AI Technical Summary
Existing black fungus varieties suffer from slow growth, low yield, and poor stability. They are also susceptible to diseases during cultivation, making it difficult to achieve efficient and stable large-scale production.
A new strain of fungus, named Auricularia auricula Hailan No. 1, was isolated and domesticated from wild black fungus samples in Dunhua City, Jilin Province. Using a systematic breeding method, combined with specific cultivation substrate formulas and planting techniques, including primary screening, secondary screening, regional trials and production trials, growth conditions were optimized to improve yield and stability.
A black fungus variety with single-eared, multi-folded, early-maturing, and high-yielding characteristics has been developed. The length and width of the ear pieces have been significantly increased, the dry-to-wet ratio has been optimized, and it exhibits good stability and disease resistance, resulting in an 8.13% increase in yield. The growth period is concentrated in 80-92 days, and it is highly adaptable, with mycelium able to grow under different temperatures and pH values.
