Bailing mushroom, also known as Bai Ling Pleurotus ostreatus, is a rare and highly valued edible fungus. It features a bright white fruit body, thick and tender flesh, with a crisp texture and rich flavor. Not only does it offer high nutritional value, but it also has significant medicinal and economic benefits. In recent years, its cultivation has rapidly developed in northern China, becoming an attractive option for farmers. However, many growers face challenges when using the traditional material fermentation method. Due to limited experience and poor technical skills, the yield of Bailing mushrooms in bag cultivation remains low, resulting in suboptimal economic returns and discouraging some farmers from continuing this practice.
To improve the efficiency and quality of Bailing mushroom cultivation, a more effective fermentation method using corn cobs and sawdust as base materials has been developed. The following are two recommended formulas:
1. **Formula 1**: Corn cob 80%, rice bran 12%, corn flour 4%, gypsum 1%, calcium superphosphate 1%, lime 2%.
2. **Formula 2**: Corn cob 50%, hardwood sawdust 30%, rice bran 10%, corn flour 6%, gypsum 1%, calcium superphosphate 1%, lime 2%.
In both formulas, it is recommended to add approximately 5% of a Gluco Fermenting agent to enhance the fermentation process and improve the quality of the substrate.
**Preparation and Fermentation Process**:
Start by selecting clean, mold-free corn cobs and crush them into small bean-sized pieces. Weigh the required raw materials according to the chosen formula and mix them thoroughly. Add water until the moisture content reaches around 65%. This means that when you squeeze the mixture slightly, it should feel moist but not drip. Once fully mixed, form the materials into stacks with a height of 1 to 1.2 meters, a width of 1.5 meters, and any desired length. Drill ventilation holes every 40 cm, with a diameter of about 5 cm, and ensure they reach the bottom of the pile. Cover the stack with plastic sheets or straw curtains to maintain temperature and humidity.
Once the core temperature of the pile rises to 60–70°C, it’s time to turn the materials. Repeat this process 3–4 times, each time ensuring proper aeration and mixing. When the material turns a tan color, becomes soft and flexible, and emits a pleasant aroma, it indicates that the fermentation is complete. At this point, adjust the moisture level back to 65% and proceed with bagging for mushroom cultivation. This method significantly improves the quality and consistency of the substrate, leading to better yields and higher profitability for farmers.
