Multiple stimulation methods for increasing yield of Pleurotus ostreatus by temperature difference and High temperature Light

Oyster mushroom

1. Temperature difference stimulation: in the early stage of the formation of Pleurotus ostreatus fruiting body, the temperature difference stimulation of 7-10 ℃ per day can promote the emergence of mushroom earlier and the development of fruiting body neatly. Methods: cover the film to keep warm in the daytime, uncover the film and open the bed in the morning or evening on a sunny day, and induce mushrooms by cooling, increasing the temperature difference, and watering at high temperature.

Second, high temperature stimulation: first leave the bacterial bed (or bacterial bag) open and dry for 1-2 days, and then spray water again continuously, 2-3 times a day, for 2-3 days. During this period, the open film can be ventilated. The water content of the culture layer on the surface of the bacterial bed shall prevail with the drop of water held by hand. The stagnant water on the material surface is dried with cotton cloth and covered with plastic film to keep warm, and buds can appear after a few days.

Third, shock bacteria stimulation: when the culture medium is full of mycelium, squeeze and beat with strong elastic wood strips to improve the speed of mycelium growth and fruiting body differentiation, which can increase the yield by about 15%.

Fourth, covering pressurized stimulation: the culture material is covered with sterilized old newspapers, sacks and fine soil, and the mycelium grows rapidly under pressure stimulation.

Fifth, light stimulation: after sowing Pleurotus ostreatus, it is appropriate to send bacteria in the dark and wait for the hyphae to be exposed. When there is a lack of light, electric lighting can be used instead, and the stimulating effect is also good.

Sixth, plant ash stimulation: after each batch of Pleurotus ostreatus is harvested, 5% plant ash soaking clarification solution is sprayed to promote mycelial growth, produce strong mushrooms, prevent redness, and increase production by about 20%.
