Makhe sithethe ngendima yokukhanya kwesityalo se-LED-UVA, ukukhanya okuluhlaza okwesibhakabhaka, ukukhanya okubomvu-okumhlophe, kunye nokukhanya okubomvu.
Ezi zilandelayo zizifundo ezibini ezitsha ngokwentelekiso, esinye sisixhobo esitsha sokulinywa kwe-basil, kwaye esinye sisspectrum sokulinywa kwe lettuce. Ukuba unomdla, ungabhekisa kumaphepha abo.
Sinezibane ngokwesiseko ezifanayo nezi spectra zimbini. Ukuba sitshintsha ubude be-LED obufanelekileyo, banokuphantse bafane.
Ndiya kuthelekisa ezi zimbini ze-spectra kunye ne-spectrum yobuntu (echazwe kamva) ukubona umehluko. Izityalo ezikhuliswayo zikwayilethisi kunye nebasil.
Makhe sithethe malunga ne-basil yokutyala kuqala

Olu luphononongo lwaseBritane. Esona sigqibo sesokuba ukukhanya kwe-435nm blue kuluncedo kakhulu ekukhuleni kwezityalo kunokukhanya okuluhlaza kwe-450nm!
Umlinganiselo obomvu-blue we-spectrum kulo mfanekiso ungentla ngu-1: 1.5 (1.4). Ukuba ibalwe ngokwangoku, yi-1:1;
Ndixhalabele ngakumbi malunga nejika lokufunxa ukukhanya kwe-basil eswiti, bona uMfanekiso 2.
Umzobo 2 Igophe lokufunxa elikhanyayo le-basil eswiti
Kumzobo, isenako ukufunxa ukukhanya okuninzi ngaphantsi kwe-400nm. Ndinethuba lokwenza umfuniselo ngezibane ezingama-340nm. Izibane ze-340nm zibiza kakhulu.
Ngokwe-curve yokufunxa ukukhanya kwe-basil, ngaba oku kuya kuba ngcono kune-spectrum ye-435nm: 663nm?
Isixhobo sokutyala iilethisi

Olu luphononongo lwaseTshayina. Isiphelo esiphambili sesokuba kwixesha elithile, ukwanda kokukhanya kwe-UVA kunokuphucula kakhulu isivuno kunye nomgangatho wezityalo ze lettuce.

Le spectrum ilingana ne-F89 yethu, kunye neeyantlukwano ezithile kwicandelo le-UVA.
Kuya kubakho ii-spectra ezi-2 ezithatha inxaxheba kuvavanyo lolawulo, zombini ezo zongeza ukukhanya kobuntu, oko kukuthi, nobubele ebantwini, ubuncinci ungabona ngokucacileyo. Njengoko besitshilo, izinto ezi-5 eziphambili zezibane zezityalo:
Kwaye iHorti Guru, inkqubo yokulawula ukukhanya kwezityalo.
I-Ultraviolet A (UVA) inobude obuyi-320-400nm kwaye yenza malunga ne-3% yeefoton ezidlula kwi-atmosfera yomhlaba kukukhanya kwelanga kwendalo. Ukukhanya kwe-UVA kwezityalo akuyonakalisi i-DNA
I-UV ibonakaliswe ukuba yonyusa izixa ze-THC, i-CBD, kunye nemveliso ye-terpene kwizityalo ze-cannabis
I-UVA isanyusa ukuveliswa kweemetabolites zesibini ezifana ne-THC, i-CBD, i-terpenesand flavonoids kodwa ngaphandle kwemiphumo emibi yokukhanya kwe-UVB.
Imitha ye-UVA inceda isivuno kunye nomgangatho welettuce yangaphakathi

Iswekile enyibilikayo kunye nomxholo weprotheyini
Umxholo we-Phenolic kunye ne-flavonoid
Umxholo weAnthocyanin
Umxholo we-Malondialdehyde (MDA).
Umxholo we-ascorbic acid
Amagqabi akhule phantsi kwe-UVA abonise umxholo ophezulu we-anthocyanin
I-UVA yandisa umsebenzi we-SOD kunye ne-CAT
I-UVA inokunyusa imveliso ye-biomass
Ukongezwa kwe-UVA kwindawo elawulwayo akugcini nje ukuvuselela ukuveliswa kwe-biomass (Iitheyibhile 2 kunye ne-4), kodwa kwaphucula umgangatho wesondlo se-lettuce (Iitheyibhile 3 kunye ne-5). ）
Apha, sibonisa ukuba ukongeza i-UVA kwindawo elawulwayo akugcini nje ukuvuselela i-biomassproduction (Iitheyibhile 2 kunye ne-4), kodwa iphucula umgangatho wesondlo se-lettuce (Iitheyibhile 3 kunye ne-5).
I-UVA ayijongeli phantsi amandla eFotosynthetic yaMagqabi, kodwa iPhotoinhibits amagqabi kuMmandla
I-UVA ikhuthaza iMveliso yeSekondari yeMetabolite
UVAPromotes Secondary Metabolite Production
Ukuqukumbela
Ukongezwa kokukhanya kwe-LED ngemitha ye-UVA kwindawo elawulwayo kubangele indawo enkulu yamagqabi, ekhuthaza ukukhanya okungcono kunye nokwandisa kakhulu imveliso ye-biomass. Ukongeza, imitha ye-UVA ikwaphucule ukuqokelelwa kweemetabolites yesibini kwilettuce. Kumandla aphezulu e-UVA, izityalo zagxininiswa njengoko kubonisiwe yi-lipid peroxidation (okt, umxholo ophezulu we-MDA) kunye nomgangatho ophantsi wokuphumelela kwe-photosystem II photochemistry (F v / F m). Iziphumo zethu zibonisa ukuba impembelelo evuselelayo ye-UVA ekukhuleni kwe-lettuce ibonisa impendulo yokugcwalisa kwidosi ye-UVA.
Ukongezwa kwe-10, 20, kunye ne-30 µmol m-2 s-1 imitha ye-UVA ibangele ukunyuka kwesisindo sokudubula kwe-27% (UVA-10), 29% (UVA-20), kunye ne-15% (UVA-30), ngokulandelanayo, xa kuthelekiswa nolawulo. Indawo yeqabunga inyuke nge-31%, i-32%, kunye ne-14% kwi-UVA-10, i-UVA-20, kunye ne-UVA-30 yonyango, ngokulandelanayo (umzobo 2; iThebhile 2). Ukongeza, ukusasazeka kwemitha ye-UVA kukwavuselele inani lamagqabi (11% -18%). Indawo yeqabunga elithile, umlinganiselo wokudubula/ingcambu, kunye nomxholo wobunzima bokudubula awuchaphazelekanga yi-UVA (Itheyibhile 2).
Le yitumato etyalwe kunye nokukhanya kwesityalo sethu seG550 esineendlela ezine. Ubungakanani bentente yesityalo yi-1.2x1.2m
