I. Main Cultivation Sites
Cultivation sites should be located in areas with convenient transportation, reliable water and electricity supply, high and dry terrain, firm soil, proximity to water sources, and good drainage to avoid drought and flooding. The surrounding environment should be clean and hygienic, with good ventilation. There should be no livestock pens within 500m of the mushroom house and no polluting factories within 3000m. The main cultivation sites include solar greenhouses and cold frames.
(1) Solar Greenhouse: Solar greenhouses mostly adopt the "three walls and one slope" facility type. The temperature in the mushroom house is easy to control, allowing for early mushroom production in spring and continuous production in winter, making it suitable for standardized and intensive large-scale cultivation. Solar greenhouses should be oriented east-west, facing south, with a length of 40-60m, a width of 7-9m, a north wall height of 3.0-3.5m, a back slope length of 1.5m, and an angle of inclination of 30°-40°, and a wall thickness of 0.6m. The front slope uses a steel frame arch structure, with arch frames spaced 10m apart. Ventilation holes, 1 foot square, are set 1 foot above the ground on the north wall, with a spacing of 4m. A buffer room is built on the east side of the greenhouse for easy access. After the frame is built, high-strength agricultural plastic film is covered one month before cultivation. After covering the film, insulation blankets and rolling shutters are installed to facilitate the adjustment of temperature and light in the solar greenhouse. Solar greenhouses can be used for ground bed cultivation or shelf cultivation.
(2) Cold Frame: Cold frames generally have a length of 35m, a width of 6.4m, a ridge height of 2.5m, and front and rear eaves heights of 1.8m. The bottom of the frame is surrounded by plastic sheeting to create a 30cm high enclosure (which can buffer the direct impact of ventilation on the mushroom logs when the frame film is opened for ventilation). Drainage ditches are dug outside the frame. Various methods can be used for shading outside the frame: one is a double-layer shading net structure; another is a layer of plastic sheeting with a layer of shading net suspended above it, with a distance of 1m between them. If the weather is too hot, another layer of shading net can be added on top of the plastic sheeting. Each mushroom cultivation shed is equipped with two rows of micro-sprinkler pipes, with a micro-sprinkler head installed every 2 meters.
II. Production Equipment
The main production equipment includes a wood crusher, screening machine, mixing machine, bagging machine, sealing machine, sterilization pot, inoculation tent, punching machine, water injection equipment, micro-sprinkler equipment, water curtain, and drying machine.
