Embodiment 1

[0039] The preparation method of Pleurotus ostreatus culture medium with tea resources as the main ingredient. The summer and autumn tea is mixed with a material-to-water ratio of 1:20, subjected to constant temperature and constant heat treatment at 70°C for 2 hours, centrifuged at 1000r / min to leave residue, and dried for later use. The weight ratio of each additive is as follows: 80% of summer and autumn tea treatment slag, 18% of bran, 1% of calcium carbonate, and 1% of dextrin. All ingredients are mixed evenly in a 500r / min mixer. The mixture is sterilized by hot pressing, and the conditions are as follows: the hot pressing pressure is 0.1 MPa, the hot pressing time is 4 hours, and the hot pressing temperature is 120°C.

[0040] The cultivated Pleurotus ostreatus sporocarp mycelium grows rapidly, and it takes 28 days from inoculation to harvesting, and the bioavailability of single wet mushroom reaches 35%.

Embodiment 2

[0042] The preparation method of the culture medium of Flammulina velutipes as the main material is tea resources, and the leftovers in the deep processing of tea can be used directly without treatment. The weight ratio of each additive is as follows: leftovers in tea deep processing 60%, bran 30%, calcium carbonate 2%, dextrin 8%. All ingredients are mixed evenly in a 500r / min mixer. The mixture is sterilized by hot pressing, and the conditions are as follows: the hot pressing pressure is 0.15 MPa, the hot pressing time is 3 hours, and the hot pressing temperature is 115°C.

[0043] The cultivated Flammulina velutipes mycelium grows vigorously, and the primordium is neat and dense. It takes 52 days from inoculation to harvesting. The single-moisture bioavailability of the harvested Flammulina velutipes reaches 35%. Flammulina velutipes is delicious and nutritious. See Table 1 for details.

[0044] Table 1 uses the above-mentioned medium to cultivate the nutrient composition an...

Embodiment 3

[0046] The preparation method of Ganoderma lucidum culture medium with tea resources as the main material, the pruned branches and leaves of the tea garden are mixed at a material-water ratio of 1:10, subjected to constant temperature and constant heat treatment at 60°C for 2 hours, centrifuged at 1000r / min to leave residue, and dried for later use. The weight ratio of each additive is as follows: 70% of trimmed branches and leaves of tea garden, 25% of bran, 3% of calcium carbonate and 2% of dextrin. All ingredients are mixed evenly in a 500r / min mixer. The mixture is sterilized by hot pressing, and the conditions are as follows: the hot pressing pressure is 0.1 MPa, the hot pressing time is 4 hours, and the hot pressing temperature is 120°C.

[0047] The cultured ganoderma lucidum mycelium grows well, and it takes 50 days from inoculation to harvest.

Abstract

The invention discloses an edible fungus culture medium using tea resources as main materials. The edible fungus culture medium consists of the following raw materials in percentage by weight: 60 to 80 percent of tea resource, 10 to 30 percent of quick nutrient source, 1 to 8 percent of pH value regulator, and 2 to 8 percent of functional water binding agent. The invention also discloses a preparation method for the edible fungus culture medium. According to the method, the activation of antigrowth factors and a sterilization process of base stock are used as key technologies, and the tea resources such as autumn and summer tea which is not harvested, trimmed branches and leaves in waste tea gardens, and a great amount of tea deep processing byproducts are treated. The invention also discloses the application of the edible fungus culture medium; and the edible fungus culture medium is mainly applied to the culturing of edible fungi such as mushrooms, agaric, and glossy ganoderma, so that the resources in different industries are efficiently integrated, the environment stress is relieved, and the low-carbon, high-efficiency and practical effects are achieved.

Description

technical field [0001] The invention relates to an edible fungus culture medium and a preparation method thereof, in particular to an edible fungus culture medium with tea resources as the main ingredient and a preparation method thereof. Background technique [0002] In recent years, with the development of tea deep-processing technology and the development of tea deep-processing products, a large amount of tea resource waste has been produced, such as tea dregs, high-grade tea and tea product processing waste, low-grade tea, etc. A large number of discarded summer and autumn teas and pruned tea branches and leaves are produced. These unused tea resources not only brought serious pressure to the ecological environment, but also caused a huge waste of resources. There are still a lot of nutrients in these tea resources, for example, 17%-19% of crude protein, 16%-18% of crude fiber, 1%-2% of tea polyphenols remain in the extracted tea dregs. Phenol has high potential utiliz...
