Novel preparation method of organic fertilizer

Abstract

The invention relates to the technical field of organic fertilizer production, and in particular relates to a novel preparation method of an organic fertilizer. The novel preparation method of the organic fertilizer is characterized by comprising the following production processes: a raw material adopting stage, a stage of fermentation in a reaction kettle, a sterilization stage, a strain amplification and propagation stage, an organic fertilizer raw material fermentation stage, a secondary fermentation stage, and an organic fertilizer obtaining stage. By adopting the novel preparation method disclosed by the invention, the production efficiency of the organic fertilizer can be greatly increased; moreover, harmful microorganisms, disease eggs and the like in an organic fertilizer raw material can be killed, and the quality of the organic fertilizer can not be influenced; the organic fertilizer disclosed by the invention is relatively simple in production process and relatively low in production cost.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer production, in particular to a novel preparation method of organic fertilizer. Background technique [0002] With the strict implementation of the national arable land policy, the application of organic fertilizers has received more and more attention from governments at all levels. Traditional organic fertilizer preparation method (see attached figure 2 ) are basically achieved by aerobic or anaerobic composting. With these traditional composting technologies, when the composting temperature reaches 60-70°C, it is necessary to turn over or use other methods to lower the temperature, otherwise the activity of biological bacteria will be seriously affected. , prolong the compost fermentation time. Moreover, the traditional composting technology needs to occupy a large amount of land area, and the composting process can easily cause the loss of nutrients, such as nitrogen, which is gene...

AI Technical Summary

Problems solved by technology

These germs will inevitably spread through some channels such as livestock and poultry manure, sick and dead livestock and poultry corpses, etc. If the composting process is not treated or treated insufficiently, it will cause great harm to people.

In addition, some raw materials used as compost also have composting risks, such as tobacco rods (the tobacco mosaic virus contained in it, the inactivation temperature should be above 90°C)

If the organic fertilizer made of these raw materials is used, there will be great risks
