摘　　要：为了考察声波对食用菌生长、产量及营养成分等方面的影响,采用自行开发的声频设备,播放古典音乐与蟋蟀鸣声混合而成的声频,对茶树菇、高温姬菇、黑平、杏鲍菇、秀珍菇、小白菇等6种食用菌的菌丝体进行了7次声波助长试验,对姬菇、黑平和姬菇18号3种食用菌的子实体进行了4次试验。结果表明,此声频可使食用菌的菌丝体生长速度加快10.2%～21%;使子实体提早出菇,提前1～5d采菇,并可延长采菇天数;4次子实体试验的产量分别增加了15.76%、13.38%、13.05%和7.95%。经对2种子实体成分检测比较表明,姬菇18号的脂肪、蛋白质和粗多糖质量分数分别增加5.88%、8.74%和2.78%,黑平的蛋白质、粗多糖的质量分数分别提高2.37%和43.27%。研究结果为声波助长技术在食用菌生产上的推广应用提供科学依据。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.
