The principle of plant growth lamp

Light environment is one of the important physical environment factors indispensable to plant growth and development.

Effects of spectral range on plant physiology:

The effect of 280nm ~ 315nm on morphology and physiological processes was minimal

Chlorophyll absorption of 315 nm~ 420nm is less, which affects photoperiod effect and prevents stem elongation

The absorption ratio of 420 nm~ 500nm (blue) chlorophyll and carotenoid was the largest, which had the greatest impact on photosynthesis

The absorption rate of 500 nm~ 620nm pigment is not high

The chlorophyll absorption rate of 620nm ~ 750nm (red) was "high", which had significant influence on photosynthesis and photoperiodic effect

Low absorption of 750nm ~ 1000nm can stimulate cell elongation and affect flowering and seed germination

 >1000nm turns into heat
