1. Smash and boil material: smash fresh and clean corncobs with the pulverizer, put into the pot and give a boiling, then ladle out, drain off and let cool.
2. Inoculation: mix 6 parts of corncobs with 4 pieces of strains of Black fungus. (all the materials should be cooled ahead of time)
3. Cultivation: choose the field where holds good ventilation and scatter light. People could firstly lay down thin film which owns certain amount of holes, next, spread corncobs that are mixed with strain on film, keep the thickness of about 10cm and seal ridge with sandy oil, then, cover a layer of thin film above the sandy soil and press the surroundings tightly with soil. Under the outdoor temperature of 5-15 degrees, fungus clumps will form after 15 to 20 days. Auricles appear in 38-41 days. Under the temperature of 15-30 degrees and the relative air humidity of 85%-95%, after 15 days, matured auricles can be picked, dried and then sold.
Matters needing attention: after settling materials, you could pay close attention to water-draining. After finding that auricles have appeared, then certain scattered light should be remained and direct sunlight should be strictly prevented. For the last layer of thin film, be careful to uncover mouth and ventilate to prevent too high temperature. What’s more, too much water-spraying should be avoided to prevent rotten spawns and low yield.
