Iziphumo zokukhanya kokukhula kwezityalo kukukhuthaza i-chlorophyll ukuba ifumane izondlo ezifana nekhabhoni kunye nekhabhoni ye-diokheli. Inzululwazi yale mihla inokuvumela izityalo zikhule ngcono kwiindawo ezingekho ilanga, kwaye ukudala imithombo yokukhanya kunokuvumela ukuba izityalo zigcwalise inkqubo ye-picynthetic. Igadi yale mihla okanye imicimbi yesityalo ebandakanya itekhnoloji yokukhanya eyongezelelweyo okanye itekhnoloji yokukhanya epheleleyo. Izazinzulu zifumanise ukuba imimandla eluhlaza okwesibhakabhaka kunye nebomvu isondele kakhulu kwi-curve ye-photosynthesis yesityalo, kwaye ingumthombo wokukhanya ofunekayo wokukhula kwezityalo. Abantu baye bafunda umgaqo wangaphakathi wokuba izityalo zifuna ilanga, ezi zezo foto. Ifotosinthesis yamagqabi ifuna uchulumanyo lweefoto zangaphandle ukuze ugqibezele yonke le nkqubo yefoto. Imisebe yelanga yinkqubo yokubonelela ngamandla enomdla kwiifoto.
Umthombo wokukhanya we-LED ukwabizwa ngokuba ngumthombo we-semiconductor. Lo mthombo wokukhanya une-wavelength emxinwa kwaye unokulawula umbala wokukhanya. Ukuyisebenzisa kwizityalo ezinganyanzelekanga kuphela kunokuphucula iintlobo zezityalo.
Ulwazi olusisiseko lokukhanya kwe-LED:
I-1. Amaza ahlukeneyo eendlela anazo iziphumo ezahlukeneyo kwifotosinthesis. Ukukhanya okufunekayo kwi-photosynthesis ye-photosynthesis kune-400-700nm. I-400-500nm (iblowu) ukukhanya kwaye i-610-720nm (ibomvu) igalelo kakhulu kwi-photosynthesis.
I-2. I-Blue (470NM) kunye ne-RED (i-630NM) i-LEDS inokubonelela ngokukhanya okufunekayo zizityalo. Ke ngoko, ukhetho olufanelekileyo kwizibane ze-LED kukusebenzisa indibaniselwano yezi ntlobo zimbini. Ngokweziphumo ezibonakalayo, izibane zendawo ezibomvu neziluhlaza okwesibhakabhaka zibonakala zipinki.
3. Ukukhanya okuluhlaza kunokukhuthaza ukukhula kwamagqabi aluhlaza; Isibane esibomvu siluncedo ekuqulekeni nasekuthiniyo kwaye songeza ixesha lokuntyatyambo.
I-4. Umyinge we-LEDS ye-Red kunye neBlue yeZibane zeZityalo ezi-LED iphakathi kwe-4: 1-9: 1, kwaye i-4-7: 1.
5. Xa izibane zezityalo zisetyenziselwa ukugcwalisa izityalo ezinokukhanya, ukuphakama kwamagqabi ngama-0.5 eemitha, kunye nokuvezwa okuqhubekayo kweeyure ezili-12 ukuya kwezi-12 ngosuku kungayifaka ilanga ngokupheleleyo.
Sebenzisa i-secondector ye-semicondcuctor ukuqinisekisa owona mthombo ulungileyo wokukhula kwezityalo
Izibane ezinemibala emiselweyo zinokwenza umlingane unokwenza i-strawberries kunye neetamatisi imnandi kunye nesondlo ngakumbi. Ukukhanyisa i-holly imbewu yokukhanya kukuxelisa iphophetha zezityalo ngaphandle. Iifotosinthesisi zibhekisa kwinkqubo apho izityalo eziluhlaza zisebenzisa amandla okukhanya nge-chloroplasts ukuguqula i-carbon diokside kwaye ikhuphe ioksijini. Ukukhanya kwelanga kudityaniswa imibala eyahlukeneyo yokukhanya, kunye nemibala eyahlukeneyo yokukhanya kunokuba neziphumo ezahlukeneyo ekukhuleni kwesityalo.
Izithole ezingcwele ezivavanywe phantsi kokukhanya kwesifuba mde, kodwa amagqabi ayencinci, iingcambu zazingakhathalelwanga. Izithole phantsi kombane otyheli azimfutshane kuphela, kodwa amagqabi abukeka aphile. I-holly ekhula phantsi kobomvu kwaye ukukhanya eluhlaza okwesibhakabhaka khula kakuhle, kungekuphela komelele, kodwa inkqubo yeengcambu iphuhlisiwe kakhulu. I-bulb ebomvu kunye ne-bulb eluhlaza okwesibhakabhaka yalo mthombo wokukhanya we-LED iqwalaselwe kumyinge we-9: 1.
Iziphumo zibonisa ukuba i-9: 1 i-1: i-1 ebomvu kunye neblue yeyona nto iluncedo kukukhula kwetyala. Emva kokuba lo mthombo wokukhanya unomthombo, i-strawberry kunye neziqhamo zetamatiyo ziyintonga, kwaye umxholo weswekile kunye nevithamini C inyuka kakhulu, kwaye akukho qhwa. I-Irradiation eqhubekayo yeeyure ezili-12 ukuya kwezi-12 ngosuku, amaqhinga kunye neetamatisi ezikhule phantsi komthombo wokukhanya onjalo ziya kuba nenciniba ngakumbi kuneziqhamo eziqhelekileyo zereredi.
