Abstract

The invention discloses a bioorganic-inorganic compound fertilizer containing nano-selenium and a preparation method of the bioorganic-inorganic compound fertilizer. The bioorganic-inorganic compound fertilizer containing nano-selenium comprises crop straws, selenium dioxide, animal waste, municipal sewage sludge, urea, monoammonium phosphate or diammonium phosphate, potassium chloride, a silicon-potassium fertilizer, cellulase, lactobacillus, candida utilis, bacillus subtilis, bacillus licheniformis, sodium borate, an alkaline agent, phosphoric acid, water and the like. The bioorganic-inorganic compound fertilizer is prepared by the following steps: preparing nano-selenium through reduction reaction; fermenting; burdening; crushing; pelleting; drying; sieving; packaging; and the like. According to the bioorganic-inorganic compound fertilizer, the problem that inorganic selenium is difficultly converted into nano-selenium and the problem of resource utilization of waste are simultaneously solved; the fertilizer is capable of increasing the soil fertility and preventing soil from hardening; the crop quality is improved; and the method disclosed by the invention is mild in reaction condition, simple in process, relatively low in production cost and easy for industrial production, and has good economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of harmless treatment of urban and rural wastes and resource reuse, and relates to a method for producing fertilizers from urban and rural wastes, in particular to a bio-organic-inorganic compound fertilizer containing nano-selenium and a preparation method thereof. Background technique [0002] The return of crop straw to the field and the reuse of waste resources have become issues of great concern in my country's agricultural and industrial development, which is of great significance for solving future energy crises and environmental problems. After years of research and development, the technology of turning straw, manure, and sludge into treasure has been greatly improved, and the technology of using these wastes to develop agricultural fertilizers has also been made public. [0003] In terms of using crop stalks to produce fertilizers, Chinese patents CN03122742.2 and CN 03122743.0 respectively disclos...
