The method comprises the following steps: S1, mixed culture of old and young tremella aurantialba; s2, adding the plant growth-promoting flora into the polyculture medium; s3, harvesting. The method has the advantages that 1, plant growth-promoting flora is added, the symbiotic efficiency is improved, a reasonable microflora combination is adopted, and harmonious growth of polyculture of old and young tremella aurantialba is promoted; 2, the yield is increased through mixed culture of old and young tremella auramtialba, and expansion and development of young tremella auramtialba are accelerated by means of a hypha network and a basic structure of the old tremella auramtialba; 3, resource utilization is optimized through polyculture of the old and the young; 4, the stability of the strain is enhanced by mixed culture of old and young strains; 5, abundant nitrogen sources and nutrient substances are provided through animal protein; 6, the strain generation efficiency is improved through animal protein; 7, providing antibiotic activity through animal protein; and 8, nutrition supplement is enhanced through animal protein.
