The invention discloses a total nutrition carbon-based soil remediation fertilizer and a production method thereof and belongs to a carbon-based soil remediation fertilizer used for improving a soil environment and enhancing the maturity, yield and quality of flue-cured tobacco. The needs of nutritive materials in the crop growth process can be met, and conservation of soil quality is realized. The fertilizer mainly comprises the following components: 30-40% of biomass charcoal, 20-40% of a sesame seed cake fertilizer, 2-10% of a multi-element mineral fertilizer, 10-25% of humic acid and 15-25% of a composite fertilizer. In the fertilizer production process, key technologies such as biomass pyrolysis, cake fertilizer fermentation and the like are adopted, so that the effects of improving the C/N ratio in the soil, improving the quality and improving the aroma quality and aroma quantity of the flue-cured tobacco. The carbon-based soil remediation fertilizer disclosed by the invention is an optimal fertilizer for producing organic green agricultural products, can be widely applied to agricultural crops such as tobacco, fruit trees, corn, rice, sweet potatoes, watermelons, vegetables and the like and has important practical significance on agricultural sustainable development.
