Abstract

The production method is suitable for the technical field of organic fertilizers, and provides a production method for producing an organic fertilizer by using cow dung. The production method is simple in steps, and cow dung, waste vegetable leaves and waste animal internal organs are used as main raw materials of the organic fertilizer and are humified under the action of a fermentation bacteriaagent; the cow dung is high is high in organic matter content and low in mineral element content, so that the physical property of viscous soil can be improved, and water permeability and air permeability of the viscous soil can be improved; the waste vegetable leaves contain rich potassium, phosphorus and other microelements, so that on one hand, nutrition is provided for the fermentation bacteria agent, and on the other hand, nutritional ingredients in the organic fertilizer are increased; and the animal internal organs contain a large amount of microorganisms and have a high content of nitrogen and phosphorus, so that humification is further facilitated, and the recycling rate of wastes in the ecological environment is also greatly improved.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, and in particular relates to a method for producing organic fertilizers from cow dung. Background technique [0002] Cattle farms produce tens of thousands of tons of cow dung every year. Cow dung seriously pollutes the environment. If it accumulates for a long time, it will not only produce unpleasant odors, but also because it contains harmful substances such as coliform bacteria and nematodes and pests, it cannot be removed in time. Treatment will easily breed bacteria and pests, causing environmental pollution and affecting human health. Cow dung is a metabolite of cattle. Dried cow dung contains 10%-20% crude protein, 1%-3% crude fat, 20%-30% nitrogen-free extract, 15%-30% crude fiber, rich in nutrients ; Therefore, cow dung can be used in feed processing, organic fertilizer production, biogas fermentation, etc. Compared with chicken manure and pig manure, cow dung has lower or...
