Isiphumo sokukhanya ekukhuleni kwesityalo kukukhuthaza iklorofili yesityalo ukuba ifunxe izondlo ezifana nekhabhon diokside kunye namanzi ukwenza icarbohydrates.Inzululwazi yale mihla inokuvumela izityalo ukuba zikhule bhetele kwiindawo ezingenalanga, kwaye ukwenza imithombo yokukhanya ngokwemvelo kunokuvumela izityalo ukuba zigqibezele inkqubo yephotosynthetic.Iifektri zegadi zanamhlanje okanye zezityalo zibandakanya itekhnoloji yokukhanya eyongezelelweyo okanye itekhnoloji yokukhanya epheleleyo eyenziweyo.Izazinzulu zifumanise ukuba imimandla eluhlaza nebomvu isondele kakhulu kwigophe elisebenzayo lephotosynthesis yezityalo, kwaye ingumthombo wokukhanya ofunekayo ekukhuleni kwezityalo.Abantu baye bawuqonda kakuhle umgaqo ofunekayo wezityalo ukuze elangeni, obizwa ngokuba yiphotosynthesis yamagqabi.Ifotosynthesis yamagqabi ifuna uchulumanco lweefotoni zangaphandle ukugqiba yonke inkqubo yephotosynthetic.Imitha yelanga yinkqubo yokunikezelwa kwamandla echulumanciswa ziifotoni.
Umthombo wokukhanya we-LED ukwabizwa ngokuba ngumthombo wokukhanya we-semiconductor.Lo mthombo wokukhanya unobude obumxinwa ngokwentelekiso kwaye unokulawula umbala wokukhanya.Ukuyisebenzisela ukunkcenkceshela izityalo kuphela kunokuphucula iintlobo zezityalo.
Ulwazi olusisiseko lokukhanya kwezityalo ze-LED:
1. Ubude obuhlukeneyo bokukhanya buneziphumo ezahlukeneyo kwifotosynthesis yezityalo.Ukukhanya okufunekayo kwi-photosynthesis yesityalo kunobude obumalunga ne-400-700nm.I-400-500nm (blue) ukukhanya kunye ne-610-720nm (bomvu) inegalelo elikhulu kwi-photosynthesis.
2. Ii-LED eziluhlaza okwesibhakabhaka (470nm) kunye nobomvu (630nm) zinokubonelela nje ngokukhanya okufunwa zizityalo.Ke ngoko, ukhetho olufanelekileyo kwizibane zezityalo ze-LED kukusebenzisa indibaniselwano yale mibala mibini.Ngokweempembelelo ezibonakalayo, izibane zezityalo ezibomvu neziluhlaza zibonakala zipinki.
3. Ukukhanya okuluhlaza kunokukhuthaza ukukhula kwamagqabi aluhlaza;ukukhanya okubomvu kunceda ukudumba kunye neziqhamo kunye nokwandisa ixesha leentyatyambo.
4. Umlinganiselo wee-LED ezibomvu neziluhlaza okwesibhakabhaka zezibane zezityalo ze-LED ziphakathi kwe-4: 1--9: 1, kwaye ngokuqhelekileyo 4-7: 1.
5. Xa izibane zezityalo zisetyenziselwa ukugcwalisa izityalo ngokukhanya, ukuphakama ukusuka kumagqabi ngokuqhelekileyo malunga neemitha ezi-0.5, kwaye ukubonakaliswa okuqhubekayo kweeyure eziyi-12-16 ngosuku kunokutshintsha ngokupheleleyo ilanga.
Sebenzisa iibhalbhu ze-semiconductor ze-LED ukumisela owona mthombo wokukhanya ufanelekileyo wokukhula kwezityalo
Izibane ezinemibala ebekwe ngokomlinganiselo zinokwenza amaqunube kunye neetumato zibeswiti kwaye zibe nesondlo ngakumbi.Ukukhanyisa izithole ze-holly ngokukhanya kukuxelisa i-photosynthesis yezityalo ngaphandle.I-Photosynthesis ibhekisa kwinkqubo apho izityalo eziluhlaza zisebenzisa amandla okukhanya ngeekloroplasts ukuguqula ikharbon diokside kunye namanzi zibe ngumthombo ogcina amandla kwaye zikhuphe ioksijini.Ukukhanya kwelanga kubunjwe ngemibala eyahlukeneyo yokukhanya, kwaye imibala eyahlukeneyo yokukhanya inokuba neziphumo ezahlukeneyo ekukhuleni kwezityalo.
Izithole zeholly ezivavanyiweyo phantsi kokukhanya okumfusa zakhula zaba nde, kodwa amagqabi ayemancinci, iingcambu zazingekho nzulu, kwaye zikhangeleka zingondlekanga.Izithole phantsi kokukhanya okutyheli azikho mfutshane nje kuphela, kodwa amagqabi abonakala engenabomi.I-holly ekhula phantsi komxube obomvu kunye nokukhanya okuluhlaza okwesibhakabhaka ikhula kakuhle, kungekhona nje kuphela yomelele, kodwa inkqubo yeengcambu nayo iphuhliswe kakhulu.Ibhalbhu ebomvu kunye nebhalbhu ebhlowu yalo mthombo wokukhanya we-LED zibunjwe ngokomlinganiselo we-9:1.
Iziphumo zibonisa ukuba ukukhanya kwe-9: 1 okubomvu nokuluhlaza okwesibhakabhaka yeyona nto inenzuzo ekukhuleni kwezityalo.Emva kokuba lo mthombo wokukhanya uhlanjululwe, iziqhamo ze-strawberry kunye ne-tomato zigcwele, kwaye umxholo weswekile kunye ne-vitamin C unyuswa kakhulu, kwaye akukho nto ingenanto.I-irradiation eqhubekayo kwiiyure eziyi-12-16 ngosuku, i-strawberries kunye neetamatato ezikhulile phantsi komthombo onjalo wokukhanya ziya kuba mnandi ngakumbi kuneziqhamo eziqhelekileyo ze-greenhouse.
