Problems solved by technology

In order to meet the needs of the special habitat of engineering construction slopes, artificial soils are often added with a large amount of chemical products such as adhesives and stabilizers, which have some adverse effects on the soil microbial ecosystem and physical and chemical properties, resulting in artificial soil cultivation of slopes. The effect of fertilizer and vegetation restoration is not ideal

Embodiment 1

[0014] A material powder of peat is selected and passed through a 1 cm sieve to make peat powder for subsequent use. Chlorella ( Chlorella vulgaris ), Chromococcus cubic ( Chroococcus gardner ), Chlamydomonas ( Chlamydomonas sajao Lewin ), Bacillus megaterium ( Bacillus megaterium ), Streptomyces jingyang ( Streptomyces jingyangensis ), Bacillus peptiformis ( Bacillus mucilaggtmosus ) were fermented and produced separately, and the fermented microbial liquid was adsorbed with 5 times the weight of peat carbon powder, and the above 6 kinds of single microbial preparations after adsorption were mixed evenly in the ratio of 20:25:15:20:10:10 by weight Prepare multi-microbial preparations for later use. Take the multi-component microbial preparation of 92% by weight, 3% of pig manure with a water content of 10%, 2% of humic acid, 2% of citric acid, and 1% of chitosan to make the final product through compounding. product.

Embodiment 2

[0016] The operating procedure was the same as in Example 1 during preparation. Just change the type, quantity, specification and water content of the raw materials within the scope specified by the operating procedure of the present invention, and still make a special bio-improvement agent for slope artificial soil of the present invention in the same way.

Abstract

The invention provides a biologic modifier special for side slope artificial soil, which is prepared by effectively compounding and mixing a fermentation preparation of various microorganisms such as algae, fungi and the like with livestock and poultry dung, humic acid, critic acid and chitosan under a certain condition. The biologic modifier has obvious effects on promoting the microecological repair of soil, increasing the supply of available nutrient for the soil, improving the physical and chemical properties of the soil, fertilizing soil productivity and promoting revegetation.

Description

technical field [0001] The invention relates to a soil improver, in particular to a special biological improver for slope artificial soil. [0002] Background technique [0003] my country is a large mountainous country, and mountainous areas account for 69% of the total land area of ​​our country. There will be a large number of exposed slopes in the construction of roads, hydropower development, and mining in mountainous areas, resulting in a large number of secondary bare land and serious water and soil erosion, causing great damage to the ecological environment. Artificial soil is an important material basis in the ecological slope protection project of exposed slope wounds. Using artificial soil to implement artificial soil and plant ecological protection measures on exposed slope wounds can stabilize the slope, maintain water and soil, and beautify the environment. Good effect (such as Chinese patent ZL200810046488.6). In order to meet the needs of the special habit...
