Preparation method of grape fruit residue three-stage-fermentation mirco-encapsulated multi-stage controlled-release organic fertilizer

Abstract

The invention discloses a preparation method of a grape fruit residue three-stage-fermentation mirco-encapsulated multi-stage controlled-release organic fertilizer. The method comprises the steps of stacking grape fruit residues, excrements of livestock, auxiliary materials and a leavening agent, starting a three-stage-fermentation process; reaching high temperature within a short time, completely killing harmful pathogenic bacteria, parasitic ovum and the like in leavening, relieving stink and quickly converting organic substances containing nitrogen and phosphor in the leavening into sterile leavening without plant diseases and insect pests; embedding and treating the sterile fruit residue leavening which is rich in organic substance and high in quick-acting nutrient content through pelletizing and mirco-encapsulating treatment technology to prepare the mirco-encapsulated multi-stage controlled-release organic fertilizer. The preparation method disclosed by the invention has characteristics of being simple and convenient to operate, low in cost, strong in harmless degree of the produced organic fertilizer and the like.

Description

technical field [0001] The invention relates to harmless treatment, in particular to a method for preparing grape pomace three-stage fermentation microencapsulated multi-stage controlled-release organic fertilizer. Background technique [0002] With the adjustment of the agricultural industrial structure and the change of the residents' dietary structure, the fruit and vegetable and their deep processing industries in various parts of my country have developed rapidly, resulting in a large amount of fruit and vegetable waste, which not only pollutes the environment, causes problems such as human health, but also affects Sustainable and healthy development of fruit and vegetable deep processing industry. At present, grape pomace is mostly discarded without treatment or after simple treatment. The common simple treatment techniques mainly include burying, drying, and chemical methods, but these methods cannot completely solve the problem of grape pomace. Some stubborn harmful ...

Problems solved by technology

At present, grape pomace is mostly discarded without treatment or after simple treatment. The common simple treatment techniques mainly include burying, drying, and chemical methods, but these methods cannot completely solve the problem of grape pomace. Some stubborn harmful bacteria produced during the piling of pomace can easily cause secondary pollution, pollute the environment more easily, and seriously affect human health and the development of related industries
