摘　　要：[Objective] The aim was to study the effects of sound waves with different types and frequency characteristics on the growth of cowpea（Vigna unguiculata）during seedling stage.[Method] The insect-music mixed sound（MI）,cuckoo acoustic song,cricket acoustic song,single 400 Hz frequency sound wave,F5 and Fn sound waves composed of different frequencies were designed to investigate their effects on height and weight of cowpea seedling,and experimental data were statistically analyzed and multiple-compared by EXCEL.[Result] After treatment by sound waves with six different types and frequencies,the growth situations of cowpea were better than that in control.This indicated that sound waves could significantly promote height growth of plant.The treatments with good growth-promotion effect included 400 Hz frequency sound wave,cuckoo acoustic song and cricket acoustic song,followed by MI,Fn and F5.Cuckoo and cricket acoustic song treatment could promote the weight of cowpea seedling during seedling stage.[Conclusion] Sound waves with different types and frequency characteristics had significant growth-promotion effect on growth of cowpea during seedling stage,but their effects were different.[目的]研究不同类型、频率特征的声波对豇豆苗期生长的影响。[方法]以古典音乐与昆虫鸣声的混合声波(MI)、杜鹃鸣声、蟋蟀鸣声、单一频率的400Hz声波和多种频率合成的F5、Fn声波进行试验比较,对豇豆苗高、苗重进行测定,采用EXCEL进行统计分析和多重比较。[结果]经6种不同类型和频率声频处理后,豇豆苗期生长生长状况均显著优于对照组,表明声波能显著促进株高生长,对豇豆苗期助长效果较好的是400Hz、杜鹃鸣声和蟋蟀鸣声,其次是MI、Fn和F5;与对照组相比,杜鹃鸣声和蟋蟀鸣声处理组在生长期间能显著促进苗株增重。[结论]不同类型、频率特征的声波对豇豆苗期生长都有明显的助长作用,但作用效果有所差异。
