Earth cover and mushroom management: In a plastic greenhouse or in the open field, dig a hole and dig a 0.9 to 1 meter wide, 20 to 25 centimeters deep, unlimited-length trampoline. Remove all the bacteria from the fungus bag and cut it horizontally. For the second, the section is placed vertically downwards, the tube is 2 centimeters or so, and is filled with nutrient soil, filled with water, and the surface is covered with 3 to 4 cm of nutritious soil. The spray-like water is poured through, and the temperature is 12 to 24 degrees Celsius, relative humidity. For 85% ~ 90%, about 10 to 15 days from the beginning of the original base appears, about 20 days of sub-solid form, grow to 78 mature can be harvested, generally can take 3 to 4 mushrooms.
