Cultivation techniques of Pleurotus ostreatus: what details should be paid attention to in harvesting?

I believe that everyone is no stranger to Pleurotus ostreatus, it is a common edible mushroom in life, because of its delicious taste, high nutritional value, simple practice, affordable price and other advantages loved by consumers. However, the cultivation and harvest of Pleurotus ostreatus is not so easy, and the yield will be affected if the growers make a mistake. Let's take a look at the cultivation techniques of Pleurotus ostreatus: what details should we pay attention to in harvesting?

What details should be paid attention to when harvesting Pleurotus ostreatus?

1. In order to keep the bacterial cap fresh, clean and not easy to crack, it is necessary to spray water before harvest to improve the air humidity. However, the amount of water sprayed should not be too large and should not be sprayed on the harvested Pleurotus ostreatus, because this will cause the mushroom body to rot.

2. As long as most of the mushrooms of the same cluster are ripe, they can be harvested together, and they do not have to wait until the mushrooms grow up. It is usually enough to harvest mushrooms twice in one tide. After the first harvest, let the culture surface dry for four to five days, spray water on the material surface again, cover the prepared film, facilitate mushroom production, and continue the management of the mushroom room. When most of the mushroom body on the mushroom bed is mature, it is necessary to clear the bed as soon as possible to ensure the management of the next batch.

3. The separate harvest of Pleurotus ostreatus uses one hand to grasp the culture material in the lower part of Pleurotus ostreatus, and the other hand to twist it. If it is a clump mushroom, in order to avoid picking up the whole culture material, instead of using the method of raw pulling and pulling, the mushroom body is cut off with a knife close to the surface of the mushroom bed.

4. Because the lid is brittle and easy to crack, it is necessary to handle it gently and minimize the number of handling. The harvested mushroom body is covered with a wet cloth on the surface and then put into a clean and smooth container to keep it moist and avoid damage to the mushroom body.

Matters needing attention in the cultivation of Pleurotus ostreatus

1. Control temperature

Pleurotus ostreatus belongs to variable temperature fruiting fungi, and variable temperature stimulation is beneficial to the formation of Pleurotus ostreatus fruiting body. After the formation of the primordium, the fruiting body entered the rapid growth stage at 15-24 ℃. When the temperature was too low, the fruiting body grew slowly, but the cap was thicker, while the temperature was too high, although the fruiting body grew fast, the cap was thin and brittle, with more fibers and poor quality.

2. Control humidity

One of the important conditions for high yield in fruiting body formation and normal development is suitable air humidity. About 65% is the best. There are different ways and amount of water spraying in different growth periods, and the initial stage of fruiting body formation is mainly spray humidification of the space, the principle of a small number of times to keep the ground moist. When most of the fruit body castor cover grows to more than three centimeters in diameter, it can spray water directly to the mushroom body, keeping the air relative humidity at about 85%. The humidity of the air is too low to form the fruiting body, and the formed one will shrink and die because of dryness. If the humidity is too high, it is easy to be contaminated by miscellaneous bacteria. After picking a tide of mushrooms, do not water for three days, and then continue to spray water, which is more conducive to the growth of a tide of mushrooms.

3. Control lighting

The stimulation of light is beneficial to the formation of the fruiting body of Pleurotus ostreatus. When the hyphae grow all over the bag, scattered light should be given appropriately, but not direct sunlight. The dark environment or weak light is not conducive to the formation of fruiting bodies, which, even if formed, will lead to a decline in yield and quality, usually with light that can read newspapers. In the absence of sunlight in the room, lights can be used to increase the light to stimulate the formation of fruiting bodies.
