Method for producing organic fertilizer by using high-temperature anaerobic sludge, pig manure and chicken manure as raw materials

Abstract

The invention discloses a method for producing organic fertilizer by using high-temperature anaerobic sludge, pig manure and chicken manure as raw materials. The method is characterized by comprising the following steps: first mixing the raw materials comprising high-temperature anaerobic sludge, pig manure and chicken manure by a mass ratio of 1.5-2.5:0.5-1.5:0.5-1.5; inoculating fermentation deodorization strains 1-3% of the total weight of the raw materials; fermenting at room temperature for 3-7 d; and inoculating fermentation composting strains 2-4% of the total weight of the raw materials; controlling a fermentation temperature at 20-30 DEG C, and relative humidity at 30-40%; flipping the materials every two hours; and fermenting for 3-7 d, wherein a mass fraction of organic matters in the fertilizer, calculated by dry substances, achieves higher than 45%, and a mass fraction of the total nutrients, calculated by dry substances, reaches higher than 5%, and a mass fraction of water, calculated by fresh sample meter, is less than 30%; and finally packing and storing. The invention has advantages that the produced organic fertilizer is rich in beneficial substances, can provide comprehensive nutrition of crops, has long fertilizer efficiency, and is the main nutrients for green food production.

Description

technical field [0001] The invention relates to an organic fertilizer production method using high-temperature anaerobic sludge, pig manure and chicken manure as raw materials, and belongs to the technical field of organic fertilizer processing. Background technique [0002] At present, due to the inadequacies of chemical fertilizers in the process of use, more and more people are aware of them, and the advantages of corresponding organic fertilizers are becoming more and more obvious. The comparison is as follows: [0003] (l) Organic fertilizers contain a large amount of organic matter and have obvious effects of improving soil and fertilizing; chemical fertilizers can only provide inorganic nutrients for crops, and long-term application will cause adverse effects on the soil, making the soil "more and more greedy". [0004] (2) Organic fertilizers contain a variety of nutrients, and the nutrients contained are fully balanced; while chemical fertilizers contain a single ty...

Problems solved by technology

[0004] (2) Organic fertilizers contain a variety of nutrients, and the nutrients contained are fully balanced; while chemical fertilizers contain a single type of nutrients, long-term application is likely to cause nutrient imbalance in the soil and food

[0006] (4) The fertilizer effect time of organic fertilizer is long; the fertilizer effect time of chemical fertilizer is short and fierce, which is easy to cause nutrient loss and pollute the environment

[0008] (6) During the production and processing of organic fertilizers, as long as they are fully decomposed, the drought resistance, disease resistance, and insect resistance of crops can be improved after application, and the use of pesticides can be reduced; long-term application of chemical fertilizers will reduce plant immunity. It often requires a large amount of chemical pesticides to maintain crop growth, which may easily cause the increase of harmful substances in food

[0009] (7) Organic fertilizers contain a large number of beneficial microorganisms, which can promote the biological transformation process in the soil, which is conducive to the continuous improvement of soil fertility; long-term large-scale application of chemical fertilizers can inhibit the activities of soil microorganisms, resulting in a decline in the automatic adjustment ability of the soil
