The invention discloses a fast fermentation method of green leaf mustard. The fast fermentation method comprises three procedures including pretreatment, salting and sealing of a pool, wherein the salting procedure also comprises four substeps of salting lower green leaf mustard, adding auxiliary materials and aged salt water, crudely extracting myrosase and adding lactic acid bacteria. The fast fermentation method disclosed by the invention has the advantages that due to addition of glucose, the concentration of substrates can be increased, the growth factors of the lactic acid bacteria can be increased and the growth of the lactic acid bacteria can be accelerated; the green leaf mustard contains myrosinase for inhibiting the growth of the lactic acid bacteria, and due to addition of the myrosase, the myrosinase can be damaged and the fast fermentation of the green leaf mustard can be promoted; since the naturally-fermented lactic acid bacteria is insufficient, the acidity of the salted green leaf mustard can be increased. The fast fermentation method disclosed by the invention has the characteristics that the fermentation of the lactic acid bacteria can be accelerated, the acidity of the leaf mustard can be increased and the salting and fermentation time for the leaf mustard can be shortened.
