I-LED grow light ukukhanya okuyisizayo kokukhula kwesitshalo okuklanyelwe ngokukhethekile ukukhiqizwa kwezimbali nemifino nezinye izitshalo kuhlanganiswe nobuchwepheshe obunembayo.Ngokuvamile, izitshalo nezimbali zasendlini zizokhula zibe zimbi kakhulu ngokuhamba kwesikhathi.Isizathu esiyinhloko ukuntuleka kokukhanya kwe-irradiation.Ngokukhanyisa izibani ze-LED ezifanele i-spectrum edingwa izitshalo, ayikwazi nje ukukhuthaza ukukhula kwayo, kodwa futhi yandise isikhathi sokuqhakaza futhi ithuthukise ikhwalithi yezimbali.
Umthelela wama-spectrum ahlukene wezibani ezikhulayo ze-LED
Izitshalo ezihlukene zinezidingo ezihlukene ze-spectrum, ezifana no-4:1 obomvu/oluhlaza okwesibhakabhaka kuulethisi, u-5:1 wama-strawberry, u-8:1 ngokwenjongo evamile, kanti ezinye zidinga ukwandisa i-infrared ne-ultraviolet.Kungcono ukulungisa isilinganiso sokukhanya okubomvu nokuluhlaza ngokuhambisana nomjikelezo wokukhula kwesitshalo.
Ngezansi umphumela we-spectral range of grow light on plant physiology.
280 ~ 315nm: ithonya elincane ku-morphology kanye nenqubo yokuphila.
315 ~ 400nm: ukumuncwa kwe-chlorophyll okuncane, okuthinta umphumela we-photoperiod futhi kuvimbele ukunwetshwa kwesiqu.
400 ~ 520nm (okuluhlaza okwesibhakabhaka): isilinganiso sokumuncwa kwe-chlorophyll ne-carotenoids sikhulu, esinomthelela omkhulu ku-photosynthesis.
520 ~ 610nm (okuluhlaza): izinga lokumuncwa kwe-pigment aliphezulu.
Cishe ku-660nm (obomvu): izinga lokumuncwa kwe-chlorophyll liphansi, elinomthelela omkhulu ku-photosynthesis kanye nomphumela we-photoperiod.
720 ~ 1000nm: izinga lokumunca eliphansi, elikhuthaza ukunwetshwa kwamaseli, lithinta ukuqhakaza nokuhluma kwembewu;
> 1000nm: iguqulelwe ekushiseni.
Ngakho-ke, amaza ahlukene okukhanya anemiphumela ehlukene ku-photosynthesis yezitshalo.Ukukhanya okudingekayo ku-photosynthesis yezitshalo kunobude begagasi obungaba ngu-400 kuya ku-720 nm.Ukukhanya kusuka ku-400 kuya ku-520nm (okuluhlaza okwesibhakabhaka) kanye no-610 kuya ku-720nm (obomvu) kunomthelela omkhulu ku-photosynthesis.Ukukhanya okusuka ku-520 kuya ku-610 nm (okuluhlaza) kunezinga eliphansi lokumuncwa yimibala yezitshalo.
