Key points of mushroom autumn management
The emergence period of Lentinus edodes is long, which goes through three seasons of autumn, winter and spring, about 10 months. Generally, it is inoculated from August to September, and mushrooms are produced from November to December. The mushrooms that grow before December are called autumn mushrooms. For bag cultivation of Lentinus edodes, autumn management is very important. The key technologies are as follows:
Indoor germs. It takes more than 60 days from inoculation to physiological maturity of Lentinus edodes. After inoculation, it should be transferred to the bacteria room for culture in time. The bacterial bag is discharged in the shape of a "well", which is 8-9 stories high, the room temperature is controlled at about 25 ℃, and the relative humidity is less than 70%. 1-6 days after inoculation, the hyphae were in the stage of recovery and germination, and the room temperature should be controlled between 28 ℃ and 30 ℃. During this period, the bacterial bag could not be turned, no ventilation and shading caused dark light. After 7-10 days, the mycelium growth began to eat, the room temperature dropped to 26 ℃ ~ 28 ℃, ventilated 2-3 times a day, and the first turn of the pile was carried out in 7 days. The top and bottom, inside and outside of the piled bags were changed, so that each bag could be managed under the same conditions. Handle gently when turning the pile, strictly prevent seal damage and infection of miscellaneous bacteria, at the same time, combined with turning the pile to carefully check the contamination of miscellaneous bacteria, if you find that there are stars of miscellaneous bacteria, with 75% alcohol 50 ml plus 25% formaldehyde 30 ml mixture injection, seal the affected area. If miscellaneous bacteria appear in or around the inoculation block, the contaminated part should be dug up and re-inoculated. If contamination is on the seal, apply 0.2% potassium permanganate or carbendazim to the affected area. After 11-15 days, the mycelium grew vigorously and expanded to 4-6 cm. The room temperature should be kept at 24 ℃, and the ventilation should be increased for the second time. One day later, bamboo was used to drill holes to increase oxygen, and 4 strabismus eyes were pierced around the expanded hyphae. The bag temperature should be controlled at 20 ℃ ~ 24 ℃, not higher than 26 ℃. After 50 days, the sunshade of doors and windows was removed to promote the mature and healthy growth of mycelium.
The bacterial bag changes color. The change of color sooner or later and whether it is good or bad is related to the emergence of mushrooms and high or low yield. After the mycelium matured, it changed from white to reddish brown, and yellow water droplets appeared, followed by the primordium of Lentinus edodes. During the color conversion period, indoor astigmatism should be increased, ventilation should be strengthened, and the film should be opened when necessary to form a dry and wet environment to promote color conversion.
Outdoor mushroom stimulation. Lentinus edodes is a kind of fruiting mushroom with low temperature and variable temperature. When the bacterial bag changes color to reddish brown bacterial film, move the bacterial bag to the outdoor shade, cover it with wheat straw mat up and down, and sprinkle water to moisturize, cover the film at night, uncover the film during the day, cover the film repeatedly for 4-5 days, cover the film to stimulate mushrooms.
Mushroom management. The temperature decreases gradually in autumn, which is beneficial to the robust growth of mycelium. After 3 days, pick the mushroom bag once a day and put it on the bed frame of the mushroom shed, the distance between the bag is 7cm and 10cm, until all the mushroom is over. After putting the bacterial bag into the bedstead, cut the film around the mushroom bud with a sharp knife to squat the mushroom. Generally squatting mushroom period 7-10 days without film, when young mushrooms have peanut seed size, can be carried out to promote flowering.
Florescence management. 1. Humidity. Keep the relative humidity in the bag at 80%-90%, the temperature at 12 ℃-18 ℃, and have more astigmatism and good ventilation. If the humidity is too high, first drain the moisture, then uncover the film for 1 hour and then cover the film, turn on a stove to drain moisture. Add water to several dry pots and cover with film to raise the temperature of the greenhouse to 28 ℃. If the greenhouse film dripping young mushroom tide, to open the doors and windows, open a stove to drain moisture. 2. Temperature. Lentinus edodes has the characteristics of variable temperature and fruiting, so artificially enlarge the temperature difference and dry-wet crisscross, which can force the cap to crack and form flower mushrooms. Therefore, cover the film in the daytime to make the sun shine through, raise the temperature of the mushroom shed to 28 ℃, and open the film after 12:00 at night to let cold air invade. The temperature difference between day and night can reach more than 10 ℃ for 3-4 days, which can stimulate a large number of mushroom buds. 3. Dry and wet staggered. When the mushroom body grows to 2cm or 3cm after budding at variable temperature, you can choose to splash water on the surface at noon on a sunny day to speed up the growth of the fruiting body, then uncover the film at night to stimulate the cold air to dry the fungus cover, and then cover the film, using the ground temperature to wet coordination, dry and wet crisscross to promote the cap to split into flower mushrooms.

Processing technology of canned Lentinus edodes sauce
Canned shiitake mushroom sauce is a new type of health food welcomed by the market. It is rich in nutrition and unique in flavor. It is a good food on the family table. Its processing technology is as follows: 1, raw materials and auxiliary materials. Lentinus edodes: choose dried Lentinus edodes with strong flavor and thick cover or fresh Lentinus edodes of good quality. Pork: choose small packages with qualification certificate to divide the meat (should be cooled to remove acid). Bean paste: selected broad bean or soybean fermented sauce, normal color, moderate viscosity, no impurities, no peculiar smell, salt content 12% Mel 15%, water content not more than 16%.

Mushroom variety: Wuxiang No.1
Characteristic: This variety belongs to high temperature mushroom variety, can produce mushroom in summer and autumn high temperature season. The temperature range of mycelium growth was 5~34℃, the optimum temperature was 24~27℃, the fruiting temperature was 5~30℃, the quality of fruit body was good under dry management. Advantages: high temperature resistance, early mushroom, quick change to moisture, good mushroom quality, high and stable yield. Disadvantages: In the environment of high temperature, high humidity and insufficient ventilation, the fungus tube is easily infected by miscellaneous bacteria, and the fruiting body occurs more, grows fast, the meat is thin, the mushroom stalk is long, and the umbrella is easy to open.
