First, the temperature difference between the stimulation: In the beginning of the fruiting phase of the fruiting body of Pleurotus ostreatus, the temperature difference of 7°C~10°C can be stimulated every day, which can promote the early fruiting and fruit development. Methods: During the daytime, the cover film is kept warm, the film is exposed on the sunny day or in the morning, the temperature difference is increased by cooling, and high temperature watering is used to induce mushrooming. Second, high-temperature stimulation: first the bacteria bed (or bacteria bag) open and dry 1 to 2 days, and then continue to re-spray water, spray 2 to 3 times a day, and even spray 2 to 3 days, during this period, generally open Membrane ventilation. The moisture content of the culture layer on the surface of the bacteria bed should be suitable for holding water in the hand. Finally, the water on the surface of the material is sucked with a cotton cloth, covered with a plastic film, and it can be budded after a few days. Third, shock bacteria stimulation: When the medium covered with hyphae, the use of elastic wood bar extrusion, flapping, prompting the growth of mycelium and the rapid differentiation of fruiting bodies, generally can increase production by about 15%. Fourth, cover the pressure stimulation: the use of sterile old newspapers, sacks, fine soil and other covering on the surface of the culture material, under the pressure of stimulation, promote the rapid growth of mycelium. Fifth, light stimulation: Pleurotus ostreatus should be sown after germination in the dark conditions, until after the mycelium hair is good exposure. In the absence of light, it can be replaced by electric light, but also has a good stimulating effect. Sixth, plant ash stimulation: After each batch of bacteria harvest, take 5% of the ash soaked in clear liquid spray, can promote mycelial growth, mushrooming and prevent redness, can increase production by 20%.
