Embodiment 1

[0022] The use of two types of industrial waste, cassava residue and vinegar residue, as raw materials in edible fungus culture medium.

[0023] Raw material pretreatment:

[0024] The cassava dregs and vinegar dregs are adjusted to a moisture content of 60%-70% by extrusion and dehydration.

[0025] Mixing ratio of raw materials:

[0026] The cassava residue and the vinegar residue are mixed in a ratio of 3-7:7-3 on a dry basis, and are evenly mixed by means of mechanical stirring or the like. Adjust the pH value of the raw material to about 7 with lime water.

[0027] Culture medium preparation, packaging:

[0028] The mixed material processed in the previous two steps is filled into the packaging bag (generally in the form of a fungus stick) for making edible fungus culture medium by mechanical or manual bagging. The diameter of the bacteria rod is 17-23 cm, and the length is not limited.

[0029] Sterilization:

[0030] The bacteria sticks of the packaging medium are...

Embodiment 2

[0032] The edible fungus culture medium bacteria stick product obtained in Example 1 is used for edible fungus cultivation, and the mycelium of the edible fungi to be cultivated is first inoculated, and after cultivation, different edible fungi are artificially punched in different parts of the fungus stick for fruiting .

[0033] Mushrooms, black fungus, etc. are artificially punched on the peripheral surface of the mushroom sticks to produce mushrooms.

[0034] Flammulina velutipes, Coprinus comatus, etc. produce mushrooms at one end of the mushroom stick.

[0035] Pleurotus ostreatus, xiuzhen mushroom, tea tree mushroom, etc. produce mushrooms at the two ends of the fungus stick.

[0036] Taking Pleurotus ostreatus as an example, the cultivation time is 25-30 days, and the production of Pleurotus ostreatus per kg is 1.8-2kg based on the dry basis of the culture medium in the mushroom stick.

Abstract

A method for producing superior edible fungi culture medium by using manioc waste and acid-sludge as raw materials, belonging to the technical field of comprehensive utilization of the manioc waste and the acid-sludge, and edible fungi cultivation. In the invention, the manioc waste and the acid-sludge, two common leftover bits and pieces in fermentation and food industries, are scientifically compounded to serve as edible fungi culture medium, and the invention can be used for the production of all edible fungi culture media. The invention, on the basis of reducing culture medium raw material cost by over 50%, can shorten the culture period by 10-20% and increase the yield by 20-30%. The method resolves the problems of current low utility ratio of the manioc waste and the acid-sludge, serious environment pollution and the like, converts waste into treasure, and has high social and economic benefits.

Description

technical field [0001] The invention discloses a method for producing high-quality edible fungus medium by using cassava residue and vinegar residue as raw materials, and belongs to the technical fields of comprehensive utilization of cassava residue and vinegar residue and cultivation of edible fungi. Background technique [0002] The invention is a technology aimed at producing high-quality edible fungus culture medium in the technical field of agricultural production. Edible fungi are large fungi that are eaten by humans. There are more than 350 kinds of edible fungi known in China, most of which belong to Basidiomycotina. Door, including: morel, saddle mushroom, truffle, etc. The above-mentioned fungi grow in different regions and in different ecological environments. There are many types and quantities that grow in mountainous forests, such as shiitake mushrooms, fungus, white fungus, Hericium erinaceus, matsutake mushrooms, red mushrooms and boletus. On the fields,...
