Problems solved by technology

[0004] Most of the current compound fertilizers are compounded with inorganic fertilizers as raw materials, which can only provide inorganic elements to plants, but cannot guarantee the organic nutrition of plants
[0005] Animal manure is usually used as organic fertilizer, but the animal manure is applied directly to the land, resulting in low utilization of manure nutrients

Abstract

The invention discloses a preparation method and application of a fecal organic fertilizer and relates to the field of fertilizers. The preparation method includes: (1) collecting cattle, sheep and pig feces, mixing well, adding saturated lime water into the fecal mixture, soaking, and drying in the sun; (2) crushing the dried feces, adding lactic acid bacteria, saccharomycetes, nitrogen-fixing bacteria, zeolite powder and water, mixing well, fermenting under anaerobic conditions, filtering after fermenting, and collecting filtrate and residue; (3) mixing well the residue and ferric chloride,adding the mixture into a high-speed stirrer, stirring, sintering in a nitrogen atmosphere furnace, allowing natural cooling, adding hydrochloric acid into the mixture, allowing standing, centrifugingand filtering, collecting precipitate, and washing the precipitate with water; (4) mixing well the precipitate of step (3) and the filtrate of step (2), and ageing the mixture to obtain the fecal organic fertilizer. Utilization rate of the feces prepared herein via the preparation method can be greatly increased; a composite fertilizer made with the feces has high fertilizer efficiency and good slow-release effect.

Description

Technical field: [0001] The invention relates to the field of fertilizers, in particular to a preparation method and application of manure organic fertilizer. Background technique: [0002] Compound fertilizer refers to chemical fertilizer containing two or more nutrient elements. Compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It is very important for balanced fertilization, improving fertilizer utilization rate, and promoting high and stable yield of crops. role. [0003] Compound fertilizer production often uses soil testing formulas to measure soil nutrients. Soil testing formula fertilization is based on soil tests and fertilizer field experiments. According to the law of crop fertilizer requirements, soil fertilizer supply performance and fertilizer effects, organic fertilizers are used rationally. On the basis of this, the application amount, fertilization period and application method of nitrog...
