Method for preparing culture medium of beech mushrooms and needle mushrooms by utilizing waste material of agaric culture medium

Abstract

The invention provides a method for preparing a culture medium of beech mushrooms and needle mushrooms by utilizing a waste material of an agaric culture medium. The method comprises the following steps: (1) collecting and materializing treatment for the waste material of the agaric culture medium: selecting a qualified fungus bag for debagging, crushing under tiny wet state, adding a modifier while crushing to adjust a pH value to be 6.0-7.0, and standing in sunlight for exposing 2-8 days or drying for 6-12 hours at 65-75 DEG C until the water content is 10%-13% for later use, and (2) nutrient balancing preparing for the culture medium: taking 65-75% of processed agaric waste materials, 10-25% of bran or rice bran, 2% of bean flour, 5-10% of corn flour, 0.5% of white sugar, 1-2% of calcium superphosphate or potassium phosphate, 1-2% of gypsum and 0.5-1% of magnesium sulfate, and then adding water until the water content is 55%-65%, and uniformly stirring after an absorbing nutritional solution of 0.3-2.5% nutritional type biopolymer is saturated. According to the method, the cost is low, the yield is high, the waste is efficiently reused and the environmental pollution is reduced.

Description

technical field

[0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a method for preparing culture substrates of crab-flavored mushrooms and enoki mushrooms by using waste materials of agaric culture medium as main components. Background technique

[0002] At present, large-scale cultivation of fungus has been realized in most parts of the country in my country, so the waste of fungus culture medium has a large output and is cheap and easy to get. The waste after cultivating fungus is often discarded in the field or burned, causing great environmental pollution and waste of resources.

[0003] Crab-flavored mushrooms and Flammulina velutipes are two kinds of edible fungi that are popular with the public, have high nutritional value and high economic benefits, and have broad market prospects. At present, the main components of the culture medium (cultivation medium) of crab-flavored mushrooms, enoki mushrooms and fun...
