Soil remediation agent and using method thereof

Abstract

The invention belongs to the technical field of agriculture, and particularly relates to a soil remediation agent which comprises medical stone powder, humic acid humate, liquid gold calcium, a composite microbial agent, an amino acid composition, fulvic acid salt and acetic acid. The soil remediation agent disclosed by the invention can effectively coordinate the interaction among minerals, organic matters, moisture, air and microbial flora, so that the soil remediation agent is an organic whole meeting the soil health standard. The invention also relates to a use method of the soil remediation agent, and the use method comprises the following steps: deeply ploughing soil for a certain depth for the first time, and spreading the soil remediation agent on the surface of the soil for the first time at the dosage of 99-290kg / mu; and after the soil is placed for several days, deeply ploughing the soil for a certain depth for the second time, and spreading 190-530kg of the soil remediationagent on the surface of the soil for the second time.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a soil remediation agent and a method for using the soil remediation agent. Background technique [0002] With the development of agricultural intensification, due to the excessive and unreasonable use of chemical fertilizers and pesticides, the soil quality has deteriorated sharply, the balance and stability of the soil ecosystem have been severely damaged, and the substances and nutrients that cannot be transformed and absorbed by plants are increasingly accumulated in the soil. Soil acidification or salinization, soil aggregate structure is destroyed, soil compaction, poor air permeability, resulting in a decline in soil productivity. In addition, due to the reduction of organic matter in the soil, the diversity of the biological flora in the soil is destroyed to a certain extent, the metabolic function of the biological flora is lost, and the biological chain ...

Problems solved by technology

[0002] With the development of agricultural intensification, due to the excessive and unreasonable use of chemical fertilizers and pesticides, the soil quality has deteriorated sharply, the balance and stability of the soil ecosystem have been severely damaged, and the substances and nutrients that cannot be transformed and absorbed by plants are increasingly accumulated in the soil. Soil acidification or salinization, soil aggregate structure is destroyed, soil compaction, poor air permeability, resulting in a decline in soil productivity

In addition, due to the reduction of organic matter in the soil, the diversity of the biological flora in the soil is destroyed to a certain extent, the metabolic function of the biological flora is lost, and the biological chain of the beneficial and harmful flora is out of balance, thus preventing the growth of the biological bacteria on the plant nutrition. Transformation, limiting plant uptake of nutrients

Moreover, air pollution, water pollution, etc. have also led to the degradation of soil productivity.
