LED teeb pom kev zooQhov tseem ceeb hauv Cannabis Loj hlob
Kev ua kom zoo tshaj plaws ntawm kev cog qoob loo yog qhov tseem ceeb tshaj plaws rau cov kws tshawb fawb thiab cov neeg cog qoob loo vim qhov kev loj hlob raug cai thiab kev lag luam ntawm kev lag luam hemp (Cannabis sativa L.) rau kev lag luam thiab kev siv tshuaj kho mob. Lub teeb yog ib qho tseem ceeb ntawm ib puag ncig kev hloov pauv uas cuam tshuam rau kev loj hlob ntawm cov nroj tsuag. Cov txiaj ntsig tseem ceeb ntawm kev siv LED (Light Emitting Diode) teeb pom kev zoo tshaj li cov pa siab siab - siab sodium (HPS) teeb nyob rau hauv tsev hemp loj hlob tau hais txog los ntawm kev tshawb fawb tsis ntev los no, xws li ib qho ua los ntawm Zhang Xiaoyan li al. (2023). Qhov tseem ceeb ntawmLED teeb pom kev zooHauv kev txhawb nqa kev lag luam hemp txoj kev loj hlob, kev loj hlob, thiab photosynthetic efficiency yog them rau hauv txoj kev tshawb no.
Txheej txheem cej luam
Cannabis nrog tsawg dua 0.3% THC raug xa mus rau kev lag luam hemp. Nws yog khoom plig rau nws tsis yog -psychoactive cannabinoids, zoo li CBD thiab CBG, uas tau pom tias muaj peev xwm kho tau. Qhov xav tau rau txoj kev ua liaj ua teb sab hauv tsev tau loj hlob nrog rau qhov kev thov rau cov txiaj ntsig zoo. Artificial teeb pom kev zoo yog qhov tseem ceeb hauv cov kab ke no kom rov ua dua lub hnub ci ntuj thiab txhawb nqa cov nroj tsuag zoo tshaj plaws. Txawm hais tias HPS teeb tau siv dav hauv horticulture, LED thev naus laus zis tau dhau los ua qhov kev xaiv zoo dua vim tias nws tsis tshua muaj cua sov, spectrum tswj, thiab kev lag luam hluav taws xob.
Txhim kho txoj kev loj hlob ntawm Morphology
Nws tau raug pom tiasLED teeb pom kev zootxhim kho ntau tus yam ntxwv morphological hauv kev lag luam hemp. LED-cov nroj tsuag kho tau pom cov nplooj loj dua, cov qia tuab dua, cov pob ntau dua, txhim kho cov ceg, thiab cov cag ntev dua thaum piv rau HPS teeb. Cov yam ntxwv no muaj kev sib txuas zoo rau kev noj zaub mov kom zoo, kev ntes lub teeb, thiab lub zog ntawm cov qauv. Piv txwv li, LED-cov nroj tsuag cog muaj 21.23% nplooj nplooj ntau dua li HPS- cog cov nroj tsuag thoob plaws lub paj. Qhov no yog qhov tseem ceeb tshwj xeeb vim tias muaj peev xwm photosynthetic thiab biomass tso tawm muaj kev sib raug zoo nrog thaj tsam nplooj.
HPS teeb, ntawm qhov tod tes, txhawb cov nroj tsuag siab nrog ntev internodes, uas tuaj yeem ua rau cov qia tsis muaj zog thiab muaj feem ntau dua ntawm chaw nyob. Raws li qhov tshwm sim, LEDs pab tsim kom muaj kev ruaj khov thiab cog kev cog lus ntau dua, uas yog qhov zoo tagnrho rau kev loj hlob sab hauv tsev thaum chav tsis tshua muaj.
Txhim kho Photosynthetic Efficiency
Lub peev xwm ntawmLED teeb pom kev zootxhawm rau txhim kho photosynthetic efficiency yog ib qho ntawm nws cov txiaj ntsig zoo tshaj plaws. Zhang li al. txoj kev tshawb fawb pom tau hais tias cov nroj tsuag raug rau LED teeb muaj ntau dua net photosynthetic tus nqi (P n P n), stomatal conductance (G s G s), intercellular CO2 concentration (C i C i), thiab transpiration rate (T r T r). Thaum piv rau cov nroj tsuag nyob rau hauv HPS teeb, cov nqi no yog 8.48% rau 55.78% siab dua hauv LED- kho cov nroj tsuag.
