Inquiries: The type of mushroom I grow is not well-groomed and it is not easy to sell on the market. What is the reason? What should I do?
Answer: This situation is mainly caused by improper management of the fruiting period. The following are reasonable management measures:
1. Bud period. Take the bud management measures to open the doors and windows of the mushroom house, enhance light and ventilation, spray water into the space, increase the relative humidity of the mushroom house air to about 90%, cool down to about 10°C, and loosen the bag mouth to induce buds. The occurrence of this, but this time must not all open the bag of plastic film in order to prevent the material moisture evaporation, affecting the formation of mushroom buds. A few days later, when the cotton-like mycelium or yellow water droplets appeared on the surface of the culture material, the bag mouth was opened, and after about 1 week, needle-shaped mushroom buds were gradually developed.
2. Taming period. When the fruiting body grows to about 1 cm, it is necessary to reduce or stop the water spray, and the humidity is controlled at about 75%. Ventilation cooling, adjust the temperature around 5 °C. After domestication, restore and maintain the temperature of the mushroom house at about 10°C to promote fruit body growth.
3. Elongation period. Take measures to promote the rapid elongation of the stipe. (1) Sleeve and straighten bag mouth. When the fruiting body grows to 2 to 3 centimeters, the extra film of the plastic bag mouth should be stretched to enhance straightening, which can limit the oxygen supply and increase the concentration of carbon dioxide. The purpose is to inhibit the opening of the mushroom cover and promote the elongation of the stipe. (2) temperature adjustment. The temperature is controlled at about 10°C. (3) Humidification. The relative humidity of the air should be maintained at 85 to 90%. Mushrooms should be sprayed with moisturizing water. The amount of water spray increases with the growth of fruiting bodies. (4) Weak light induction. Above the center 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 body to bunch up and extend in the direction of the light source to promote the elongation of the stipe. (5) regulate carbon dioxide concentration. By reducing the number of ventilation times and time, the carbon dioxide concentration in the mushroom room air is maintained at 0.1% to 0.15%. Through the above management measures, approximately 15 days later, it is possible to produce velutia mushroom products with a cap diameter of about 1 cm and a stipe length of 8 to 15 cm.
