solid mixture according to the inoculation amount, performing composting fermentation for 20-22 days until the mixed culture is thoroughly decomposed, and performing air-drying to obtain a thoroughly decomposed substance; and 4) proportionallymixing the thoroughly decomposed substance with the wheat straw to obtain the substrate. The obtained substrate is high in fertilizer efficiency and capable of obviously improving all physicochemicalproperties of planting soil; the substrate mixture is capable of promoting seedling emergence, growth and development of plants and realizing the effects of quickly covering slopes and recovering greening; and the obtained substrate can completely replace organic substances such as turfy soil, changes wastes into valuables, is low in cost, saves resources and is suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of guest soil spraying, and in particular relates to a guest soil spraying base material for slope ecological protection, and also relates to a guest soil spraying base material mixture using the base material. Background technique [0002] With the large-scale development of infrastructure in our country, slopes with a certain slope have been built on both sides of roads, railways, rivers, mines, etc., which are called side slopes to maintain the stability of roadbeds, embankments, and mountains. Due to its special place and environment, after the construction is completed, it is difficult to restore the vegetation of the slope, especially some cut and excavated slopes, which are generally steep, often with exposed bedrock, easy to lose water and soil, and easy to collapse slope attachments. Not only affects the ecological environment, not beautiful, but also has potential safety hazards. [0003] Soil spr...

Problems solved by technology

Peat soil can improve soil, supply nutrients, and promote plant growth, but it is a non-renewable resource, and the buried amount on the surface of the ground is small and thin. Excessive excavation will inevitably bring new damage to the environment. Causes new ecological costs; the rising price of peat soil also increases the cost of the base material mixture, increases the investment in slope ecological protection projects, and limits the use and promotion; in order to control the cost of base material, the construction party often adopts the method of reducing peat soil The way of dosage, resulting in the substandard quality of base material mixture, seriously affected the effect of slope ecological protection
