Abstract

The invention belongs to the technical field of soil amendments, and discloses a charcoal-based microbial soil amendment and a preparation method thereof. The charcoal-based microbial soil amendment comprises, by mass, 15-20 parts of charcoal, 3-5 parts of humic acid, 2-4 parts of a microbial agent, and 5-8 parts of an organic fertilizer. The microbial agent is prepared from the following components in parts by mass: 3 to 4 parts of photosynthetic bacteria, 2 to 4 parts of bacillus pumilus, 2 to 3 parts of bacillus cereus and 1 to 2 parts of bacillus subtilis. According to the invention, the firewood and the corn straw are used for preparing the biomass charcoal, so the obtained biomass charcoal can effectively improve soil and regulate nutrients in the soil, and improvement effect on the soil is improved by modifying the biomass charcoal; and the organic fertilizer is added into the soil conditioner, so soil fertility can be improved while soil improvement is realized, and soil improvement effect is enhanced.

Description

technical field

[0001] The invention belongs to the technical field of soil improvers, in particular to a biochar-based microbial soil improver and a preparation method thereof. Background technique

[0002] At present: Biochar is a highly aromatized insoluble solid substance produced by pyrolysis of biomass under complete or partial anoxic conditions. Biochar can improve the soil very well. Most of the biochar is alkaline, and applying it to the soil can increase the pH value of the acidic soil. Biochar has a complex porous structure and a large specific surface area. Applying it to the soil can increase soil permeability, improve soil aggregates, absorb more water and nutrient ions, and increase soil water capacity and nutrient uptake capacity. Biochar contains a certain amount of easily decomposed organic compounds. Soil microorganisms can use it as a carbon source, which can increase the biomass and activity of soil microorganisms. Biochar has a complex pore structure a...
