A good way to promote Pleurotus ostreatus
In the cultivation of Pleurotus ostreatus, some bags do not produce mushrooms after being full of bacteria, or after the first stubble is picked, the primordia of the second stubble can not be seen for a long time. In the above two cases, as long as the bacteria in the mushroom bag is normal and the temperature type of the strain is appropriate, the mushroom can be produced smoothly by taking the following measures.
First, the temperature difference stimulates the increase of the temperature of the mushroom shed during the day, ventilation and cooling at night, and artificially enlarge the temperature difference to stimulate mushroom production.
Second, after the light stimulates the bacterial bag to grow full, roll up the straw curtain in the mushroom shed every day and let the sunlight shine for a period of time (do not shine directly when the light is strong). Gutters or mushroom houses that are inconvenient for sunshine can be illuminated by light.
3. Scratching stimulation for the imbalance of carbon-nitrogen ratio caused by excessive addition of substances with high nitrogen content, such as wheat bran, rice bran or urea, mycelia grow excessively, the formation of bacterial skin is delayed, or if the bag is opened too early, and the skin of the bag is too dry to produce mushrooms, you can make a chicken claw-shaped small nail rake with iron wire, gently scratch the bacterial quilt or skin, and spray 0.5% glucose solution combined with ventilation, supplemented by temperature difference and light stimulation. It can promote budding.
Fourth, cover the soil to stimulate pressing tiles or boards or bricks on the mushroom bed or mushroom bag. The mushroom bed is covered with 1-1.5 cm thick soil, which can not only prevent miscellaneous bacteria but also moisturize and stimulate mushrooms, and the effect is better.
Fifth, hormone drugs are used to stimulate the surface of the bag or the bacterial bed with the concentration of 5ppm~10ppm naphthylacetic acid or 0.1ppm~0.5ppm triacontanol. This method can not only produce mushrooms earlier, but also increase production.

Technical Model of Field-simulated Wild and efficient cultivation of Pleurotus ostreatus
Under the premise of the same mushroom yield, the field imitation wild cultivation of Pleurotus ostreatus can reduce the investment in production facilities and labor intensity, facilitate operation and management, and produce fresh mushrooms with wild mushroom flavor and improve the commercial value of Pleurotus ostreatus. The model is practical, easy to operate, suitable for large-scale and industrial production, and has high popularizing value. Pleurotus ostreatus occupies a major position in the production of edible fungi in our province because of its advantages such as high yield, strong adaptability and large consumption. But the use of houses, greenhouses, caves and other facilities to cultivate Pleurotus ostreatus, more

New technology of producing mushroom in Pleurotus ostreatus bed
The indoor frame cultivation of Pleurotus ostreatus usually produces mushrooms only on the front of the bed, and its production capacity has not been brought into full play. If the positive and negative sides of the mushroom bed are produced at the same time, the average yield of mushrooms per square meter can be 15.5 kg per square meter without increasing the formula of culture material per unit area and the seeding amount, of which the negative side produces 7.6 kg mushrooms, which is nearly twice as much as that only in the positive side, and the mushrooms can be produced about 7 days earlier. The following introduces the main technical points of mushroom production on both sides of the Pleurotus ostreatus bed: the setting of the frame structure of the mushroom bed
