Dictyophora rubrovalvata mother strain culture method

Abstract

The invention belongs to the technical field of edible fungus cultivation, and particularly relates to a dictyophora rubrovalvata mother strain culture method which includes the steps: (1) culture medium preparation: taking potatoes, glucose, malt sugar, yeast extract powder, peptone, bamboo plain soil, masson pine needles, coarse miscellaneous wood chips, fine wood chips and agar powder as raw materials by a certain weight to prepare a culture medium; (2) inoculation: selecting suitable strains, and inoculating the suitable strains onto the culture medium by an inoculation needle; (3) culture: culturing the inoculated culture medium under specific conditions for 20-25 days to obtain dictyophora rubrovalvata mother strains. The dictyophora rubrovalvata mother strain culture method is simple to operate, low in cost, free from pollution and short in growth cycle, and prepared dictyophora rubrovalvata mother strains are high in growth force and good in quality.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, in particular to a method for cultivating the mother species of Dictyophora edulis. Background technique [0002] Dictyophora, also known as bamboo fungus and bamboo ginseng, are common and edible. There are 4 kinds: long skirt bamboo fungus, short skirt bamboo fungus, spiny bamboo fungus and red bamboo fungus. Flower fungi are rich in nutrition, rich in fragrance and delicious in taste. They are called "Fairy in Snow Skirt", "Flower of Mountain Treasure", "Flower of Fungus" and "Queen of Fungi". Dictyophora edulis is a species with better quality among the edible ones. It has high medicinal value and nutritional value. It is the main species cultivated artificially in China. Excellent strains are the main prerequisite for obtaining high-quality Dictyophora edulis. However, the current Dictyophora spp. growth cycle is long, and there is a phenomenon that the activity of the bac...

Dictyophora edulis is a species with better quality among the edible ones. It has high medicinal value and nutritional value. It is the main species cultivated artificially in China. Excellent strains are the main prerequisite for obtaining high-quality Dictyophora edulis. However, the current Dictyophora spp. growth cycle is long, and there is a phenomenon that the activity of the bacteria is not strong; as disclosed in the document with the patent application number 201510841397.1, a method for cultivating the solid parent species of Dictyophora spp. uses sawdust, wheat Bran, corn flour, soybean flour, sugar, gypsum, and an appropriate amount of water are mixed and boiled for a period of time to make a culture medium. The mature bamboo eggs are used as the inoculation source, and the mother species of Dictyophora edulis is cultivated under specific conditions. The cultivation time is 35- 45 days, the cultivation time is relatively long; another example is a method for making the female species of Fanjingshan wild red-twisted bamboo fungus disclosed in the document with the patent application number 201510268986.5, which is made by mixing soil ginseng, rice, glucose, agar, and appropriate amount of water The culture medium uses the eggs of wild Dictyophora edulis in Fanjing Mountain as the inoculation source, and cultivates the mother species of Dictyophora edulis under specific conditions. The cultivation time is about 45 days, and the cultivation time is relatively long;
