Trough aerobic fermentation process is the aerobic fermentation process of organic fertilizer. The principle of high-temperature aerobic rapid composting technology is actually a process in which microorganisms decompose organic materials. In this process, organic materials become small molecules of yellow humic acid under the decomposition of microorganisms, and the unusable nutrients are decomposed into available nitrogen, phosphorus and potassium, It is a process of organic matter transformation to transform macromolecular proteins into small molecular amino acids and realize the degradation of organic materials. At the same time, the composting temperature is above 60 ℃, which can kill a large number of pathogens, and the composting process can also be achieved for a period of time. The low-temperature aging process of organic fertilizer can make microorganisms reproduce gently and continue to decompose organic materials. In addition, in the process of reproduction and decomposition of organic materials, it can secrete a large number of biological stimulants and improve the quality and efficiency of organic fertilizer. However, in the active period of microorganisms, a large amount of oxygen is required. The height of trough compost is high and it is difficult for oxygen to enter, so external force is required to carry out forced aeration in the reactor.
