Sterile, environmental-protection and efficient pure manure organic fertilizer preparation method

Abstract

The present invention relates to a sterile, environmental-protection and efficient pure manure organic fertilizer preparation method, which comprises: (1) uniformly mixing chicken manure being subjected to air-drying and active humic acid in a material hopper, and conveying to a crusher through a belt conveyor to crush so as to form a crushed material; (2) spraying a decomposer to the crushed material through a spraying device, and pouring the treated crushed material into a screening machine to screen so as to obtain the undersize; and (3) conveying the undersize into a stacking region through the belt conveyor to carry out a complete composting process for 72 h, carrying out stacking turning every 24 h, and carrying out a deodorization treatment to obtain the sterile, environmental-protection and efficient pure manure organic fertilizer. The preparation method of the present invention has characteristics of simpleness, short production time, high production efficiency, low production cost, small occupation area, no pollution, zero emission, and no requirement of consumption of other outside energy sources.

Description

technical field [0001] The invention belongs to the field of organic fertilizers, in particular to a method for preparing aseptic, environment-friendly and high-efficiency pure manure organic fertilizers. Background technique [0002] At present, due to the diversity of raw materials, the corresponding production and processing techniques of commercial organic fertilizers are also diverse. In the prior art, the fermentation method of beneficial microbiota organic fertilizers is one of the commonly used methods. The method is mainly composed of photosynthetic bacteria, A live bacterial preparation composed of more than 80 kinds of microorganisms with different functions including lactic acid bacteria, yeast, fermenting filamentous bacteria and actinomycetes. These microorganisms constitute a complex and stable micro-ecological system, which can inhibit the activities of harmful microorganisms, especially pathogenic bacteria and spoilage bacteria. Adding beneficial microorgan...

AI Technical Summary

Problems solved by technology

In short, it is to add beneficial microorganisms to organic materials for fermentation to form organic fertilizers. Although this method can produce organic fertilizers, there are the following problems: straw needs to be added and crushed

The configuration of the bacterial agent also needs brown sugar, which increases the production cost of the organic fertilizer

And the fermentation time is long, and it needs to occupy a large area to accumulate manure and straw, the biological bacteria are not easy to preserve, the shelf life of the produced organic fertilizer is short, and the production efficiency is low
