Loose Fuzhuan tea based on natural eurotium cristatum growing and preparation method thereof

The invention provides a loose Fuzhuan tea based on natural eurotium cristatum growing and a preparation method thereof. The method comprises the following steps: firstly, performing glaze boiling on raw dark green tea and water, then performing filtration to obtain filtrate, uniformly mixing the filtrate and the raw dark green tea to obtain glaze mixed materials, and sequentially performing pile fermentation, steaming, compression molding and eurotium cristatum growing on the glaze mixed materials to obtain tea bricks; then opening the tea bricks, when eurotium cristatum in the tea brick is thick, crushing the tea brick outside a eurotium cristatum growing chamber into a state before compression molding, then uniformly spraying a zein solution with the mass concentration of 2-10% to fix the eurotium cristatum, then growing the eurotium cristatum in an environment of 40-70% at 26-30 DEG C, and finally drying to obtain the loose Fuzhuan tea, the falling of the eurotium cristatum can be obviously reduced, and t
