The invention discloses a method for inducing rapid formation of Chinese saprophytic
boletus primordium, and belongs to the technical field of
edible fungus cultivation. The method comprises the following steps: activating a
boletus sinensis strain JSJ-Bx1, inoculating the
boletus sinensis strain JSJ-Bx1 into a culture medium, and carrying out dark culture; the preservation number of the boletus sinensis strain JSJ-Bx1 is CGMCC (China General
Microbiological Culture Collection Center) No.42007, and the boletus sinensis strain JSJ-Bx1 is preserved in the China General
Microbiological Culture Collection Center; performing liquid
fermentation culture on the hyphae which are activated and are almost overgrown on the flat plate to obtain
fermentation liquid; inoculating a cultivation material with the
fermentation liquid, performing dark culture until the
bottle / bag is full of hyphae, covering the
bottle / bag full of the hyphae with soil, covering the surface with non-
woven fabric as a protective layer, and performing
hypha culture and light culture for 3-5 days to obtain a soil-covered fruiting
bottle / bag; performing light culture on the soil-covered fruiting bottle / bag in a fruiting room, and spraying a
monopotassium phosphate solution during culture to promote mycelial growth and induce
primordium formation. The method can effectively promote rapid growth of Chinese saprophytic boletus hyphae in an
overburden layer, primordia are rapidly formed on the surface of the
overburden layer, and harvesting can be performed 13-15 days after
overburden.
