Three methods of oversummer management of Pleurotus ostreatus
Spring sowing Pleurotus ostreatus and late winter sowing Pleurotus ostreatus, often harvest 1-2 stubble mushrooms, encounter high temperature can not continue to produce mushrooms. In order to make Pleurotus ostreatus safely oversummer and preserve nutrients, Pleurotus ostreatus continues to produce mushrooms in autumn, and summer management can be carried out.
The mycelium block (bag) air-drying method is simple and convenient. Air-dry the mycelium block (bag) without mushroom or only 1 or 2 stubble mushrooms (the bag without mushroom need not be opened) and place it in a cool and ventilated place. If you put it outdoors, add mulch to prevent rain, moisture and mildew. After the temperature drops in September, the mycelium (bag) is soaked in the pool to make it absorb water, and the mushroom can be produced.
The ditch storage method should select a place with high terrain and convenient drainage, dig a storage ditch with a width of 50 cm and a depth of 60 cm to 70 cm, pat the ditch wall, spread lime (to facilitate disinfection, sterilization, and prevent miscellaneous bacterial infection), and then put the mycelium (bag) into the ditch. The overlying soil on the ditch is about 50 cm thick, 15 cm above the ground and arched to facilitate drainage. After entering the autumn, the soil is taken out and let it produce mushrooms.
In the wet soil covering method, the mycelium block (bag) or material surface without mushroom or only 1 or 2 stubble is slightly air-dried and directly covered with wet soil with a thickness of 40 cm, so that the temperature change is small, the respiratory intensity is low, and the metabolism is slow. it can keep the mycelium with strong vitality. After the temperature drops in September, the covered soil is removed and the water is replenished to produce mushrooms. It can also make the mycelium block (bag) or material surface slightly air-dried, first cover the film, then cover the soil with 3 cm thick soil and pat it, and then cover the soil with grass curtain to shade the sun to prevent high temperature. When the temperature drops in autumn, it will be managed to continue to produce mushrooms.

High quality and prolific planting techniques of Pleurotus ostreatus in early spring
When the temperature in the greenhouse was lower than 8 ℃, the growth of Pleurotus ostreatus was slow, and the growth of Pleurotus ostreatus was inhibited when it was below 4 ℃. In order to ensure the normal growth and development of Pleurotus ostreatus, the temperature in the mushroom shed should be controlled at 10 ℃ ~ 20 ℃. Artificial fire or other heating measures should be taken, but the harmful substances such as carbon dioxide produced in the heating process must be discharged out of the mushroom shed. Reasonable humidification in spring when the temperature is 10 ℃ ~ 25 ℃ is suitable for the growth of Pleurotus ostreatus, increase the relative humidity of ambient air by about 85%, reduce direct sunlight and prevent the temperature from rising suddenly at the end of spring.

Causes and Control of death of Young Pleurotus ostreatus
In the production of Pleurotus ostreatus, due to the discomfort of the environmental conditions and culture materials of the mushroom room, as well as improper management or disastrous weather, the phenomenon of shrinkage, yellowing and final death often occurs on the mushroom bed; sometimes, the small mushroom on the bed dies in batches, seriously affecting the yield and economic benefits. In this regard, the author has done a lot of observation and research, summed up the causes of dead mushrooms and control methods, are introduced as follows: 1 continuous high temperature in the production of autumn mushrooms in the north, the temperature is from high to low, which is suitable for the growth and development of Pleurotus ostreatus fruit body.
