Ganoderma is a famous medicinal fungus. Medical research shows that: Ganoderma lucidum fruit body and spore powder has a strong pharmacological activity, has the role of pain relief, sedation, detoxification, can be anti-tumor, regulate immunity, reduce blood sugar, has the effect of nourishing the body, longevity, won the people's Favor. The techniques for artificially high-yield cultivation of Ganoderma lucidum are now described as follows:
First, the choice of cultivation room
Choosing a reasonable Ganoderma lucidum cultivation room is an important condition for achieving high yields. According to the biological characteristics of Ganoderma lucidum, Ganoderma lucidum must be cultivated in a cultivation room capable of moisturizing, keeping warm, ventilation, proper light, smooth drainage and convenient operation. The cultivation room should be cleaned before use, and then sprayed with disinfectant twice.
Second, the formulation of cultivation materials
(1) Sawdust 75%, corn flour 16%, wheat bran 7%, gypsum and phosphate 1%; (2) sawdust 75%, wheat bran 23%, calcium carbonate 2%.
Third, the production of cultivation materials
In the preparation of culture materials, wood chips, wheat bran, gypsum powder and the like are mixed well and the water content is 60-65%. The material can be bagged after being mixed. The size of the bag is 1535 cm or 1735 cm polypropylene or polyethylene bags. 350-450 grams of dry material per bag. Polyethylene bags were sterilized at atmospheric pressure for 14 hours, polypropylene bags were autoclaved for 2 hours, and the disinfected bags were transferred to a sterile box or sterile room for aerosol fumigation. At the same time, the UV lamp was turned on for 40 minutes. Then inoculate aseptically. Generally a bottle of Wheat Seed bag 40-45 bag, a bottle of Corn Seed bag 35-40 bag. The inoculated bag is moved into a well-sterilized culture room and discharged in layers. Generally, each line discharges 6-8 layers, and there is a pedestrian line between each row.
Four, germ and mushroom management
Ganoderma lucidum is an aerobic and high-temperature fungus. The growth temperature of mycelia is best at 26-38°C. The fruit body grows best at 24-28°C, and the fruit body below 18°C ​​cannot grow normally. Therefore, the best season for the cultivation of Ganoderma lucidum in Meizhou City is 4-8 months.
1. Fermentation stage management The culture room is maintained at 22-30°C, and the relative humidity of the air is maintained at 40-60%. It is ventilated for half an hour every day to check and control the contamination of the bacteria. There is astigmatism in the room and the glare can be avoided. Generally after about 28-30 days (slow mycelial growth at low temperature) mycelium can be filled with bacteria bags.
2, out of Shiba management when maintaining the temperature of 26-30 °C, the relative humidity of air is increased to 90-95%, and provide scattered light and sufficient oxygen. Keep the ground moist (preferably a shallow layer), spray water 3-4 times around the walls and spaces every day, open the doors and ventilate the air after 8am-10am and after 4:00pm, when the temperature is low from 11pm to 2pm Ventilation. When the primordium swells to gradually form the cap, avoid direct water spray. When the cap has 2-3 laps, it sprays water from the top and bottom of the cap and sprays 3-4 times a day. Poorly ventilated, it is easy to deform the shape of Chiba and cut it off once it is deformed. The growth of the cap should have enough space.
V. Ejection powder and harvesting
When the white edge of the cap disappears and the edge becomes red, when the cap begins to lignify, the bag is wiped clean with a damp cloth, put on a shelf or placed in a carton, and can be stacked in multiple layers. The cap cannot contact each other or touch something else. Seal the bag with white paper. The spore powder injection room requires a clean and cool shade. After 30 days, white paper was opened, spore powder was collected, and the fruit body was taken. The spore body must be dried or dried. The spore powder should be sieved with a 100-mesh sieve and placed in a dry, cool place for sale.
Sixth, post-harvest management
Ganoderma Ganoderma harvested after picking, the bag into the appropriate amount of nutrient solution (or water) into a clean room, according to the previous stage of the method of cultivation management, you can harvest the second Ganoderma lucidum.
