"It is easy to understand that animals have hearing and respond to music. What is surprising is that plants that are considered "ignorant and heartless" without hearing can actually appreciate music. Not only that, Sometimes letting them listen to music will produce wonderful effects, promoting the growth of these plants.

There is a tree that can listen to music when people play music next to it. It will sway with the rhythm of the music, and the branches and leaves on the treetop will turn 180° with the music like a Dai girl twisting her limbs in dance. When the music stops, the small tree will look like an experienced dancer. People immediately stopped dancing and became quiet. Someone made a detailed observation of this "music tree": when playing light music or lyrical songs, the little tree dances more vigorously, the music becomes more beautiful, and the dance becomes more graceful; but when When a loud march is played, or the sapling is allowed to listen to some kind of noisy or deafening sound, the "dance" of the sapling will stop immediately.

There are also different effects on the plants listening to the sound. There are few interesting reports. It is said that French scientists once conducted the following experiment: they played beautiful light music to growing tomatoes for three hours a day. The tomatoes that listened to the music grew to a weight of four kilograms and became the world's largest tomato. "King of Tomatoes". Not only tomatoes, but many other plants also seem to have musical cells. British scientists used music stimulation to cultivate cabbage weighing more than ten kilograms; the Soviets used a similar method to grow a cabbage weighing five kilograms. Radishes, sweet potatoes as big as footballs and mushrooms as big as blue balls. In 1958, someone in my country used ultrasonic music to treat wheat, corn, rice and cotton. As a result, the seed germination rate of wheat and rice were greatly improved. The growth period of the crops has been shortened, and the yield has increased. Cotton has spun out in advance, and the peach-bearing rate has increased.

These things sound amazing, but many experimental results need to be further studied using scientific methods. Verification. But from a scientific point of view, they are not fantasy, but have certain theoretical basis.

Scientific research shows that music is a rhythmic elastic mechanical wave, and its energy is in the medium. When transmitted, some chemical effects and thermal effects will also occur. When music stimulates plant cells, it will cause the nutrients in the cells to be decomposed by the sound waves, allowing them to be transported and absorbed more effectively within the plant. It helps the growth and development of plants and increases their yield. Some scientists in our country have found through research that under normal circumstances, the nutrient transport speed in apple trees is an average of several centimeters per hour; under the stimulation of harmonious piano music, the speed increases to More than one meter per hour. Scientists have also discovered that appropriate sound wave stimulation will accelerate cell division. The faster they divide, the faster they will grow.

But there is a limit to everything, as a Chinese saying goes. This is what the idiom "too much is not enough" means. The same is true for excessively strong sound waves, which are not only useless but harmful. They can cause plant cells to rupture and even die. Of course, the destructive power of noise is even greater. American scientists once conducted some kind of "controlled experiment", dividing more than 20 kinds of flowers into two groups and placing them in two different environments: noisy and quiet, for observation and comparison. The results show that the influence of noise can slow down the growth rate of flowers by about 40% on average. People have also discovered that near jet airports with noise levels above 140 decibels, crop yields are always very low, and many crops will even wither. The same principle applies.

Many people also point out that rock music has great harm to animals and plants. American scientists have conducted some experiments: under the influence of rock music, plants will wither and animals will gradually lose their appetite. It is also very harmful to people. It can not only cause hearing loss, mental depression, or induce gastrointestinal ulcers and other diseases. Some people even think that the suicide rate of young people in some areas (such as the United States) has increased and the riots are frequent, all of which are related to the influence of rock music. It is related to popularity, which will be discussed below.
