Problems solved by technology

These bacteria need to be inactivated at a high temperature of over 90 degrees Celsius for more than half an hour, but the fermentation temperature in the existing fermentation technology can reach up to 70 degrees Celsius, which is far below the temperature for inactivating these bacteria
In addition, the existing organic fertilizers have low organic matter and effective viable bacteria count, and the effect of applying organic fertilizers is not ideal.

Embodiment 1

[0028] A kind of production method of organic fertilizer, comprises the following steps:

[0029] Sterilization: pulverize flue-cured tobacco stalks to obtain pulverized raw materials. Since flue-cured tobacco stalks are long and rod-shaped, it is inconvenient to mix and adjust the fermentation parameters. Therefore, the collected raw materials need to be sent to a pulverizer to be crushed into a state of uniform size and texture, so that they can participate in subsequent production. The working condition of the pulverizer and the particle size and uniformity of the pulverized material are very important. The particle size of the pulverized raw material is controlled to 20mm. The pulverization effect has a great impact on the subsequent mixing of microbial agents and the mixing of materials in primary fermentation and secondary fermentation. have a direct impact. In the pulverization step, the dust and other substances produced by the pulverization of flue-cured tobacco stal...

Abstract

The invention discloses an organic fertilizer production method, which comprises: crushing flue-cured tobacco straw, and sterilizing for 30-45 min at a temperature of 90-100 DEG C to obtain a sterilized material; mixing a microbial agent into the sterilized material to obtain a mixed material, wherein the adding amount of the microbial agent is 0.07-0.13% of the mass of the sterilized material, and the microbial agent comprises Bacillus subtilis, Bacillus Licheniformis, saccharomycetes and Aspergillus Niger; and adding effective flora into the primary fermentation material, and carrying out secondary fermentation to obtain the organic fertilizer. According to the present invention, with the method, more than 95% of pathogenic bacteria can be reduced through early-stage high-temperature sterilization pretreatment, and primary fermentation and secondary fermentation propagation are carried out step by step so as to avoid the effective flora inactivation caused by the too high primary fermentation temperature, such that the effective flora can be sufficiently propagated, and the effective viable count can be increased.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a production method of organic fertilizers. Background technique [0002] In the past, flue-cured tobacco stalks were treated by incineration, which not only polluted the environment, but also caused a lot of waste of organic waste. Flue-cured tobacco stalks contain a large amount of nutrients, among which the potassium content can reach 8%, the total nutrient content can reach 10%, and the organic matter content is 80%, which is a good organic fertilizer raw material. There are also pathogens in flue-cured tobacco stalks, such as mosaic bacteria, bacterial wilt bacteria, black shank bacteria and so on. These germs need more than 90 degrees Celsius for more than half an hour to be inactivated, but the fermentation temperature in the existing fermentation technology can reach 70 degrees Celsius, which is far below the temperature for inactivating these germs. In addition, the ...
