Xinhui orange pulp fermentation method, fermentation system and liquid fertilizer

The invention relates to the technical field of pulp fermentation, in particular to a Xinhui orange pulp fermentation method, a Xinhui orange pulp fermentation system and a liquid fertilizer. The method comprises the following steps: putting Xinhui citrus pulp, a microbial activator, an organic carbon source and an alkaline raw material into a fermentation container for fermentation to obtain a fermentation insoluble substance and fermentation liquor; the microbial activator is used for activating beneficial microbial populations of Xinhui citrus pulp aboriginal. According to the method, indigenous microorganisms of the Xinhui citrus pulp are activated by adopting the microbial activator, so that beneficial microbial populations can be quickly propagated, the fermentation process is accelerated, the decomposition is quick, and the fermentation and decomposition time is shortened to 1/3-1/2 (the normal Xinhui citrus pulp fermentation and field returning time is more than half a year, and the Xinhui citrus pulp
