Description

Technical Field

[0001] The present invention relates to the technical field of ecological restoration, and in particular to a method for rapid soil formation from fully weathered phyllite. Background Art

[0002] The rapid soil formation technology of fully weathered phyllite is a comprehensive engineering technology developed to address the problem of soil resource shortage in rocky mountain ecological restoration. Its technical background involves the particularity of geological conditions, the limitations of traditional soil formation methods, and the urgency of ecological restoration and engineering needs.

[0003] Traditional soil improvement or artificial soil technologies rely heavily on natural resources like loam, peat, and humus, but these technologies have the following limitations. First, they rely on imported soil (high-quality soil shipped from abroad) or industrial amendments, potentially damaging the ecosystem elsewhere. Furthermore, they rely on non-renewable resources (such as peat). Second, they are economically and materially expensive (transporting imported soil, fertilizer, and water-retaining agents), require complex laying processes, and require continuous fertilization and irrigation for maintenance. Some existing artificial soils may contain heavy metals from industrial waste, potentially introducing the risk of external contamination.

[0004] Therefore, it is necessary to provide a new method for rapid soil formation of fully weathered phyllite to solve the above technical problems. Summary of the Invention

[0005] The technical problem solved by the present invention is to provide a method for rapid soil formation of fully weathered phyllite, which uses local materials, can reduce environmental damage, and can reduce restoration costs by more than 50%.

[0006] To solve the above technical problems, the present invention provides a method for rapid soil formation from fully weathered phyllite, comprising the following steps: S1: raw material preparation: crushing and sieving the fully weathered phyllite to a particle size of <1 cm, collecting and crushing the surface leaf litter to a diameter of <2 mm; S2: Activation of the microbial agent: dilute the rapid soil-forming microbial agent with water and mix it with the crushed fallen leaves at a mass ratio of 5:1; S3: Raw material ratio: 100 parts of sieved fully weathered phyllite and 2.4 parts of fallen leaf mixture containing bacterial agent are taken according to mass percentage to prepare a mixture; S4: Mixing and fermentation: Spread the mixture flatly with a thickness of ≥5m, maintain a moisture content of 50-60%, and stack for 60 days.

[0007] Preferably, the rapid soil-forming bacterial agent is a Bacillus subtilis preparation, with an effective viable bacterial count of ≥5×10 8 CFU / g.

[0008] Preferably, in S2, the dilution ratio of the rapid soil-forming bacteria agent is 1:100 (mass ratio).

[0009] Preferably, the surface leaf litter layer is selected from forest litter naturally accumulated in phyllite producing areas.

[0010] Preferably, in S4, temperature monitoring is performed every 24 hours to control the temperature of the pile body to be between 20°C and 45°C.

[0011] Preferably, the physical and chemical indicators of the final product are: bulk density 1.10-1.35 g / cm³, pH 7.2-7.8, conductivity 150-180 μS / cm, and clay content ≥5.5%.

[0012] Compared with related technologies, the rapid soil formation method of fully weathered phyllite provided by the present invention has the following beneficial effects: The present invention provides a method for rapid soil formation from fully weathered phyllite, which uses local materials completely. This method can avoid the predatory exploitation of foreign soil resources by traditional imported soil methods, conforms to the circular economy, and converts weathered phyllite into usable resources. It can save transportation and raw material costs, is particularly suitable for remote mining areas / mountainous areas, has better long-term economic efficiency, relies on the self-sustaining nature of local microbial communities, and reduces subsequent maintenance investment. It mimics the structure of natural soil, forms stable aggregates through the synergistic action of minerals, organic matter, and microorganisms, and has sustainable fertility, utilizing the weathering of the phyllite's own minerals to continuously release elements such as potassium and magnesium. It has no secondary pollution, avoids the environmental risks of industrial waste (such as fly ash) improvement methods, and conforms to green remediation standards.
