Description
The invention belongs to the biophysics technical field, relate to a kind of optical physical methoe of coordinate plant growth.
Growth and development of plant be unable to do without illumination, moisture, nutrition (fertilizer), air and temperature, particularly higher plant leaves above-mentioned five big conditions and just can't survive, at present these several condition forefathers that influence plant growing have been carried out a large amount of research and obtained very big achievement, thereby people have had way to provide nutrient of necessity and moisture to promote the growth of crop by giving the specific fertilizer of crop applying and watering, can carry out the cultivation of anti-season by the temp. and humidity that the greenhouse is regulated and control crop and needed, the regulation and control aspect of light, since finding phytochrome the end of the fifties in last century, the research of plant aspect continuous spectrum prolonged exposure morphologic species planting technology, many in the world countries are all doing, many successful reports have also been arranged particularly since the nineties in last century, the light regulation and control have become plant physiology and molecular biological hot issue in the world to the gene expression and the optical information conduction studies of plant effect, since the seventies in last century, China payes attention to visible spectrum medium-high frequency light gradually to plant growing, metabolism, grow and hereditary influence, the eighties northern China once large tracts of land promote add lustre to fertilizer and the monochrome thin film technique of adding lustre to, at wheat, cotton, corn, plant planting field such as beet and soybean is attended by the most momentous results, volume increase, the remarkable benefit of premature labor aspect.Send monochromatic spectrum prolonged exposure plant with light emitting diode in recent years, the problem of research plant growing has report also the time, but also do not find a kind of intermittent scanning characteristic that can simulating nature light to make the method for crop normal growth under manual simulation's condition, therefore aspect light, can't carry out artificial regulation and control in the present agricultural production as aspects such as moisture, nutrition, still can only rely on the nature sunshine, and sunshine different changeable along with weather, season, region, therefore the problem of living at the mercy of the elements still can't solve.Present artificial culture case great majority only use several from vehement lamp as analog light source, can only be used to cultivate rudimentary plant, the artificial culture device that really can be used to cultivate higher plant does not appear in the newspapers so far.
The method that the purpose of this invention is to provide the regulation and control of a kind of optical physics, make plant can be under manual simulation's optical physics environmental condition normal growth.
The objective of the invention is to realize: adopt the computer programmable serial vein to control the light signal that red, green, the basket radiant group that are installed in channel-type (the flat or rotary) luminous plaque produce scanning cycle pulse towards the signal that sweep generator produces scanning cycle pulse by following scheme, thereby simulate sweep signal that natural daylight produced because of moving of atmosphere steam, the concealed wire between each spectrum line and round the clock optical physics change the light pulse signal that is produced, make plant can be under manual simulation's optical physics environmental condition normal growth;
1, theoretical foundation of the present invention: A). sunshine is an absorption spectrum, between each spectral line, there is concealed wire, we find that sunshine shines on the earth through behind the atmosphere through long-term careful observation, because the influence that the water vapour in the atmosphere moves, produced periodic spectral scan characteristic, therefore shine sunshine on the plant and formed pulse, the spectrum of intermittent scanning, therefore, we adopt pulse, intermittent scanning red, green, blue visible spectrum is simulated irradiation, can make plant not have growth normally under the condition of sunshine, and the speed of growth is better than the plant under the solar light irradiation, we also find to need only the red of simulation, green, blue visible spectrum has pulse, the characteristic of intermittent scanning, when corresponding element atom outer-shell electron in spectral signal and the plant overflows merit spectrum when identical, and form certain burst arrangement scan action when plant, the plant growing signal system switch opens that 9 kinds of metallic elements such as inside plants potassium calcium iron copper are formed, plant is in optimum luminous environment growth conditions.(the scanning cycle pulse red, green, blue visible spectrum of simulation less than certain plants growth rate under the 2% solar irradiation energy condition much larger than with 100% sunlight conditions under the growth rate of this plant species.)
B). pulse period property scanning optical spectrum makes plant in photosynthetic process, and the energy ATP between photoreaction and the dark reaction is utilized fully, thus synthesis of organic substance, growth fast better.
C). light is as a kind of signal of opening the plant growing switch, and the pulsed illumination side in the pulse period property scanning optical spectrum environment is housed in the electronics ladder opening, and is used to discharge the energy of the ATP that combines with enzyme, has good effect.
