[I-ABSTATRY] Ngokusekwe kwinani elikhulu ledatha yovavanyo, eli nqaku lixoxa ngemicimbi eliqela elibalulekileyo ekukhetheni imithombo yokukhanya, kubandakanya ukukhanya kwemithombo yokukhanya, iblowu ebomvu, kunye nokukhethwa kokukhanya Ranges, ukwenzela ukubonelela ngokuqonda kumgangatho wokukhanya kwiifektri zezityalo. Ukumiselwa kwesicwangciso esiliqili kubonelela ngezisombululo ezisebenzayo ezinokusetyenziselwa ukubhekiswa.
Ukukhetha umthombo wokukhanya

Iifektri zezityalo zisebenzisa izibane ze-LED. Kungenxa yokuba izibane ze-LED zineempawu zokusetyenziswa okuphakathi okuphezulu, ukusela amandla aphantsi, ukubekwa kobushushu obuncinci, ubomi obuncinci, obungayi kufezekisa iimfuno zokukhula kwezityalo kunye nokuqokelelwa kwezinto ezisebenzayo, kodwa zikondoloze amandla, Ukunciphisa ubushushu bokulala kunye neendleko zombane. Izibane zokukhulisa izibane zinokwahlulwa ngakumbi zizibane ezikhokelela kwi-chip ngokubanzi ze-chip ngokubanzi, i-chip-chip-the chip-chie-chie-chie-chie-chie-chie-chie-chie-chip edityanisiweyo-idibene nezibane ezikhokelayo. Ixabiso lezilwanyana ezimbini zokugqibela zezibane ze-LED ngokubanzi zininzi ngaphezulu kwamaxesha ama-5 kwizibane eziphithileyo ze-LED, ngoko imithombo yokukhanya eyahlukeneyo kufuneka ikhethwe ngokweenjongo ezahlukeneyo. Kwiifektri ezinkulu zezityalo, iintlobo zezityalo abazikhulisayo ziya kutshintsha ngemfuno yentengiso. Ukwenzela ukunciphisa iindleko zokwakha kwaye akuchaphazeli ukusebenza kakuhle kwemveliso, umbhali ucebisa ukuba asebenzise i-chips ebanzi ekhokelwe kwi-chips ngokubanzi njengomthombo wokukhanya. Kwizixhobo ezincinci zezityalo, ukuba iindidi zezityalo zilungisiwe, ukuze zifumane impumelelo kwimveliso ephezulu kunye nomgangatho ngaphandle kokukhulisa iindleko zokwakha, ukukhonkxa ngokubanzi zinokusetyenziswa njengomthombo wokukhanyisa. Ukuba kukufundisisa isiphumo sokukhanya kwezityalo ngokukhula kwezityalo kunye nokuqokelelwa kwezinto ezilula, ukuze kunikezwe ifomula ekhanyayo yexesha elizayo, indibaniselwano ye-chii ezininzi zezibane ezinokuphinda zitshintshe Izinto ezifana nobunzulu bokukhanya, imbonakalo kunye nexesha lokukhanya ukufumana ifomula ekhanyayo yesityalo ngasinye kwisiseko semveliso enkulu.

Ukukhanya okubomvu kunye neblue

Ukuya kuthi ga ngoku iziphumo ezithile zovavanyo zichaphazelekayo, xa umxholo wokukhanya obomvu (R) uphakame ngaphezu kwelokhanya oluhlaza (B) (i-L) (i-L) (i-L) (i-Lettuce R: B = 4: 4: 4: I-1; imbewu ye-gourd R: b = 7: 3; I-Ccumbber imbewu R: B = 7: 3), uvavanyo lubonise ukuba umxholo we-biomass ubonise umxholo we-biomass (elona nqanaba liphezulu lendawo, Ubunzima obutsha kunye nobunzima obutsha, njl njl. Kwizalathisi ze-biochemical, umxholo wokukhanya obomvu ungaphezulu kunobuncinci obukhanyiso luyingenelo ngokubanzi kukunyuka komxholo weswekile enyibilikisi kwizityalo. Nangona kunjalo, ukuqokelela iproteni ye-VC, iproteni enyibilikayo, i-chlorophyll kunye ne-carotenoids kwizityalo, kuyingenelo ngakumbi ukusebenzisa ukukhanya kwe-Blue enomxholo obomvu, kwaye umxholo we-malondirialdehyde naphantsi kwemeko yokukhanya.

