Excellent straw mushroom strains are planted in forage culture medium (10 to 15°C). After winter. Early cultivation has proved to be a high quality producer. The mother seed (first-class seed) was obtained again by tissue separation, and the cultivation was continued and the production was used for the same year. Mushroom farmers should pay attention to the following points when purchasing grass mushroom strains: 1. The mycelium of straw mushroom is transparent, silver-gray, distributed evenly, mycelium is sparse, and red-brown chlamydospores are normal bacteria. Mushroom mother species, original species, cultivars. For example, there are more clams and spores. In general, the fruiting bodies are smaller after fruiting, whereas the fruiting bodies are larger. 2. If silver-grey grey grass mushroom mycelium is doped with white thread-like hyphae, then fish ovule-like particles will appear yellowish-brown for a long time, it may be mixed with micro-sclerotia; if the mycelium in the bottle is too dense and white It may also be mixed with bacteria and should be eliminated. 3. If the mycelium in the bacteria bottle gradually disappears and there is a plaque, it indicates that the tapeworm is infected and should be eliminated. 4. The mycelium in the bottle has shrunk and a watery liquid appears. 5. The age of the cultivar of straw mushroom is about 18 days, and it is better not to use it for more than 30 days.
