Description

Method for producing plant total element liquid fertilizer by utilizing livestock and poultry manure sewage and returning process Technical Field The invention belongs to the technical field of liquid fertilizers, and particularly relates to a method for producing a plant total element liquid fertilizer by utilizing livestock and poultry manure sewage and a returning process. Background With the large-scale development of livestock and poultry breeding industry, the discharge amount of livestock and poultry manure sewage is increased year by year, and a large amount of organic matters, nitrogen and phosphorus nutrient salts and pathogenic microorganisms contained in the livestock and poultry manure sewage can cause environmental problems such as soil pollution, water eutrophication and the like if directly discharged, and the traditional manure treatment mode (such as composting and direct returning) has the defects of low efficiency, serious nutrient loss, high secondary pollution risk and the like. Meanwhile, the demand for efficient and environment-friendly liquid fertilizer in agricultural production is increasingly urgent.
