Problems solved by technology

Because its stipe grows in the middle, and belongs to the large fungus of the genus Pleurotus, it is named Pleurotus stipe in the present invention. Since the discovery of Pleurotus stipe, after many years of searching, there is no report of the discovery of this fungus, and artificial cultivation Methods There are no similar studies reported in the literature

Embodiment Construction

[0023] Side ear of the present invention ( Pleurotus sp. ) P26297 is collected from wild saprophytic fungi in natural forest farms as specimens, and domesticated by tissue separation method.

[0024] During the domestication process, the isolated strains are placed in various environments (different C / N ratios, temperature, pH, light, etc.) for bacterial culture and fruiting, so that the mycelium grows densely, and the mycelia are lined in the later stage. The strain with relatively stable genetic performance was used as the mother species. The specific screening process is as follows:

[0025] The sparse hyphae obtained from tissue separation were cultured for multiple generations at different temperatures, and it was found that at 22°C, the mycelium grew fastest and the mycelium was thick. Through the selection of various carbon sources and nitrogen sources, 1% peptone was added to the basal medium. The tested carbon sources are: maltose, starch, lactose, fructose, sucros...

Abstract

The invention provides an artificial culture strain of wild edible fungi and a culture method of the artificial culture strain. The artificial culture strain of the wild edible fungi is Pleurotussp. P26297; and the collection number of the strain is CGMCC No.4908. By using the Pleurotussp. P26297 as a parent strain, the culture method comprises breeding, fungi growth, fruiting management and fungi picking. The artificial culture strain of the wild edible fungi is obtained by collection of wild saprophytic bacteria and artificial domestication, germplasm resource of the species is protected, anew variety of the edible fungi is developed, the variety structure of the edible fungi is regulated, market variety supply of the edible fungi is enriched, and the strain has relatively high economic and social benefits.

Description

technical field [0001] The invention relates to an artificially cultivated strain of wild edible fungus and a cultivation method thereof. Background technique [0002] Wild edible fungi are wild fungi that grow in natural forests and are completely wild in nature. They are mainly divided into two types, saprophytic fungi and mycorrhizal fungi. Mycorrhizal fungi cannot be artificially cultivated so far, while saprophytic fungi can be cultivated through Artificial domestication, artificial cultivation, but also factory cultivation. The applicant has collected a strain of wild fungus from a natural forest farm, and after being domesticated many times, it can now be artificially cultivated. According to the morphological characteristics, the cultivated strain was preliminarily determined to be Pleurotus genus. Because its stipe grows in the middle, and belongs to the large fungus of the genus Pleurotus, it is named Pleurotus stipe in the present invention. Since the discov...
