Abstract

The invention discloses a method for preparing a phosphorus-containing organic compound fertilizer. The method comprises working procedures of pretreating grain stillage, preparing the phosphorus-containing organic compound fertilizer and granulating and packaging and specifically comprises the following steps of: (1) pretreating the grain stillage, namely uniformly mixing the grain stillage and water, inoculating an aspergillus fumigatus seed nutrient solution, and fermenting by raw materials; (2) preparing the phosphorus-containing organic compound fertilizer, namely inoculating more than one of an aspergillus niger seed nutrient solution, a bacillus megaterium seed nutrient solution, a lactobacillus seed nutrient solution and a white rot fungi seed nutrient solution into 25 to 65 parts of pretreated grain stillage, 35 to 60 parts of phosphate tailing powder and 5 to 20 parts of water, uniformly mixing, and fermenting by the raw materials; and (3) granulating the fermented organic compound fertilizer and packaging. According to the method, main wastes of a wine industry and main wastes of a phosphorite industry are used comprehensively and recycled; and a prepared product can be used for agricultural production, so that the yield of crops is increased, and the fertilizing soil is improved.

Description

Technical field [0001] The present invention is a biological organic compound fertilizer field, which involves a preparation method of phosphorus -containing organic compound fertilizer. Background technique [0002] Solid liquor is the main by -product of liquor production, and it is also the main pollutant of liquor production.According to statistics, the amount of lost production is 4 to 8 times the yield of liquor. At present, it needs to be dealt with by more than 50 million tons in the country.Therefore, the comprehensive utilization of distillery is of great significance for resource development and environmental protection.On the one hand, due to sorghum, glutinous rice and other raw materials, the loss of protein, amino acids, vitamins, and various trace elements of losing are losing the comprehensive use of solid liquor.On the other hand, due to the special production process, the acidity is high, and it is easy to corrupt and deteriorate. If it is not treated in time, ...
