Problems solved by technology

However, due to the lack of rational application of bio-algae agents in the currently known artificial soil preparation process, the repair effect of artificial soil on the wound surface of red bed sand and mudstone interbedded slopes is not ideal.

Embodiment 1

[0013] A material powder of zeolite is selected and passed through a 1 cm sieve to prepare zeolite powder for use. Brevis lunata ( Eunotia lunaris ), Chlamydomonas ( Chlamydomonas sajao Lewin ), Nitrogen-fixing Anabaena ( Anabaena azotica ), Chromococcus cubic ( Chroococcus gardner ), Chlorella ( Chlorella vulgaris ) were fermented and produced separately, and the fermented algae liquid was adsorbed with zeolite powder 5 times the weight respectively, and the above five adsorbed single algae agents were mixed evenly in the ratio of 20:20:20:30:10 by weight to obtain biological Algae preparations. The red bed mudstone rock produced by slope excavation was crushed with a crusher and passed through a 2 cm sieve, and the local farmland soil was crushed with tools and passed through a 2 cm sieve. After sieving, 35% of the red bed mudstone rock powder, 55 % farmland soil powder and 10% peat were uniformly mixed to prepare a rock-containing mixture for later use. The weight...

Embodiment 2

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

Abstract

The invention provides a method for preparing artificial soil for redbed sandstone / mudstone interbed side slope surfaces by utilizing biological algae. The method is characterized by preparing the artificial soil by effectively compounding the raw materials such as the biological algae, redbed sandstone rocks or / and redbed mudstone rocks, farmland soil or / and natural soil, turfs, straws, livestock and poultry manures, super water absorbent resin, cement, attapulgite powder and fertilizers under certain conditions. The method has remarkable effects of accelerating the circulation of nutrient elements in soil, increasing the supply of available nutrients of soil, improving the physical and chemical properties of soil and promoting vegetation restoration.

Description

[0001] technical field [0002] The invention relates to artificial soil, in particular to a method for preparing artificial soil for red-bed sand-mudstone interbedded slope wounds by using a biological algae agent. 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 in texture...
