Embodiment 1

[0013] A material powder of weathered coal is selected and passed through a 1 cm sieve to obtain weathered coal powder for later use. Bacillus subtilis ( Bacillus subtilis ), Bacillus megaterium ( Bacillus megaterium ), Streptomyces jingyang ( Streptomyces jingyangensis ), Bacillus peptiformis ( Bacillus mucilaggtmosus ), Rhodopseudomonas palustris ( Rhodopseudanonas palustris ) were fermented and produced respectively, and the fermented bacterial liquid was respectively adsorbed with weathered coal powder material 10 times the weight, and the above 5 kinds of single bacterial agents after adsorption were mixed evenly in the ratio of 30:10:25:20:15 by weight. Microbial agent spare. The red-bed sandstone and red-bed mudstone rocks produced by slope excavation were crushed with a crusher and passed through a 2 cm sieve, and the local natural soil was crushed with tools and passed through a 2 cm sieve, and 10% of the sieved red bed was Sandstone rock powder, 30% red bed ...

Embodiment 2

[0015] The operating procedure was the same as in Example 1 during preparation. Only the type, quantity, specification, and water content of raw materials are changed within the scope specified by the operating procedure of the present invention, and the artificial soil for red bed sand-shale interbedded slope wounds containing microbial agents of the present invention is still prepared in the same way.

Abstract

The invention provides a preparation method of microbial agent-containing red-layer sandstone and mudstone interbedding side slope wound surface artificial soil. The microbial agent-containing red-layer sandstone and mudstone interbedding side slope wound surface artificial soil is prepared by effectively mixing the raw material ingredients of the microbial agent, red-layer sandstone or / and red-layer mudstone, farmland soil or / and natural soil, straw, livestock and poultry excrement, high-water-absorbility resin, cement, attapulgite powder and fertilizer under a certain condition. The preparation method has obvious effects of accelerating circulation of soil nutrient elements, increasing supply of soil available nutrients, improving soil physical and chemical characteristics and contributing to recovery of vegetation.

Description

[0001] technical field [0002] The invention relates to an artificial soil, in particular to a method for preparing an artificial soil for a red-bed sand-mudstone interbedded slope wound surface containing microbial agents. Background technique [0003] The red beds in my country are mainly distributed in the vast areas of Southwest, South China, Central China and Northwest China. In the construction of roads, hydropower development, mining and other projects in my country's red bed areas, many exposed red bed sands have been caused by slope excavation. Mudstone interbedded slope. The lithology of the red bed sand-mudstone interbed is that mudstone and sandstone are soft and hard. The mudstone has weak weathering resistance, while the sandstone has strong weathering resistance. The thin mudstone between sandstones is easy to form argillaceous interlayers. The sandstone in the red sand-mudstone interbed is the supporting framework in the slope body, and is generally hard i...
