Method for producing water-soluble humic acid fertilizer by rapidly degrading natural organics

Abstract

The invention relates to a method for producing a water-soluble humic acid fertilizer by rapidly degrading natural organics. The produced water-soluble humic acid fertilizer can increase the crop output, improve the quality of farm products and increase the soil fertility. The method comprises the following steps of: sorting and removing impurities from natural organics, crushing, degrading and activating in a reaction kettle, decompression exploding and concentrating to obtain finished products, wherein the temperature is 80 to 175 DEG C, the pressure is 3 to 12.5 barometric pressure, the optical wave is 364-468cm-1 ultraviolet light, a hydrolytic agent is 5 to 20 weight percent of KOH2, an oxidant is 3 to 12.5 weight percent of TiO and a guiding agent is 0.3 to 3 weight percent of FeSO4.

Description

1. Technical field: [0001] The invention relates to a fertilizer production method, in particular to a method for producing water-soluble humic acid fertilizer by artificially degrading natural organic matter rapidly. 2. Background technology: [0002] Soil humic acid comes from natural organic matter. There are a lot of natural organic matter in nature, such as livestock manure, human excrement, farmland waste, peat, lignite, weathered coal, etc. are humic acid raw materials. Soil humic acid is the product of the slow decomposition of natural organic matter by soil microorganisms. Due to the different biological stability of various organic substances, the difficulty of being decomposed by natural microorganisms varies greatly. According to the research of former Soviet scientists, cellulose can exist in soil for more than 500 years; lignin can last 1500-2000 years. The natural organic matter applied as organic fertilizer has fertilizer effect only when it is degraded int...

Problems solved by technology

However, the yield of biochemical humic acid is low and there are many restrictions. Because one kind of microorganism has specific functions, it is impossible to degrade multiple organic substances at the same time. For example, cellulolytic bacteria can only decompose cellulose, and they have the ability to decompose lignin and other organic substances. Second, microorganisms are living organisms that require suitable temperature, humidity and nutrition. Under natural conditions, it is difficult to meet the optimum living conditions for microorganisms, and the function of microorganisms is limited. Third, itching microorganisms directly convert organic matter into carbon dioxide and water. , a large loss of organic carbon
