Operating rules for cultivation of Pleurotus eryngii

Pleurotus eryngii is a kind of large fleshy umbrella fungus growing in the subtropics, with thick meat, fine and strong stalk tissue, white and thick, and excellent taste. It is a kind of edible fungus that sells well in domestic and foreign markets. The cultivation techniques are introduced as follows: first, culture material formula 1, cottonseed hull 80%, wheat bran 18%, gypsum 2%, lime appropriate amount; 2, cottonseed hull 60%, sawdust 20%, wheat bran 18%, gypsum 2%, lime amount; 3, cottonseed hull 70%, rice straw 10%, wheat bran 18%, gypsum 2%, lime 4. 60% sawdust, 20% corncob, 18% wheat bran, 2% gypsum and appropriate amount of lime. Second, select a formula for making the cultivation bag, mix the material evenly according to the requirements, mix it 1.2 times with water, make the water content of the culture material reach 60%, and adjust the pH at the same time, the pH value is about 7.5. The specification of the cultivation bag is 17x30 cm, each bag contains about 1 kg of wet material, and the plastic rope tightens the mouth of the bag. Third, disinfect and sterilize the stove under atmospheric pressure, keep the water boiled for 8-10 hours, and then be stuffy for 10-12 hours, sterilizing 1000-2000 bags each time. 4. Inoculate, transfer the cooled cultivation bag to the inoculation room, disinfect with chemical and ultraviolet lamp for 30 minutes (or formaldehyde plus potassium permanganate fumigation) and inoculate under aseptic condition, 40-50 bags per bag. Fifth, mycelial growth will be transferred to the cultivation bag (sterilization and disinfection in advance), 80 bags per square meter, or wall stacking, usually 8 floors, keep the indoor temperature 20-26 degrees, check whether there is a contaminated bag after 5-6 days, to remove in time, generally 40-50 days mycelium can be full of bacterial bags. 6. The temperature of mushroom production requires 14-18 ℃, no more than 20 ℃, and the air humidity is 80-90%. Keep the air fresh in the mushroom room. Put the bag flat on the floor of the mushroom room and open the bag after the small buds of the fruiting body are formed in the bag mouth to keep the mushroom moist and do not spray water to the mushroom body. 7. After 5-6 days of fruiting body growth, the single mushroom weighs 50-100 grams, the cap is 3-5 cm, and the stalk is 5-12 cm long.
