Actual Example:
You must to know
♦ Wavelength 280 ~ 315nm
This wavelength is already ultraviolet light. It has the function of direct repressive growth for all kinds of animals, plants and
even fungi, and has little influence on morphology and physiological processes.
♦ Wavelength 315 ~ 400nm
This kind of light wave is also a far-ultraviolet light. Although there is no ultraviolet damage to plants, it has no direct effect on
plant growth, and chlorophyll absorption is less, affecting photoperiod effect and preventing stem elongation.
♦ Wavelength 400 ~ 520nm (blue)
Such wavelengths can directly develop the roots and stems of plants, and have a large absorption ratio for chlorophyll and
carotenoids, and have a great influence on photosynthesis.
♦ Wavelength 520 ~ 610nm (green)
Green plant rejection push, the absorption rate of green pigment is not high.
♦ Wavelength 610 ~ 720nm (red)
The chlorophyll absorption rate of plants is not high, but this wavelength has a significant effect on photosynthesis and plant growth rate.
♦ Wavelength 720 ~ 1000nm
Such wavelengths are generally infra-red wavelengths, which have low absorption rates for plants and can directly stimulate
cell elongation, which may affect flowering and seed germination
♦ Wavelength >1000nm
The wavelength of the laser light that has been approached has been converted into heat.
