Biochar-based organic special fertilizer for tomatoes and production method thereof

Abstract

The invention provides a production method of a biochar-based organic special fertilizer for tomatoes, which is prepared from the following components in parts by weight: 20-25 parts of biochar, 45-50parts of organic matter, 6-9 parts of nitrogen (N2), 3-5 parts of phosphorus (P2O5), 6-9 parts of potassium (K2O), 1-3 parts of potassium sulfate, 3-5 parts of ammonium molybdate, 0.5-1 part of humicacid, 1.5-2.5 parts of wood vinegar, 1-2 parts of wood tar, 0.05-1 part of beneficial microbial inoculum, 0.5-1 part of fertilizer controlled release agent and 1 part of forming aid. The organic matters are solid livestock and poultry manure with the water content of less than or equal to 30% and decomposed organic plants. The preparation method comprises the following steps: carrying out high-temperature pyrolysis on crop straws to prepare charcoal, carrying out mixed fermentation on the charcoal and organic matters for 10-20 days, adding the components, mixing and granulating the mixture byusing a granulator, and finally spraying wood tar onto the granular fertilizer. The special fertilizer contains a large amount of nutrient elements such as nitrogen, phosphorus and potassium and trace elements such as zinc and iron, so that waste resources are effectively utilized, soil is improved, the number of soil microorganisms is increased, and tomatoes are high in quality and yield.
