Problems solved by technology

At present, the fertilizer produced by this method is mainly liquid organic fertilizer. The existing problems are that the content of insoluble matter is high, the nutrient content of nitrogen, phosphorus and potassium is low, and the content of humic acid is low, which has not reached the national liquid fertilizer "water-soluble fertilizer containing humic acid" (NY 1106-2010) product quality standard
The disadvantage of this method is that cake fertilizer, fish meal, and trace elements need to be mixed into the fermentation tank at the front end of fermentation, and it needs to be fermented for more than 1.5 months. , Livestock and poultry manure as the main raw material for anaerobic fermentation treatment of biogas projects produced biogas slurry

Abstract

The invention discloses a method for using biogas slurry to prepare a liquid manure containing humic acid. The preparing method of the liquid manure containing the humic acid comprises the steps of uniformly mixing potassium nitrate, potassium fulvic acid, ferrous sulfate, borax, diethyl aminoethyl hexanoate and naphthaleneacetic acid sodium salt in proportion to obtain a base fertilizer containing the humic acid and major elements, uniformly mixing the base fertilizer, the biogas slurry, a chelating agent and a stabilizer in proportion, continuously heating and stirring the mixture to obtain a black viscous liquid manure, cooling the liquid manure and uniformly mixing the liquid manure with diammonium hydrogen phosphate, ammonium nitrate phosphate, and amino acid to obtain the liquid manure containing the humic acid. The liquid manure containing humic acid developed from the method can not only achieve full amount of use of the biogas slurry, and can also promote an additional value of the biogas slurry; meanwhile, the prepared liquid manure product is good in quality, and is high in content of the humic acid, content of nitrogen phosphorous and content of potassium; in addition, the liquid manure containing humic acid developed from the method has the advantages that the processing technology is simple in procedures and efficient.

Description

technical field [0001] The invention relates to a method for preparing liquid fertilizer containing humic acid, in particular to a process method for preparing liquid fertilizer containing humic acid by using biogas slurry as raw material. Background technique [0002] Humic acid liquid fertilizer (including humic acid foliar fertilizer, flushing fertilizer, etc.) is a humic acid liquid fertilizer product containing humic acid and one or more nutrients required by crops. It has easy absorption, high utilization rate, and stress resistance. It is one of the important directions for the development of liquid fertilizers in my country in the future. [0003] In recent years, with the development of large-scale and medium-sized biogas projects, a large amount of biogas slurry has been produced. According to the statistics of "China Rural Energy Yearbook (2009-2013)", by the end of 2012, there were 15,026 large and medium-sized biogas projects in my country. According to the "Medi...
