Specific embodiment
For the advantage of the present invention of explanation further, do explanation further in the face of invention down.
Through for a long time test, having listed influences the topmost five kinds of light of plant growing, that is: white light, ruddiness, blue light, infrared light, green glow.They play a different role respectively.
White light: be used to promote the growth of limb;
Ruddiness: promote the growth of leaf;
Blue light: suppress the effect at florescence;
Infrared light: promote plant growing;
Green glow: advance the plant growing of algae class.
According to research, light is to plant generation effect, and the wavelength in purple light district system is 400nm～420nm scope; Blue light region wavelength system is 440nm～470nm scope; Green Region specific wavelength system can be 520nm～555nm scope; With red light district specific wavelength system is between 640nm～660nm; Infrared light district specific wavelength system can be 735nm～850nm scope; The white light area colour temperature is in 5000～10000K scope.Light source of the above, the ratio of its specific; so that different colors of LED light of different wavelengths section, and then the different plants, different growth period, a combination of optimum brightness? The specific color of the LED light source wavelength spectrum lights, to produce a specific wavelength of light irradiation plants, to promote or control plant growth needs.
Embodiment 1
The effect of present embodiment is mainly used in the promotion botanical seedling culturing, will determine the growth of plant during this period, and therefore should it be carried out comprehensive proportioning during this period: it is chip used; The ratio of white light, ruddiness, blue light, infrared light is 2～15: 2～15: 2～15: 1～2; In this ratio range, no matter be between nursery stage, the growth of seedling bud itself; Also later to plant growth all will be played crucial effects.According to the difference of different facial plant planting area, select the proportioning that adapts.For more convenient to use, more be applicable to more plant growing, it is chip used, and the ratio of white light, ruddiness, blue light, infrared light is adjusted into 4: 4: 4: 1.The ratio of white light, ruddiness, blue light, four kinds of light of infrared light is relative like this, and all more suitable for general plant, the user is convenient when proportioning.
Embodiment 2
Foregoing invention is done further to improve; For the plant of let us gets into the florescence early, its objective is to promote healthy and strong coring development, long shoot leaf, kind of blooming period prolonging; Therefore we are chip used, and the ratio of white light, ruddiness, blue light, infrared light is 5～20: 4～16: 2～8: 2～4.This ratio makes the early growth that can quicken plant, gets into the florescence in advance.For some ornamental plants, we let it get into the florescence in advance in addition, its objective is in order to prolong its florescence; And be not only in order to let it bloom in advance, therefore, we have done further screening again in this ratio; With chip used; The ratio of white light, ruddiness, blue light, infrared light is adjusted into 5: 4: 2: 2, when plant gets into the florescence and then is adjusted into aforementioned proportion, just can prolong its time at florescence.
Embodiment 3
The main effect of present embodiment is only to be to promote flowering of plant, owing to promote to bloom, main purpose is promotion healthy and strong coring development, long shoot leaf, blooms in advance.According to this principle, we have made following proportioning: it is chip used, and white light, ruddiness, blue light ratio are 8～16: 1～2: 2～8.Foregoing invention is done further to improve, and it is chip used, and infrared light, blue light, ruddiness ratio are 4: 1: 8; This technology ratio can let plant get into the florescence according to the Changes in weather in this season in advance.
Embodiment 4
The main effect of present embodiment is to suppress the florescence, lets its long shoot leaf, for a lot of plants; It is unimportant to bloom; Important is flourishing, and therefore made following proportioning to this type plant: it is chip used, and white light, ruddiness, blue light ratio are 8～16: 8～16: 2～8.In addition, treat that the florescence just can be adjusted into 5: 4: 4 with the ratio of its chip used white light, ruddiness, blue light later.This ratio helps the shoot and leaf growth of plant.As it is replaced with, it is chip used, and white light, blue light, ruddiness ratio are 8: 1: 4.This ratio is when plant growing, promotes the limb growth.
Embodiment 5
The main effect of this enforcement is the growth that promotes limb; Let long not only thick but also strong of limb; This technical scheme is particularly suitable for woody plant, and therefore made following proportioning to this type plant: it is chip used, and infrared light, ruddiness, blue light ratio are 4～8: 8～16: 1～2.The light of this combination can play facilitation to growing of limb in the whole growth process of plant always.Except long thick, also to find chip usedly with it, infrared light, ruddiness, blue light ratio are adjusted into: 4～8: 4～8: 1～2 o'clock; Can also promote growing tall of limb, said ratio is replaced by, chip used; Infrared light, ruddiness, blue light ratio are 4: 8: 1 o'clock, then promote shoot and leaf growth.
With this invention, the ratio of the spectrum of the LED lamp mode, a combination of the best luminance of specific color wavelength light source LED lights; able to home potted plants, indoor plants cultivation, growth of aquatic plants and lighting, greenhouses and other application environments, plant growth for low light or at night to increase light; and controlled plant factory of its specific wavelength of light irradiation on plants, to promote or control plant growth needs.
