Problems solved by technology

[0003] Due to the limitation of soil conditions, directly adding organic matter to soil improvement under such site conditions often requires a large amount, and the organic matter decomposes quickly, is susceptible to water and soil erosion, and cannot be well preserved in the soil. Improve soil organic matter in a short time Content effect is poor

Abstract

The invention relates to a soil remediation material and in particular to a timbered soil ecological remediation material and a preparation method thereof. The timbered soil ecological remediation material is prepared by the following raw material components in parts by weight: 220-260 parts of forestry and agricultural residues, 55-68 parts of sludge, 76-85 parts of animal livestock manure, 15-25 parts of a binder, and 0.5-1.5 parts of a microbial agent. The invention further provides the preparation method for the above timbered soil ecological remediation material. The timbered soil ecological remediation material is capable of maintaining soil fertility, enabling nitrogen phosphors potassium nutrients to be released from raw materials to soil, promoting soil microbial activity and promoting decomposition thereof, improving soil porosity, reducing soil bulk density, increasing soil gas permeability, and solving conditions that the soil fertility is lost and physical and chemical properties are poor and the like.

Description

technical field [0001] The invention relates to a soil restoration material, in particular to a woodland soil ecological restoration material and a preparation method thereof. Background technique [0002] Compared with the soil used in traditional planting, forest planting soil has less organic matter, poor fertility, poor physical and chemical properties, easy compaction, poor water storage, fertilizer storage, ventilation, water permeability, etc., and buffers against temperature changes and droughts and floods This is the main problem that forest land soil is not conducive to the growth and development of forest trees; due to the stress of soil environment conditions, direct afforestation often results in low survival rate and poor growth, and it is easy to cause the phenomenon of no forest after afforestation every year. Therefore, for this type of soil Afforestation after a certain degree of restoration can reduce the cost of vegetation restoration and improve the effe...
