Ake sikhulume ngendima ye-LED plant light spectrum - i-UVA, ukukhanya okuluhlaza okwesibhakabhaka, okumhlophe okubomvu, nokukhanya okubomvu.
Okulandelayo yizifundo ezimbili ze-spectrum ezintsha uma kuqhathaniswa, enye iwuhlobo olusha lokutshalwa kwe-basil, kanti enye iwuchungechunge lokutshalwa kwe-ulethisi. Uma unentshisekelo, ungabheka emaphepheni abo.
Sinezibani ezifanayo ngokuyisisekelo nalezi zibuko ezimbili. Uma sishintsha ubude beza beza be-LED obufanele, bangacishe bafane ncamashi.
Ngizoqhathanisa lezi zibukeli ezimbili ne-spectrum enobuntu (echazwe kamuva) ukuze ngibone umehluko. Izitshalo ezitshalwayo nazo ziyi-lettuce ne-basil.
Ake sikhulume nge-spectrum yokutshala i-basil kuqala

Lolu ucwaningo lwaseBrithani. Isiphetho esikhulu ukuthi ukukhanya okuluhlaza okungu-435nm kunenzuzo enkulu ekukhuleni kwezitshalo kunokukhanya okuluhlaza okungu-450nm!
Isilinganiso esibomvu-luhlaza okwesibhakabhaka se-spectrum esithombeni esingenhla singu-1:1.5 (1.4). Uma kubalwa ngokwamanje, empeleni kungu-1:1;
Ngikhathazeke kakhulu ngejika lokumunca ukukhanya kwe-basil emnandi, bheka uMdwebo 2.
Umfanekiso 2 Ijika elilula lokumunca le-basil elimnandi
Esithombeni, isengakwazi ukumunca ukukhanya okuningi ngaphansi kuka-400nm. Nginethuba lokwenza ucwaningo ngamalambu angu-340nm. Amalambu angu-340nm abiza kakhulu.
Ngokwejika lokumunca ukukhanya kwe-basil, ingabe lokhu kuzoba ngcono kune-spectrum ye-435nm: 663nm?
I-spectrum yokutshala ulethisi

Lolu ucwaningo lwesiShayina. Isiphetho esiyinhloko ukuthi esikhathini esithile, ukukhanya okwandayo kwe-UVA kungathuthukisa kakhulu isivuno kanye nekhwalithi yezitshalo zikalethisi.

Le spectrum ilingana ne-F89 spectrum yethu, enomehluko othile engxenyeni ye-UVA.
Kuzoba nezinye izibukeli ezi-2 ezibamba iqhaza ekuhlolweni kokulawula, zombili ezizongeza ukukhanya okunobuntu, okungukuthi, ubungane kubantu, okungenani ungabona ngokucacile. Njengoba sishilo, izici ezi-5 ezinkulu zezibani zezitshalo:
Futhi iHorti Guru, uhlelo lokulawula ukukhanya kwezitshalo.
I-Ultraviolet A (UVA) inobude begagasi obungu-320-400nm futhi ihlanganisa cishe u-3% wamaphoton adlula emkhathini womhlaba ekukhanyeni kwelanga okungokwemvelo. Ukukhanya kwe-UVA kwezitshalo akuyilimazi i-DNA
I-UV ikhonjiswe ukuthi yenyusa amanani e-THC, CBD, kanye nokukhiqizwa kwe-terpene kwezitshalo ze-cannabis
I-UVA isanyusa ukukhiqizwa kwama-metabolites esibili njenge-THC, i-CBD, i-terpenes nama-flavonoids kodwa ngaphandle kwemiphumela emibi yokukhanya kwe-UVB.
Imisebe ye-UVA izuzisa isivuno kanye nekhwalithi yolethisi wasendlini

Ushukela oncibilikayo namaprotheni
Okuqukethwe kwe-phenolic ne-flavonoid
Okuqukethwe kwe-Anthocyanin
Okuqukethwe kwe-Malondialdehyde (MDA).
Okuqukethwe kwe-ascorbic acid
Amaqabunga akhule ngaphansi kwe-UVA abonise okuqukethwe okuphezulu kwe-anthocyanin
I-UVA ikhulise umsebenzi we-SOD ne-CAT
I-UVA ingakhuphula ukukhiqizwa kwe-biomass
Ukwengezwa kwe-UVA endaweni elawulwayo akugcini nje ngokukhuthaza ukukhiqizwa kwe-biomass (Amathebula 2 no-4), kodwa futhi kwathuthukisa ikhwalithi yokudla okunomsoco kalethisi (Amathebula 3 kanye ne-5). ）
Lapha, sibonisa ukuthi ukwengeza i-UVA endaweni elawulwayo akukhuthazi nje kuphela ukukhiqizwa kwe-biomassproduction (Amathebula 2 no-4), kodwa futhi kuthuthukisa ikhwalithi yokudla okunomsoco we-lettuce (Amathebula 3 kanye no-5).
I-UVA Ayiwehlisi Umthamo Wezithombe Zeqabunga, Kodwa I-Photoinhibits Amaqabunga Aphezulu
I-UVA Ikhuthaza Ukukhiqizwa Kwe-Metabolite Yesibili
UVAPromotes Secondary Metabolite Production
Isiphetho
Ukwengeza ukukhanya kwe-LED ngemisebe ye-UVA endaweni elawulwayo kubangele indawo enkulu yamahlamvu, okukhuthaze ukunqamuka kokukhanya okungcono futhi kwandise kakhulu ukukhiqizwa kwe-biomass. Ngaphezu kwalokho, imisebe ye-UVA iphinde yathuthukisa ukuqoqwa kwama-metabolite esibili ku-lettuce. Emazingeni aphezulu e-UVA, izitshalo zagcizelelwa njengoba kuboniswa i-lipid peroxidation (okungukuthi, okuqukethwe okuphezulu kwe-MDA) kanye nokusebenza kahle kwe-quantum ephezulu ye-photosystem II photochemistry (F v / F m). Imiphumela yethu ikhombisa ukuthi umthelela ovuselelayo we-UVA ekukhuleni kukalethisi ubonisa impendulo yokugcwalisa umthamo we-UVA.
Ukwengezwa kwemisebe engu-10, 20, kanye no-30 µmol m-2 s-1 UVA kubangele ukwanda kwesisindo sokudubula esingu-27% (UVA-10), 29% (UVA-20), no-15% (UVA-30), ngokulandelanayo. , uma kuqhathaniswa nokulawula. Indawo yeqabunga inyuke ngo-31%, 32%, no-14% ekwelapheni kwe-UVA-10, UVA-20, kanye ne-UVA-30, ngokulandelana (Fig. 2; Ithebula 2). Ngaphezu kwalokho, imisebe ye-UVA iphinde yavuselela inombolo yamaqabunga (11% -18%). Indawo yeqabunga ethize, isilinganiso sehlumela/izimpande, nokuqukethwe kwenqwaba yehlumela akuzange kuthinteke i-UVA (Ithebula 2).
Lona utamatisi otshalwe ngokukhanya kwethu kwezitshalo ezineziteshi ezine ze-G550. Usayizi wetende lesitshalo ngu-1.2x1.2m
