Multiple Stimulation Methods for Increasing Oyster Mushroom Yield: Temperature Difference, High Temperature, Light, and Shock Treatment

Oyster mushroom

   I. Temperature difference stimulation:In the early stage of oyster mushroom fruiting body formation, giving a 7-10°C temperature difference stimulation every day can promote earlier fruiting and more uniform fruiting body development. Method: cover with film during the day to keep warm, and on sunny mornings or evenings uncover the film to expose the bed, thereby lowering the temperature and increasing the temperature difference, combined with watering at high temperature, to induce fruiting.

    II. High temperature stimulation:First leave the mushroom bed (or mushroom bags) open to dry for 1-2 days, then continuously spray heavily with water, spraying 2-3 times a day for 2-3 consecutive days; during this period, the film can generally be left open for ventilation. The water content of the culture layer on the surface of the mushroom bed is judged by water dripping out when squeezed in the hand. Blot up standing water on the substrate surface with cotton cloth, cover with plastic film to keep warm, and after a few days buds will appear.

    III. Shock stimulation:After the culture medium is fully covered with mycelium, squeeze and pat it with fairly elastic wooden sticks to increase the speed of mycelial growth and fruiting body differentiation, which can increase yield by about 15%.

    IV. Covering and pressure stimulation:Cover the culture material with sterilized old newspapers, burlap sacks, fine soil, etc.; under pressure stimulation, the mycelium grows rapidly.

    V. Light stimulation:After sowing oyster mushrooms, it is best to cultivate the mycelium in darkness, and then expose them to light after the mycelium has grown well. When light is insufficient, electric light can be used instead, and the stimulating effect is also quite good.

    VI. Plant ash stimulation:After each batch of oyster mushrooms is harvested, spray a 5% clarified soaking solution of plant ash to promote mycelial growth, make fruiting sturdy, prevent reddening, and increase yield by about 20%.
