Due to the low temperature in winter, the cultivation of shiitake mushrooms in bag materials often occurs without budding and low yield. In order to increase the yield, in addition to continuing to update and improve the varieties, the following points should also be made:
1, science vaccination inoculation deep hole is loaded more bacteria, help to enhance the ability of mushroom mycelium drought, reduce the outside temperature difference on the inoculation of the bottom of mushroom mushroom block stimulation. The mycelia of mushroom will germinate rapidly under the condition of constant temperature and humidity, and the survival rate is high. Therefore, deep-spotting, so that mushroom mycelium absorbed more nutrients, production will greatly improve.
2, hot water buds with hot water soaked buds method to bud, can make mushroom production 1 times. Selection of blocks: The bacteria that are to be made are transformed into dried and selected no pollution and complete bacteria. Soaking: Soaking hot water is a good way to cultivate buds in winter. When immersed, the water is usually first burned to 33 °C, then the bacteria into the pool, add 33 °C hot water soak 3 to 5 hours. If the water temperature decreases, hot water can be added to maintain the water temperature at 18°C~33°C. Remove the immersed mash and place it on the mushrooming site. Cover it with plastic film to maintain its humidity. Ventilate the air after ventilation. If the temperature is low during the mushrooming period, the bacteria can be directly sprayed with hot water at 18°C~33°C, and then covered with a plastic film to increase the temperature in the film so as to facilitate the normal growth of the mushroom. Harvesting: After soaking the fungal lumps, the cultivars must continue to insulate them after being covered by the film. Mushroom buds can quickly excavate the lumps. At this time, the ventilation should be strengthened to increase the relative humidity of the air. The first oyster mushroom can be harvested within 10 to 17 days. . After harvesting, uncover the membrane and allow the bacterium to dry completely. Soak it in hot water for 7 to 15 days for a second time. Supplementary nutrition: After harvesting the second mushroom, it should promptly add some nutrients to the bacteria.
3. The fruiting and curing of the mushroom fruiting body needs about one week to mature. The management of this period should be as follows: the room temperature should be kept at about 15°C, the relative air humidity should be kept at about 90%, and alternating wet and dry heat and cold stimulation. After harvesting a batch of mushrooms, it is necessary to remove the membrane and ventilate it for 8 to 10 hours so that the surface of the bacterium is slightly dry and the water sprays on sunny days. Ganoderma thin film during the day, so that mycelium rejuvenation, after 12:00 at night remove the film ventilation for 1 hour, so that low-temperature stimulation of mycelium, to promote the occurrence of mushroom buds, continuous 3 to 4 days can be. It is generally possible to grow 3 shiitake mushrooms at a time.
