How to accelerate mushroom in Pleurotus ostreatus

Pleurotus ostreatus (scientific name: Pleurotus ostreatus;, also known as Pleurotus ostreatus, black peony mushroom, Taiwan also known as Pleurotus ostreatus) is a species of Pleurotus ostreatus under basidiomycetes, and it is a very common gray edible mushroom. It has the effect of chasing wind and dispelling cold, relaxing muscles and activating collaterals. Pleurotus ostreatus is rich in nutrients, containing 23 grams of protein per 100 grams, and a full range of amino acids and minerals.

Morphological characteristics of Pleurotus ostreatus

Pleurotus ostreatus belongs to tetrapolar heterogenous combination of edible fungi. The life history of Pleurotus ostreatus is similar to that of many higher basidiomycetes, and basidiospores are produced by fruiting body maturation. Basidiospores eject from the folds of mature fruiting bodies, grow germ tubes in a suitable environment, initially multinucleate, and quickly form a septum, one nucleus per cell. [2] the bud tube of Pleurotus ostreatus continuously branched and elongated to form uninucleate hyphae. The binucleate hyphae of Pleurotus ostreatus were formed after the combination of uninucleate hyphae of different sexes. Binucleate hyphae have lock-like union on the septum. With the help of lock-like union, binuclear hyphae continue to divide cells, produce branches, and grow and reproduce infinitely under suitable conditions. Binucleate hyphae reach physiological maturity after a period of growth and development, and meet suitable conditions such as temperature, humidity, light and ventilation to form a granular bud such as mulberry, which is called "mulberry stage". A few days later, the stalk grows into a short uneven stalk, shaped like a cap, called the "coral stage". After that, the stalk continues to elongate and thicken, forming a cap at the top and growing into a fruiting body. In the seed solid layer, the basidium is produced at the top of the binuclear hyphae, and its genetic material is recombined and separated to form four basidiospores. After the spores mature, they eject from the bacterial folds and complete a life cycle.

How does Pleurotus ostreatus promote mushroom?

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, temperature difference stimulation: raise the temperature of the mushroom shed during the day, cool down by ventilation at night, and artificially enlarge the temperature difference can stimulate mushroom production. Second, light stimulation: after the bacterial bag is 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 to sunshine can be illuminated by electric lights. Third, scratching bacteria stimulation: for too much added substances with high nitrogen content such as wheat bran, rice bran or urea in the culture material, resulting in carbon and nitrogen imbalance, mycelium apprenticeship, bacterial skin formation and delayed emergence of mushrooms, or because the bag is opened too early, the bag skin is too dry to produce mushrooms, it can be made of iron wire to make a chicken claw-shaped small nail rake, gently scratch the bacteria or skin, combined with ventilation spray 0.5% glucose solution supplemented by temperature difference, light stimulation, can promote bud appearance. Fourth, shock bud stimulation: with sterilized wood, branches or palms, gently persuade to pat the surface of the mushroom bed or bacterial bag, so that the mycelium is stimulated by vibration to promote its formation of primordia. Fifth, air stimulation: close the doors and windows or cover the film, increase the concentration of carbon dioxide, and then ventilate twice a day for half an hour. Sixth, soil cover pressure stimulation: press tiles or boards or bricks on the mushroom bed or mushroom bag. Mushroom bed cultivation covered with 1-1.5 cm thick soil particles, both anti-miscellaneous bacteria and moisturizing mushroom effect is better. Hormone drug stimulation: spray the surface or bed of triacontanol with a concentration of 5 parts per million to 10 parts per million naphthylacetic acid or 0.1 parts per million to 0.5 parts per million. This method can not only produce mushrooms earlier, but also increase production.
