Technical Field

[0001] The utility model relates to the technical field of soil, in particular to an in-situ repair device for soil that is lightly or moderately contaminated by cadmium. Background Art

[0002] Soil refers to a loose layer of material on the surface of the earth, which is composed of various granular minerals, organic matter, water, air, microorganisms, etc., and can grow plants. Soil is composed of minerals formed by weathering of rocks, organic matter produced by the decomposition of animal and plant and microbial residues, soil organisms, as well as water, air, oxidized humus, etc. Solid matter includes soil minerals, organic matter, and nutrients obtained by microorganisms after light inhibition and sterilization. Liquid matter mainly refers to soil moisture. Gas is the air present in the pores of the soil. These three types of substances in the soil constitute a contradictory unity. They are interconnected and mutually restricted, providing the necessary living conditions for crops and are the material basis of soil fertility.
