Planting techniques of Pleurotus ostreatus

White jade mushroom is a kind of rare edible fungus, which belongs to the family Agaricaceae. It is white and crystal clear, giving people a brand-new visual effect. It is more superior in taste, crisp and tender, sweet and delicious, and rich in nutrition. It has the edible functions of relieving cough and resolving phlegm, defecation and detoxification, cancer prevention and anti-cancer, and the planting value is very high. Let's take a look at the planting technology of Pleurotus ostreatus.

Formula of Pleurotus ostreatus

1. Raw material formula: ① sawdust 58%, cottonseed hull 20%, wheat bran 15%, corn flour 5%, gypsum 1%, lime 1%. ② sawdust 73%, wheat bran 20%, corn flour 5%, lime 1%, gypsum 1%.

2. Mixing standard: the raw material is poured into the mixer for dry mixing for 3 minutes and added water for 5 minutes, adding about 110 to 120 jin per 100 jin, and the amount of poultry water is 65%. After two or three times of mixing, the water content is not less than 65%.

Loading standard of Pleurotus ostreatus

1. Bottling standard: the filling height of the standard bottle is 13.5 cm, the dry material weighs about 280 grams, and the material surface is compacted and flat when filling.

2. Bagging standard: the filling height of the corner bag is 13 cm, the dry material weighs 300 to 500 grams, and the material surface is compacted and flat when loading.

Sterilization and inoculation of Pleurotus ostreatus

1, sterilization operation: after entering the steam, open the exhaust valve, make the exhaust valve in the half-open state, the temperature rises to 103: 105 ℃ to close the exhaust valve, open the discharge valve at the bottom of the sterilization cabinet, the drain valve is in the emblem open state. When the pressure gauge of the sterilization cabinet rises to 0.11 MPA and the temperature rises to 121 ℃, the clock starts and lasts for 90 minutes. After sterilization, the steam supply is stopped. The sterilization frame is cooled and cooled until the pressure drops to 0.05 MPA. The exhaust valve is opened slightly to fully drain the steam in the cabinet. When the pressure gauge is "0", the cabinet door is opened, and when the temperature drops to 80 ℃, the cabinet comes out.

2. Inoculation method: the inoculation personnel can enter the work area after air purification and ultraviolet sterilization for 40 minutes, enter the inoculation room and operate according to the operation rules of the purification room, keep the ground moist during the inoculation period, avoid rabbit dust particles floating in the air, improve the pollution rate, and use plates to detect the sterility of the inoculation purification room every 15 days. Manual inoculation takes 800 bottles (bags) per hour, and the inoculation amount of each bottle (bag) is 2025ml. The automatic vaccination machine is inoculated with 2000 bottles (bags) per hour, and the inoculation amount of each bottle (bag) is 20,25ml.

Planting Management of Pleurotus ostreatus

1. Culture management: the mycelium of Pleurotus ostreatus grows vigorously, causes bacteria quickly, and has high requirements for the environment. The temperature of the strain colonization period is controlled at 22: 24 ℃, the mycelium growth temperature is controlled at 20: 22 ℃, the air relative humidity is 60%, there is no dead corner of garbage in the room, and the miscellaneous bacteria are cleaned in time, and Suer is used for disinfection once a week.

2. Post-ripening of mycelium: the time of post-ripening of Pleurotus ostreatus mycelium depends on indoor temperature, ventilation and light. In order to accelerate the post-heating process, mushroom should be produced as soon as possible, and the indoor temperature should be controlled at 25: 28 ℃ every day, and the hyphae should be ventilated indoors.

3. Scratching standard: scratch the mycelium of Pleurotus ostreatus in time after ripening, scrape off the surface mycelium and strive for a smooth surface. The bag material cultivation is to roll up the bag mouth from top to bottom, the material surface and the bag mouth height is 3 cm, the scratched bacterial residue is poured out in time, the bag mouth is round, spray clean water on the material surface with a spray can, moisturize, and send it into the mushroom.

4. Mushroom management: the temperature of the mushroom is controlled at 12: 16 ℃, the air humidity is 90: 95%, and the light is illuminated for 6 hours a day. After 10-15 days of bud induction, the white primordium with dense millet grains differentiated on the material surface, which gradually became needle-shaped, and entered into mushroom cultivation when the acicular buds differentiated into dark brown spherical caps.

5. Timely harvest: the room temperature of Pleurotus ostreatus is controlled at 1415 ℃, and the air humidity is 85.90%. If it is too wet, it is easy to produce yellow markings. The light is 10-12 hours a day, the length of stalk is 4 cm, and the diameter of cap is 1.5-2.5 cm. The stalk length is 6-8 cm and the cap diameter is 2.6-4 cm.
