[0026] Beneficial effects:

[0027] This invention's soil remediation structure, through the sequential arrangement of a compacted nutrient layer, a humus sludge layer, a water-fixing layer, and a cover layer on top of the original soil layer, facilitates construction of each soil layer. It also positions the humus sludge layer and supplies it with nutrients for growth. The cover layer provides wind and weathering protection for the soil surface, safeguarding the underlying soil layers and ensuring effective soil bioremediation and water fixation. The water-fixing plate, via recessed modules, guides infiltrating water, allowing it to quickly seep into the humus sludge layer through flow holes, supplying moisture to microorganisms and plant roots. After rainfall, when the soil remediation structure contains a large amount of water, some overflows from the recessed modules, while the remaining water at the same height is stored in the raised modules, reducing contact between water and the upper air layer, further minimizing evaporation and achieving water fixation. The flow holes enhance water infiltration and reduce water overflow. Attached Figure Description
