The bag cultivation method in mushroom houses is a widely used technique that allows for efficient and controlled growth of mushrooms. This method involves using plastic bags filled with a specific substrate, which is then placed on shelves or beds within a dedicated growing room.
First, the cultivation site must be carefully selected. A clean, well-ventilated space is ideal, with 4 to 5 layers of bed frames installed at a height of about 30 cm from the ground. Each shelf should be spaced 50 cm apart to allow for proper air circulation. The bags are arranged vertically on these shelves, with approximately 100 bags per square meter. This setup ensures even distribution of light and moisture, promoting healthy mycelium development.
Next, the raw materials are mixed according to specific recipes. Common formulas include combinations of wood chips, cottonseed hulls, bean stalk powder, wheat bran, corn flour, and other nutrients. For example, one recipe might consist of 23% miscellaneous wood chips, 23% cottonseed husk, 28% bean stalk powder, and so on. Each formula is designed to provide the right balance of nutrients and moisture for optimal mushroom growth.
Once the mixture is prepared, it is packed into polypropylene or high-density polyethylene bags, typically measuring 17 cm in diameter and 34–38 cm in length. The wet weight of each bag is usually between 600 and 800 grams, with a moisture content of 62–68%. After sealing the bags, they are sterilized at 100°C for 12–14 hours. Once cooled below 28°C, the bags are inoculated with mushroom spawn under sterile conditions.
After inoculation, the bags are placed on the shelves and kept at around 25°C. It takes about 30–40 days for the mycelium to fully colonize the bag. At this point, the bags are moved to a different area for fruiting. The timing of opening the bags depends on temperature—ideally between 10–18°C. When opened, the film is lifted slightly above the substrate surface or cut open, allowing the mushrooms to emerge.
Throughout the growing process, temperature, humidity, and ventilation must be carefully managed. The ideal temperature range is 10–20°C, while humidity should be maintained between 85–95% during the early stages of mushroom formation. As the mushrooms grow, ventilation needs to increase gradually. Light exposure is also important, as fruiting bodies require diffused light for proper development.
Another variation of the bag method involves using soil cover after the mycelium has fully grown. In this approach, the bags are removed from their containers and placed into a prepared pit filled with nutrient-rich soil. The soil is enriched with organic matter, lime, and fertilizers to support the second flush of mushrooms. This method is especially useful in areas where outdoor cultivation is possible.
Lastly, the bagasse (sugarcane waste) cultivation method offers an eco-friendly alternative. Fresh bagasse is fermented and treated before being used as a substrate. The mixture is then packed into bags, sterilized, and inoculated. This method is particularly effective in regions where sugarcane is abundant, as it provides a low-cost and sustainable growing medium.
In conclusion, the bag cultivation method offers flexibility, efficiency, and control over the mushroom-growing environment. Whether using traditional substrates, soil covers, or bagasse, each technique can be adapted to suit local conditions and resources. With proper management, this method can produce high-quality mushrooms consistently and sustainably.
