The quality of edible fungus strains is directly related to the economic interests of the majority of growers, and at the same time it will also affect the credibility of breeders. Therefore, the identification of strain quality is very important. Second, the identification method of strain quality 1, direct observation. For the introduced strains, first observe with the naked eye whether the package meets the requirements, whether there is looseness of the tampon, whether the test tube, glass bottle and plastic bag are damaged, whether the tampon and the tube, bottle or bag are infected with no pests, and hyphae. The color is normal and there is no aging. Then inhale deeply on the side of the bottle and tell if it has the unique flavor of the strain. The original species and cultivated species can be taken out of the small mycelium to observe the color and evenness, and the finger is used to check whether the moisture content meets the standard. 2. Microscopic examination. If the hyphae are transparent, they are branched, there are transverse septa, and the locks are combined clearly. Coupled with the inherent characteristics of different species, they can be considered as qualified species. 3. Observe the mycelial growth rate. The strains to be tested are inserted into the slant culture medium prepared by the test tube and placed under the optimum conditions of temperature and humidity. If the mycelium grows quickly, neatly and densely, and is robust and strong, it indicates that it is a good strain, otherwise it is It is a kind of inferior bacteria. 4, fruiting test. After various assessments, it is considered that the fine strains can be expanded and then a part of the mother species can be taken out for the mushroom (ear) test to identify the actual production capacity of the strain. Two methods commonly used in fruiting experiments are bottle cultivation method and compaction method. They are cultured in the most suitable conditions of temperature and humidity. The mycelium growth rate, feeding capacity, speed of mushrooming, speed of tube transfer, fruit body morphology, and the like are observed. Yield and quality to comprehensively evaluate the pros and cons of strains.

First, the standard of quality bacteria. There are many types of edible fungi, and the standards for high-quality strains vary from variety to variety, but in general, every good strain has a common character of “pure, positive, strong, moist, fragrantâ€. The criteria are: (1) The purity of strains should be high, no bacteria can be infected, and no other similar strains can be used. (2) The strains should be pure in color, and most types of mycelium should be white and shiny, and the original species and cultivated species should be Silk should be connected into a block, no aging and discoloration; (3) Mycelium should be thick, with many branches and dense, eat quickly after inoculation into new media, and grow vigorously; (4) the medium should be moist and tightly adhere to the wall of the test tube (bottle) Without shrinking, the water content is suitable; (5) It has a unique fragrance for each species, and must not have mildew or odor.
