摘　　要：为了探明声频控制技术对水稻生长发育、产量及品质的影响,该文对水稻进行了特定频率和响度(主频率500Hz,响度80dB)的声波处理。试验结果表明,声频处理的杂交籼稻天丰优5号增产5.11%,杂交粳稻甬优13号增产5.38%,产量差异均达到显著水平。与CK相比,声频处理天丰优5号和甬优13号的有效穗数分别增加8.40和5.80穗/m2,每穗实粒数增加2.46和4.46粒;声频处理后7和14d,天丰优5号茎蘖数分别多0.3和0.5株/从,甬优13号茎蘖数分别多1.1和1.0株/从;声频处理的天丰优5号孕穗期(9月8日)和灌浆期(10月6日)平均叶片叶绿素含量分别增加11.36%和10.41%,甬优13号孕穗期(9月22日)和灌浆期(10月20日)分别增加5.20%和4.91%;声频处理的稻米透明度均提高1个等级,天丰优5号和甬优13号垩白度分别降低21.31%和5.88%,胶稠度分别增加2.0和8.0mm,整精米率分别提高6.99%和2.22%,稻米质量指数分别提高6.58%和10.94%。该文为声频控制技术在水稻上大面积应用提供科学依据。To know the effects of acoustic frequency technology on rice growth, yield formation, and quality, the field experiment was carried out in the China National Rice Research Institute. The Tianfengyou 5 which belongs to the indica type hybrid rice and Yongyou 13 which belongs to the japonica type hybrid rice were taken as test cultivars. Split plot design was used with cultivars in the main plots and acoustic frequency treatment （AFT） and control （CK） in the sub-plots. The plots, each 100 m2 were repeated 4 times. The acoustic frequency generator developed by Zhejiang University of Science and Technology was used in AFT to regulate the acoustic wave. This acoustic frequency generator was a kind of autoplay and autocontrol system, it could play the classical music and mixed sound of birdsong and cricket song. The main frequency of AFT was about 50 Hz, and ranged from 300 to 6000 Hz, and the audio loudness was about 80 dB. The playing time was designed by the programmable timer. From rice transplanting stage to 5 days before harvest stage, the acoustic frequency generator broadcasted everyday and lasted 3 hours （08：30-11：30）. The results showed that the rice yield of AFT for Tianfengyou 5 and Yongyou 13 was 5.11% and 5.38% higher than that of CK, respectively. And the yield differences between AFT and CK for these two cultivars were significant. Compared with CK, the AFT increased the rice tillers of the early growth period. After 7 days （Sep. 8） and 14 days （Oct. 6）, the average tillers per hill of Tianfengyou 5 for AFT were 0.3 and 0.5 higher than that of CK, respectively, and the average tillers per hill of Yongyou 13 for AFT were 1.1 and 1.0 higher than that of CK, respectively. Compared with CK, the effective panicle number of AFT for Tianfengyou 5 and Yongyou 13 were increased 8.40 panicles/m2 （3.88%） and 5.80 panicles/m2 （3.33%）, respectively. Compared with CK, the average filled grains per panicle of AFT for Tianfengyou 5 and Yongyou 13 were increased 2.46 grains （1.45%） an
