Soil improver for landscaping and preparation method thereof

Abstract

The invention discloses a preparation method of a soil improver for landscaping, comprising: mixing mulberry powder and phosphoric acid solution, adding disproportionated rosin and stirring evenly, extruding, activating at high temperature, washing, and drying to obtain pretreated mulberry powder Stir montmorillonite and polar solvent, add zinc dicarboxylate to continue stirring under stirring, filter, dry, pulverize, calcinate at 200-300°C for 1-2h, and pulverize to obtain pretreated montmorillonite; Add water to tree powder, add pretreatment montmorillonite under stirring state, ultrasonic treatment, add acrylamide, N,N'-methylenebisacrylamide, foaming agent, dispersing agent in turn under stirring state, stir until fully Soak, add initiator, stir evenly to obtain compound ingredients; send the compound ingredients into the forming mold, adjust the temperature to 70-80°C for 1-2h, irradiate treatment, then heat up and keep warm in the next stage, cool with the furnace, and crush to obtain landscaping Use soil amendments.

Description

technical field [0001] The invention relates to the technical field of landscaping, in particular to a soil improver for landscaping and a preparation method thereof. Background technique [0002] With the rapid development of the global economy, pollutants containing heavy metals enter the garden soil through irrigation, dry and wet deposition and other ways, resulting in the enrichment of heavy metals in the garden. Soil is one of the four major elements of the environment and has an indispensable role in the natural ecosystem. The role of substitution, with the development of industrialization, urbanization and high agricultural intensification, due to the pollution caused by heavy metal chemicals, more and more garden soil quality has declined, which has seriously affected the ecological environment. Heavy metal pollution It not only affects the quality of garden plants, but also involves the quality of the atmosphere and water environment, and can endanger the life and ...

AI Technical Summary

Problems solved by technology

[0003] Soil pollution not only changes the physical and chemical properties of the soil and deteriorates the soil, but also hinders or inhibits the flora composition and life activities of soil microorganisms, affects the transformation of soil nutrients and energy exchange, reduces or loses the ability of the soil, and causes soil pollution. The destruction of resources will deteriorate or interrupt the garden ecological environment circulation system

[0004] Existing traditional amendments mainly include minerals, phosphates, alkaline substances, sulfides, biochar, etc., which not only use a large amount, but also have weak interactions between soil amendments and heavy metal ions. During the soil remediation process, there may be rainfall and other situations, which will promote the migration of the modifier, and it is difficult to achieve the expected repair effect. Generally, it needs to be put in multiple times to ensure the repair effect. At the same time, it will cause secondary pollution, which needs to be solved urgently
