What should be paid attention to in the cultivation of hericium Erinaceus?

Hericium erinaceus cultivation needs to pay attention to what? Please give guidance to the cultivation of Hericium erinaceus finishing the main points of cultivation, the following list for users to refer to. Note 1, reasonable selection, scientific formula cultivation Hericium erinaceus raw materials are extremely wide, such as cottonseed hull, sawdust, corncob, bean straw, weeds, distiller's grains, etc., appropriate amount of bran, corn flour and other auxiliary raw materials, with the appropriate proportion, Hericium erinaceus can grow well. If a small amount of phosphorus, potassium, magnesium and other minerals are added to these cultures, growth will be better. According to the local advantages of raw materials, the economical formula can be selected as follows: (1) sawdust 78%, rice bran or wheat bran 20%, white sugar and gypsum 1% respectively. (2) Cottonseed hull 90%, gypsum and white sugar 1% each. (3) corncob or beanstalk powder 80%, wheat bran 18% and white sugar 1% respectively. Choose one of the above formulas and mix well to make the water content reach 60%. PH is 4-6. Note: The materials selected should be fresh, mildew-free and moth-free; the mixing materials should be uniform; the loading should be rapid and enter the sterilization treatment stage in the shortest time. According to the biological characteristics of Hericium erinaceus, the optimum temperature for mycelium growth is about 25℃, and the cultivation time is 30-40 days. The optimum temperature for fruit body growth is 16-20℃. It takes about 2 months to harvest 3 crops once cultivated. Therefore, in our region, September to November production is generally appropriate. All localities can reasonably arrange production time with reference to local climatic conditions. Note 3: Choose the appropriate cultivation method 1. Hericium erinaceus bag cultivation method 15- 17cm ×26- 33cm × 0.04mm low pressure polyethylene cylinder material is selected. Put the mixed cultivation material into the bag evenly, keep the tightness appropriate, and keep it consistent from top to bottom. The bag mouth can be sleeved with a collar or tightened. After filling, immediately sterilize, atmospheric sterilization, requirements within 46 hours to quickly rise to 100℃, and maintain for about 10 hours, after a night of fire, hot bags into the inoculation room, when the bag temperature dropped to 28-30℃ can start inoculation. Inoculation should be carried out in an inoculation box or under aseptic conditions, and can be carried out by two-end inoculation or middle perforation inoculation. After inoculation, move to the culture room for cultivation. 2. Hericium erinaceus bottle cultivation method Can bottles, seed bottles, wine bottles can be used, but better with wine bottles. If you use a wine bottle, you must cut off the bottle neck by 5-7 cm, brush the bottle clean, fill it with culture material, plug it with cotton, plug it with a layer of kraft paper, and seal the can bottle with polypropylene film. Sterilization and inoculation are carried out in the same bag. Then start growing bacteria. Note 4, culture hair bacteria set culture rack, each shelf height of 30-40 cm. Indoor disinfection in advance, available 3% lysol spray, or potassium permanganate and formaldehyde fumigation. Formaldehyde 10 ml and potassium permanganate 6 g are used per cubic meter to produce steam after mixing, and the doors and windows are closed. Place the inoculated bottles or bags on a rack and maintain the room temperature at 20-26℃ and the relative humidity of the air at 70%. 25-30 Days or so hyphae can grow full, culture hyphae to shade, good ventilation, indoor darkness or weak light can be. Note 5. Management of Hericium erinaceus fruiting period 1. The opening fruiting body culture of the fungus bag must have a fruiting opening. Bottle cultivation Hericium erinaceus, pull out the cotton plug or remove kraft paper in the center of the sealing plastic film to open a diameter of 2 cm hole can be. Bag cultivation Hericium erinaceus, remove the cotton plug in the collar or remove the adhesive tape on the inoculation point, cover the bag with plastic film, tilt the film once every 2-3 days to promote the formation of mushroom buds. When the mushroom bud diameter is 2-3 cm, remove the film. 2. Temperature control and humidity adjustment of mushroom house The temperature of mushroom house should be kept between 12-20℃, and the most suitable temperature is about 18℃. The relative humidity of air should be controlled at 85-90%. Spray water 3-4 times a day with sprayer. At high temperatures, necessary cooling measures should be taken, such as top covering, ventilation, increasing water spray, etc.; at low temperatures, measures for increasing temperature and heat preservation should be strengthened. 3, the mushroom room should be properly ventilated Hericium erinaceus fruit body growth requirements have fresh air, good ventilation, fruit body a large, tight, white, fast growth, high yield, moderate length of thorns, good commodity. Otherwise, the yield will be low and even abnormal. Therefore, attention should be paid to the ventilation of the mushroom room, open the vent regularly every day, when the temperature is high, ventilate in the morning and evening, about 30 minutes each time; when the temperature is low, ventilate at noon, and keep the air fresh in the mushroom room. 4. Light of Hericium erinaceus Although Hericium erinaceus fruiting body can be formed under dark conditions, it often appears abnormal mushroom. Moreover, strong light is not conducive to the formation of fruiting bodies. Generally, 200-300 lux of light is appropriate. General mushroom room has a certain amount of scattered light can be. 6. Harvesting Hericium erinaceus should be harvested before the fruiting body is fully mature. Standard is: fruiting body size is basically long, solid, spores have not been distributed, spines 1-1.5 cm long can be harvested. Too late harvest, the meat loose, bitter heavy, unfavorable processing, and affect the formation of the next batch of mushrooms. When harvesting, press the culture medium with one hand and gently pull out the fruiting body with the other hand or cut it with a knife. After harvest, clean up the surface in time, gently scratch the bacteria, let the mycelium rejuvenate. Under suitable conditions, after 15-20 days, two tide mushrooms will appear successively. It can usually be harvested 2-3 times. It takes about 3 months from inoculation to harvest. After harvesting, the preservation should not exceed 12 hours, a small amount can be sold fresh, the amount can be dried, or it can be dried at 60℃, and then stored in double plastic bags.
