Problems solved by technology

The production cycle is generally more than 1.5-2 months, the production time is long, and the area is large. More importantly, the organic fertilizer fermentation process is a process of mixed growth and metabolism of various microorganisms. The open production process is affected by equipment, Due to the limited conditions of the site, it is difficult to effectively control the fermentation process parameters such as temperature, humidity, ventilation, and agitation during the fermentation process. Therefore, it is also difficult to control the biomass of decomposed microorganisms and the dominant microbial species in different fermentation stages during the fermentation process. The release of key microbial target metabolites and the pretreatment of organic materials are well regulated, which greatly prolongs the time of the pre-fermentation stage of organic fertilizers and affects the quality of the final organic fertilizer. The need to improve the quality of agricultural products and improve the soil
Moreover, the design features and process of open facilities and equipment are also difficult to ensure the effective control of disease microorganisms, disease insect eggs and malodorous gas, which will cause serious pollution to the organic fertilizer production site and the surrounding environment.

Abstract

The invention relates to the field of organic fertilizer fermentation, and especially relates to an organic fertilizer complex bacteria leaven, a special device thereof, and an application of the organic fertilizer complex bacteria leaven in the quick-ripening pre-fermentation of an organic fertilizer. The complex bacteria leaven comprises mixed bacteria A and mixed bacteria B, the mixed bacteriaA comprise Pediococcus pentosaceus, Pichia farinosa and high temperature yeast, and the mixed bacteria B comprise Bacillus licheniformis, Bacillus pallidus and Bacillus laterosporus. The quick-ripening pre-fermentation device comprises a fermentation tank, a heat source comprehensive utilization unit, a deodorizing, cooling and purifying unit, a wastewater comprehensive utilization unit, a coolingsystem and a temperature control system. The humidity, temperature, dissolved oxygen and the like in the fermentation process are effectively regulated, and efficient decomposing microorganisms are combined, so the growth and the metabolism of organic fertilizer decomposing microorganisms are greatly improved, thereby physical crushing and biochemical degradation of organic materials are accelerated, and the harmless treatment process of the materials and the decomposing and mineralizing process of the organic materials are greatly shortened.

Description

technical field [0001] The invention relates to the field of organic fertilizer fermentation, in particular to an organic fertilizer compound bacteria starter and its special equipment and its application in the fermentation of organic fertilizer before fast ripening. Background technique [0002] my country's large-scale commercial production of organic fertilizers has a history of nearly 20 years. In the past 20 years, the production technology and equipment of organic fertilizers have made a qualitative leap compared with earlier ones. At present, the strip-stack process, the tank process and the closed fermentation tower process of organic fertilizer fermentation in my country have gradually matured and become the three mainstream processes for fertilizer production. The production cycle is generally more than 1.5-2 months, the production time is long, and the area is large. More importantly, the organic fertilizer fermentation process is a process of mixed growth and m...
