After the culture materials are properly prepared, they are bottled or packed in plastic bags, sterilized, inoculated, and cultured. After the mycelium grows over the bottle, the medium is dug out of the compact. The tools used for excavating the bacteria should be scrubbed with clean water in advance, and then cleaned and sterilized with 0.1% KMnO4 or 0.25% benzalkonium bromide solution. The bacteria and species should also be scrubbed with a disinfectant to reduce the contamination of bacteria. Before pressing the brick, you must first prepare the wooden mold, depending on the size. The commonly used specifications are 24cm in length, 17cm in width, and 6cm in height. The wood mold is composed of a rectangular piece of wood. When making bricks, pour the digging bacteria into a wooden mold covered with a thin film (disinfected with the above-mentioned liquid before use). After loading, compact the material tightly, and then wrap the thin film of the bacteria brick. Flattened and compacted with wooden boards and incubated at 20-25°C. The length of mycelial healing time depends on the temperature. High temperature, short healing time, low temperature, long healing time. It takes 3 days for temperatures above 25°C, 4 days for 20-25°C, 5 days for 15-20°C, 7 days for 10-15°C, and 10 days for 5-10°C. After the mycelium on the surface of the bacteria brick is made good. The mycelium has healed and the outsourced plastic film is removed, ie, a brick. When ear buds begin to appear, the bricks should be moved into the cultivation room. The cultivation room must also be cleaned, killed and sterilized before use. Indoor requirements for ventilation, light insulation, good hygiene and cleanliness. The appropriate growth temperature of the Auricularia fruit body is 15-27°C. If it is cultivated using natural air temperature, a suitable season must be selected. Indoor water spray should be frequent, the training room should maintain a relative humidity of 85-95%, fruit body after 15-20 days of growth and maturity, timely picking and sun storage. Outdoors, it can be cultivated in the shade or in a simple shaded shed. The river can also be dug and cultivated. As long as the environment for the growth and development of the fungus is created, the desired effect can be obtained.
