Abstract
The invention provides a method for reducing the influence of ambient lighting on plant growth in a plant factory. When a plant is in the dark stage of a photoperiod, the luminescence spectrum of an ambient light source is located outside the sensitive area of photosynthetic pigments in the plant. The invention provides a method for reducing the influence of ambient lighting on plant growth in a plant factory, so that the interference to plant photoperiod caused by ambient lighting is greatly reduced.
Description
Technical field
The present invention relates to a kind of reduce the method that ambient lighting affects on plant growth in plant factor.
Background technology
The advanced form that artificial light type plant factor develops as agricultural modernization facility, is substituted completely using artificial light source
Sunshine meets the growth demand of plant, and light intensity, light quality, photoperiod are special to plant forms, chlorophyll content in leaf blades, photosynthesis
Property, yield and quality have a major impact, particularly importantly：It is related to staff's working environment in artificial light type plant factor
Lighting environment, the spectrum form of common lighting source is as shown in Figure 1：
And in plant photosynthetic pigments (such as Chlorophylls and Carotenoids) activity, it is most of with photosynthesis in
The absorption of light is relevant with energy transmission.Chlorophyll has maximum at blue light region (380nm-460nm) and red light district (600nm-700nm)
Sensitiveness, carotenoid, such as lutein and carrotene, as chlorophyllous auxiliary photoreceptor, mainly absorb blue light, such as
Shown in Fig. 2.
Contrast Fig. 1 and Fig. 2, it is known that, when plant is in the dark phase in the photoperiod, if the now illumination light of working environment
Source works, and will pass out chlorophyll or other dye-sensitized red blue light signals, disturbs the photoperiod of plant, breaks its life
The long rhythm and pace of moving things, affects morphogenesis, yield and quality of plant etc..The problems referred to above in solve plant factor, we have developed one kind
Dedicated for working environment lighting source in plant factor.
The content of the invention
Technical problem underlying to be solved by this invention is to provide ambient lighting in a kind of reduction plant factor and plant is given birth to
The long method for affecting, interference of the ambient lighting light to the plant photoperiod is substantially reduced.
In order to solve above-mentioned technical problem, the invention provides ambient lighting is given birth to plant in a kind of reduction plant factor
The long method for affecting, when plant is in the dark phase in the photoperiod, the luminescent spectrum of ambient lighting light source is photosynthetic in plant
Outside the sensitizing range of pigment.
In a preferred embodiment：When plant is in the dark phase in the photoperiod, the luminous light of the ambient lighting light source
Spectrum coverage is 460-600nm.
In a preferred embodiment：In the luminescent spectrum of the ambient lighting light source, wavelength is the spoke of 505-580nm parts
Penetrate luminous power accounting >=80%.
Compared to prior art, technical scheme possesses following beneficial effect：
Ambient lighting method that plant growth is affected in a kind of reduction plant factor that the present invention is provided, by by environment
The luminescent spectrum of lighting source is arranged in plant outside the sensitizing range of photosynthetic pigments.Therefore, it is in the photoperiod in plant
During the dark phase, even if staff opens ambient lighting light source, impact of the light that it sends to photosynthetic pigments is also very little.Cause
This, will not destroy the plant normal photoperiod, would not also break the normal growth rhythm of plant.Plant can effectively be lifted
Yield and quality.

Scope is 460-600nm, and its medium wavelength is 89.93% for the radiation luminous power accounting of 505-580nm parts, as shown in Figure 4.
Embodiment 3
The present embodiment is with the difference of embodiment 1, and in the present embodiment, the luminescent spectrum of the ambient lighting light source is covered
Scope is 460-600nm, and its medium wavelength is 81.84% for the radiation luminous power accounting of 505-580nm parts, as shown in Figure 5.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any those familiar with the art the invention discloses technical scope in, the change or replacement that can be readily occurred in,
All should be included within the scope of the present invention.Therefore, protection scope of the present invention should be with scope of the claims
It is defined.
