摘　　要：为探讨植物声频控制技术对新疆大田棉花生长发育和产量的影响,为该技术在棉花生产中的应用提供科学依据。该试验设5个点,每个点分声波处理和对照2个区。声频区通过QGWA-01型植物声频发生器定期给作物播放特定频率的声波,以测定声频及声强对棉花生产的影响。通过3a的对比试验表明,声波处理促进了棉花的营养生长,其中处理区棉花的株高、倒四叶宽(功能叶)和果枝数量分别较对照增加了1.17%、5.25%和1.14%;处理同时促进了棉花的生殖生长,其中,棉铃数和单铃重分别提高了9.22%和3.34%。声波处理使棉花3a的增产幅度在11.1%～13.5%,差异显著,平均增产12.7%,在一定范围内,声波的增产效应与距离声源的远近呈负相关。研究证明了植物声频控制技术对棉花营养生长和生殖生长均有促进作用,可作为植物声频控制技术推广应用的理论基础。Understanding the effects of acoustic frequency technology（AFT）on the growth of cotton would be helpful to cotton production in Xinjiang Uygur Autonomous Region.An experiment including two different treatments was set in order to investigate the effects of AFT on the growth of cotton.One treatment was to impose the plants with sound wave in special frequencies,the other was control.The results showed that compared to the control sites,by using AFT,the treated plant height of cotton,the width of the fourth expanded leaf from terminal one,boll-bearing branches,number of bolls and single boll weight were increased by 1.71%,5.25%,1.14%,9.22%and 3.34%,respectively.Acoustic waves could increase the treated cotton yield by 11.1%-13.5%,which showed significant difference and average yield increased by 12.7%in the past three years.The effect of treatment was negatively correspondent with the distance between plants and the source of sound.The study show that AFT can both promote vegetative and reproductive growth of cotton,and it can provide a scientific basis for the AFT effects on plant production.
