Pleurotus ostreatus management

After the hyphae overgrow the bag for a period of time, there are a large number of yellowish-brown drops in the bag. This is a precursor to mushrooming. At this time, it can be timely transferred into the mushroom management. The key points of management at this stage are as follows:

1. Wide temperature difference, stimulate mushrooming. Pleurotus ostreatus is a variable temperature and strong, increase the temperature difference stimulation is conducive to mushrooming. Use morning and evening when the temperature is low, increase ventilation, lower the temperature, and increase the temperature difference between day and night to 5 °C ~ 10 °C to stimulate the mushroom. During the cold season, during the day, pay attention to warming and moisturizing, and increase ventilation and cooling at night; when the temperature is higher than 20°C, you can use methods of strengthening ventilation and spraying water to increase the temperature difference and stimulate mushrooming.

2. Strengthen humidity regulation. Mushrooming venues often spray water, so that the relative humidity of 85% to 95%. After the appearance of mushroom buds on the material surface, special attention should be paid to water spray, humidifying to the space and the ground, and do not spray water directly on the mushroom buds. Only when the mushroom buds differentiate into the caps and stipe of the mushrooms, can they spray less, Fine spray, ground spray water, make up the amount of water in order to facilitate the growth of fruiting bodies. After harvesting the first and second tidal mushrooms, when the moisture content of the bacteria bag C is lower than 60%, water should be given. The end surfaces of the bag can be stripped 1 to 2 centimeters to see the new material. Hole, put in water or nutrient solution, soak with water for 8 hours.

3. Strengthen ventilation and ventilation. Low temperature season 1 day, every 30 minutes, usually after noon water spray; high temperature, 1 day 2 or 3 times, each time 20 to 30 minutes, ventilation and more in the morning and evening, avoid high humidity airtight. Ventilation must be carried out slowly, so that the wind does not blow directly on the mushroom body, so as to avoid the water loss of the mushroom body, the edge curling and valgus.

4. Improve lighting. Scattered light can induce early fruiting, more mushrooms; dark is not mushroom; lack of light, fruiting less, long handle, cover a small, pale, deformed. Generally, it is advisable to keep the light intensity of “three points of light and seven shades of yin” in the mushroom shed, but it is not possible to have direct light, so as to avoid drying of the mushroom body.

5. Precautions in fruiting management. In the mushroom shed, it should be piled up according to the maturity of the hyphae, so that the mushroom is neat and consistent, which is conducive to simultaneous management. When the fungus bag enters the mushroom management, first untie the two ends and do not rush to fully open the bag mouth, so as to prevent the material surface from losing water and drying, affecting the normal fruiting.

6. Covered with mushrooms. Pouches are generally used after two tidal mushrooms. After replenishment management, they can continue to produce mushrooms. However, there are fewer mushrooms, and the mushroom body is small and irregular, and the economic efficiency is low. The use of soiled mushrooms will help increase production. The method of covering the soil is to open a groove in the mushroom shed, dig a width of 1 meter, depth of 20 to 30 centimeters, length of the gully, between the rake and the rake to leave a 50 cm wide access road. The two material surfaces of the mushroom barrels of the two tidal mushrooms are cleaned, the plastic bags are removed, and the two pieces are cut into two pieces and discharged vertically in the gutter. Then, the gaps between the bacteria tubes are filled with fertile vegetable garden soil and covered with the bacteria tubes. The surface is 0.5 to 1 cm thick. After covering the soil, flood the water in the gully once to infiltrate the fungus tube. In the condition of proper temperature, about 7 days, there will be mushroom buds appear on the bed of bacteria, according to the requirements of mushroom management, can continue to mushroom 4 to 5 tide.

7. Harvest period management. When the color of the cap is darker and shallower, there is a white grass in the recessed part, and the edge of the cap begins to roll up. When the spores have not been distributed in large quantities, it will reach 78 maturity, and it is suitable for harvesting.
