Abstract

The invention discloses a method for preparing a functional composite water-soluble fertilizer and belongs to the technical field of water-soluble fertilizers. The method comprises the following steps: 1, preparing a sodium alginate solution, adding an aqueous solution of calcium chloride to carry out a calcification reaction, adding a hydrochloric acid solution to carry out a decalcification reaction after the reaction is ended, adding water to wash after the reaction and then dehydrating; 2, adding potassium humate, citric acid and water into the previous water-containing alginic acid, and uniformly mixing to obtain a first mixed solution; 3, weighing bacillus subtilis, bacillus mucilaginosus and polyacrylamide to mix, adding a first mixed solution, adding pseudo-amino polysaccharide and glucose, and stirring to prepare a second mixed solution; and 4, adding a surfactant and polyvinylpyrrolidone into water to stir, adding a second mixed solution, stirring and mixing uniformly, cooling to room temperature, and split charging. The water-soluble fertilizer prepared by the method disclosed by the invention has the advantages of providing nutrition for plant growth and development, improving the immunity of the organism, improving the crop quality, resisting bacteria, preventing diseases, controlling soil agglomeration and the like.

Description

technical field [0001] The invention belongs to the technical field of water-soluble fertilizers, and in particular relates to a preparation method of functional composite water-soluble fertilizers. Background technique [0002] Water-soluble fertilizers are liquid or solid fertilizers that are dissolved or diluted in water and used for irrigation and fertilization, foliar fertilization, soilless cultivation, soaking seeds and dipping roots, etc. The production process of solid water-soluble fertilizer mainly includes the processes of batching, feeding, mixing, discharging, and packaging. The production process of liquid water-soluble fertilizer mainly includes the processes of batching, dissolving, chelating, compounding, filtering, and packaging. All processes can be carried out at low temperature. It is carried out under normal pressure or normal temperature and pressure, which requires very low energy consumption, and because there is no generation and discharge of "thre...
