How to cultivate white fungus? A detailed explanation of the key cultivation techniques
Cultivating white fungus is not easy, it is quite complicated. In the past, the price of white fungus was very high, and even now the price of white fungus is not cheap. How to cultivate white fungus, how to grow white fungus, and the cultivation process, we will introduce one by one below to help everyone simply understand the cultivation method of white fungus. Let's look at what kind of growing conditions need to be provided.
1. Planting period
Planting white fungus is mainly done in spring and autumn, and the most suitable temperature needed is 25°C to 28°C, generally 25°C is enough for cultivation. The corresponding temperature must be reached; if the temperature is not enough, it cannot grow. Growth will not be good. Generally, white fungus can grow to maturity in about one month to one and a half months of cultivation. Among this, the mycelium growth needs about half a month to a little more than half a month. So pay attention to determining the suitable time.
2. Preparing the spawn
White fungus mycelium cannot decompose the lignocellulose in wood, and growth on sawdust culture is slow. It only grows within the range of the fruiting base, the mycelium is not tolerant of moisture, and on a condensation water slant medium it forms spores. Take material from the fruiting base for the spawn, and after taking it out place it in a silica gel desiccator; after a few months take it out and transfer it onto a slant medium. Keep it above 22°C, grow for a little more than half a month, and obtain the mycelium.
3. Culture medium
The mycelium must be inoculated into the culture medium to continue growing, so now we must continue to make the culture medium material. Use cottonseed hulls, wheat bran, and add gypsum. It is best to use cottonseed hulls from the current year, with none spoiled. Wheat bran also must not use old stock. Add water to all the ingredients and stir them together: 83% cottonseed hulls, 15% wheat bran, 2% gypsum. Then put it into special bags, and after tying them well, steam and sterilize. After sterilization and cooling, bring it to a sterile room for inoculation.
4. Fruiting management
For more than a week, spray water three times a day, keep warm at 22°C, and keep the environmental humidity at 80%. Ventilate three times, ten minutes each time, in a weak-light environment. After half a month, when the mycelium has fully grown, untie one end of the binding, spray more water, keep the temperature unchanged, increase the humidity to 85%, ventilate four times, 20 minutes each time, and drain off the yellow water. After about 20 days, when primordia appear, cut the film, keep the humidity at 90%, and ventilate for half an hour each time. After 25 days, when the fruiting bodies emerge, remove the cloth, keep it moist, and ventilate for about one hour. At more than one month, do not spray water, lower the humidity to 80%, and ventilate for half an hour. Harvest on sunny days.
The cultivation method of white fungus is somewhat different from other edible fungi, so special attention is needed. For spawn production, pay attention to disinfection when preparing the culture medium to prevent contaminating bacteria. Management after inoculation is mainly humidity, temperature, and ventilation management.
