1. Indoor bacterial growth takes more than 60 days from inoculation to physiological maturity. Therefore, after inoculation, it should be promptly moved into the hair ventilator for culture. Bacteria bags are in the form of "wells", with high levels of 8-9 layers. In general, the room temperature is controlled at about 25°C, and the relative humidity is required to be less than 70%. One to six days after inoculation, the hyphae were in the recovery and germination stage, and the room temperature could be controlled at 28-30°C. This bag can not be turned, not ventilated, shaded doors and windows caused by dark light. 7 to 10 days of mycelial 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 will be good bags up and down, inside and outside exchange positions, so that each Bacteria bags can be managed under the same conditions, and should be handled gently when turning over to prevent damage to seals and infestation with germs. The mycelium grows vigorously from 11 to 15 days, and it has been expanded to 4 to 6 cm. The room temperature is maintained at 24°C, and the ventilation is increased. The second turnover is performed. Mycelial growth extends to 7 to 10 cm in 16 to 21 days. The room temperature should be maintained at 22 to 24 °C, and pull out the bacteria stick or uncover the cloth to form a gap, so as to increase oxidation and accelerate mycelial growth. Twenty-one days later, bamboo shoots were used to increase oxygen, and four slanted eyes were formed around the expanded mycelium. Bag temperature should be controlled at 20 ~ 24 °C, can not be higher than 26 °C, after 50 days to remove the doors and windows to cover the yin to promote hyphae mature robust growth.
2. Turn the color of the bag to master the management of the color change period, because the color change sooner or later and the quality is related to the early and late mushrooming and the level of 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. Therefore, during the color change period, indoor astigmatism should be increased and ventilation should be enhanced. When the film is opened, the cover should be opened so that the dry humidity and temperature distance can be extended to form a dry, wet and wet environment and promote color conversion. The purpose is to lay aerial mycelium. Secrete pigments, forming a layer of red-brown and shiny pellicles, that is, successful color conversion.
3. Outdoor shiitake mushrooms are low-temperature warming mushrooms. When the bacteria bags turn color, the bacteria bags are moved to the shade outdoors, covered with wheat straw mats, moistened with water, covered with film at night, peeled off during the day, and repeated for 4 to 5 days. The purpose is to increase the temperature difference between day and night in the culture field, and reduce the ventilation, to promote the formation of primordia.
4. Mushroom management The autumn temperature gradually decreases from high to high, and this temperature change rule coincides with the temperature requirement of the mushroom growth and development, which is conducive to the robust growth of mycelium. Pick mushrooms three days later, pick the bags, pick them up once a day, and put them on the shelf of the shed. The distance between the bags is 7 to 10 centimeters until the mushrooms are all over. After the bacteria bag was placed in the bed frame, the film was cut with a sharp knife at the bud 4 weeks 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, the top hand is firm and can be used for flowering. If the hair is loose, continue mushrooming. Note that the bag is managed separately and continue to mushroom until it is firm.
5. Management of flowering period
5.1 Temperature management Due to the fact that the mushrooms have variable temperature and firm characteristics, artificially increasing the temperature difference and interweaving dry and wet forces the caps of the mushroom to crack and form mushroom. Therefore, cover the film during the day so that the sun through the sun, improve the mushroom shed temperature of 28 °C, to open the film after 12 o'clock in the evening 1 hour, so that cold air intrusion, temperature difference between day and night up to 10 °C above, for 3 to 4 days, It can stimulate a large number of mushroom buds.
5.2 Intermittent management in wet and dry conditions When the temperature changes and buds are raised, when the mushroom body grows to 2 to 3 cm, 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 to dry the cap. , Then cover the film, the use of ground temperature and wet mix, wet and dry staggered, and promote the split of the mushroom cap into the formation of mushrooms.
Sodium Erythorbate and Erythorbic Acid is a food additive used predominantly in meats, poultry, and soft drinks. Chemically, it is the sodium salt of erythorbic acid. When used in processed meat such as hot dogs and beef sticks, it increases the rate at which nitrite reduces to nitric oxide, thus facilitating a faster cure and retaining the pink coloring. As an antioxidant structurally related to vitamin C, it helps improve flavor stability and prevents the formation of carcinogenic nitrosamines. The use of erythorbic acid and sodium erythorbate as a food preservative has increased greatly since the U.S. Food and Drug Administration banned the use of sulfites as preservatives in foods intended to be eaten fresh (such as ingredients for fresh salads) and as food processors have responded to the fact that some people are allergic to sulfites. It can also be found in bologna, and is occasionally used in beverages, baked goods, and potato salad.

Autumn mushroom cultivation technology
Mushrooms have a longer period of mushrooming, and generally begin to mushroom from the autumn, until the end of the second year of the 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. Now we will introduce the cultivation and management techniques of mushroom bags in autumn.
