Description
Technical field
System of the present invention is about a kind of method of Promoting plant growth.The present invention is also about a kind of luminous flux accumulating calculation element and method.
Background technology
Photosynthesis with other self-operation property biologies, luminous energy is changed the process that (usually from the sun) becomes can be used for provide the chemical energy of the fuel of organism activity by plant.In the process, carbohydrate, as candy, system becomes from carbonic acid gas with hydration.Oxygen is also released, mainly as discarded object.Most plants, most of algae and blue-green alge carry out photosynthetic program, are called as photosynthetic autotroph.Photosynthesis maintains the oxygen content in air and provides the most of energy (except chemotrophy biology, it obtains energy by oxidation chemistry reaction) on the earth needed for all life.
Although photosynthesis carries out different process in different species, always the protein (comprising green chlorophyll pigment) that this process originates in when being called as reaction center from the energy of light absorbed.In plant, these protein are maintained in the born of the same parents' device being called chloroplast (there is maximum in leaf cells, be then be embedded in cell membrane in bacterium).In these light dependent responses, some energy are used to from suitable material, and such as water seizes electronics.This generates oxygen and hydrogen ion, it is transferred to the compound that is called Nicotine vinegar amine adenine-dinucleotide phosphoric acid (NADP+), makes it be reduced into NADPH.More light energy is transferred to generate adenosine triphosphate (ATP) in chemical energy, " energy currency " of cell.
Light have three basic sides to: between illumination period, light quantity and light quality.It is the time number of photoperiod or continuous illumination in every 24 hours between illumination period.Photoperiod regulates blooming of many chamber crops, and is simple about the lighting delay number of every day and the time number of dark.
Light quantity is for can perform photosynthetic smooth particle (being called photon) number.Light quantity is more complicated, because it can measure in two ways: the instant amount (luminous intensity) of light and transmit cumulant (day accumulated light) every day of light.Light quantity can be different unit measure, comprise footcandle (foot-candles), lux (lux), watt (Watts), micromole's rice-2S-1 (μm olm-2s-1) and mole rice-2d-1 (molm-2d-1).When being preferred for latter two unit during plant growth, because they quantize plant carry out photosynthetic ability, (respectively based on instant and every day).
Light particle has different energy.The energy of each smooth particle is decided by its wavelength.Light particle describes the three orientations-light quality of light in the relative populations of each wavelength.In other words, light quality refers to the relative populations of photon of spectrum of the spatial distribution of light or the blueness of launching from light source, green, redness, far red and other parts.This some of them part is visible, and other are not then.
Plant produces for light and the relative length in dark cycle and the intensity of light and quality and reacts.Artificial light has been widely used in the process controlling plant growth at different conditions.Plant is different in required light; Some grow up strong and sturdy under sunlight, and other grow best in the cool.Most plants can grow under nature or artificial light.Artificial light can use in the following manner: when needing to provide the light of high strength when improving plant growth, extend the time of natural daylight or provide Night-break to be in long-day conditions to maintain plant.
For plant, the only source of energy and information.It in photosynthesis as energy and it provide plant about needed for it as germinate, grow to a certain size or shape, eliciting protective material, to bloom and when from the important information of the environment of conversion of nourishing and growing.Plant for the quality of light, intensity, duration and direction make a response.
Except the visible light of the mankind (380 nanometer ~ 780 nanometer), plant also uses other radiation." photosynthesis Net long wave radiation " or PAR is called as in 400 nanometer ~ 700 nanometer wavelength range.Light needed for plant is many within the scope of this, but for the result of optimum growh, ultraviolet light (280 nanometer ~ 400 nanometer) and/or far-red light (700 nanometer ~ 800 nanometer) may be important.Such as, far-red light is vital for blooming of many plants.All light is unequal for plant, and that is, some regions are more important than other region.
A kind of artificial light source of grow light or plant spectrum, is generally a kind of electric light source, is designed to be applicable to carrying out photosynthetic electromagnetic spectrum grow with stimulating plant by launching.Grow light is not having natural daylight or is being used when fill-in light is required.Such as, sunshine duration time in the winter time may be not enough to make required plant growth, and grow light is used to extend the time that plant obtains illumination.
