Method for preparing artificial soil for redbed sandstone/mudstone interbed side slope surfaces by utilizing biological algae

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...
