specific Embodiment approach 1

[0010] Embodiment 1: The black fungus strain HW16 suitable for cultivation in Northeast China in this embodiment is identified as a new species of black fungus (auricularia auricula) and is preserved in the China Microbial Culture Collection Center. The preservation address is Beichen West, Chaoyang District, Beijing Road No. 1, Yard No. 3, Institute of Microbiology, Chinese Academy of Sciences, date of preservation is November 12, 2009, and preservation number is CGMCC3430; the fruiting body of the black fungus species suitable for cultivation in Northeast China is multi-single piece conglomerate, and the ear pieces Large, rootless, good ear shape, mostly bowl-shaped, can be divided into single pieces, the color of dry ears is positive, the back of the ear piece is gray to taupe, the ventral surface is black and shiny, the color difference between the front and back is large, the edge of the ear piece is round, The veins on the back are obvious; the black fungus suitable for c...

specific Embodiment approach 2

[0021] Specific embodiment two: the cultivation method of the black fungus bacterial classification that this embodiment is suitable for cultivation in Northeast China is carried out according to the following steps:

[0022] 1. Culture medium production: Weigh 82% broad-leaved miscellaneous sawdust, 15% wheat bran or rice bran, 2% bean flour or bean cake, 0.5% gypsum and 0.5% lime by mass percentage, then mix with water, Make the water content 60% to 70% to obtain the wet material of the culture medium; the cultivated species adopts a bacteria bag with a size of 17cm×33cm, and each bag contains 1.0 to 1.1kg of the wet medium material, and seals it with cotton.

[0023] 2. Sterilization and inoculation: Cultivated species are sterilized by high-pressure damp heat (sterilization at 121°C for 2 hours), or at atmospheric pressure (sterilization at 100°C for 8 hours); each bottle of original seed is inoculated with 30-40 bacteria bags .

[0024] 3. Cultivation conditions: Bacteri...

Abstract

The invention discloses a black fungus strain suitable to be cultivated in northeast regions of China, relates to the black fungus strain and aims to solve the problems of low yield, poor quality and low resistance existing in the black fungus strain used in the conventional production. The black fungus strain suitable to be cultivated in the northeast regions of China belongs to a new black fungus variety and is preserved in China General Microbiological Culture Collection Center (CGMCC), Institute of Microbiology Chinese Academy of Sciences, Chaoyang District, Beijing with the collection number of CGMCC3430 on 12th November, 2009. A plurality of fruit bodies of the black fungus strain suitable to be cultivated in the northeast regions of China aggregate with one another and have large agarics which are rootless and generally bowl-shaped and can be split into single pieces; the back side of each agaric is grey to grey brown, and the ventral side of the agaric is black and glossy; the color difference between the front and back sides is large; and the edge of each agaric is round, and network veins on the back side are remarkable. The black fungus strain suitable to be cultivated in the northeast regions of China has dry agaric yield of 40 to 55 grams / bag, and has the advantages of stable nature, high resistance, quality superior to that of other varieties and higher commodification.

Description

technical field [0001] The invention relates to a black fungus strain. Background technique [0002] Northeast my country is the main producing area of ​​black fungus, and the total output of black fungus accounts for more than half of the country's total. The black fungus strains currently used in production have low yield (average yield 35g-40g / bag), poor quality (chrysanthemum type, large ear root, small ear piece, not easy to open), weak resistance (susceptible to Bacterial contamination, prone to rotten ears) and other problems. Contents of the invention [0003] The object of the invention is to solve the problems of low yield, poor quality and weak resistance of the black fungus strains used in the existing production, and provide a black fungus strain suitable for cultivation in the northeast region. [0004] A black fungus strain HW16 (Heiwei 16) suitable for cultivation in the Northeast region of the present invention is identified as a new species of the genus...
