Ultrasound refers to sound waves with frequencies above the upper limit of the human ear's hearing. Ultrasound is also widespread in nature, but it is not audible to the human ear.
Ultrasonic waves easily enter seawater, formations, the human body, and many solids and liquids, and can penetrate almost any material. Therefore, compared with light waves and electromagnetic waves, ultrasonic waves have their own unique ability to collect internal information of materials. More importantly, ultrasonic energy with a higher sound frequency or higher sound intensity can be used to change certain states of materials or have some important effects on the development and growth of organisms.
Some new applications of ultrasound in agriculture and their prospects have been reported.
When the frequency of the seed resonates with the frequency added by the ultrasound, a strong shock wave or jet is generated, which impacts the surface of the seed, changes the wall membrane structure of the cell, makes the exchange of substances inside and outside the cell, improves the activity of enzymes in the seed, and promotes the germination rate of the seed.
Ultrasound can enhance the heat transfer of food in cells and inactivate microorganisms, which can promote crop growth and increase yield.
-
Because ultrasound will promote the hormone secretion of plants, causing plants to grow.
-
Because ultrasound can mutagenesize some of the cells in the seed, mutating into something that is conducive to plant growth, ultrasound promotes plant growth.

-
Because ultrasound can speed up the secretion of plant hormones.
-
The plant may have received some kind of information.
-
Mutation becomes something that is conducive to plant growth, so ultrasound promotes plant growth.

Ultrasound can mutagenesize some of the cellular mutations in the seeds.

Different plants have different preferences for different **, such as corn and soybeans, listen to the blue rhapsody, feel good, germinate particularly fast Huluo Different plants have different preferences for different **, such as corn and soybeans, listen to the blue rhapsody, the mood sprouts comfortably, especially fast, carrot sprouts and potatoes prefer **home will's**, cabbage, peas and lettuce like Mozart**, some plants in order to show their disgust for what they don't like**, they will pay the price of death, Like roses, this elegant plant will accelerate its flowers when it hears rock 'n' roll, and withered morning glory is even more vigorous, and it will die completely after four weeks of hearing that it is going to follow.
-
You say nice things to plants every day, put good ears, plants will grow vigorously, you scold plants every day, make noise, plants will wither, because different sound waves are different, the impact on plants is not the same. Sound waves, like rain or sunlight, are important environmental factors for plant growth. ”

This: one: must be useful, this kind of thing is there.
-
Electricity can be used as fertilizer for plants, which is good for plant growth.
-
Light is also an electromagnetic wave.
Photosynthesis.

Dizzy you, to be so detailed, and so difficult, only 20, who will answer the answer you want, persuade you to raise the reward.
I don't want your points, but I just give you a piece of advice, and you need to score more points for future problems.

**And noise should have an effect on plant germination, anyway, it has an impact on the growth of plants, in fact, plants can't tell what noise is, and sound within a certain frequency is beneficial to the growth of plants.
-
There are pros and cons.
It depends on the sound.
If the sound decibel is low and soothing and regular, it is conducive to the growth of plants, but if the sound exceeds a certain decibels, it will destroy the internal tissues of the plants and hinder the growth, and the plants are as tolerant as people.
Isn't there environmental noise pollution now, that's the truth?
-
The voice of the landlord can be understood as a wave, a form of energy!
Living, cellular organisms are all affected by sound waves to a greater or lesser extent, and depending on their species, and depending on their sensitivity to sound, organisms react differently!
Therefore, sound can have an effect on plants, but whether it is beneficial or not is still being further experimented. (The practice of using sound to promote plant growth is not yet conclusive!) )
-
Of course it did.
Plants are just like people.
It's better to listen to the most appropriate standard.
It has an impact on plant growth, and plants also have emotions.
Gentle** promotes the growth of plants.
Loud noises are not conducive to the growth of plants.
-
On the 4th floor, the sound waves with certain frequencies such as ** can promote the growth of plants, and the chaotic frequency of noise and other frequencies can inhibit the growth of plants and even lead to the death of plants.
-
Yes, according to studies, some soothing ** can promote the growth of vegetables such as tomatoes, making the fruit bigger and tastier.
-
According to scientists, plants also have feelings, so it's obvious to look at them as human beings.
-
There are areas with a lot of noise, and the plant can not rest at night, causing mental disorders.
-
Sound is not helpful or bad for plants, but sound waves do.
-
According to the data, piano music can accelerate the growth of apples, and the rest can be imagined.
-
The answer is yes: there are helpful and disadvantageous.
-
Some of them are helpful and some of them are bad, and I don't know about the help and the bad, and I want to know this too, hehe.

Some! Because it's a living thing, if you have time, you can read a book called "Water Knows the Answer".
Let's take a look at the content on this web first.
You can feel the water when you say dirty words, let alone living things?
Everything has spirituality. Therefore, the accumulation of virtue, the accumulation of virtue, and the accumulation of blessings will be rewarded!

The plants are lush and dense, and the sense of hierarchy is very deep, and the tall plants and dense branches and leaves have a better isolation effect on noise, and the sound has no effect on the plants, otherwise the roadside trees in the city would have died long ago.
-
Plant walls or forests can absorb noise because their branches and leaves vibrate with the noise, which reduces the intensity of the noise and is harmless to the plants themselves.
-
Plants can't absorb noise, only the tall plants and dense foliage have a better isolation effect on noise, and the sound has no effect on the plants, otherwise the roadside trees in the city would have died long ago.
-
Substance? In fact, many things that we drive inconspicuously can absorb noise, generally speaking, those loose and porous things can absorb noise, such as sponges, cotton, and so on. Some speakers place something similar to cotton inside to absorb the echo.
-
Plants with strong noise elimination ability: coral trees, cedars, juniper, dragon cypress, metasequoia, spruce, tulipwood, oak, sea tung, osmanthus, almond, privet, etc.
-
The plants are lush and have a deep sense of layering---
It's like diffuse reflection, which breaks up noise.

Analysis of Noise Reduction Effect of Urban Plant Communities In the urban area of Shanghai, 23 representative urban plant communities were selected to determine the noise reduction effect. The results showed that the attenuation effect of plant community on noise was related to the structure and composition of the community. Coniferous forests and evergreen broad-leaved forests had the best noise reduction effect, and the noise attenuation value was greater than 10 dB. The attenuation effect of plant community on noise was significantly better than that of open land. The attenuation effect of the community with the same species, multiple layers and abundant plant species on noise was better than that of the community without vegetation in the understory. The attenuation value of noise in the community with deciduous plants as the dominant species during the growth period was 4 5 dB higher than that at the defoliation stage

Substances with low densities can absorb noise.
Aren't plants human, not animals, sleeping? Yes, plants also sleep. During the day, the leaves of the plant are all stretched out to receive the sun's rays, and at night, the leaves of the plant are gathered together, which is rest, that is, sleep. >>>More

Many people will feel comfortable and happy when they see how sunny it is, but on the contrary, they will feel depressed, irritable and sad! Presumably this has something to do with everyone's thinking, personality and way of thinking! When the weather is good, the sky is mostly bright, and vice versa, the sky is dark, and people have a lot of similar feelings about color!
