Clear liquid type distiller's grain fermentation liquid fertilizer and preparation method thereof

Abstract

The invention relates to a clear liquid type distiller's grain fermentation liquid fertilizer and a preparation method thereof. The clear liquid type distiller's grain fermentation liquid fertilizer is prepared from, by weight, 55-65 parts of distiller's grain fermentation liquid two-stage solid-liquid separation treating liquid, 3-4 parts of a fulvic acid mineral source, 15-25 parts of urea, 7-15 parts of diammonium phosphate and 7-15 parts of potassium sulphate. The preparation method of the clear liquid type distiller's grain fermentation liquid fertilizer comprises the following steps of distiller's grain pretreating, anaerobic fermenting, solid-liquid separating, product compounding, product packaging and the like. The clear liquid type distiller's grain fermentation liquid fertilizer and the preparation method thereof have the advantages that the efficient liquid fertilizer product with the high added economic value is produced, the crop yield can be increased, the fruit quality can be improved, the soil fertility can be improved, and crop disease and pest damage can be prevented and reduced.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a clear liquid type distiller's grain fermented liquid fertilizer and a preparation method thereof. Background technique [0002] In the liquor brewing process, the residue after distilling alcohol or alcoholic beverages from grains is called distiller's grains. Distiller's grains are high in organic matter, rich in protein, cellulose, starch, etc., rich in nitrogen, phosphorus, potassium, calcium and various trace elements, and are also perishable, degenerate, smelly, and breed mosquitoes and flies. my country's distiller's grain waste resource treatment is still in its infancy. At present, a large number of distiller's grains are processed directly as livestock feed and as organic fertilizer. Because these two processing methods are limited by locality, processing scale, economy and organic matter Affected by factors such as utilization efficiency, it is not feasible to p...
