The tea tree mushroom belongs to the columnar field head mushroom, which is a kind of edible and medicinal mushroom. It has a pure, fragrant and delicious taste. It grows wild on the dry trunk of the Camellia oleifera tree and is also known as the tea tree mushroom. The columnar head mushroom is rich in nutrients, has high protein content, contains a variety of essential amino acids for the human body, and is rich in B vitamins and mineral elements such as potassium, sodium, calcium, magnesium, iron, and zinc. So what are the cultivation techniques that high-yielding tea trees need to master?
1. Cultivation season
Under natural climate conditions, it is appropriate to cultivate in spring and autumn when the temperature is 20-25°C. Formula 1: 76% miscellaneous sawdust, 20% drum skin, 1% gypsum powder, 1% sucrose, 1% urea, 0.5% superphosphate, and 0.5% calcium magnesium phosphate fertilizer. Formula 2: 50% corncob, 21% boiled peel, 27% sawdust, 1% sugar, 0.5% urea, 0.5% superphosphate. Formula 3: 70% bagasse, 10% drum skin, 18% rice bran, 1% gypsum powder, 0.5% urea, 0.5% superphosphate. The water content of the three formulated culture media is all 65%, and the pH value is around 6.
2. Bag making
After the culture material is mixed, use a 17 cm x 32 cm x 0.05 cm polypropylene bag to fill it to a height of 16-20 cm. Press it properly and fold the bag mouth down to seal it. Normal pressure sterilization is maintained at 100 degrees Celsius for 10 hours and simmered for about 8 hours. After sterilization, cool to below 30°C and inoculate according to aseptic procedures.
3. Bacteria
After inoculation, move the bacterial bag into a sterilized culture room for bacterial growth. The temperature is controlled at 25 degrees Celsius, the relative air humidity is maintained at 65%, appropriate scattered light is provided, and ventilation is provided. After 30-40 days of culture, the hyphae can grow all over the bag.
4. Promote budding
After the mycelium bag is full and matures in 10 days, it can be moved to the fruiting room to promote budding. First, place the bacteria bag upright on the rack, then loosen the mouth of the bag and cover it with old newspaper. Spray water on the ground, space and newspaper to keep the relative air humidity at 85%-90% and the temperature at 15-20 degrees Celsius. Ventilate for 30 minutes in the morning and evening, and the buds will appear after about 7 days of cultivation.
5. Mushroom fruiting
After budding, the bag mouth should be opened promptly, the relative air humidity should be increased to 90%-95%, ventilation should be strengthened and appropriate scattered light should be provided to promote the growth of fruiting bodies. If the mushroom buds grow too densely and unevenly in the mushroom bush, some of the small mushroom buds should be thinned out as soon as possible. It takes about 10 days for the fruiting bodies to grow up. It is best to harvest when the cap grows to a hemispherical shape and the mushroom curtain is not broken or is about to open. When harvesting, the whole cluster should be pulled up at the base of the stipe, then packaged and sold in grades, and can be sun-dried or dried.
