Preparation method of original boletus edulis strains

Abstract

The invention discloses a preparation method of original boletus edulis strains. The original boletus edulis strains are prepared through the steps that a specific original boletus edulis strain culture medium is prepared from fresh pine needles, peeled potatoes, boletus edulis locality soil, tryptone, carbamide, a beef extract, vitamin B1, dipotassium hydrogen phosphate, ferrous sulfate, calcium chloride, glucose, chloramphenicol, granular active carbon, granular mature boletus edulis sporophores, gibberellin and the like, and then culture medium sterilizing, inoculating and strain culturing are conducted. Compared with the prior art, the preparation method of the original boletus edulis strains has the quite outstanding advantages that simpleness is achieved, and the stains are pure; the production cost can be reduced by 10%-15%; strain contamination can be reduced by 25% or above; the mycelium biomass (136.42 mg / kg) is increased by 25 mg / kg or above compared with a traditional method, and the infection intensity (75%) of the strains on trees can be improved by 20% or above compared with the traditional method.

Description

technical field [0001] The invention relates to the technical field of producing edible and medicinal fungus strains, in particular to a method for producing the original species of delicious boletus. Background technique [0002] Delicious boletus (Boletus edulis) is also known as bigfoot mushroom and white boletus. Fruiting bodies are medium to large. The cap is flat hemispherical or slightly flattened, non-sticky, smooth, with pure edges, yellowish brown, earthy brown or reddish brown. The flesh of the bacteria is white, thick, and does not change color after injury. Fungal tubes are initially white, then pale in color, straight or nearly twinned, or sunken around the stalk. The mouth of the tube is round, the base is slightly enlarged, light brown or light yellowish brown, and the inside is solid. [0003] Delicious boletus grows in mountainous areas of 600-1500m. It is a high-temperature fungus. The optimum temperature for mycelium growth is 23-28°C. Generally, it g...
