Influence of audio frequency mixing of music and cricket voice on growth of edible mushrooms

In order to investigate audio frequency influence on the growth, yield and nutrient component of edible mushroom, the audio stimulating technology was applied to the mycelium of six kinds of edible mushroom (Agrocybe Cylindracea，high-temperature Pleurotu corucopiae, Pleurotus ap., Pleurotus eryngii, Pleurotu cornucopiae and Pleurocybella poprrigens) and the fruiting body of three edible mushrooms (Pleurotu corucopiae, Pleurotus ap. and Pleurotu corucopiae 18). The audio was generated by mixing classical music and cricket voice with a self-developed audio player equipment. The results showed that the sound increased the mycelium growth of all the six mushrooms by 10.2%～21%，accelerated their fruiting, advanced the body fruiting harvest time by 1-5 days and extended the picking period by about 3-8 days. The audio treatment also increased the yields of edible mushrooms by 15.76%, 13.38%, 13.05% and 7.95% in four tests respectively. By comparison of fruiting body nutrient component, the mass fraction of fat, protein and polysaccharide of Pleurotu corucopiae 18 increased by 5.88%, 8.74% and 2.78%，respectively; the mass fraction of protein and polysaccharide of Pleurotus ap. fruiting body increased by 2.37% and 43.27%, respectively. The results can provide a scientific basis for audio stimulating technology applied to edible mushroom production.
