[Objective] The aim was to study the effects of different acoustic frequency of insect sound （IS） and insect-music mixed sound （MS） treatment on the growth of 6 kinds of vegetables.[Method] The insect acoustic group,insect-music mixed group and normal control group were designed to determine the related indices of 6 kinds of vegetables in unified management regularly.[Result] After different acoustic frequency treatment,besides soybean plant height,dry root weight of cabbage and greengrocery,there was significant difference of plant height,fresh weight and dry weight between the other vegetables and control.Under acoustic frequency treatment,the growth situations of six kinds of vegetables were better than control.In the growth period,acoustic frequency treatment could promote height growth （except soybean） and edible part yield.[Conclusion] Both of IS and MS could promote the plant growth,but their effects had difference.
[Objective] The aim was to study the effects of music acoustic frequency on the contents of indoleacetic acid（IAA） in 6 species of vegetables.[Method] Music acoustic frequency group and control group were designed to determine the related growth indicators of unified managed 6 species of vegetables regularly.The contents of indoleacetic acid were detected by the High Performance Liquid Chromatography（HPLC）.[Result] The music acoustic frequency had significantly increased the contents of indoleacetic acid in 6 species of vegetables,which were significantly higher than that in the control.[Conclusion] The music acoustic frequency could stimulate the IAA secretion in plants.
[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.
