High-yield strain production cultivation method of golden fungus

Abstract

The invention discloses a high-yield strain production cultivation method of golden fungus. The high-yield strain production cultivation method comprises the following steps: preparing a mother strain culture medium, sterilizing the mother strain culture medium, preparing mother strains, preparing a stock (cultivation strain) culture medium, preparing stock (cultivation strain) inoculation and cultivating with materials for substitutes. A formula of the mother strain culture medium of the golden fungus is prepared from (peeled) potato, sucrose, potassium dihydrogen phosphate, magnesium sulfate, agar and water at the ratio of 20 to 3 to 0.3 to 0.15 to 100. A formula of a stock (cultivation strain) culture medium is prepared from 80 percent of broad-leaved tree sawdust, 16 percent of corn flour, 2 percent of sucrose, 1 percent of potassium dihydrogen phosphate and 1 percent of gypsum. By carrying out two times of strain preparation (mother strain preparation and stock preparation), the golden fungus and accompanying stereum hirsutum are separated and are cultured respectively, so as to obtain a golden fungus mixed stock. In a cultivating process, the germination of strains is rapid and material consumption is rapid; the pollution rate is low and a color changing speed is rapid; the growth period is short.

Description

technical field [0001] The invention belongs to the field of edible fungus cultivation, and in particular relates to a method for high-yield seed production and cultivation of golden ear. Background technique [0002] Golden ear (Tremella aurantialba Bandoni et Zang), is a fungus of the fungal plant phylum, also known as yellow fungus, Maoruo Serbu (Tibetan), golden white fungus, yellow ear, and brain ear. Golden ear is rich in fat, protein and trace elements such as phosphorus, sulfur, manganese, iron, magnesium, calcium, potassium, etc. It is a nutritional tonic and can be used as medicine. The nourishing nutritional value of golden ear is better than that of white fungus, black fungus and other colloidal fungi, and it is an ideal high-grade rice dumpling delicacy and health care product. [0003] Since the fruiting body of golden ear is heterogeneous, it is a complex composed of golden ear and hard leathery bacteria (hair stellate bacteria), and its excellent strain must...

Problems solved by technology

[0005] In the actual production process, due to the poor quality and unevenness of the golden ear fungus strains, many fake and invalid strains often fail to produce mushrooms after cultivation.
