Problems solved by technology

The salt content in saline soil is high. When urea is applied to the soil, the urease activity of urea increases due to the salt, which increases the volatilization loss of nitrogen fertilizer and ammonia in saline soil, resulting in the loss of urea, and the phosphate ion in saline soil is prone to antagonism , hinder the absorption and utilization of phosphorus by crops, resulting in the lack of phosphorus in the process of plant growth

Abstract

The invention provides a soil remediation agent applied to salinized land and a preparation method thereof. The soil remediation agent comprises high-molecule organic acids, high-molecule organic acid potassium or high-molecule organic acid calcium, active functional bacteria, water-retaining agents, soil penetrating agents and other additives. According to the soil remediation agent, the solubility of calcium sulfate and calcium carbonate in the soil can be improved and cured calcium ions can be activated through combination of complexation of high-molecule polymers, sedimentation and separation of the soil penetrating agents on saline and alkaline ions in the soil and activation of microorganisms on the soil; the activated calcium ions are used for replacing sodium ions absorbed by soil colloid through ion exchange action; the replaced sodium ions are combined with negative functional groups to form water-soluble complex; the water-soluble complex enters below plowing layer along with irrigation water; the harm to the growth of crops is avoided.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a soil restoration agent for saline land; the invention also relates to a preparation method of the soil restoration agent for saline land. Background technique [0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil, reducing its concentration to an acceptable level, or converting toxic and harmful pollutants into harmless substances. Soil remediation fertilizers can increase soil nutrients, especially the loss of nitrogen in the soil; and can reduce the number of fertilization operations, save labor and costs, and avoid damage to seeds or seedlings caused by excessive fertilization. The salt content in saline soil is high. When urea is applied to the soil, the urease activity of urea increases due to the salt, which increases the volatilization loss of nitrogen fertilizer and ammonia in saline soil...
