From the paper

Abstract

The present invention provides a formula of high-yield flammulina velutipes culture medium and a producing technique thereof. The invention relates to the technical filed of biological strain, and specially to the formula of high-yield flammulina velutipes culture medium and producing technique thereof. The corncob is used as main ingredient for replacing fir sawdust. The invention adopts 40-45% of corncob, 10-12% of bagasse, 25-30% of rice bran, 8-10% of bran, 4-6% of soybean hull and 2-3% of corn flour as the raw materials of flammulina velutipes culture medium. The method comprises the techniques of dry mixing, wet mixing, etc. The pH value is controlled between 7.0 and 7.5. The cultured flammulina velutipes has the advantages of strong activity of mycelium, high production volume, ordered mushroom generation, excellent commodity valve, ordered growing of sporphore, uniform magnitude of bonnet, white color, and no infection of foreign fungus. The unit production obtains 286-293grams/bottle. The dry object of each bottle is 260grams. The biological transformation efficiency reaches up to 110-113% and is increased for 30-40% compared with the common formula. The economic benefit is excellent.
