The present application relates to the technical field of soil, and discloses a water-permeable and moisture-retaining soil, a preparation method and application thereof, the water-permeable and moisture-retaining soil is prepared by mixing yellow soil, sand, rotten straw, modified biochar and modified polylactic acid according to specific weight parts, and can be used for ecological restoration of mines, wherein the modified biochar is obtained by carboxylation modification of pomelo peel biochar, has a multi-level pore structure and a hydrophilic carboxyl functional group; the modified polylactic acid is prepared by modification of a silane coupling agent by grafting a functionalized meglumine to polylactic acid, and hydroxyl groups and siloxane structures are introduced; the soil of the present application builds a continuous and stable water transport pore network through the synergistic effect of the components, has excellent water permeability and water absorption and moisture retention capacity, can effectively improve soil structure, prevent hardening, and improve water and fertilizer utilization rate; the soil of the present application is environmentally friendly and biodegradable, and is suitable for various scenes such as agricultural planting, landscaping and ecological restoration of mines.

This invention provides a method for the rapid weathering of coal gangue into soil through a microbial-plant synergistic enhancement. Applied to the fields of ecological restoration of coal gangue mountains and artificial intelligence, the method constructs a positive feedback loop of root exudates and microbial metabolites to achieve dual acid erosion weathering by microorganisms and plants, significantly increasing the chemical weathering rate of coal gangue. Combined with the precise control of the ANNA algorithm, it achieves rapid soilification of coal gangue. The ANNA algorithm avoids getting trapped in local optima from the source through reverse learning and dual population initialization. The adaptive bias operator and continuous penalty function coefficients achieve a smooth balance between global exploration and local exploitation capabilities, improving convergence speed and computational accuracy. The algorithm is adaptable to restoration scenarios with different coal gangue types and different climatic conditions, exhibiting excellent robustness.

This invention relates to a bacterial strain that improves the physical structure of red mud and its application. The strain BRT1 is classified as Staphylococcus epidermidis. Staphylococcus epidermidis The accession number is GDMCC No. 66375, the accession date is May 22, 2025, and the depositary institution is Guangdong Microbial Culture Collection Center. This invention utilizes the BRT1 strain, which efficiently improves the physical structure of red mud, solving the technical problem of poor red mud structure. The BRT1 strain secretes extracellular polymeric substances (EPS) as a bio-cementitious agent, effectively promoting the aggregation of red mud particles and forming stable aggregate structures.
