People usually use the metaphor of "playing the piano to a cow" to describe speaking without looking at the target. However, it is an indisputable fact that often playing beautiful music in cattle or chicken farms can stimulate dairy cows to produce more milk and hens to lay more eggs. It can be seen that "playing the piano to the cow" is a measure to increase production.

Cows are higher animals. They have hearing and a complete nervous system. It is understandable that cows play the piano and produce more milk. So, can music stimulate plant growth?

There was a scientist in India who often played the violin in the garden or played a few symphony records. As time went by, he discovered that the flowers and trees in the garden grew particularly vigorously. Later, he officially started an experiment: playing 25 minutes of symphony every day in a rice field of about one acre. A month later, he discovered that the average plant height of the rice in this field was more than 30 centimeters, which was more lush and stronger than the rice in the same area but without music.

The "close friend" of music is not just rice. Play music to the black algae for 25 minutes every morning. In less than 10 days, the black algae can reproduce "full of offspring". After "listening" to classical music for 25 minutes every morning, Mimosa seemed to feel more comfortable and its growth rate accelerated significantly. Shrubs will also become luxuriant when stimulated by music. It has been observed that tobacco, impatiens, marigolds, etc. all have "inspiration" for music.

Music can promote plant growth due to the stimulating effect of sound waves. We know that there are many stomata distributed on the surface of plant leaves. Stomata are the "windows" through which plants exchange gases with the outside environment and transpire water. When music is played, the melody of the music will produce rhythmic sound waves when propagated through the air. The sound wave vibration stimulates the stomata on the surface of the plant leaves, which can increase the opening of the stomata. After the stomata are enlarged, the plant absorbs more carbon dioxide, the raw material for photosynthesis, making photosynthesis more active and the organic matter synthesized continues to increase; at the same time, the plant's respiration is also enhanced, providing more energy for the growth of the plant. , so that the plants appear full of vitality.

Of course, plants also have choices about music. Generally speaking, if the sound is sharp and crisp, the vibration frequency is fast, and the stimulation effect is better. Abroad, some countries use high-frequency ultrasonic waves (vibrating more than 20,000 times per second, exceeding the range of human hearing) to stimulate potatoes, cabbage, wheat, vegetables, apples and other trees, all of which have achieved significant yield increases. Effect. However, plants do not respond well to ultrasound. Practice has proven that a small amount of ultrasound can stimulate cell division; a medium amount can inhibit cell division; a large amount can cause cell death.
