What to do if the enoki mushrooms grow out of order

The irregular growth of Flammulina velutipes is mainly caused by improper management of the fruiting period. The following are reasonable management measures:

During the bud stage, the door and window of the mushroom room should be opened to enhance the light and ventilation, and spray water into the space to increase the relative humidity of the mushroom room to about 90% and reduce the temperature to about 10°C. At the same time, the bag opening is loosened to induce The occurrence of mushroom buds. A few days later, when cotton-like hyphae or yellow water droplets appear on the culture material surface, open the bag mouth, and after about 1 week, needle-like mushroom buds will gradually grow.

During the domestication period, when the fruit body grows to about 1 cm, the water spray should be reduced or stopped, and the humidity should be controlled at about 75%. Ventilate the temperature and adjust the temperature to about 5°C. After domestication, restore and maintain the temperature of the mushroom house at about 10°C to promote the growth of fruit bodies.

During the elongation period, measures should be taken to promote the rapid elongation of the stipe.

1. Sleeve and straighten the bag mouth. When the fruit body grows to 2 to 3 cm, the excess film at the mouth of the plastic bag should be stretched, lifted and straightened, the purpose is to prevent the cap from opening the umbrella and promote the extension of the stem.

2. Adjust temperature. Control the temperature at about 10°C.

3. Humidification. The relative humidity of the air should be maintained at 85% to 90%, and the mushroom house should be sprayed with water to keep it moisturized. The amount of sprayed water increases with the growth of the fruit body.

4. Low light induction. In the middle and upper part of the two rows of bed frames, a 15-watt bulb is installed every 3 to 5 meters to generate vertical light, which induces the fruit bodies to extend in the direction of the light source in bunches, and promote the elongation of the stem.

5. Regulate carbon dioxide concentration. By reducing the frequency and time of ventilation, the concentration of carbon dioxide in the air in the mushroom house is maintained at 0.1% to 0.15%. Through the above management measures, after about 15 days, a commercially available Flammulina velutipes product with a cap diameter of about 1 cm and a stipe length of 8 to 15 cm can be produced.
