The principle of plant growth lamp

- Sep 12, 2018-

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
