High-temperature stage process of aerobic fermentation of agricultural waste
In order to optimize the process of the high temperature stage of aerobic fermentation,chicken manure and corn straw were used as raw materials.The single factor test and orthogonal test were carried out by selecting the temperature,time and dosage of the microbial agent in the high temperature stage as the process parameters.The pH,conductivity(EC),the ratio of carbon to nitrogen(C/N)and seed germination index were used as evaluation indexes to study the high temperature stage process of high temperature aerobic fer-mentation of agricultural waste.The results showed that the optimum technological conditions in the high temperature stage were as fol-lows:the addition amount of the microbial agent was 20 g/kg,the temperature was 75℃,and the fermentation time was 12 h.
