First, the production of bacterial bags
(1) Formula: 1.79% poplar sawdust, 20% wheat bran, 1% gypsum, 0. 1% carbendazim (50% wettable powder); 2. Corn cob (crushed to the size of broad bean) 45%, poplar sawdust 40%, corn flour 13%, gypsum 1%, lime powder 1%, carbendazim 0. 1%(50% wettable powder). Wood chips should be aged for more than half a year, and wheat bran must be fresh, free from mildew and moth.
(2) Mixing: after weighing the above raw materials, mix sawdust, wheat bran and gypsum together, stir them evenly, turn them over for 4-5 times, then put carbendazim and lime into water, stir them evenly, and spray them into dry materials with a watering can. While watering, mix the materials evenly, and adjust the water content of the culture material to about 60% (that is, when the material is pinched by hand, the wet material will agglomerate, and water drops will appear between fingers but not drop).
(3) Bagging: low-pressure polyethylene film is used, with the size of large bag being 25 × 55cm and the size of middle bag being 17 ~ 20 × 55cm. The big bag can hold 2.0 kg of dry material, and the middle bag can hold about 1.5 kg of dry material. Before loading, seal one end of the plastic bag until it is completely sealed. Put the evenly stirred culture material into a bag with appropriate tightness. There is no softness in the middle of the hand-packed material package and there is no sag at both ends.
Second, sterilization.
(1) Construction of steamer: Choose a large iron pot with a diameter of 1.5m to build a steamer with a length× width× height of 2× 2× 2.5m and a volume of 8 ~ 10 m3. The inside and outside of each pot wall shall be polished with high-grade cement, and a curtain with a diameter of 1.7m shall be made of wood squares or iron bars, which shall be placed on the pot surface and covered with sacks to prevent the material bags from being punctured. Then make a pot cover with a diameter of 2. 1m from galvanized sheet with a thickness of 1.5mm, and build a steamer for later use.
(2) Add water to the pot: Before fire disinfection, add enough water to the pot, and the water level in the pot is about 20 cm away from the curtain. Then align the bags up and down with the holes and put them on the curtains in the steamer in batches.
(3) Ignition, heating and sterilization: Ignition is performed before the pot is filled, and the temperature in the pot reaches 100℃ for 4-6 hours, then heating is continued, and the temperature is kept at 10 hour, and then it is stuffy for one night. When the feed temperature drops to 70℃, it should be taken out of the pot, quickly moved into the cooling room, and then inoculated.
Third, vaccination.
(1) Disinfect the room: 4 days before use, put the discharging tools into the room to seal the doors and windows, so as to achieve indoor sealing without air leakage, then ignite the rooms with sulfur and fumigate the rooms.
(2) Inoculation time: When the bag temperature drops to 30℃, planting should be started, and the inoculation time should be arranged in the morning and evening.
(3) Inoculation procedure: it is advisable to have four people, do a good job of division of labor, operate, light alcohol lamps, strain, take strains, mix bags and tie strains, and seal. The finished fungus bags are stacked in a "well" shape, with 5 layers in each pile.
Fourth, fungal culture.
(1) Keep the room dark and control the room temperature at about 25℃.
(2) Inoculate 16 ~ 20 days, and stick 10 ~ 20 holes with a depth of 0.5 ~ 1.0 cm on the inoculation point with a toothpick. Use a sweater needle for the second time and chopsticks for the third time, once every 10 day, gradually increasing and deepening.
V. Color management
Generally, discoloration is carried out between spawning rooms. To make the room temperature reach 20 ~ 30℃, take off the bag, soak the bacteria tube with lime water and take it out. Always ventilate, but not for too long at a time. Generally, 30 minutes is appropriate.
6. Result period management
(a) mushroom shed construction, can use the existing greenhouse, greenhouse or greenhouse. If you build a new shed, you can choose to be in the lee of the sun. The terrain is dry, flat and without water, the environment is clean and sanitary, and the water is sufficient, so it is convenient to feed and discharge materials, such as in the courtyard, in front of the house, near the village, in orchards and in open spaces among trees. The film in the greenhouse is covered with grass curtains or umbrellas.
(2) discharging the fungus bag; Put it horizontally on the bedstead, and the bag spacing is about 4 cm. Each layer can discharge 42 ~ 44 large bags of bacteria bags. In order to make it easier for the bacteria bag to replenish water, it is best to build a soaking pool near the shed.
(3) Changing temperature to promote mushroom growth: The temperature difference between day and night in the greenhouse must be above 65438 00℃ to stimulate the formation of mushroom buds. Keep the humidity in the shed at 85%. Where conditions permit, the method of urging flowers and mushrooms can be used to produce more flower mushrooms and create better economic benefits.
Seven, harvesting
(1) Get rid of the bad and keep the good: If the young mushrooms grow too densely, they should be picked properly and kept at a relatively uniform distance.
(2) In early spring or late autumn, you can heat it with fire, so that mushrooms can come out earlier or later. When the weather is cold in winter, the fungus bags can be folded together for the winter. When the temperature rises next year, mushrooms will grow again.
The collected mushrooms can be sold fresh or dried. After harvest, let the vat rest to cultivate bacteria, accumulate nutrition, and provide sufficient nutritional conditions for the next batch of mushrooms.
