Abstract

The invention discloses a carbon-based microbial organic fertilizer and a preparation method thereof. The organic fertilizer is prepared from the following components in parts by weight: 15-25 parts of biochar, 10-25 parts of ferric chloride, 1-5 parts of EM bacteria, 25-40 parts of cow dung, 25-35 parts of bran, 5-10 parts of citric acid, 10-15 parts of nano iron powder, 85-95 parts of distilledwater and 1-10 parts of honey. The preparation method is simple in preparation process and relatively low in cost; the fertilizer can be used for fertilization of land and crops such as fields, facility greenhouses, potted plants and heavy metal pollution, can effectively adjust the pH of facility soil, improve the soil structure and porosity, loosen the soil, promote accumulation and conversion of organic substances, reduce nitrate nitrogen and available phosphorus leaching loss of the soil, and increase the content of organic matters and N, P and K nutrients in the soil. The microbial activity can be improved, heavy metals in the soil can be effectively adsorbed, fixed and passivated, heavy metal pollution and continuous cropping obstacles of the soil can be repaired, and the yield and quality of crops can be improved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a carbon-based microbial organic fertilizer and a preparation method thereof. Background technique [0002] Biochar is an extremely carbon-rich, stable, and highly aromatized solid substance produced by pyrolyzing biomass at a low temperature (<700°C) under anoxic or hypoxic conditions. Biochar is mainly composed of aromatic hydrocarbons and elemental carbon or carbon with a graphite-like structure, and generally contains more than 60% of C elements, as well as H, O, N, S and other elements. Biochar has extremely low solubility, high melting and boiling point, highly carboxylic esterification, aromatization structure and aliphatic chain structure, carboxyl group, phenolic hydroxyl group, hydroxyl group, aliphatic double bond and aromatization and other typical structural characteristics, making biochar Charcoal has strong adsorption capacity and anti-oxidation capaci...
