Auricular wall cultivation method

The culture formula of the fungus wall cultivation method is the same as other bag planting methods. Use a 17 cm 35 cm polypropylene bag. The bag was sterilized and inoculated according to the conventional method and cultured in a dark environment. The temperature was 18-28°C at room temperature, and the mycelium grew within the bag within 20-25 days. The culture was continued for 5-7 days and then moved to a shed wall.

First level the ground, spread 3 cm thick river sand, use 1-2 bricks to form the wall, spray 5% lime water in the shed. Then, the bacteria bags are piled on the wall foot in turn, and a total of 10-15 layers are piled. The wall spacing is 80-100 cm. The wall top is covered with opaque material. After the wall is piled, micro-holes are made with sterile needles at both ends of the bag, about 30 per side to increase oxygen supply. On both sides of the bacterium wall under the action of oxygen and light induction, ear buds appear in 3-5 days, and the bags are opened in time to spray water in the air and on the ground, keeping the relative humidity of the air at 85%-95%. When the length of the ear is 2 cm, due to the enhanced evaporation, the water can be poured on the ground and the relative humidity can be increased to 95% to facilitate the display of the fungus. After harvesting for 2 days, the water was sprayed and the ear buds appeared again after 7-10 days. Per 100 kg of culture material can produce dry ears 12-14 kg.
