The invention discloses a
Ganoderma lucidum
karst cultivation method for improving
ganoderma lucidum polysaccharides and
selenium content. The method comprises the steps of 1, preparation of a culture medium, wherein the culture medium is prepared from, by weight, 75 parts of
sawdust, 20 parts of wheat
bran, 2 parts of
corn flour, 1 part of
lime, 1 part of
gypsum and 1 part of
sugar, and the ratio of the materials to water is adjusted to 1:(1.3-1.5) with a
selenium-rich
nutrient solution; 2, material mixing, bagging, sterilization and
inoculation; 3, spawn running, wherein the inoculated culture medium is placed in a
greenhouse for spawn running, at the beginning, the
greenhouse temperature is controlled to be 26-28 DEG C, at the 20th day after
inoculation, the
greenhouse temperature is increased to be 34 DEG C and kept for 20-24 h, and then recovered to be 26-28 DEG C; 4,
ganoderma lucidum
karst germination, wherein after hyphae grow to be filled with the bag,
ganoderma lucidum
karst enters into a
ganoderma lucidum karst
germination period, and the greenhouse temperature is increased to be 34 DEG C at the 5th day, the 10th day, the 15th day and the 20th day in the
ganoderma lucidum karst
germination period respectively, kept for 20-24 h and then recovered to be 26-28 DEG C.
