Flammulina velutipes culture medium and preparation method thereof

Abstract

The invention discloses a flammulina velutipes culture medium. The flammulina velutipes culture medium comprises raw materials in parts by weight as follows: 50-60 parts of corncob, 9-19 parts of bran, 5-8 parts of rice bran, 5-15 parts of oilseed rape meal, 5-15 parts of soybean hull, 1-2 parts of gypsum powder, 1-2 parts of shell fossil and 1-2 parts of peppermint oil. A preparation method of the flammulina velutipes culture medium comprises preparation of raw materials, bottling, sterilization and cooling, wherein preparation of raw materials comprises preparation of a dry material and preparation of a wet material; preparation of the wet material is as follows: a part of materials are mixed to sufficiently suck water, citric acid or pyruvic acid are added to adjust the pH value after alcoholic fermentation, then gypsum powder, shell fossil and a nutrition liquid are added, the mixture is treated on a shaking table at a constant temperature of 25 DEG C for 10-20 minutes, and the mixture is rotationally distillated for 1-2 hours till the water content is 50%-60%; and the cooled culture medium is used for inoculating flammulina velutipes. The flammulina velutipes culture medium is rich in iron, the use amount of rice bran and the cost are reduced, the water content in the culture medium is appropriate, and nutrition components are easy to absorb by flammulina velutipes.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a culture medium of Flammulina velutipes and a preparation method thereof. Background technique [0002] Flammulina velutipes is a kind of saprophytic fungus, and the nutrients needed for its growth and fruiting body development can only be obtained from the medium, so the nutritional composition, physical form, and water content of the medium have a huge impact on the growth of Flammulina velutipes. At present, rice bran is commonly used as a raw material for Flammulina velutipes cultivation, but the price has risen due to shortage of resources, and rice bran is rich in phytate, which is not conducive to the absorption of minerals. Corn cobs are rich in carbohydrates and cellulose, and are the best source of energy for the growth of Flammulina velutipes. Generally, the amount of corn cobs used is between 25% and 45%. For example, the Chinese inventi...

Problems solved by technology

[0004] As a high-protein animal, earthworm has good decomposition ability. Its movement can improve the quality of the matrix, make the matrix loose and maintain good air permeability. Metabolism into small molecular effective substances is more conducive to absorption, and it can also synthesize a series of active substances such as sugars, amino acids and vitamins. In addition to being widely used in pharmaceuticals, earthworms are also used to treat organic waste to promote the recycling of resources. The excrement is fine After air-drying, the crude ash content reaches more than 70%, among which the content of iron and manganese is relatively high. At present, there is no report on the use of earthworm activities to treat the medium to cultivate edible fungi
