| description | The invention discloses a method for repairing and treating soil heavy metal pollution by using amino acid, and belongs to the field of soil treatment. The method for repairing and treating the heavy metal pollution of the soil by using the amino acid comprises the following steps: (1) adding cross-linked xylan nanofibers into the heavy metal polluted soil, and uniformly mixing to obtain pretreated soil; (2) mixing a compound amino acid ionic liquid with water, spraying the mixture into the pretreated soil, and standing to obtain treated soil; and (3) planting shepherd's purse on the surface of the treated soil, and removing the shepherd's purse when the shepherd's purse grows to a fruiting period to obtain the treated soil. By treating the soil polluted by the heavy metals through the method, the content of the heavy metals can be reduced, and the content of microorganisms in the soil can be increased.
