声音的振动頻率在15—20千赫之以上,人們耳朵感觉不到时,称为超声波。超声波对农作物的影响,是近代农业科学研究中的新途徑。据国外研究証明:少量超声波处理,能刺激细胞分裂,中量和大量的超声波能抑制細胞分裂或死亡。目前我国国內已有好些单位开始研究超声波在农业及生物学上的应用,現在把我們初步研究結果整理出来,供有关工作者的参攷。
Vibration frequency of sound in the 15-20 kHz above, people do not feel when the ear, called ultrasound. The impact of ultrasound on crops is a new approach in modern agricultural science research. According to foreign studies have shown that: a small amount of ultrasound treatment, can stimulate cell division, in the amount and a lot of ultrasound can inhibit cell division or death. At present, there are many units in our country that have started to study the application of ultrasound in agriculture and biology. Now, the preliminary results of our study are compiled out for the reference of relevant workers.
