Description
Technical field
The present invention relates to lighting technical field, particularly relate to a kind of eight color LED lamp panel for plant growing。
Background technology
Current greenhouse culture technique is gradually general at home, and restriction point " illumination " of this technology is also in continuous improvement。
Many-sided advantages such as LED can be widely applied to plant culture, supplementing light for greenhouse, plant tissue culture, plant factor as plant illumination light source, has promotion plant growing, regulates phytomorph and builds up, energy-conserving and environment-protective。Not only can send the monochromatic light that light wave is narrower, such as ultraviolet light, blue light, green glow, HONGGUANG, far-red light etc., and combination in any can be needed according to plant difference, but also be the cold light source of low heat generation characteristic, it is possible to irradiation at short distance plant, improve space availability ratio。LED plant growth lamp can provide rational luminous environment condition for the growth of agro-ecology, reduces the use of the chemicals such as pesticide, hormone, it is ensured that food safety, is the green light source of low energy consumption。
The Chinese patent that one section of patent No. is 204176469U mentions " LED plant growth lamp ", including: lamp plate and 200 red LED lamp, 28 blue led lamps, 12 infrared LED lamps, 8 purple LED and 7 white led lamps that are welded on lamp plate, it is distributed in regularly on foursquare lamp plate。One of them white led lamps is at the center position of whole plank, and all the other 6 form hexahedral six summits around this central point；The LED of 8 purples separately constitutes two foursquare four summits varied in size with every 4 for one group round this central point；12 infrared LED lamps have then become a bigger square around this center so that each edge has 4 infrared LED lamps；All the other positions are all dispersed with regularly by red LED lamp and blue led lamp。This illuminator cannot realize the adjustment of brightness, and the LED of different colours is arranged as stated above and is easily caused lamp panel illumination brightness irregularities。
Northwest Botany Gazette 04 phase in 2010, writer's Liu Xiao English, Xu Zhigang, Chang Taotao, Guo Shirong, title: the different light medium LED low light level impact on cherry tomato plant forms and photosynthetic performance, have studied the impact on cherry tomato plant forms and photosynthetic performance of the different light medium low light level based on Novel LED light source。Result shows: add different photochromic process on the basis of (1) red blue light (RB), the form of plant is had no significant effect, but biomass has appreciable impact, the distribution of energy conditioning biomass。Except processing (Z) except the yellowish green purple complex light of red indigo plant, the individual plant total biomass that other complex light process both is greater than RB process, add green glow, gold-tinted, purple light and yellow purple light and be conducive to the growth in plant above ground portion, and add green glow and purple light suppresses the growth of plant underground part。(2), except processing except red blue yellow purple complex light (RBYP) and red royal purple complex light (RBP), the Contents of Photosynthetic Pigments of all process all processes high than RB, and it is the highest to process Contents of Photosynthetic Pigments with Z。(3) light compensation point of blade and AQY and Net Photosynthetic Rate are by the regulation and control of light quality。Maximum net photosynthetic rate and AQY that RBYP processes are noticeably greater than other and process, light compensation point is relatively big under red bluish-green complex light (RBG) and red blue yellow complex light (RBY), and less under white light (CK) and Z process。(4) the luminous energy distribution managing lightsystemⅡ everywhere there are differences, and it is little compared with other process that RB processes photochemical quenching coefficient, and the non-photochemical quenching coefficient of Z and RBP is less, and between each process, maximal photochemistry efficiency and electron transport rate are without significant difference。Research finds, photochromic the impact on vine growth and development of compound light quality is the relation of restriction collaborative, mutual mutually;It is bigger that red blue yellow purple complex light processes the photosynthetic potential of plant, it is possible to alleviates red blue Low Light Density Stress to a certain extent, promotes plant shoots growth;Red blue light basis added other photochromic accumulation being conducive to plant photosynthetic pigments and promotes photosynthetic, plant Photochemical Efficiency can be improved simultaneously。From the growth promoter of the combined effect plant of the known different light medium of the document and photosynthesis。
