The cultivation of mushrooms in bagged soil offers a more efficient and controlled approach, eliminating the need for traditional practices like bud poking and water soaking. This method creates a stable and humid environment ideal for shiitake growth, making it a promising technique with great potential for development. However, the specific methods can vary depending on local conditions and resources.
(a) In all-overlay cultivation, 1555 cm plastic bags are used for loading, sterilizing, inoculating, and germinating as required. Once the mycelium is fully matured and the surface turns light brown, the bags are ready to be placed into the ground. The beds are constructed to be 4–5 meters long, 0.8–1 meter wide, and 35–40 cm deep. The inner walls are lined with wheat straw, while the bottom is filled with water and a small amount of lime solution. The bags are then cut open, the residue removed, and the exposed part is placed vertically into the bed. Sandy loam soil is used as the covering material, with debris like grass roots and stones filtered out. The first layer is about 1.5 cm thick, and two waterings are done. On the second watering, the space between the fungus rods is filled with soil. Every 7–10 days, another thin layer (about 0.5 cm) is added. The soil must be fine and evenly spread. The beds should be sloped and covered with a shed, which can be made from straw or other natural materials. During colder months, the shade can be removed to increase temperature. If conditions are favorable after soil coverage, mushrooms will begin to appear within 15–20 days. During this period, the soil surface is lightly sprayed every 2–3 days, but avoid direct spraying on the mushroom caps. Harvest promptly once ready, and cover the fungal tubes again after harvesting to prevent exposure. Within 7–10 days, new buds will emerge. This method ensures strong moisture retention, reduces water loss, concentrates nutrients, and results in thicker, higher-quality mushrooms.
(b) For half-soil cultivation using 1733 cm tubular bags, each bag contains 0.5 kg of dry material. These are typically prepared in August or September, and the mycelium matures in about 40 days before primordia form. After that, the bags are placed in the soil. Choose a flat area with easy access to water. The beds are 1.5–2 meters wide, built with earthen walls that are higher on the north side (50 cm) and lower on the south (20 cm), with additional walls on the east and west. A straw shade is also installed. After leveling the ground, insecticides like carbendazim and lime powder are applied. The bags are then placed vertically in rows, leaving a 10 cm walkway between them. Fine garden soil with a pH of 7–8 is used, and gaps between the bags are filled. The fungal sticks are left 2 cm above the soil, then watered and covered with a film to maintain moisture. When the air temperature is between 20–25°C, the fungal sticks will change color within 10–15 days, and the humidity should stay around 95%. Watering is done every 3–4 days, and the first harvest can occur within 20–30 days. When buds appear, watering should be gentle to avoid splashing dirt onto the mushrooms. In winter, straw curtains can help keep the area warm, allowing for year-round cultivation. In April and May, when temperatures rise, the film should be removed, and ventilation and shading managed accordingly.
(c) Another method involves arranging the mushroom plants without sterilization, covering the soil, and soaking the straw. After 7–10 days, the topsoil is removed, mulched, and heavy watering is applied. A dry-wet cycle is maintained. When many buds appear, heavy watering continues, and no further watering is needed. The film should be covered immediately if it rains. Since the fungi have already absorbed enough water, creating a "wet inside, dry outside" environment helps trigger mushroom formation. Mushrooms grown this way are thick, fleshy, and have clear patterns. After harvesting, the fungal tubes are flipped, covered with soil for 7–10 days, and then watered again. Three days later, the topsoil is removed, and the process is repeated using the same method.
This cultivation method offers several advantages: the mushrooms are thick and large in volume; yields increase by 40–50% compared to traditional methods; with proper strains, the bioconversion rate can exceed 145%, and the flowering mushroom rate reaches around 60%; the fungal rods naturally turn color after being placed in the soil, reducing contamination risks; they fully absorb the moisture stored in the soil, saving water in later stages; and it is cost-effective and easy to manage, significantly improving production efficiency.
