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 mushroom bed frame structure is set up indoors with bamboo poles or standing wood, the mushroom bed floor is fixed on the frame, the frame is generally 2 meters high, there are three layers of mushroom bed, the distance between layers is 60-65 cm; there are two kinds of mushroom bed width, the width of bilateral management is 110 cm, the width of unilateral management is 55 cm; the bottom plate of mushroom bed is made of thin wood nailed, and the distance between each strip is 1.5 cm 2.0 cm.

"Florida", which is suitable for a wide range of temperature, is selected for sowing and cultivating bacteria. The layer sowing method is used for sowing. The specific operation process is as follows: first, spread a layer of plastic film on the bottom of the mushroom bed, whose width is 2.5 times the width of the mushroom bed floor, and then spread the first layer of Pleurotus ostreatus culture material on the plastic film, about 3 cm thick; then sprinkle the first layer of bacteria on the first layer of Pleurotus ostreatus culture material, spreading a total of four layers of culture material and three layers of bacteria. After compaction, the surface of the culture material was covered with a layer of wet newspaper soaked in water, and finally the whole culture medium was tightly wrapped with plastic film.

After 60 days of inoculation, the mycelium was almost finished, and the plastic film was cut intermittently along the length of the gap at the bottom of the mushroom bed with a blade until the culture medium. The length of each slit shall not exceed 15 cm, and the horizontal and longitudinal spacing between the slits should be greater than 15 cm. In the future, every time you spray water on the mushroom bed, you should use a sprayer to spray the slit on the opposite side of the mushroom bed, and the rest of the management is the same as the routine. After the first crop of mushrooms on the reverse side of the mushroom bed is harvested, a knife can be used to cut the unscratched plastic film at the gap on the opposite side of the mushroom bed. In the whole process of cultivation, Pleurotus ostreatus on the opposite side of the mushroom bed can pick 2-3 stubble. The yield is close to that on the front of the mushroom bed.
