[0021] Example 1
[0022] A biochar fertilizer with high calcium content, made from the following raw materials by weight:
[0023] 70 parts of biomass raw materials, 30 parts of human and animal manure, 20 parts of additives.
[0024] Wherein, the biomass raw material is a mixture of corn stalks, cotton stalks, corn cobs, bean husks, husks, bagasse, tree residues, and wood chips, and the water content is controlled at 8%.
[0025] The human and animal feces are formed by drying, crushing and mixing the selected human and animal feces, and the water content is controlled at 18%.
[0026] The additive is a mixture of dried shrimp skin and kelp, which is crushed and dried.
[0027] The method for preparing the biochar fertilizer with high adsorption performance includes the following steps:
[0028] (1) Dry and crush the biomass raw materials into powder for use;
[0029] (2) Put human and animal feces into the above-mentioned biomass raw material and stir evenly to obtain mixture 1;
