Description
Technical field
The present invention relates to a kind of plant growth regulating lamp with specific blend spectrum that can promote plant to emerge and grow.
Background technology
Plant need carry out photosynthesis provides the needed nutriment of self growing, and light is most important to the influence of plant.The spectrum of sunshine is continuous, has comprised great spectrum width, and plant only need to absorb fraction wherein, the absorption of sunshine is mainly concentrated on the visible light part.Specific as follows: chlorophyll-a, 435 ± 15nm, low luminous energy 555 ± 15nm, 660 ± 15nm (mixed light pixel unit); Chlorophyll-b, 455 ± 10nm, low luminous energy 550 ± 10nm, 640 ± 10nm (mixed light pixel unit); Solatene, 450 ± 10nm, 475 ± 10nm, low luminous energy 555 ± 15nm and 640 ± 10nm (mixed light pixel unit); Red plant growing is main with higher blue light energy, has points of resemblance with solatene spectrum, also has required like phycoerythrin and phycocyanin etc.In order to promote photosynthesis of plants; Simulating plant optimum growh photoenvironment carries out light filling irradiation to plant, provide plant to absorb the illumination of spectral coverage, improve the illumination condition of crops; Make plant also can carry out photosynthesis, grow to promote it in night or cloudy day.
Chinese patent publication number CN101133707A discloses a kind of method and device thereof that utilizes the led light source coordinate plant growth on March 5th, 2008 " be confirm to utilize red, blueness and purple LED to be radiation source according to the plant chlorophyll absorption spectrum, by the mixed light of different LED plant is shone.It is the fluorescent tube that adopts blueness and/or red light group that Chinese patent publication number CN2453674Y discloses a kind of " promoting the photosynthetic fluorescent tube of plant growing " October 17 calendar year 2001.More than two patents only relate to all that the wavelength of broad is red, the fluorescent tube combination of blueness and purple; And all do not mention its intensity of illumination (being the luminous energy peak value), reach green range; And that the illumination of different illumination intensity is penetrated the influence of plant growing and composition is also inequality, thereby it promotes that the effect of growth and development of plants is limited.
Summary of the invention
A kind of plant seed germination time and the maturation time of shortening greatly that the objective of the invention is to overcome above-mentioned shortcoming and provide, energy consumption is low, the plant growth regulating lamp that cost is low.
Plant growth regulating lamp of the present invention, its mixed spectra comprise spectral wavelength 440 ± 20nm, luminous energy peak value 93% ± 7%; Spectral wavelength 550 ± 20nm, luminous energy peak value 90% ± 5%; Spectral wavelength 660 ± 30nm, luminous energy peak value 95% ± 5%.
Above-mentioned plant growth regulating lamp, wherein: mixed spectra also comprises spectral wavelength 415 ± 5nm, luminous energy peak value 50% ± 15%
Above-mentioned plant growth regulating lamp, wherein: lamp can adopt fluorescent lamp, the electrodeless lamp of high-frequency/low-frequency or LED lamp.
The present invention compared with prior art; Has tangible beneficial effect; Can know from above technical scheme; Well-illuminated according to required mixing navy blue, blueness, green and the red spectrum of plant seed germination and process of growth and light is radiation source; Confirm the light pixel unit according to the bud seedling to the spectral energy ratio of these four kinds of colors is required, with the operating current or the light source irradiation allocative efficiency of electronics or mix the allotment of fluorescent powder utilization and produce its required photoeffect and light well-illuminated, to plant seed or carry out the irradiation of 16 ~ 19 hours every days vegetative period.Obtain best plant seed or the best photosynthesis of growth photoenvironment to get, it is low to shorten plant seed germination time and maturation time and energy consumption greatly, and cost is low.
Below further specify beneficial effect of the present invention through embodiment.
Embodiment
