Embodiment 1

[0028] Embodiment 1 discloses a cultivation method for improving the polysaccharide content of shiitake mushroom mycelia, including base material treatment (gingko biloba residue treatment), base material preparation, bagging, high-temperature sterilization, inoculation, mycelium cultivation, and mycelium collection process steps,

[0029] Base material treatment: first crush the ginkgo leaf residue weighed in step 1 into a size of 0.3-0.5 cm, add wood chips in proportion and add 1-2% cellulase by weight, and perform biodegradation treatment to prepare the base material;

[0030] Base material preparation: Weigh the main material and auxiliary materials according to the formula ratio, stir evenly, add water in an appropriate amount to achieve a suitable material-water ratio, and then carry out the bagging step; bagging: put the prepared cultivated mushroom base material into a special film In the tube, seal it to make cultivation sticks of mushroom mycelium; high temperature s...

Embodiment 2

[0034] Embodiment 2 has the same operation steps as in Example 1, the difference is that in Example 2, a biological growth regulator is added in the base material preparation and inoculation process, and the biological growth regulator is composed of oleic acid and α-naphthaleneacetic acid, and the base material In the preparation step, the components (weight) of the base material are: 65 parts of ginkgo biloba, 15 parts of sawdust, 10 parts of bran, 0.5 part of urea, 1.5 parts of white sugar, 1 part of superphosphate, and 0.8 part of gypsum; Add 0.3 parts of oleic acid to the mixture, stir evenly and then carry out the bagging step. Before the inoculation step begins after the high-temperature sterilization step ends, inject 0.03 parts of α-naphthalene acetic acid at the inoculation port, and then perform the inoculation step, wherein the depth of biological growth regulator injection is 2 / 3 of the thickness of the bacterial rod . The polysaccharide content in the mushroom m...

Embodiment 3

[0036]Embodiment 3 takes the same cultivation steps as in Example 1, the difference is that in the present embodiment, a biological growth regulator is added in the base material preparation and mycelia cultivation steps, and the biological growth regulator is composed of oleic acid and 3-indole Butyric acid; in the base material preparation step, the component (weight) of base material is: 60 parts of ginkgo biloba residues, 20 parts of sawdust, 5 parts of bran, 0.0 part of urea, 1.2 parts of white sugar, 1.2 parts of superphosphate, gypsum 1 part, and 0.4 part of oleic acid was added to the base material at the same time; after the main material and auxiliary materials were accurately weighed according to the formula ratio, they were repeatedly stirred evenly, and an appropriate amount of water was added to achieve a suitable material-water ratio, and then the bagging step was carried out; In the cultivation step, when the mycelium of the bacterium stick is overgrown and the ...

Abstract

The invention discloses a cultivation method capable of improving the content of polysaccharides in shiitake mushroom hyphae. The cultivation method comprises the following steps: treating a base material, preparing a matrix material, bagging, sterilizing at high temperature, inoculating and culturing the hyphae. A biological growth regulator is added in any one or any two of steps of preparing the matrix material, inoculating and culturing the hyphae; the biological growth regulator is formed by combining any one or two of oleic acid, alpha-naphthylacetic acid and 3-indolebutyric acid. By adopting the the cultivation method capable of improving the content of the polysaccharides in the shiitake mushroom hyphae, disclosed by the invention, the value of the shiitake mushroom hyphae can be improved; meanwhile, waste ginkgo leaf residues obtained by manufacturing enterprises of ginkgo leaf extract are sufficiently utilized, so that the production cost of mushroom growers is reduced and the income is improved; the cultivation method further has the characteristics of simplicity in operation technology, convenience for operation and capability of sufficiently utilizing resources.

Description

technical field [0001] The invention relates to a cultivation method for edible fungi, in particular to a cultivation method for increasing the polysaccharide content of shiitake mushroom mycelium by using ginkgo leaf residue. Background technique [0002] Lentinus edodes, also known as Xianggu, Xiangxin, Xianggu, Shiitake, belongs to the genus Lentinus genus of Basidiomycetes Agaricaceae Pleurotaceae. Lentinus edodes is a famous fungus with both food and medicine. It has a strong fragrance and rich nutrition. It contains 18 kinds of amino acids, 7 of which are Necessary for the human body. The ergosterol contained in it can be converted into vitamin D, which has the effect of enhancing the body's resistance to diseases and preventing colds; lentinan has anti-tumor effects; adenine and choline can prevent liver cirrhosis and vascular sclerosis; tyrosine oxidase can lower blood pressure Efficacy; double-stranded ribonucleic acid can induce interferon production and has antiv...
