Heavy metal soil remediation agent

Abstract

A heavy metal soil remediation agent is prepared by the following raw materials, by weight, 8-12 parts of water-retaining agents, 6-14 parts of sulfocompound, 4-8 parts of calcium oxide, 3-7 parts of microorganism chelating agents, 8-24 parts of mushroom residues, 7-11 parts of wood bits, 6-12 parts of chitosan, 6-10 parts of magnesium fluosilicate, 7-14 parts of polyethylene oxide, 3-5 parts of iron sulfate, 7-9 parts of apatite, 4-27 parts of ardealite powder, 2-4.5 parts of fulvic acid potassium, 0.1-0.2 part of coco coir and 0.4-0.7 part of grass carbon. The heavy metal soil remediation agent has the advantages that various heavy metal pollutants in polluted soil can be lowered effectively, the soil air permeability can be increased, and the growing environment of crops can be improved.

Description

technical field [0001] The invention relates to a heavy metal soil restoration agent. Background technique [0002] According to the survey, there are about 50 million mu of moderately and severely polluted cultivated land in mainland China.
