Isibane sokukhula kweLed luhlobo lwesibane esincedisayo ekukhuleni kwezityalo

Ukukhanya kwe-LED kukukhula kwesityalo esincedisa ukukhanya okulungiselelwe ngokukodwa ukuveliswa kweentyatyambo kunye nemifuno kunye nezinye izityalo ezidityaniswe nobuchwepheshe obuchanekileyo.Ngokuqhelekileyo, izityalo zangaphakathi kunye neentyantyambo ziya kukhula ngakumbi kwaye zibi kakhulu ekuhambeni kwexesha.Isizathu esiphambili kukungabikho kwe-irradiation yokukhanya.Ngokukhanyisa izibane ze-LED ezifanelekileyo kwi-spectrum efunwa zizityalo, ayikwazi nje ukukhuthaza ukukhula kwayo, kodwa nokwandisa ixesha leentyantyambo kunye nokuphucula umgangatho weentyatyambo.

Impembelelo yee-spectrum ezahlukeneyo ze-LED zikhula izibane

Izityalo ezahlukeneyo zineemfuno ezahlukeneyo ze-spectrum, ezifana nebomvu / eluhlaza okwesibhakabhaka 4: 1 ye-lettuce, 5: 1 yamaqunube, 8: 1 ngenjongo eqhelekileyo, kwaye ezinye zifuna ukunyusa i-infrared kunye ne-ultraviolet.Kungcono ukulungelelanisa umlinganiselo wokukhanya okubomvu nokuluhlaza okwesibhakabhaka ngokomjikelezo wokukhula kwesityalo.

Apha ngezantsi kukho isiphumo soluhlu olubonakalayo lwezibane ezikhulayo kwi-physiology yezityalo.

I-280 ~ 315nm: impembelelo encinci kwi-morphology kunye nenkqubo ye-physiological.

I-315 ~ 400nm: i-chlorophyll encinci yokufunxa, echaphazela umphumo we-photoperiod kunye nokukhusela i-stem elongation.

I-400 ~ 520nm (blue): i-absorption ratio ye-chlorophyll kunye ne-carotenoids yeyona inkulu, enempembelelo enkulu kwi-photosynthesis.

520 ~ 610nm (luhlaza): izinga lokufunxa kwebala alikho phezulu.

Ngokumalunga ne-660nm (obomvu): izinga lokufunxa i-chlorophyll liphantsi, elinempembelelo enkulu kwi-photosynthesis kunye nefuthe le-photoperiod.

720 ~ 1000nm: izinga lokufunxa eliphantsi, ukuvuselela ukwandiswa kweeseli, kuchaphazela ukudubula kweentyatyambo kunye nokuntshula kwembewu;

> 1000nm: iguqulwa ibe bubushushu.

Ke ngoko, amaza ahlukeneyo okukhanya aneempembelelo ezahlukeneyo kwi-photosynthesis yezityalo.Ukukhanya okufunekayo kwi-photosynthesis yesityalo kunobude obumalunga nama-400 ukuya kuma-720 nm.Ukukhanya ukusuka kwi-400 ukuya kwi-520nm (blue) kunye ne-610 ukuya kwi-720nm (ebomvu) inegalelo elikhulu kwi-photosynthesis.Ukukhanya ukusuka kwi-520 ukuya kwi-610 nm (eluhlaza) inezinga eliphantsi lokufunxa ngemibala yezityalo.
