According to the various acoustic wave biological effect principle of sound wave agricultural engineering, designed successfully agricultural sonic generator series of products, reached the requirement of the object of the invention.
Now that the particular content brief introduction of above two aspects is as follows:
Sound wave acts on the various mechanism brief introductions that plant produces the acoustic wave biological effect:
1. molecular bioelectronics and cytology etc. studies have shown that, " the molecular biosciences device " of plant cell membrane can receive the sound wave as physical agent, and the orderly activity that produces action potential controlling plant body material, energy, information, thereby produce the acoustic wave biological effect.
Main points have:
(1) plant cell membrane is arranged in order perpendicular to membrane plane by ion channel, nonionic passage and receptor protein etc. and is formed, and characteristic of semiconductor is arranged, and is called " biological device ".The 60mv-100mv potential difference is arranged inside and outside the film, be equivalent to electric-field intensity 10
7V/m.
(2) biological device can receive electricity, change, machinery environmental stimulis such as (comprising sound wave), film potential is changed, produce the keying of " action potential " control mould upper channel, thereby the exchange (being commonly called as " cell discharges and recharges ") that the inside and outside ion of control cell membrane is master's material, energy and information influences life process and produces the acoustic wave biological effect.
The molecular bioelectronics and the cytological theoretical foundation of sound wave agricultural engineering acoustic wave biological effector mechanism that Here it is.
2. the weak interaction theory of biological effect
Studies have shown that of bioelectromagnetics, though sound wave is very weak to the stimulation of plant, it can influence the biomolecule cell two, three, quaternary structure changes, thereby produces significant biological effect.
(author Shen Zi prestige Sun Ke profit 1999.28 (7)-600-602) adopts 400Hz 100db-110db sound wave irradiation plant to a literary composition, has proved that directly sound wave has obvious control action to plant cell structures " to use the variation of paying plant walls secondary protein structure under the effect of reason leaf infrared light research strong sound wave ".
3. biophysical studies have shown that, sound wave not only has the energetics effect as physical agent to plant, and the informatics effect is arranged.
" the flow cytometry strong sound wave is to the influence of plant cell cycle " (author: Li Tao Hou Yue rosy clouds Acta Biophysica Sinica 2001-17 (1)-195-198), with 400Hz 90db-110db sound wave tobacco is tested, proved the alternate stress that sound wave produces.The directly fissional synchronization of influence has promoted synthesizing of S phase DNA ..., having promoted the division of tobacco filament cell, this is the evidence that acoustic wave biological effect energetics action principle obtains experimental verification.
4. the information function of sound wave is to importance and modulation, demodulation, time domain and the frequency domain theory principle of life entity.
Main points have:
(1) the chapter academician points out during shellfish: " the orderly in a organized way activity of these three amounts of material, energy and information is bases of life ".
(2) famous physicist Schrodinger proposes: " basic problem of life is the information problem " information is being controlled the metabolism of biological substance, energy and is being grown.The orderly in a organized way activity of organism in other words be unable to do without the coordination of information.
(3) big science man Einstein said: " track of intracellular particle movement is Brownian movement, but is different from the Brownian movement of no living world." when the descendant points out its real meaning for example: after mother slept soundly at night, very big brouhaha is noisy did not wake up her, and she wakes up with a start immediately but baby one cries.The Brownian movement that these two kinds of sound waves are all air molecule is propagated, but their time domain and frequency domain character are different.In other words, modulated the information mother in sob can recognize in demodulation, and research thinks that demodulation is exactly the startup of biological effect; Many sound waves that experimental results show that modulated is crossed, its BER is unmodulated more obvious.
5. the theoretical and information Amplification Theory principle of the metastable state of biological effect
This theory is thought: life entity is that the metastable state by bulk redundancy constitutes, and the metastable state huge system has the tree spline structure, and it is relevant to pass rank, and extraneous small stimulation can cause the effect of " pulling one hair and move the whole body ".This studies confirm that the life-information transmission not with range attenuation and in accordance with " all or none is decided rate ", is equivalent to have " 0 " or " 1 " two states of calculator, and small sound stimulates can cause energy variation very big in the plant corpus, is called " information amplification ".
6. the plant protection action principle of sound wave (" play music drive away diseases and pests of agronomic crop " world technology is translated and reported 1996-03-27-2 author Li Hangzhou)
Studies have shown that, the stomatal opening of plant " back of listening to the music " leaf back, the absorption nutritional capacity strengthens, the ATP that provides to plant cell rolls up (ATP is called " plant energy " and also is the ATP enzyme), what contain in the plant makes insect disagreeable " road fourth " and contains that the material of insect nerve has increased by two times, and insect reproduction rate is the highest reduces 33% for it; Sound wave makes the Chinese cabbage aphid controlled; Sound wave makes the insect of cotton, strawberry such as cotton bollworm controlled, and cotton wilt weakens or the like and all to be confirmed by experiment.
7. the phonon coherent oscillation theory (high-frequency resonant theory) of " sound-" ripple of acoustic wave biological effect
Have 10 inside and outside the cell membrane
7The outer just interior negative extremely strong electric field of v/m causes cell " resonator " resonance, calculates according to calculating electromagnetism, and " sound-" ripple vibration frequency is 10
10-10
12Hz, when this frequency departed from, morbid state appearred in plant, if can make the plant rehabilitation when making its resonance.
8. the low-frequency resonant theory of biological effect
Be the big resonator of a 800Km between the ground of sky ionosphere and conduction, the very low frequencies radiation of the sun and the lightning wave that takes place at any time all produce vibration in this resonator.Tellurian biology in these very low frequencies (50-100Hz) environment, makes biological acceptance to very low frequencies that objective physiology and physical basis arranged for a long time over 1 years.All in this frequency range, so the biological effect of evidence very low frequencies (comprising modulating frequency) is remarkable especially as electrocardio, brain electricity, electromechanics.Sound wave low-frequency resonant biological effect theory that Here it is.
9. sound wave produces " threshold value " and " window " effect principle of biological effect
" threshold value " is meant that sound wave must have certain " dosage ", and promptly the product of sound field intensity, gradient and time must reach certain numerical value and just can produce effect." window " refers to the scope of indexs such as frequency, amplitude, just works in particular range.
10. sound wave is to other principles of plant biological effect
The influence that sound wave transmits the plant electronics, as: redox reaction, photosynthesis all have the electronics transmission; Acoustic vibration is to the influence of plant free radical, as: photosynthesis, biology is carcinogenic, aging course is all relevant with free radical; Sound wave is to influence of plant genetic gene or the like.
