植物声频调控技术对茶叶产量和品质的影响

摘要

Tea bushes were exposed to acoustic frequency to investigate its effect on yield and quality of tea.Frequency,volume strength and duration time of the acoustic treatment were varied to find the optimal treatment played a positive role on the tea quality and yield.Among the variables,frequency appeared to be the most critical,and the cricket chirping accompanied with symphonic music was the optimal type.Taking the economic cost and market demand into consideration,a 6-hour daily of exposure to cricket chirping at a distance within 5 to 10 m from the tea bushes could increase 12.23％ on yield of tea to 24.78 g · m-2 and 11.82％ on sensory score of brewed tea to 94.6 compared to control,respectively.%利用声频调控技术处理茶树,研究声波种类、音量强弱及处理时间等因素对茶叶品质和产量的影响,确定声频调控技术在茶叶生产上的工艺参数.结果表明,植物声频调控技术对茶树产量和茶叶品质具有积极作用,声频类型因素的影响最为重要,以蟋蟀叫声为主辅配交响乐处理最优.综合经济成本、市场需求等因素,较优生产方案为蟋蟀叫声为主辅配交响乐播放时间6h,声源距离5～10 m对茶树助长效果较佳,产量达24.78g·m-2,感官指标达94.6,比对照组增产达12.23％,感官指标提高11.82％.
