摘　　要：植物声频技术是一项生产有机、绿色、无公害农产品的农业高新技术。研究用声频技术对豇豆进行了小样试验,考察了声频技术对豇豆生长株高、开花期以及结豆荚数的影响。结果表明,约在500 Hz(BW-20 dB在300～6 000 Hz)主频率的声频作用下,试验组豇豆比对照组豇豆生长高度增加了21.2%,平均提前了41 h开花,结豆荚数平均增加了61%;同时,试验组在抗病性、提高复壮能力等方面较之对照组均表现出一定的生长优势。Plant sonic technology is an agricultural high-tech to produce organic and green agricultural products. Sonic technology test was carried out on three groups of cowpea （Vigna unguiculata） from July to October, 2009. The effect of audio on cowpea plant height, fluorescence and bean pod number was investigated. The results showed that with main frequency 500Hz （range 300-6 000 Hz at BW-20dB）sonic technology, the growth of cowpea increases 21.2%, early flowering 41 hours, yield increases 61%, and the test group compared with the contrastive group has advantage in strengthening resistance to disease and improving the rejuvenation ability.
