Problems solved by technology

In recent years, the prices of raw materials such as rice bran, bran, and corncobs, which are the main raw materials for edible fungus cultivation, have also been rising. Sawdust needs to be sprayed and accumulated for a long time before use, which not only takes up a lot of space, but also causes environmental problems due to the sprayed water. Cottonseed hulls widely used in edible mushroom cultivation have the risk of enriching pesticides and heavy metals

Embodiment 1

[0033] Preparation of distiller's grain compound medium: the components in the medium and the mass parts of each component are as follows: 5 parts of distiller's grains, 35 parts of rice bran, 8 parts of bran, 37 parts of corncobs, 5 parts of corn flour, and 6 parts of beet pulp 1 part, 3 parts of shell powder, 1 part of light calcium carbonate.

[0034] Put various raw materials into the mixer in turn, first dry mix for 10 minutes, then add water and stir until the various raw materials in the culture medium are mixed evenly and fully absorb water. The water content of the culture medium is required to be 66% to 68%, and the pH is 6.2 to 6.8 .

[0035] Every 16 polypropylene plastic cultivation bottles are a basket, and the prepared compound culture medium is filled into the cultivation bottles by a fully automatic bottling machine. There should be a hole to the bottom of the bottle, and the surface of the culture medium is required to be flat. The capacity of the cultivatio...

Embodiment 2

Abstract

The invention discloses a distiller grain composite culture medium and an application thereof in factory-like white needle mushroom cultivation. The culture medium comprises the components in part by mass of 5-20 parts of distiller grains, 30-40 parts of rice bran, 5-10 parts of bran, 30-40 parts of corncob, 3-5 parts of corn flour, 5-10 parts of sugar beet pulp, 1-3 parts of shell powder and 1-3 parts of light calcium carbonate, the moisture content is 66% to 68%, and the pH is 6.2 to 6.8. The distiller grain composite culture medium has the advantages that the granularity of the culture medium is uniform, the breathability is good, the growth speed of hypha is rapid, and the culture period is short. Compared with a traditional needle mushroom culture medium and a culture manner, the production period can be shortened by 2-8 days, the average per unit yield is improved by 50-100 g, the uniformity and the whiteness are good, and the product appearance is improved greatly.

Description

technical field [0001] The invention relates to a distiller's grain compound medium and its application in industrial cultivation of Flammulina velutipes, belonging to the technical field of industrial cultivation of edible fungi. Background technique [0002] Distiller's grains are a by-product of brewing. They are brown in color, have the taste of fermentation products, and have a slightly toasted and malty flavor. elements, of which the content of lysine, methionine and tryptophan is also very high. The brewing industry has done a lot of research on the utilization of solid distiller's grains, such as: making distiller's grain dry feed, distiller's grain silage, distiller's grain bacterial protein feed, distiller's grain feed additives, distiller's grains to produce indirect animal protein feed, etc. Fundamentally solve the problem of the final direction of distiller's grains. Because no effective utilization method has been found, the current price of distiller's grain...
