Problems solved by technology

The development of the edible fungi industry meets the needs of people's consumption growth and sustainable agricultural development, and is an effective way for farmers to get rich quickly. As the market demand for edible fungi increases, the planting area continues to increase, and conventional planting raw material resources are becoming more and more It is urgent to find new raw materials to replace or supplement the existing raw material resources. At the same time, the mushroom body absorption rate in the existing edible fungi cultivation technology is low, resulting in high cost and poor taste. For example, the publication number is : CN104557258A (2015-04-29) discloses a method for preparing edible fungus cultivation substrate by using potato dregs. Although the local source of culture raw materials has been solved, the taste of the cultivated edible fungi needs to be improved

preparation example Construction

[0031] The preparation method of the white tea trimmed branches and leaves comprises: taking the white tea trimmed branches and leaves, drying the white tea trimmed branches and leaves, and cutting the dried white tea trimmed branches and leaves with a shearing machine, so that the white tea trimmed branches and leaves are between 0.5-2 cm, and the white tea is made Trim the ends of the leaves.

[0032] Preparation method 1 of white tea powder includes: take white tea and put it in a desiccator, dry it at 80°C for 10 minutes, then take it out and quickly cool it to -35°C, the freezing time is 3 hours, then warm it up to room temperature, take it the next day, and process it Good white tea is put into a grinder for grinding, passed through a 200-mesh sieve, and then made into white tea powder.

[0033] Preparation method 2 of white tea powder includes: put the white tea in a desiccator, dry it at 100°C for 40 minutes, then take it out and quickly cool it to -10°C, the freezing ...

Embodiment 1

[0041] A method for cultivating an edible fungus cultivation substrate, comprising the following steps:

[0042](1) Weigh sawdust, white tea pruned branches and leaves, white tea powder, wheat bran, gypsum powder and sucrose in formula 1 in proportion, stir evenly, then add 55% of the total mass of water and mix evenly to obtain a mixture;

[0043] (2) Take the mixture in step (1) and put it into a bag, control the weight of the wet material of the mixture to 1kg, compact it, and then perform sterilization treatment to obtain a sterilization bag;

[0044] (3) Cool the sterilization bag in step (2), then punch the inoculation hole in the sterilization bag, then insert the original species of edible fungus in the inoculation hole, and seal the inoculation hole with a sterile rubber strip after inoculation to obtain Edible mushroom sticks;

[0045] (4) Place the mushroom sticks in step (3) in an environment of 26°C for cultivation. When the color of the mycelium turns brown, cut...

Embodiment 2

[0049] The cultivation method of edible mushroom cultivation substrate is the same as embodiment 1, and difference is:

[0050] Step (1) Weigh the ingredients according to the proportion of formula 2, then add 58% water by mass and mix evenly to obtain a mixture;

[0051] Step (2) Control the weight of the wet material of the mixture at 0.8kg, compact it, and then perform sterilization treatment to obtain a sterilization bag;

[0052] Step (4) is to put the edible fungus sticks of shiitake mushrooms in step (3) in an environment of 22°C for cultivation. When the color of the mycelium turns brown, cut the bag in step (2), and carry out the mycelium and culture substrate. Remove the bag and discharge, and then focus on greenhouse cultivation.

[0053] The sterilization method in step (2) is high pressure sterilization, and the volume in step (2) is 0.5-1m 3 Put the sterilization bag into the autoclave, then pressurize to 1.5 atmospheres and keep it for 50min, and finally turn ...

Abstract

The invention relates to a culture medium for edible mushrooms. The culture medium comprises the following ingredients (by weight): 15-70 parts of sawdust, 4-23 parts of trimmed branch and leaf powder of white tea, 1-7 parts of white tea powder, 18-25 parts of wheat bran, 0-2 parts of gypsum powder and 1-2 parts of cane sugar. The culture method of the culture medium for edible mushrooms comprises the following steps: 1, weighing the above ingredients in proportion and uniformly stirring, adding water and uniformly mixing; 2, putting the mixture into a bag and pressing, and carrying out sterilization treatment; 3, cooling, punching the sterilization bag to form inoculation holes, inoculating culture spawn for edible mushrooms into the inoculation holes, and sealing the inoculation holes with an aseptic adhesive tape; and 4, culturing in an environment of 22-26 DEG C, cutting off the bag after culture, discharging mycelia and the culture medium out of the bag, and culturing together in a greenhouse. Edible mushrooms obtained by the use of the culture medium have good mouthfeel, have thicky texture, have fragrance and have high edibleness.

Description

technical field [0001] The invention relates to the field of a cultivation substrate and a cultivation method of edible fungi, in particular to a cultivation substrate and a cultivation method of edible fungi. Background technique [0002] Edible mushrooms refer to edible mushrooms, commonly known as mushrooms. There are more than 350 kinds of edible fungi known in China, most of which belong to Basidiomycotina. Cordyceps, truffles, lark and boletus, etc.; a few belong to the subphylum Ascomycota, including morels, saddle mushrooms, truffles, etc. Edible fungus cultivation, as a good project with small investment, short cycle and quick results, has developed rapidly in China, and edible fungus products were once in short supply. The edible fungus industry is a short-term and fast rural economic development project integrating economic benefits, ecological benefits and social benefits. Edible fungi are also a kind of organic, nutritious and healthy green food. The developm...
