Special culture medium for oudemansiella canarri (jungh.) hohnel and oudemansiella canarri (jungh.) hohnel cultivation method

Abstract

The invention provides a special culture medium for oudemansiella canarri (jungh.) hohnel. The special culture medium for oudemansiella canarri (jungh.) hohnel comprises a cultivation material culture medium, wherein the cultivation material comprises the following raw materials in percentage by weight: 45-50% of cotton seed hull, 30-35% of saw dust, 18-20% of bran, 1-2% of calcium carbonate and 1-2% of calcium sulphate. In addition, the special culture medium also comprises a mother strain separation culture medium, a mother strain production culture medium and a primary strain culture medium. The invention also provides an artificial cultivation method of oudemansiella canarri (jungh.) hohnel by using the culture medium. The method comprises the following steps: carrying out aseptic inoculation of primary strain of oudemansiella canarri (jungh.) hohnel to a cultivation material culture medium, culturing and producing mushrooms. The invention firstly provides the special culture medium for oudemansiella canarri (jungh.) hohnel with wide raw material sources and remarkable effect and provides an artificial domestication cultivation method using the special culture medium; the biotransformation rate reaches 110-130%. According to the cultivation method, the production period of mushrooms is short, large-scale application and popularization are convenient, and the economic values are high.

Description

technical field [0001] The invention belongs to the field of cultivation of rare edible fungi, and in particular relates to a special culture medium and a cultivation method of Oddella hazel. Background technique [0002] Oudemansiella canarii (Jungh.) Hohnel belongs to the Fungal Kingdom, the Phylum Fungi, Basidiomycotina, Phytomycetes, Agaricaceae, White Mushrooms, Oudemansiella genus, its fruiting bodies are generally medium and large, and the cap About 3-10cm in diameter, the surface is brown to tan, sticky when wet; the flesh is white; the gills are white to dirty white, relatively thin, unequal in length, straight to elongate, the fold margins are rough and brown to dark, and the stipe is often Curved, dirty white, with dark brown cilia and longitudinal stripes on the surface, soft to hollow inside; spores are ovoid, broadly ovoid to nearly spherical, about 12-23μm*10.5-18μm in size; frilled cysts up to 80- 150μm, the width can reach 12-40μm. Hazel Oddella often grow...

AI Technical Summary

Problems solved by technology

[0004] At present, there are few research reports on Oudemansiella canarii, mainly due to the difficulty of artificial cultivation, and the difficulty of large-scale collection in the wild due to factors such as region and season.

At present, only Wang Shouxian et al. (patent application No. 201210429491.2) have disclosed the cultivation method and special medium of Oddya halva in China about the domestication and cultivation of Oddya pheascus. The mass ratio of wheat bran and slaked lime is 50:30:18:2, which is mixed with water to make a fruiting medium with a water content of 65%-70% (mass percentage). The cultivation medium formula includes apple Branch sawdust is very limited, and the promotion of cultivation techniques will be limited
