The invention provides a fermentation technology of low-salt fermented bean curd. The fermentation technology comprises the following steps: base preparing, inoculating and cultivating, spraying, pre-fermenting, hair-rubbing and pickling, and soup-filling. According to the technology, the bases are prepared by steam-boiling of soybean slurry; a mixed spore suspension of hair mould and Rhizopus oryzae is utilized in grafting; table salt is used for hair-rubbing and curing of the bean-curd white bases, wherein the weight of the table salt is 10-14% that of the bean-curd white bases; and alcohol with the alcoholicity being 16-20% is used for soup-filling. The fermented bean curd is prepared under multi-aspect coordinated actions, so that the prepared final products are small in individual difference and batch difference. The prepared low-salt fermented bean curd is good in appearance and taste and is not prone to deterioration.
