New techniques for cultivation and Management of Pleurotus ostreatus

Pleurotus ostreatus is a white variety of Pleurotus ferulae. It is a kind of edible fungus with strong adaptability, short production cycle and easy cultivation. The new management techniques are introduced as follows: 1. Pleurotus ostreatus is a medium-temperature strain in the cultivation season, the optimum temperature for mycelial growth is 24 ℃, and the optimum temperature for fruiting body growth is 15 ℃. Therefore, the cultivation season should be inoculated in early September, enter the long mushroom period in mid-October, inoculate in early February in spring and end in mid-May. 2, mushroom period management after inoculation, the temperature of bacteria is 25 ℃, the relative humidity of indoor air is about 70%, and the air is ventilated frequently. To prevent bright light. After 30 days of cultivation and management, when the primordium appeared on the material surface or beside the bag and reached physiological maturity, it was moved into the mushroom shed for mushroom production management. Remove the ring and cotton plug, open the mouth of the bag, control the temperature at 10 Murray 20 ℃, culture for about 7 days, appear primordium and differentiate into young buds. When the mushroom stalk grows to 2 cm, increase the amount of water sprayed and strengthen ventilation. The air relative humidity should be kept at 80% in the early stage and 85% in the later stage to prevent strong light. 3. The causes of irregular mushroom production and the ways to overcome it. The main reason for the irregular mushroom production is that when the bacteria are inoculated, some of the hyphae have not yet reached physiological maturity and moved into the mushroom shed for mushroom management. The way to overcome it is to keep the temperature of 25 ℃ 28 Mel during the growth period, fill the mycelium bag after about 30 days, and then culture 30 Mel for 40 days in an environment where the temperature is 22 ℃ and the air relative humidity is 70% Mel 75%. Then the mushroom was stimulated by scattered light when the air relative humidity was 80% Murray 85%. The daytime temperature was 13 ℃ and the night temperature was 8 ℃. After 10 Murray for 15 days, white mushroom buds appeared. 4. Harvest can be harvested when the fruiting body is as long as 8Murray 12cm. Stop spraying water after harvest and clean up the residue at and around the mouth of the bag. Let the hyphae breathe. A week later, spray water, constant temperature buds for about 15 days, the second tide of mushrooms.
