There was once a scientist in India who often played the violin or played some symphonic records in the garden. After a long time, the flowers and trees in the garden grew very vigorously. After that, he officially started an experiment: in a rice field of about 1 mu, symphony music was played for 25 minutes every day. A month later, he found that the plant height of rice in this field was more than 3 cm, which was more lush and robust than that of rice with no music in the same area. The "bosom friend" of music is more than rice. If you play 25 minutes of music to the black algae every morning, it will be less than 1 days, and the black algae can breed "full of children and grandchildren". After "enjoying" the classical songs for 25 minutes every morning, the mimosa seems to be in a better mood, and its growth speed is significantly accelerated. After being stimulated by music, shrubs will also become flourishing. According to observation, tobacco, impatiens and calendula all have "inspiration" for music. Music can promote plant growth because of the stimulation of sound waves. As we all know, there are many stomata on the surface of plant leaves. Stoma is a "window" for gas exchange and evaporation of water between plants and the external environment. When the music is played, the melody of the music will produce rhythmic sound waves through the air, which will stimulate the stomata on the surface of plant leaves and increase the openness of stomata. With the increase of stomata, plants absorb more carbon dioxide, the raw material of photosynthesis, which makes photosynthesis more active and the synthetic organic substances increase continuously. At the same time, the respiration of plants has also been enhanced, providing more energy for the growth of plants, so that plants appear vibrant. Of course, plants also have a choice about music. Generally speaking, the sound is crisp and the vibration frequency is fast, so the stimulation effect is better. For example, some countries have adopted high-frequency ultrasonic waves (the vibration is more than 2, times per second, which is beyond the range of human hearing) to stimulate potatoes, cabbage, wheat, vegetables, apples and other trees, and all of them have achieved remarkable yield-increasing effects. However, plants are not all good at ultrasound. Practice has proved that a small amount of ultrasonic waves can stimulate cell division; Moderate dose can inhibit cell division; A large number will cause cell death.