Kuba umzi-mveliso wezityalo ikakhulu usetyenziselwa ukuhlakulela imifuno enamagqabi okanye ukuphakamisa imizi-mveliso, kunokugqitywa kwezi ziphumo zokwandisa isivuno kwaye kuthathelwa ingqalelo ekusebenziseni i-chips ekhokelweyo umxholo wokukhanya kunobuncinci obukhali njengoMthombo wokukhanya. Umyinge ongcono ngu-R: B = 7: 3. Yintoni engaphezulu, umlinganiselo onjalo obomvu kunye noblowu busebenza kuzo zonke iintlobo zemifuno enamagqabi okanye kwimifuno enamagqabi okanye imbewu, kwaye akukho mfuneko ethile yezityalo ezahlukeneyo.

I-Red kunye neBlue Waveledth

Ngexesha lefotosinthesisi, amandla okukhanya ikakhulu ingene ikakhulu kwi-chlorophyll a kunye ne-chlorophyll b. Umzobo ongezantsi ubonakalisa ukufunxa i-chlorophyll A kunye ne-chlorophyll B, apho i-chlorophyll B, apho iluhlaza iluhlaza i-hlorophyll a, kwaye i-chlorophyll i-chlorophyl ye-chlorophyll b. Ingabonwa kumzobo omabini i-chlorophyll A kunye ne-chlorophyll B zineencopho ezimbini zokukhanya, enye kwingingqi eluhlaza okwesibhakabhaka kunye nenye kwingingqi ebomvu. Kodwa i-2 yeencopho ezi-2 ze-chlorophyll a kunye ne-chlorophyll b zahluke kancinci. Ukuchaneka, amaza amabini e-chiak ye-chlorophyll A zingama-430 NM kwaye i-662 NM, kunye namaza amabini e-chlorophyll B angama-453 NM, ngokwahlukeneyo. La maxabiso amane amagqabi angaguquki ngezityalo ezahlukeneyo, ke ukukhetha amaza abomvu kunye aluhlaza okwesibhakabhaka kumthombo wokukhanya akuyi kutshintsha ngeentlobo ezahlukeneyo zezityalo.

Ukufunqwa i-hlorofyll a kunye ne-chlorophyll b

Isibane esiqhelekileyo se-LEDS esine-spectum sinokusetyenziswa njengoMthombo wokukhanya womzi-mveliso wezityalo, ixesha elide njengoko ukukhanya okubomvu kunye neblue kunokuhlawula amaza amabini e-chlorophyll a kunye ne-chlorophyll B, oko kukuthi, i-wavelethth yaqala ukukhanya Iminyaka engama-620 ~ 680 nm, ngelixa ukukhanya eluhlaza okwesibhakabhaka i-wavelength yavela kwi-400 ukuya kwi-480 NM. Nangona kunjalo, i-wavelength yavelela ibomvu kwaye iblowu ukukhanya akufuneki ukuba ibe kakhulu kuba ingabinamandla nje, kodwa inakho nakwezinye iimpembelelo.

Ukuba ukukhanya kwe-LED equlunqwe nge-chips ebomvu, etyheli kunye neblue isetyenziswa njengoMthombo wokukhanya womzi-mveliso wezityalo, i-Peak Wavemeth ye-CHLOPYLL A, nge-660 NM, i-Peak Wavelethth Isibane esiluhlaza kufuneka sibekwe kwi-chlorophyll b, okt nge-450 NM.

Indima ye-Yellow kunye neGreen

Ifanelekile ngakumbi xa umyinge we-RED, eluhlaza kunye noluhlaza okwesibhakabhaka yi-R: G: B = 6: 1: 3. Ngokuphathelele ukumiselwa kwe-Green High Lavelength, kuba idlala indima elawulayo kwinkqubo yokukhula kwezityalo, kufuneka iphakathi kwe-530 kunye ne-550 NM.

Isishwankathelo

Eli nqaku lixoxa ngesicwangciso sokukhetha umgangatho wokukhanya kwiifektri zezityalo ukusuka kuzo zombini ii-themoretical and ezisebenzayo, kubandakanya ukukhanya kwe-waveleth kunye ne-Blue ukukhanya kunye nendima ye-tyheli. Kwinkqubo yokukhula kwezityalo, ukuthelekisa okufanelekileyo phakathi kwezi zinto zintathu zokukhanya, ukuphazamiseka okukhanyayo kunye nexesha lokukhanya, kunye nolwalamano lwabo kunye nezakha-mzimba, kunye ne-CO2 kufuneka ziqwalaselwe ngokupheleleyo. Ngokwemveliso yokwenene, nokuba uceba ukusebenzisa i-spectrum ebanzi okanye indibaniselwano ye-chip ekhokelela ekuqwalaselweni, umyinge wamaza oluyintloko, kuba ukongeza kumgangatho wokukhanya, ezinye izinto zinokulungiswa ngexesha lokwenyani ngexesha lokusebenza. Ke ngoko, eyona nto iphambili ekuqwalaselweni kwinqanaba loyilo lweefektri zezityalo kufuneka kukhetho lomgangatho wokukhanya.
