Method of producing solid organic carbon fertilizer

Abstract

The invention discloses a method of producing a solid organic carbon fertilizer and relates to a method of producing an organic fertilizer by using a fermenting technology. The method comprises the following steps: adding concentrated liquor of biological organic wastewater which accounts for 15% of the weight of a main ingredient which is prepared from biological crushed aggregates and has a moisture content of 45-55%; then adding zymophyte powder which accounts for 0.5% of the total weight of the materials and sufficiently mixing; directly piling up to form a material fermenting pile which is 1.0-1.2m high and not turning over the pile within 6-8 days; cooling the pile; spreading out the pile and spraying the concentrated liquor of biological organic wastewater which accounts for 18-25% of the weight of the main ingredient; adding the zymophyte powder according to the last dosage and uniformly mixing; piling up to from a material fermenting pile, not turning the pile within 6-8 days, and cooling the pile; then transferring the pile and building up a braising dry pile which is 2.5-3.0m high, not turning over the pile within 20-30 days and spreading out when the pile is slowly cooled and the moisture content of the fermented materials in the pile is reduced to 30%; and crushing and packaging the fermented materials. The zymophyte powder is biologic humic acid bacterial powder or straw composting powder.

Description

technical field [0001] The invention relates to a method for producing organic fertilizer by using fermentation technology. Background technique [0002] Carbon is the first of the macroelements necessary for plants and the energy source for metabolism. The classic plant nutrition and soil fertilizer science established on the basis of "chemical plant nutrition" founded by western scholars more than 170 years ago only recognize that the carbon needed by plants comes from CO 2 Gases are taken up by leaves and photosynthetically transformed by chlorophyll into a carbon "channel". This leads to the wrong positioning of organic fertilizers: organic fertilizers are not endowed with the function of providing organic nutrients to crops, so that organic fertilizers are made into "mineralized humus" that can only improve soil. These are concentrated in the current technical standards for commercial organic fertilizers in my country, and there is no index that expresses the organic ...

Problems solved by technology

Because traditional organic fertilizers only focus on the positioning of nitrogen, phosphorus, and potassium, the production process of this type of organic fertilizer does not consider the production and preservation of available carbon. Bio-organic materials undergo aerobic high-temperature fermentation and multiple turnings. Organic matter is decomposed into H 2 O and CO 2 The gas is discharged, and the drum is dried at high temperature, which not only discharges more CO 2 , the remaining small molecules of water-soluble organic carbon are also condensed into large molecules due to the high temperature above 80°C, and the produced organic fertilizers become a pile of empty shells lacking essence. It can be said that "the children are also thrown out when pouring dirty water !"
