Problems solved by technology

Artificial soil is an important material basis in ecological slope protection engineering, but currently known artificial soil needs to add a large amount of mature soil taken from local cultivated land, which not only causes the destruction of limited soil resources, but also greatly increases the construction cost

Embodiment 1

[0011] The red layer mudstone rock produced by slope excavation was crushed with a crusher and passed through a 2cm sieve to obtain crushed rock for future use. The natural air-dried silkworm dung with a water content of 15% is uniformly mixed with industrial rubber tannin extract, industrial humic acid, industrial bentonite, and agricultural plant ash in a weight ratio of 25:5:50:15:5. Containing the silkworm manure mixture for later use. Get component weight percentage and be respectively 50% crushed rock, 0.5% silkworm manure-containing mixture, 35% peat, 2% rice straw cut into ≤3cm, 3% chicken manure with a water content of 15%, 2% % Cow manure with a moisture content of 15%, 7% pig manure with a moisture content of 15%, 0.05% polyacrylamide, 0.05% carboxymethyl cellulose, 0.1% urea, 0.2% superphosphate , 0.1% potassium chloride is compounded to obtain the final product.

Embodiment 2

[0013] 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 procedures of the present invention, and the artificial soil for red bed mudstone slope wounds of the present invention is still prepared in the same way.

Abstract

The invention provides a redbed shale slope raw surface artificial soil preparation method, which prepares the artificial soil with raw material components including redbed shale rock, compound containing silkworm excrement and / or wormcast and / or algae residue, peat, straw, livestock and poultry manure, polyvinyl alcohol or polyacrylamide, carboxymethyl cellulose, nitrogen fertilizer, phosphate fertilizer and potassium fertilizer which are effectively mixed under certain conditions. The preparation method has significant effects in speeding up the formation of redbed shale slope raw surface artificial soil aggregate structure, increasing the water and fertilizer-keeping performances of the soil, improving the physical and chemical properties of the soil and promoting the plant growth and development.

Description

technical field [0001] The invention relates to artificial soil, in particular to a preparation method of artificial soil for red layer mudstone slope wound. Background technique [0002] The topography of my country's red-bed areas is relatively undulating, and construction of roads, hydropower, and mines often requires the excavation of a large number of slopes, resulting in many exposed red-bed mudstone slopes, resulting in serious soil erosion and ecological damage. Red bed mudstone is a special clay rock with complex mineral composition, mainly composed of clay minerals, followed by detrital minerals, epigenetic minerals, ferromanganese and organic matter. Red bed mudstone particles are easily broken, low in strength, easy to disintegrate and soften when exposed to water, have rapid weathering characteristics and weak expansion characteristics, and are rich in nutrients such as potassium, phosphorus, calcium, magnesium, iron, and manganese. The use of ecological slope ...
