A kind of granulation method of microbial fertilizer

Abstract

The invention discloses a granulation method of microbial fertilizer, step S1: uniformly mix livestock and poultry manure and crushed straw according to a mass ratio of 1:1 to obtain an organic mixture, add water to the organic mixture and mix uniformly to obtain For the culture medium with a water content of 30% to 50%, after the culture material is obtained in S1, the culture medium is cooled, and the bacterial population is put into the medium, and after being fully mixed, it is placed in the reaction kettle at 20-30°C Fermentation and cultivation, through the use of livestock and poultry manure and straw as the culture of the biological flora, can provide a stable living environment for the flora, and can ensure the survival of the flora in the biological fertilizer. After fertilization, the soil can be To achieve a better effect, set up the extrusion structure, and the electrode ball can be in contact with the electrode plate to control the start and stop of the extrusion motor, not only to ensure the continuity of the extrusion, but also to stop the operation in time when the material is insufficient. To achieve the purpose of energy saving and environmental protection.

Description

technical field [0001] The invention relates to the field of biological fertilizer processing, in particular to a granulation method of microbial fertilizer. Background technique [0002] Ecological fertilizer mainly refers to microbial fertilizer, which is a product that causes crops to obtain specific fertilizer effects through the life activities of microorganisms. It is a kind of fertilizer used in agricultural production. It has a history of nearly 50 years in our country. Agent - bacterial fertilizer - microbial fertilizer, the evolution of the name has explained the gradual development of microbial fertilizers in my country, but for a long time, due to the unstable effect of some bacterial fertilizers, the number of bacteria is small, there are many invalid and harmful bacteria, bacteria The survival rate in the soil is low, resulting in the unsatisfactory effect of bacterial fertilizer on crop yield increase; [0003] When the existing biological bacterial fertilizer ...

[0002] Ecological fertilizer mainly refers to microbial fertilizer, which is a product that causes crops to obtain specific fertilizer effects through the life activities of microorganisms. It is a kind of fertilizer used in agricultural production. It has a history of nearly 50 years in our country. Agent - bacterial fertilizer - microbial fertilizer, the evolution of the name has explained the gradual development of microbial fertilizers in my country, but for a long time, due to the unstable effect of some bacterial fertilizers, the number of bacteria is small, there are many invalid and harmful bacteria, bacteria The survival rate in the soil is low, resulting in the unsatisfactory effect of bacterial fertilizer on crop yield increase;

[0003] When the existing biological bacterial fertilizer is in use, because the biological material powder is generally used as the culture medium of the biological bacteria during the production of the biological bacterial fertilizer, it is not conducive to the survival and reproduction of the bacterial flora. When it is used, the bacterial flora will die and affect Fertilization effect, when making biological bacterial fertilizer, it will be extruded through a granulator. During the production process, the continuity of production is not good, and there is no material, the granulator keeps working, consumes electric energy, and is not energy-saving and environmentally friendly. , when granulating, because the granulated fertilizer is wet and slippery, it is most likely to be contaminated with other strains, resulting in the corruption of nutrients in the fertilizer and affecting the fertility of the fertilizer
