The intensive production of raw materials is primarily focused on saving time, reducing energy use, minimizing consumption, and maximizing efficiency. Choosing the right raw materials plays a crucial role in this process. For instance, *Pleurotus ostreatus*, commonly known as oyster mushrooms, is one of the easiest edible fungi to cultivate, with simple methods and diverse techniques available. Among these, low-cost and easy-to-handle cultivation methods are preferred. There are two main types of cultivation: raw material cultivation and clinker cultivation.
Raw material cultivation involves using unsterilized substrates, typically through a composting method. After mixing the medium with water, it is piled up and covered with plastic to allow natural heating. Once the core temperature reaches 60°C, the outer edges are moved to the center, and the pile is re-stuffed to raise the temperature again. This process is repeated three times before inoculation and bagging. By carefully controlling the carbon-nitrogen ratio and maintaining high-temperature conditions, the growth of unwanted bacteria can be effectively suppressed, allowing *Pleurotus ostreatus* to grow more rapidly and efficiently.
Through experimental studies on bagging intensification, it was found that a plastic bag size of 18 cm by 45 cm (30 cm after loading) with 0.6 kg of dry material yielded the best results. In this bagging system, a two-layer, three-layer strain technique is used—meaning two layers of substrate are placed on top of each other, with a layer of mycelium sandwiched between them. This method is particularly well-suited for large-scale, intensive production.
Intensive management differs from traditional cultivation in that it uses a "positioning mushrooming" approach. Instead of opening the bags fully for oxygen exchange, small holes are reserved for controlled air flow. This prevents competition among mushroom buds during their growth phase, which can lead to shrinkage and unnecessary nutrient loss. Additionally, conventional methods often result in overly large openings, causing dead mushrooms and lower-quality yields. The positioning technique avoids these issues by not fully opening the bags, thus reducing water evaporation and improving overall management efficiency. This approach supports more consistent and higher-quality mushroom production in an intensive setting.
