Problems solved by technology

[0003] The technical problem to be solved: while protecting fruit trees, organophosphorus pesticides also leave a large amount of residues in the soil. There are few remedial methods for effectively removing systemic phosphorus in the soil, and none of them have good effects and effects. Therefore, new composite soil remediation agents are needed to remediate the problem of systemic phosphorus pollution in soil

Abstract

The invention belongs to the field of soil remediation and discloses a compound soil remediator and a preparation method thereof. The compound soil remediator comprises the following components in parts by weight: 13-24 parts of polyamide fibers, 5-13 parts of chitosan, 9-20 parts of sodium polyacrylate, 8-17 parts of polyethylene oxide, 5-14 parts of quicklime, 7-12 parts of magnesium fluosilicate and 4-10 parts of sodium bismuthate. The preparation method comprises the following steps: weighing the polyamide fibers, chitosan, sodium polyacrylate, polyethylene oxide, quicklime, magnesium fluosilicate and sodium bismuthate; and after uniformly mixing various components of the soil remediator, sealing to prepare the compound soil remediator.

Description

technical field [0001] The invention belongs to the field of soil restoration, and relates to a soil restoration agent and a preparation method thereof, in particular to a composite soil restoration agent and a preparation method thereof. Background technique [0002] Pesticide pollution to soil refers to the human input or discharge of pesticides that exceed their self-purification capacity into the soil environment, resulting in a reduction in the quality of the soil environment, affecting soil productivity and endangering environmental biosafety. The pollution of pesticides to soil is closely related to the physical and chemical properties of pesticides, the behavior of pesticides in the soil environment, and the natural environmental conditions of the pesticide application areas. Chemical pesticides include various insecticides, fungicides, herbicides and plant growth agents. Long-term and large-scale use of pesticides causes serious pollution and hazards. Pesticides po...
