However, in the process of tea production every year, there will be a large number of pruned and discarded tea tree branches and leaves left after picking tea leaves, plus the tea dregs after people drink tea, which are all called tea waste. It is discarded as garbage, which not only increases the amount of garbage disposal, but also fails to recycle these valuable organic resources

Embodiment 1

[0082] The preparation method of the edible fungus culture medium with tea tree branches and leaves as the main material, the tea tree branches and leaves are cut into pieces, weighed in bags for later use, and the weight ratio of each additive is as follows: tea waste 97%, gypsum 2%, urea 1%, cottonseed Shell 0%. All the ingredients are mixed in water and then added to the chopped tea tree branches and leaves and stirred evenly. Sterilize in a high-pressure steam sterilizer at a temperature of 121° C. for 30 minutes. The cultured mushrooms grow rapidly, the dry weight of the culture medium is 1kg, the mass of the mushrooms is 1842.1g, and the biological transformation rate is about 184%.

Embodiment 2

[0084] The preparation method of the edible fungus culture medium with tea tree branches and leaves as the main material comprises cutting the tea tree branches and leaves into pieces, and weighing them in separate bags for later use. The weight ratio of each additive is as follows: 96% of tea waste, 1% of urea, 1% of gypsum, 1% of calcium superphosphate, and 1% of cotton seed hulls. Gypsum, urea, and superphosphate are mixed in water evenly, then add chopped tea tree branches and leaves and cottonseed hulls, and stir evenly. The mixture was sterilized in a high-pressure steam sterilizer at a temperature of 121° C. for 30 minutes. The cultured mushrooms grow rapidly, the dry weight of the medium is 1kg, the quality of the mushrooms is 1704.2g, and the biological conversion rate is about 170.4%.

Embodiment 3

[0086] The preparation method of the edible fungus culture medium with tea tree branches and leaves as the main material comprises cutting the tea tree branches and leaves into pieces, and weighing them in separate bags for later use. The weight ratio of each additive is as follows: 75% of tea waste, 1% of gypsum, 1% of urea, 1% of calcium superphosphate, and 22% of cotton seed hulls. Gypsum, urea, and superphosphate are mixed in water evenly, then add chopped tea tree branches and leaves and cottonseed hulls, and stir evenly. The mixture was sterilized using a high-pressure steam sterilizer at a temperature of 121° C. for 30 minutes. The cultured mushroom grows rapidly, the dry weight of the culture medium is 1kg, the quality of the mushroom is 1988.8g, and the biological transformation rate is about 199%.

Abstract

The invention relates to an edible fungus culture medium with tea waste as the main raw material. The composition and weight percentage of the total dry material of the culture medium are: 75%-97.5% of tea waste, 0-22% of cotton seed hulls, 0-5% of urea, 0-5% of superphosphate, 0-5% of gypsum, and 0-0.5% of potassium permanganate. The tea waste is shredded for pretreatment, and urea, superphosphate, Gypsum and potassium permanganate are dissolved in appropriate amount of water, poured into the treated tea waste and cottonseed hulls, and stirred evenly to obtain a culture medium for edible fungi. The present invention selects the optimal culture medium for cultivating shiitake mushrooms, oyster mushrooms and enoki mushrooms through optimization experiments; the output ratio of the quality of tea waste to the cultivated edible fungi is 1:1.8-2.5. The invention not only solves the difficult problem of tea waste treatment, but also improves the efficiency of organic resource reuse, and is also conducive to improving the economic benefits of tea-producing areas.

Description

technical field [0001] The invention relates to an edible fungus culture medium with tea waste as the main raw material, which is suitable for cultivating oyster mushrooms, shiitake mushrooms, enoki mushrooms and other edible fungi. Background technique [0002] Tea has a long history in China and has many uses. Tea is a fine beverage that our Chinese nation has drunk for a long time, and its influence is extremely far-reaching. my country is also a big tea-producing country, and a large amount of tea will be produced every year. However, in the process of tea production every year, there will be a large number of pruned and discarded tea tree branches and leaves left after picking tea leaves, plus the tea dregs after people drink tea, which are all called tea waste. It is discarded as garbage, which not only increases the amount of garbage disposal, but also fails to recycle these valuable organic resources. At the same time, the prices of agricultural and sideline produc...
