Cultivation techniques of Lentinus edodes in cold shed

First, sowing time

Xinbin area is from March 20th to April 10th, preferably before Ching Ming Festival. When the temperature in the greenhouse reaches more than 5 ℃, it can be cultivated in the canister.

2. Ingredient sterilization

Formula 1: broad-leaf sawdust 87%, wheat bran 8%, rice bran 8%, corn flour 3%, gypsum 1%, ingredient water content 58% Mui 62%.

Formula 2: 50 kg of broadleaf sawdust, 10 kg of wheat bran, 1 kg of gypsum, and 58% of water content of the ingredients 62%.

1. Mixing material: the mixed material should be sterilized in time, and the placement time should not exceed 2MUR for 3 hours to avoid the production of miscellaneous bacteria, resulting in incomplete sterilization.

two。 Steam sterilization: use the method of ejection, spread the material at the sight of air, and do it in one go until the pot is full. Before sealing the pot, put the small woven bag used for loading out of the pot into the upper layer of the pot with steaming, which plays the role of disinfection. After sealing the pot, wait for the pan to be gassed, keep it above 98 ℃ and steam for 3 hours.

3. Out of the pot cold: after the material is steamed, it should be out of the pot while it is hot. Use a small woven bag to fill the material, preferably 15kg a bag, put it in a cool place below 25 ℃, and sow seeds in a clean place.

4. Seed mixing drum: the steamed culture material is cooled to 25 ℃, then immediately mix the seed to make the barrel. It is required that the seed mixing place should be strictly disinfected, mix the pre-crushed bacteria into the cold material, and make the fungus tube immediately after mixing well.

Third, the method of making barrel

Spread the plastic film, find the right size of the mold, and then pour the culture material of the mixed bacteria into the two cylinders for 5 times, each time, press the material once, the tightness is moderate. After compaction, remove the outer iron hanging ring, gently remove the iron sheet, then wrap the plastic around the outside of the material, the bottom is in good contact with the plastic film, stick it with adhesive tape, and leave a piece of plastic at the upper end for sealing. Then, after arranging a row of eyes every 10 seconds and 15 centimeters around, gently shake the inner tube around and pull it out, and then cover the upper end of the plastic, that is, to complete the cylinder-making process. About 50 kilograms of wet material is used in each barrel (about 20 kilograms of dry material).

IV. Germ management

At the initial stage of bacteria, the temperature in the material must be raised to 20 ℃ 22 in a short time, so that the mycelium can eat immediately, occupy the site, restrain the production of miscellaneous bacteria, and cover plastic or grass curtains on the fungus tube at night. At this time, as long as there are no miscellaneous bacteria, there is enough oxygen in the material and shed for mycelium growth. The growth of mycelium will be slow and anoxic for about 20 days, at this time, the upper ground film in the middle of the tube can be opened at night, and the plastic around the shed should also be properly adjusted and ventilated; the second row of the mycelium should also be carried out at this time, so that the mycelium can continue to grow under the condition of sufficient oxygen. A long tube can see that the mycelium eats up miscellaneous bacteria and whitens, smelling a unique fragrance of Lentinus edodes mycelium.
