Cia peb tham txog lub luag haujlwm ntawm LED cog lub teeb spectrum - UVA, xiav-dawb lub teeb, liab-dawb lub teeb, thiab deb-liab teeb
Cov nram qab no yog ob qhov kev tshawb fawb tshiab spectrum, ib qho yog ib qho tshiab rau kev cog qoob loo basil, thiab lwm qhov yog spectrum rau kev cog qoob loo. Yog tias koj txaus siab, koj tuaj yeem xa mus rau lawv cov ntaub ntawv.
Peb muaj teeb pom kev zoo ib yam li ob lub spectrum no. Yog tias peb hloov qhov cuam tshuam LED wavelength, lawv tuaj yeem yuav luag zoo ib yam.
Kuv yuav muab piv rau ob lub spectrum no nrog cov tib neeg spectrum ntau dua (pib tom qab) kom pom qhov txawv. Cov qoob loo cog kuj yog lettuce thiab basil.
Cia peb tham txog basil cog spectrum ua ntej

Qhov no yog ib qho kev tshawb fawb British. Lub ntsiab lus xaus yog tias 435nm xiav lub teeb muaj txiaj ntsig zoo rau cov nroj tsuag loj hlob ntau dua li 450nm xiav lub teeb!
Qhov sib piv liab-xiav ntawm cov spectrum hauv daim duab saum toj no yog 1: 1.5 (1.4). Yog xam raws li qhov tam sim no, nws yog 1: 1;
Kuv txhawj xeeb ntau ntxiv txog lub teeb pom kev nkhaus ntawm qab zib basil, saib daim duab 2.
Daim duab 2 Lub teeb absorption nkhaus ntawm qab zib basil
Hauv daim duab, nws tseem tuaj yeem nqus tau ntau lub teeb hauv qab 400nm. Kuv muaj sijhawm los ua qhov kev sim nrog 340nm teeb. 340nm teeb yog kim heev.
Raws li lub teeb absorption nkhaus ntawm basil, qhov no puas yuav zoo dua li spectrum ntawm 435nm: 663nm?
Lettuce cog spectrum

Nov yog kev kawm suav. Lub ntsiab lus xaus yog tias nyob rau lub sijhawm tshwj xeeb, ua kom UVA lub teeb tuaj yeem txhim kho cov txiaj ntsig zoo thiab cov qoob loo zoo ntawm lettuce.

Qhov spectrum no sib npaug rau peb cov F89 spectrum, nrog qee qhov sib txawv ntawm UVA.
Yuav muaj 2 ntau qhov kev koom tes hauv kev ntsuas kev tswj hwm, ob qho tib si yuav ntxiv cov teeb pom kev zoo rau tib neeg, uas yog, tus phooj ywg zoo rau tib neeg, tsawg kawg koj tuaj yeem pom meej. Raws li peb tau hais, 5 lub ntsiab tseem ceeb ntawm cov teeb pom kev zoo:
Thiab Horti Guru, cog lub teeb tswj qhov system.
Ultraviolet A (UVA) muaj lub wavelength ntawm 320-400nm thiab suav txog li 3% ntawm photons hla lub ntiaj teb huab cua hauv ntuj hnub ci. UVA teeb rau cov nroj tsuag tsis puas DNA
UV tau pom tias nce qhov nyiaj ntawm THC, CBD, thiab terpene ntau lawm incannabis nroj tsuag
UVA tseem ua rau muaj kev tsim cov metabolites theem nrab xws li THC, CBD, terpenesand flavonoids tab sis tsis muaj qhov tsis zoo ntawm UVB lub teeb.
UVA hluav taws xob muaj txiaj ntsig zoo rau kev tawm los thiab zoo ntawm cov lettuce sab hauv

Soluble qab zib thiab cov ntsiab lus protein
Cov ntsiab lus phenolic thiab flavonoid
Cov ntsiab lus anthocyanin
Malondialdehyde (MDA) cov ntsiab lus
Cov ntsiab lus ntawm ascorbic acid
Nplooj hlob nyob rau hauv UVA pom cov ntsiab lus anthocyanin ntau dua
UVA nce kev ua haujlwm ntawm SOD thiab CAT
UVA tuaj yeem nce biomass ntau lawm
Ntxiv ntawm UVA nyob rau hauv ib puag ncig tswj tsis tau tsuas yog txhawb nqa biomass ntau lawm (Table 2 thiab 4), tab sis kuj txhim kho cov zaub mov zoo ntawm lettuce (Tables 3 thiab 5). )
Ntawm no, peb qhia tau hais tias ntxiv UVA nyob rau hauv ib cheeb tsam tswj tsis tau tsuas yog nkoos biomassproduction (Tables 2 thiab 4), tab sis kuj txhim kho cov khoom noj khoom haus zoo ntawm lettuce (Tables 3 thiab 5).
UVA tsis txo qis nplooj Photosynthetic muaj peev xwm, tab sis Photoinhibits nplooj ntawm HighIntensity

Ntxiv lub teeb ci LED nrog UVA hluav taws xob nyob rau hauv ib puag ncig tswj tau ua rau thaj chaw nplooj loj dua, uas txhawb nqa lub teeb pom kev zoo dua thiab ua kom muaj biomass ntau ntxiv. Tsis tas li ntawd, UVA hluav taws xob kuj tau txhim kho qhov sib txuam ntawm cov metabolites theem nrab hauv lettuce. Thaum siab UVA kev siv zog, cov nroj tsuag tau ntxhov siab raws li qhia los ntawm lipid peroxidation (piv txwv li, cov ntsiab lus MDA siab dua) thiab qis dua qhov siab tshaj plaws quantum efficiency ntawm photosystem II photochemistry (F v / F m). Peb cov txiaj ntsig tau qhia tias cov txiaj ntsig zoo ntawm UVA ntawm kev loj hlob lettuce nthuav tawm cov lus teb saturation rau UVA koob tshuaj.
Ntxiv ntawm 10, 20, thiab 30 µmol m-2 s-1 UVA hluav taws xob ua rau nce qhov hnyav ntawm 27% (UVA-10), 29% (UVA-20), thiab 15% (UVA-30), feem, piv rau kev tswj. Nplooj nplooj nce 31%, 32%, thiab 14% hauv kev kho UVA-10, UVA-20, thiab UVA-30, raws li (Fig. 2; Table 2). Tsis tas li ntawd, UVA hluav taws xob kuj txhawb nqa cov nplooj ntawv (11% -18%). Cov nplooj ntoo tshwj xeeb, qhov sib piv / cov cag, thiab tua cov ntsiab lus tsis cuam tshuam los ntawm UVA (Table 2).
Qhov no yog txiv lws suav cog nrog peb G550 plaub-channel cog teeb. Lub tsev pheeb suab cog yog 1.2x1.2m
