Abstract

The invention relates to the technical field of cultivation of edible mushrooms and particularly relates to a method for preparing a culture medium for an edible mushroom. The method mainly comprises the following steps: processing walnut shells, firstly pulverizing the walnut shells into particles of which the diameter is less than 8mm by virtue of a high-speed pulverizer, placing the pulverized walnut shells into a high-pressure reactor equipped with ultrasonic waves and adding water of which the mass is 2.5-5.5 times of mass of the walnut shells, introducing nitrogen so that the pressure inside the reactor is 1.2MPa-15.5MPa, starting an ultrasonic generator, carrying out ultrasonic radiation for 5-45 minutes at room temperature, dehydrating and airing for later use. According to the method disclosed by the invention, by adopting a high-pressure ultrasonic irradiation method, the dissolution rate of tannin having inhibiting effect on the growth of the mushroom in the walnut shells is accelerated, the soaking time is reduced, the working efficiency is improved; the yield of the edible mushroom is increased by 18%-35% than the yield of the edible mushroom cultured by virtue of the traditional soaking medium, the production cost is significantly reduced and the market competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a preparation method of an edible fungus culture substrate. Background technique [0002] Walnut, deciduous tree, odd-pinnate compound leaves, leaflets elliptic, drupe spherical, exocarp smooth, endocarp hard, wrinkled, brain-shaped. It belongs to the seed plant family. The wood is tough and can be used as utensils. The nuts can be eaten, pressed for oil, and used as medicine. It is not only delicious, but also has high nutritional value. It is known as "longevity fruit" and "longevity fruit". Walnut shell is the endocarp. It is a kind of granular filter material with microporous surface and good adsorption effect after degreasing, crushing and screening. It is also a natural rolling material and polishing abrasive. Use it as abrasive It will not damage the surface of the workpiece, and the polishing effect is good. Its chemical properties are stable, and its ...
