Mushrooms have a long fruiting period, which lasted three seasons in autumn, winter and spring, about 10 months. Usually inoculated from August to September, and from November to December, mushrooms are grown. The mushrooms that were grown before December are called autumn mushrooms. Mushroom bag cultivation, autumn management is very important. The key technologies are as follows: First, indoor bacteria. It takes more than 60 days for mushrooms to mature from physiology. After inoculation, they should be promptly moved into the bacterium room for culture. The bacteria bags are discharged as "wells" and are 8-9 layers high. The room temperature is controlled at about 25°C and the relative humidity is less than 70%. After 1 to 6 days after inoculation, the hyphae are in the recovery and germination stage, and the room temperature can be controlled at 28 to 30°C. During this period, the bacteria bags cannot be turned and no ventilation is required. The sunshades cause dark light. 7 to 10 days of mycelium growth began to eat, the room temperature dropped to 26 ~ 28 °C, ventilation 2 to 3 times a day, 7 days for the first turn of the heap, the heap of good bag up and down, inside and outside the exchange position, so that each Fungal bags can be managed under the same conditions. When turning the heap, please take it gently to prevent seal damage and infection with bacteria. At the same time, carefully check the contamination of the bacteria with the turn. If you find that there are star spots, use 75% alcohol 50 ml plus 25% formaldehyde 30 ml. The mixture was injected and the affected area was closed. If germs appear in or around the inoculation block, contaminated parts should be removed and re-inoculated. If contaminated with the seal, apply the affected area with 0.2% potassium permanganate or carbendazim. After 11 to 15 days, the mycelium grew vigorously, and it had been expanded to 4 to 6 cm. The room temperature was maintained at 24°C, and the ventilation was increased to perform the second turning. One day later, bamboo was used to drill holes to increase oxygen, and four slant eyes were placed around the expanded mycelium. The bag temperature should be controlled at 20-24°C and cannot be higher than 26°C. After 50 days, the door and window shades were removed, which promoted the growth of the mycelium. Second, bacteria bags turn color. Turning color sooner or later and good or bad, it is related to the early and late fruiting and yield. After the physiology of the mycelium matures, it turns from white to reddish-brown and appears yellow water beads, followed by the primordium of mushrooms. During the color change period, indoor astigmatism should be increased and ventilation should be strengthened. When the film is opened, the cover should be opened to form a dry, wet and wet environment and promote color conversion. Third, outdoor mushrooms. Mushrooms are low-temperature warming mushrooms. When the bag turns into a reddish-brown veil, the bag is moved to the shade on the outside, covered with wheat straw mats, moistened with water, covered at night, uncovered during the day, and re-applied for 4 to 5 days. Hush mushrooms. Fourth, fruiting management. The gradual fall in autumn temperatures is conducive to robust growth of mycelium. After 3 days, the mushroom bags will be picked once a day and put into the mushroom bed frame. The bag is 7 to 10 centimeters long, until the mushrooms are all over. After the bacteria bag is placed in the bed frame, the film is cut around the mushroom bud with a sharp knife to carry the mushroom. Generally, the mushroom will not cover the film within 7 to 10 days. When the young mushroom has the size of the peanut seed, the flower can be promoted. Fifth, flowering period management. 1. humidity. Keep the relative humidity within the bag in the range of 80% to 90%, the temperature is maintained at 12 to 18°C, and there are more astigmatism and good ventilation conditions. If the humidity is too high, first perform the dehumidification, then remove the film for an hour and then cover the film, and raise a stove to drain the tide. If dry, add water to the pan and cover with a film to allow the temperature of the pan to rise to 28°C. Such as the mushroom film dripping mushroom moisture, to open the doors and windows, rose a stove for tide. 2. temperature. Due to the fact that the mushroom has a variable temperature and firm character, artificially widening the temperature difference and staggering between wet and dry can force the cap to crack and form mushroom. Therefore, cover the film during the day so that the sun through the sun, improve mushroom shed temperature of 28 °C, to open the film after 12 o'clock in the evening, so that cold air intrusion, temperature difference between day and night up to 10 °C, continuous 3 to 4 days, can be excited Mushrooms occur in large numbers. 3. Wet and dry staggered. When wet and budding, the mushroom body grows to 2 to 3 centimeters, and it can be splashed on the surface at noon on sunny days to accelerate the growth of fruiting bodies. Then, the film is opened at night to stimulate the cold air, dry the cap, and then apply the film. Cover, the use of ground temperature and wet mix, wet and dry staggered, and promote the split of the cap into the flower-shaped mushroom. China Agricultural Network Editor
