Abstract
The invention provides a method for preparing a biological fertilizer by brown coal humic acid. With phanerochaete chrysosporium CICC40719 as a starting strain; 100-300ml solution containing 0.3% of KH2PO4, 0.15%g of MgSO4 7H2O, 0.01% of vitamin B1, 5% of pulverized brown coal and 94.54% of deionized water is inoculated with the phanerochaete chrysosporium, which is cultured by a shaking table at the temperature of 28 DEG C for 96 hours to prepare a bacterial culture suspension I; another 100-300ml solution containing 0.3% of KH2PO4, 0.15%g of MgSO4 7H2O, 0.01% of vitamin B1, 10% of pulverized brown coal and 89.54% of deionized water is inoculated with 5% of the bacterial culture suspensionI to prepare a bacterial culture suspension II; another 100-300ml solution containing 0.3% of KH2PO4, 0.15%g of MgSO4 7H2O, 0.01% of vitamin B1, 15% of pulverized brown coal and 84.54% of deionized water is inoculated with 5% of the bacterial culture suspension II which is cultured by the shaking table to prepare a bacterial culture suspension III which is separated and purified to obtain a phanerochaete chrysosporium acclimatized strain. A culture medium is inoculated with the culture medium and cultured for 24 hours, and fermentation broth is prepared. The brown coal is pulverized by a pulverizer and sieved by a 30-mesh sieve to obtain pulverized coal, which is added with water for regulating the moisture content of the pulverized coal to 35-40%, 12-15% of ammonia water (wet basis), and 2% of rice hull (wet basis), the wet pulverized coal is stirred evenly, spread out indoors to a thickness of 8cm, and thermostatically cultured at the temperature of 28 DEG C for 30 hours, then sulfuric acid solution with 8% percentage concentration is used for neutralizing the degraded pulverized brown coal, the pH value of which is adjusted between 6.5 and 7.5, after being dried with hot air at the temperature of 55 DEG C and pulverized, the biological fertilizer is prepared.
Description
(1) technical field
The present invention relates to a kind of is raw material prepares humic acid bio-fertilizer behind microbial fermentation method with brown coal.
(2) background technology
Brown coal are low because of its calorific value, and industrial using value is less, is referred to as low grade coal.At present, the output of China's brown coal and reserves are all bigger, and therefore, the development and use of brown coal just become the new problem of current coal-mining industry research.In recent years, exploring the new way of development and use low grade coal both at home and abroad.Because be rich in humic acid in the brown coal molecular composition, and the effect of the too busy to get away soil microorganisms of the formation of humic acid in the coal, therefore, coal can be decomposed by Institute of Micro-biology too.In order to study the degradation problem of microorganism to brown coal, researcher was once isolated many microbial strainss from soil and brown coal both at home and abroad, and the humic acid in humic acid and the weathered coal is changed.Usually the material that contains a large amount of lignin structures in the brown coal with the microorganism of the lignin degrading brown coal of degrading, just might therefrom obtain the chemical that some have special value.These chemical are high water solubles, contain oxygen and nitrogen-containing functional group on its aromatic structure more, have the effect of regulating soil property, promoting plant-growth and stabilize water coal slurry, and can be used for as immunoadjuvant and sewage-treating agent etc.
It is starting strain that this project adopts the Phanerochaete chrysosporium in the white-rot fungi, and through enrichment culture, domestication obtains superior strain, has opened up one for the microbiological deterioration and the utilization research of brown coal and has realized that the energy is benign, the new road of Sustainable development.This has important contribution and far reaching significance to the sound development of safeguarding the whole world under the urgent day by day global form of current energy dilemma and environmental protection problem.Though the liquefaction of the microorganism of brown coal utilizes research still to be in the initial stage at present, there are many problem expectations to solve, but compare with traditional industrial method for transformation, have that energy consumption is low, conversion condition is gentle, transformation efficiency is high, a series of superiority such as the economic benefit of converted product, using value height, equipment requirements are simple, and be subject to people's attention day by day and pay close attention to, its research is just in the ascendant.
(3) summary of the invention
The object of the invention is to provide a kind of preparation method of brown coal humic acid bio-fertilizer.
