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, and a crisp, delicious texture. Not only does it offer high nutritional value, but it also has significant medicinal and economic potential. In recent years, its cultivation has been rapidly growing in northern China. However, many farmers who are involved in the process often face challenges due to limited experience and poor technical knowledge. This leads to low yields and poor economic returns, which can discourage growers from continuing with Bailing mushroom production.
To address these issues, using corn cobs and sawdust as substrates for cultivation has become a popular approach. Below are the specific methods for fermentation:
1. **Recipes**
- Recipe 1: Corn cob 80%, rice bran 12%, corn flour 4%, gypsum 1%, calcium superphosphate 1%, lime 2%.
- Recipe 2: Corn cob 50%, hardwood sawdust 30%, rice bran 10%, corn flour 6%, gypsum 1%, calcium superphosphate 1%, lime 2%.
- In both formulas, it's recommended to add approximately 5% of Gluco Fermenting Agent to enhance the quality of the fermentation process.
2. **Preparation and Fermentation Process**
Begin by selecting clean, mold-free corn cobs and crush them into small pieces, similar in size to beans. Weigh the required materials according to the chosen formula and mix them thoroughly. Add water and stir well until the moisture content reaches about 65%. This means that when you squeeze a handful of the mixture, it should feel moist but not drip water.
Once the materials are evenly mixed, stack them into piles that are 1 to 1.2 meters high and 1.5 meters wide, with an unlimited length. Drill ventilation holes throughout the pile—each hole should be about 5 cm in diameter, spaced 40 cm apart and extending all the way to the bottom. Cover the pile with materials such as plastic sheets or straw curtains to maintain humidity and temperature.
When the internal temperature of the pile reaches 60–70°C, it’s time to turn the material over. Repeat this process 3–4 times, each time allowing the temperature to rise again to 60–70°C before turning. When the material turns a light brown color, becomes soft and flexible, and emits a distinct, pleasant aroma, it indicates that the fermentation is complete. At this point, adjust the moisture content to 65% and proceed to bag the substrate for inoculation.
