Soil contamination-removal and anti-toxicity fertilizer-retaining yield stabilizing agent and preparation method thereof

Abstract

A soil contamination-removal and anti-toxicity fertilizer-retaining yield stabilizing agent and a preparation method thereof relate to the technical field of soil improvement. The soil contamination-removal and anti-toxicity fertilizer-retaining yield stabilizing agent is prepared by mixing raw materials: zeolite, attapulgite, medical stone, vermiculite or sepiolite, calcined lime, pulverized fuel ash, bean cakes or rape seed cakes, carboxyl starch sodium or acrylamide, manganese sulfate, zinc sulfate and borax, and then is applied into soil along with fertilizer in seeding. The soil contamination-removal and anti-toxicity fertilizer-retaining yield stabilizing agent is simple to prepare and convenient to use, the raw materials are purely natural and are abundant and easily available in storage, the soil structure can be improved, the soil pollution can be eliminated, the fertilizer effect can be stabilized, and the plant output can be promoted to be improved. The ecological pollution can be reduced so as to return a healthy life environment for people. The physical property of soil can be changed, the hydrogen potential can be mediated, the fertilizer retaining power can be improved, the usage amount of the fertilizer can be decreased, the pesticide residues of chlorine, arsenic, phenol, mercury and the like can be eliminated, the utilization rate of plant to the fertilizer can be improved, and the environment-friendly and ecological benefits can be achieved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a production-stabilizing agent for decontamination, detoxification and fertilizer conservation of soil and a preparation method thereof. Background technique [0002] Soil is the basis for the survival of plants and the basis for the survival of human beings. However, in recent decades, in order to obtain high yields from the earth, a large amount of chemical fertilizers and pesticides have been used, which has damaged the soil structure, lost its activity, agglomerated, mineralized, and cracked. Cause soil acidification, secondary salinization, and damage to the sustainability of land cultivation. Because farmers do not understand the changes in soil nutrients, long-term use of habitual fertilization and excessive fertilization lead to phosphorus enrichment, nitrogen fertilizer denitrification and loss, and the utilization rate is only about 30%. Source pollution, poll...

AI Technical Summary

Problems solved by technology

[0003] Most of the current existing technologies on soil mediation use chemical raw materials, and a small part of them are biological materials. Although a small amount of mineral materials are used, the amount is small, which cannot achieve the purpose of fully ecologically adjusted soil structure.

Moreover, chemical materials and biological materials are expensive, and the supply of resources is scarce, which cannot meet the extensive use of land mediation
