Abstract
The present disclosure discloses a method for preparing a small-molecule organic water-soluble fertilizer. In the method, the biomass is crushed by collision into pulp, added with a trace element and a catalyst, and hydrolyzed and complete a chelation reaction, added with an inorganic fertilizer for nanometerization, subjected to vacuum evaporation and concentration and then added with a stabilizer, and ultrasonically homogenized to obtain the small-molecule organic water-soluble fertilizer. The pressurized differential speed gradient stirring effectively improves the degree of chelation between the trace element and the biomass; catalytic hydrolysis of the biomass with increasing the pressure improves the efficiency of hydrolyzing an organic macromolecule into small organic molecules; under the action of pressurized gradient grinding, the nanometerization degree of the inorganic fertilizer is improved; and the small-molecular organic water-soluble fertilizer homogenized ultrasonically has enhanced solubility, and is not easy to produce a precipitate after long-term storage.
