Ganoderma lucidum karst cultivation method for improving ganoderma lucidum polysaccharides and selenium content

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of edible mushroom cultivation, in particular to a ganoderma cultivation method for increasing the content of ganoderma polysaccharides and selenium. Background technique [0002] Ganoderma lucidum (scientific name: Ganoderma Lucidum Karst), also known as Ganoderma lucidum grass, fairy grass, also known as red lucidum, red lucidum, wood ganoderma, fungus ganoderma, perennial mushroom, ganoderma grass, is the whole plant of polyporaceae red lucidum or purple lucidum. The fruiting body of the fungus Ganoderma lucidum. The shape is umbrella-shaped, and the cap is kidney-shaped, semicircular or nearly circular. Ganoderma lucidum is a precious traditional Chinese medicinal material with a history of thousands of years of medicinal use. It has the effects of invigorating qi and calming the nerves, relieving cough and relieving asthma. Ganoderma lucidum has high medicinal value. After decades of modern pharmacolo...

AI Technical Summary

Problems solved by technology

[0005] However, the number of naturally grown Ganoderma lucidum is small, and contains a large amount of crude fiber and other impurities, and the polysaccharide content of Ganoderma lucidum is not high (usually 2-5%), so it is not convenient to be directly used as health food or raw material of medicine. Therefore, development can improve the quality of Ganoderma lucidum The artificial cultivation and cultivation technology research of Ganoderma lucidum with polysaccharide and selenium content is the key to the industrialization of Ganoderma cultivation
