Humic acid microbial embedded fertilizer and preparation method thereof

Abstract

The invention discloses a humic acid microbial embedded fertilizer and a preparation method thereof. The fertilizer is prepared from the following raw materials: oyster shell powder, a hydrochloric acid solution (2 mol / L), chicken feather, rotten straw, urea, ammonium bicarbonate, a soil microbial inoculant, lotus pool mud, calcium bicarbonate, potassium chloride, a microbial embedding agent, and a proper amount of water. According to the preparation method, a modified embedding agent is used to embed microbes, the embedding agent reacts with the material that produce humic acid at first, the embedding agent is decomposed and adsorbed and can co-exist with the material, thus the vitality of microbes can be guaranteed, and the fertilizer has a higher biological value.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a humic acid microorganism-embedded fertilizer and a preparation method thereof. Background technique [0002] Microbial fertilizers can partially replace chemical fertilizers, reduce the loss and waste caused by their extensive use, and even cause soil salinization and environmental pollution. The common dosage forms of microbial fertilizers are either bacterial liquids received after fermentation, or made with peat as a carrier The two formulations are more convenient in preparation, but both have many disadvantages, such as after the bacterial agent is applied to the soil, the bacteria are directly exposed to the open state, which is easy to cause the death of the bacteria. Proliferate to a certain level within a certain period of time, which is not easy to achieve. The embedding method is one of the cell immobilization technologies developed in recent years. ...
