The cultivation of white fungus with wood chips is small in cost, low in cost and high in efficiency. It is a new way for farmers to increase income.
1. Material preparations include broadleaf poplar, French sycamore, plum, persimmon and other wood chips. Sawdust powder should be broken like rice bran. Avoid trees containing bactericidal substances such as aromatic oils.
2. Culture medium Tremella medium formula: dry wood chips 66.5 kg, wheat bran or rice bran 30 kg, sucrose 1 kg, gypsum 1 kg, magnesium sulfate 0.5 kg, soybean 1 kg. When preparing, first soak soybeans in water for 6 hours - 12 hours, ground into soybean milk, mix with sucrose and magnesium sulfate with water, then mix wood chips, wheat bran and gypsum and pour into the mixture. Finally, the cultured ingredients were put into a wide-mouth bottle and filled with compaction. And in the middle of the bottle, a 2 cm deep, 1.5 cm diameter inoculation hole was used. The plastic bottle and kraft paper are wrapped around the bottle and fastened with rubber bands.
3. Inoculation Place the bottle containing the culture medium in a steamer and cook it for 6 hours to sterilize it at a high temperature. After cooling, place it in the inoculation box. Put the inoculated spoons, bacterial knives, and alcohol lamps together, and disinfect the space with potassium permanganate. When inoculating, use a spoon to pick the peanut-sized tremella seed, pass the flame of the alcohol lamp, place it in the inoculation hole, and gently compact it. Wrap the plastic film and kraft paper and use a rubber band to fasten the bottle. A bottle of 500 grams - 750 grams of the original species, can be inoculated 50 bottles - 80 bottles of cultivation bottles.
4. After the cultivation of the strained culture bottles, the culture bottles must be promptly moved to a cultivation room at 20°C--28°C for cultivation. The bed frame is set up indoors, divided into 4 layers - 6 layers, spacing 40 cm. Turn every three days. After 3 days, white mycelium appeared in the inoculated hole. After 8 days - 10 days, the hyphae spread about 3 cm in the bottle. At this time, the film at the bottle mouth can be removed, and a paper tube is set at the mouth of the bottle with kraft paper, about 3 cm above the bottle mouth, and after another 5 days - 10 days, the mycelium turns from tender to thick, The indoor temperature is preferably 23°C to 25°C, and the relative air humidity is controlled at about 70%. After earing, the air relative humidity is controlled at 75%-80%. When the white fungus grows to a diameter of about 4 cm to 5 cm, the paper tube can be opened, and the cultivation bottle can be discharged on a bed frame covered with a plastic film. The relative humidity of the air should be maintained at about 95%, so that the mycelium can be differentiated and strengthened. ventilation. When the white fungus grows to 10 cm - 12 cm, it can be harvested.
5. The cutting knife was cut off at the base of the tremella, and the beige base was cut off with small scissors. Then wash the impurities with clean water, put it out in the sun or dry it at 40°C--60°C.
