Problems solved by technology

However, due to the lack of reasonable application of microbial agents in the currently known artificial soil preparation process, the restoration effect of the artificial soil on the wound surface of the red bed sand and mudstone interbedded slope is not ideal.

Embodiment 1

[0012] A material of weathered coal is selected and passed through a 1 cm sieve to prepare weathered coal for use. Bacillus subtilis ( Bacillus subtilis ), Bacillus megaterium ( Bacillus megaterium ), Streptomyces Jingyang ( Streptomyces jingyangensis ), Bacillus peptoneoid ( Bacillus mucilagtmosus ), Rhodopseudomonas palustris ( Rhodopseudanonas palustris ) Fermentation is carried out separately, the fermented bacterial liquid is adsorbed by 10 times the weight of weathered coal powder, and the above 5 kinds of adsorbed single bacterial agents are mixed uniformly in the ratio of 30:10:25:20:15 by weight. Microbial agents are reserved. The red-bed sandstone and red-bed mudstone rock produced by the excavation of the slope are crushed with a crusher and passed through a 2 cm sieve. The local natural soil is crushed with a tool and passed through a 2 cm sieve, and 10% of the red layer after sieving is selected Sandstone rock powder, 30% red mudstone rock powder, and 60% natu...

Embodiment 2

[0014] The operating procedure during preparation is the same as in Example 1. Only the types, quantities, specifications, and water content of the raw materials are changed within the scope specified by the operating procedures of the present invention, the artificial soil for the red-bed sand and mudstone interbedded slope wound surface containing the microbial agent is still prepared.

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

Technical field [0001] The present invention relates to artificial soil, in particular to a preparation method of artificial soil for red-bed sand and mudstone interbedded slopes containing microbial agents. Background technique [0002] 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 beds areas, a lot of exposed red beds are caused by slope excavation. Mudstone interbedded slope. The lithology of the red-bed sand-mudstone interbedded is that mudstone and sandstone are distributed between soft and hard. Mudstone has weak resistance to weathering, and sandstone has strong resistance to weathering. Thin mudstones between sandstones are easy to form argillaceous interbeds. The sandstone in the red sand-shale interbed is the supporting framework in the slope. It is generally hard in texture, high in uniaxial ...
