“…In China, in Beijing, Shandong, Xinjiang, Shanxi, Tianjin, Jiangsu, Liaoning, and other areas, more than 30 kinds of field crops (such as strawberries, fruit trees, sweet pepper, tomato, cucumber, celery, kidney beans, edible fungi and other vegetables, as well as cotton, wheat, corn, and sunflower) have been tested with the plant acoustic frequency technology generators and have demonstrated the effect of yield increase.

Plant audio control technology is a relatively new technology with a short history of development.…”
