Abstract

The invention discloses a soil remediation biochar improved material. The improved material comprises the following raw materials: biochar, humic acid, a microbial agent, amino acid, ammonia peat soil, diatomite, chitosan, activated carbon fiber, polyacrylamide, turfy soil, an organic fertilizer and sodium polyacrylate. The invention further discloses a preparation method of the improved material, the improvement effect on soil is improved by modifying the biochar, meanwhile, the organic fertilizer is added, so that the fertility of the improved material is improved, the use amount of the chemical fertilizer is reduced, the cost is saved, soil depletion, hardening and salinization cannot be caused, and the trend of energy conservation, environmental protection and sustainable development is met.

Description

technical field [0001] The invention relates to the technical field of soil improvers, in particular to a soil repair biochar improvement material and a preparation method thereof. Background technique [0002] Soil is a key resource for human survival, a renewable natural resource in the ecosystem, and an important part of the agricultural ecosystem. However, in recent years, due to various human production activities, heavy metals have entered the soil as pollutants, especially agricultural soils. Due to their stability, non-microbial degradation and mineralization, and long retention time, the degree of harm is similar to that of air pollution and water pollution. Pollution is comparable. The increasingly significant problem of soil heavy metal pollution will not only seriously threaten human health and life safety, but also cause other environmental pollution problems, such as water pollution and air pollution. Therefore, soil heavy metal pollution has attracted widesp...
