Treatment method for landscaping soil remediation

Abstract

The invention relates to a treatment method for landscaping soil remediation, which is used for remediation of alkaline soil and comprises the following steps: sampling and detecting original soil, determining the ratio of a soil additive, pretreating the soil, adding the soil additive into the pretreated soil and uniformly mixing; the soil additive comprises an organic matrix and a mineral material; the soil pretreatment comprises soil crushing and soil sieving treatment. By means of the treatment method for landscaping soil remediation, the pH value of alkaline soil can be effectively reduced, the landscaping requirement is met, meanwhile, the problem of soil hardening can be solved through soil pretreatment and organic matrix adding, and the situation that the EC value of soil exceeds the standard can be avoided; the soil is crushed and sieved, so that uniform mixing of the soil additive and the soil is facilitated, and the use of the soil additive is reduced; by smashing and sieving the soil, the oxygen content in the soil can be increased, and growth of plants for landscaping is facilitated.

Description

technical field [0001] The invention relates to the field of landscaping soil restoration, in particular to a processing method for landscaping soil restoration. Background technique [0002] Due to the poor soil quality of landscaping soils, the roots of green seedlings are affected, resulting in poor germination and even degradation. Before soil improvement, the soil was hardened and the content of impurities was high, and it was difficult to achieve and complete the restoration without thorough crushing and screening. [0003] For alkaline soil, the existing technology generally adopts the addition of acidic substances to the alkaline soil, and adjusts the pH value of the alkaline soil through the acidic substance, so that the pH value of the soil is reduced to near neutral to meet the needs of greening; and The existing technology needs to add a large amount of organic fertilizers and other structural substrates when adding soil amendments, which affects and damages the...

AI Technical Summary

Problems solved by technology

[0002] Poor soil quality generally exists in landscaping soil, which affects the rooting of green seedlings, resulting in poor germination and even degeneration and decline

Before soil improvement, the compaction is serious and the impurity content is high. It is difficult to achieve and complete the restoration without thorough crushing and screening.

[0003] For alkaline soil, the existing technology is generally to add acidic substances in alkaline soil, and adjust the pH value of alkaline soil by acidic substances, so that the soil pH value is reduced to close to neutral to meet the needs of greening; and The existing technology needs to add a large amount of organic fertilizer and other structural substrates when adding soil improvers, which affects and damages the aggregate structure of the soil, and the organic fertilizer that has not been thoroughly fermented and carbonized will cause soil damage during the process of increasing the amount. The EC value (soil conductivity) exceeds the standard, exceeding the upper limit of the EC value for plant growth, which is not conducive to plant growth
