Abstract

The invention discloses a soil conditioner. The soil conditioner is prepared from, by weight, 10-20 parts of activated sludge, 15-30 parts of core cobs, 8-17 parts of desulfurized gypsum, 10-50 parts of salsola collina, 9-17 parts of siliceous petrochemical powder, 5-13 parts of amino acid powder, 6-12 parts of rice bran, 10-20 parts of humic acid, 9-15 parts of zeolite powder, 5-11 parts of modified diatomite, 7-14 parts of water-soluble high polymer, 3-5 parts of mycelia, 2-4 parts of protein residue, 1-3 parts of cluster mallow fruits, 2-3 parts of herba lycopi and 1-2 parts of szechwan Chinaberry fruits. The soil conditioner uses activated sludge, corncob, salsola collina and the like as raw materials, the raw materials have a synergistic effect, the physical and chemical properties of soil can be improved, greenhouse gas emissions are reduced, and the soil conditioner has the functions of sterilization, bacterium inhibition and plant growth regulation.

Description

technical field [0001] The invention belongs to the technical field of soil improver, and in particular relates to a soil improver and a preparation method thereof. Background technique [0002] The release of carbon dioxide by farmland soil organic carbonization is an important way of greenhouse gas emissions. As the implementation of greenhouse gas emission tasks becomes easier, how to reduce greenhouse gas emissions in land and increase carbon sinks in terrestrial ecosystems has become a hot topic in current research. [0003] Biochar is a fine-grained, porous carbonaceous material obtained by pyrolyzing biomass under oxygen-free or oxygen-limited conditions. The main components of biochar are carbon, hydrogen, oxygen, and ash elements such as potassium, calcium, sodium, magnesium and silicon. The elemental composition of biochar is related to the carbonization temperature and the soil type and plant species of the fabric's growth place. Biochar has a developed pore str...
