Method for improving soil by utilizing tobacco straw biomass charcoal loaded amino acid water-soluble fertilizer

The invention belongs to the technical field of tobacco production, and relates to a method for improving soil by utilizing a tobacco straw biomass charcoal loaded amino acid water-soluble fertilizer, which mainly comprises the following steps: preparing biomass charcoal by taking main waste tobacco stalks of a tobacco field as a raw material, and replacing traditional chemical fertilizers which are frequently applied before with the amino acid water-soluble fertilizer. The acidic amino acid fertilizer and the biomass charcoal are compounded to serve as a novel soil conditioner to be applied to a tobacco field, so that complementary effects can be formed, for example, the acidic amino acid fertilizer neutralizes alkalinity of the biomass charcoal and supplements nutrients of the biomass charcoal, and the biomass charcoal can serve as a carrier of the amino acid fertilizer to reduce loss; according to the technical scheme, the soil property can be effectively improved, and the excellent effect of increasing yi