The control of the g and D of plant not only light reception intensity, the simultaneously control of also light income; In addition the time of irradiation also affects to some extent.The process system of photocontrol growth and development of plants is quite complicated.The capable photosynthesis of plant utilization visible ray, utilizes infrared light, and particularly 700 ~ 800 nanometers (nm) control the growth (morphogenesis) of phytomorph, and ultraviolet can be caused injury by bioprotein absorption.The generation of these reactions is through three major receptors systems (receptor system).Chlorophyll a and b absorb 640 nanometers respectively and 660 nano wave length light carry out photosynthesis, and phytochrome (Phytochrome) absorbs the many morphogenetic reactions of 660 and 730 nano wave length photocontrol; And flavine (flavin) absorbs 450 nano wave length light causes phototaxis (tropism) and high-energy photomorphogenesis (high-energyphotomorphogenesis).

Summary of the invention
Definition
Unless otherwise, " one (a) " or " one (an) " expression " one or many ".
Grow light attempts to provide the spectrum being similar to the sun, or provides a kind of spectrum be more suitable for required for plant cultivation.Export and change the light output (intensity) of lamp to imitate outdoor condition via different-colour and spectrum from grow light.Depend on cultivated vegetation type, stage of cultivation (such as, germination/vegetative phase or bloom/result the stage) and the photoperiod needed for plant, the spectrum of particular range, luminous efficacy and colour temperature can use in specified plant and period.
The lamp that exploitation is applicable to plant growth is the direction that this area is made great efforts always.In the present invention, applicant discloses a kind of straightforward procedure for stimulating plant growth.
Plant can the direction of sensing light, quality (wavelength), intensity and periodically.The formation of photoinduction phototropism, light form, Chloroplast differentiation and other various reactions, as bloomed and germinateing.Light quality sensed primarily of the light receptor for different wave length.Redness/far-red light receptor is called as phytochrome.Have 2 class blue light acceptors at least: procrypsis element (cryptochrome) identification blueness, green and UV-A light, and image assesment (phototropin) perception blue light.
The relation of light quality and development of plants, be disclosed in " Photomorphogenesis in Plant " (1986, Martinus Nijhoff Publishers) of G.H.M.Kronenberg, the impact of different spectral range on plant physiology is as shown in table 1.
Table 1, different spectral range are on the impact of plant physiology
| Spectral range | On the impact of plant physiology |
| 280-315 nanometer | Minimum on the impact of form and physiology course |
| 315-400 nanometer | Chlorophyll absorption is few, affects photoinductive cycles, stops stem to extend |
| 400-520 nanometer | Chlorophyll and carotenoid assimilation ratio maximum, photosynthesis is had the greatest impact |
| 520-610 nanometer | The absorption ratio of pigment is not high |
| 610-720 nanometer | Chlorophyll absorption rate is low, has significant impact to photosynthesis and photoinductive cycles |
| 720-1000 nanometer | Absorption ratio is low, and irritation cell extends, and impact is bloomed and seed sprouting |
| 1000 nanometers | Be converted into heat |
Generally generally believe that the color of light is different for photosynthetic impact, in fact in photosynthesis, the impact property of light color there is no difference.Full spectrum is used to be conducive to the growth of plant (Harry Stijger, Flower Tech, the 7th (2) phase in 2004) most.And plant is 400-700 nanometer to the sensitizing range that spectrum is maximum, this section spectrum is commonly referred to photosynthesis effective energy region.The energy of sunlight about has 45% to be positioned at this section of spectrum, and therefore the spatial distribution of plant growth light source also should close to this scope.
The photon energy of light source injection is different because wavelength is different, the such as energy of wavelength 400 nanometer (blue light) is 1.75 times of 700 nanometers (ruddiness) energy, but for photosynthesis, the exercising result of both wavelength is then identical, unnecessaryly in blue color spectrum then can not change heat into as photosynthetic energy.In other words, photosynthesis of plant speed is determined by the absorbent photon number of plant institute in 400-700 nanometer, and the photon number sent with each spectrum uncorrelated.Plant is for all spectrum, and its susceptibility is different, mainly because of the special absorbability of pigment in blade.Chlorophyll is the modal pigment of plant, but the pigment that chlorophyll is not uniquely useful to photosynthesis, and also have other pigments also can participate in photosynthesis, therefore photosynthetic efficiency can not only consider chlorophyllous absorption spectrum.For Form Development and the leaf color of plant, plant should receive the light source of various balance.Blue-light source (400-500 nanometer) to the differentiation of plant and the adjustment of pore very important.If blue light is not enough, the ratio of far-red light is too many, and stem will excessively grow up, and easily cause yellowing leaf.The ratio of red-light spectrum (655-665 nanometer) energy and far-red light spectrum (725-735 nanometer) energy is between 1.0 and 1.2, and the growth of plant is normal, but different plant is also different for the susceptibility of spectrum ratio.
