Lucid-ganoderma cultivation method for increasing ganoderan and selenium content

Abstract

The invention discloses a lucid-ganoderma cultivation method for increasing the ganoderan and selenium content. The lucid-ganoderma cultivation method includes the steps of 1) medium preparing, wherein a medium is prepared from, by weight, 75 parts of wood flour, 20 parts of wheat bran, 2 parts of corn flour, 1 part of lime, 1 part of gypsum and 1 part of sugar, the ratio of a material to water is adjusted by selenium-rich nutrient liquid to be 1:(1.3-1.5); 2) material stirring, bagging, sterilizing and inoculating; 3) spawn running, wherein after inoculating is carried out, lucid ganoderma is put into a greenhouse and subjected to spawn running, at first, the temperature of the greenhouse is controlled to be 26 DEG C to 28 DEG C, and on the 20th day after inoculating is carried out, the temperature of the greenhouse is increased to be 34 DEG C, the temperature is kept for 20 h to 24 h, and then the temperature of the greenhouse is recovered to be 26 DEG C to 28 DEG C; 4) lucid ganoderma discharging, wherein after hyphas overgrows a bag, the lucid ganoderma enters the lucid ganoderma discharging stage, the temperature of the greenhouse is increased to be 34 DEG C on the 5th day, the 10th day, the 15th day, the 20th day and the 25th day of the lucid ganoderma discharging stage of the lucid ganoderma respectively, the temperature is kept for 20 h to 24 h, and then the temperature of the greenhouse is recovered to be 26 DEG C to 28 DEG C.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a ganoderma cultivation method for increasing the content of ganoderma lucidum polysaccharide 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 pharm...

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