Qhov kev txhim kho no tau piav qhia los ntawm LEDs 'adjustable lub teeb spectrum, uas tuaj yeem ua kom sib haum nrog lub ncov ntawm chlorophyll's photosynthetic absorption. Hauv particular, liab thiab xiav wavelengths paub tias ua tau zoo tsav photosynthesis. LEDs tso cai rau cov nroj tsuag siv lub teeb kom zoo dua los ntawm kev muab qhov sib npaug, uas ua rau cov pa roj carbon ntau ntxiv thiab kev loj hlob.
Txau ntawm Biomass
Txhua qhov kev ua liaj ua teb lub hom phiaj kawg yog txhawm rau txhim kho cov qoob loo thiab biomass. Thaum piv rau HPS,LED teeb pom kev zootsis tu ncua ua kom loj qhuav hnyav ntawm nplooj, stems, thiab keeb kwm. Piv txwv li, lub hauv paus qhuav qhov hnyav nyob rau hauv LED yog 45.05% ntau dua nyob rau hauv HPS thaum lub sij hawm flowering lub sij hawm. Qhov no qhia txog kev txhim kho hauv paus thiab kev faib cov peev txheej, ob qho tib si tseem ceeb rau kev noj zaub mov zoo thiab kev noj qab haus huv ntawm cov nroj tsuag.
Tsis tas li ntawd, THC cov ntsiab lus tsis txo qis vim qhov nce biomass nyob rau hauv LED teeb pom kev zoo. Raws li txoj kev tshawb fawb, tsis muaj qhov pom kev hloov pauv ntawm THC, CBD, lossis CBG ntawm ob lub teeb pom kev zoo, qhia tias LEDs tuaj yeem txhawb kev loj hlob yam tsis muaj kev txi cov tshuaj purity.
Zog txuag hluav taws xob thiab siv tau zoo
LEDs muabib tug xov tooj ntawm pab tau zoo rau sab hauv hemp zus tau tej cov uas mus tshaj cov nroj tsuag physiology. Muab piv rau HPS teeb, lawv siv tsawg zog, kav ntev dua, thiab tsim hluav taws xob tsawg. Vim li no, cov neeg tsim khoom tuaj yeem tso lub teeb kom ze rau ntawm cov canopy yam tsis muaj kev nyab xeeb ntawm nplooj ntoos hlawv lossis kub ntxhov. Nyob rau hauv txoj kev tshawb no, HPS teeb tau muab tso rau 100 cm deb ntawm cov nroj tsuag saum, thaum LEDs tau muab tso rau 50 cm deb. Lub teeb siv hluav taws xob ntau dua thiab ntau dua txawm tias lub teeb xa tawm tau lees paub los ntawm qhov ze ze.
Txhawm rau txhim kho cov nroj tsuag kom zoo dua qub, LEDs tuaj yeem hloov kho kom ua raws li lub sijhawm ntuj tsim thiab hloov spectrum thaum lub voj voog loj hlob. Nrog HPS thev naus laus zis, qhov kev tswj hwm qib no tsis tuaj yeem ua tau.
Hauv kev xaus
Los xaus,LED teeb pom kev zooyog ib kauj ruam loj rau pem hauv ntej rau kev lag luam hemp loj hlob hauv tsev. Nws yog qhov kev xaiv zoo dua li cov teeb pom kev zoo HPS vim nws lub peev xwm los txhim kho morphological nta, txhim kho photosynthetic efficiency, thiab nce biomass tsub zuj zuj. Kev siv cov thev naus laus zis LED tuaj yeem ua rau muaj txiaj ntsig zoo, ua haujlwm tau zoo, thiab kev loj hlob ruaj khov raws li cov hemp sector loj hlob. Txhawm rau txhawm rau txhawm rau txhim kho cov txiaj ntsig zoo thiab cannabinoid profiles, kev tshawb fawb yav tom ntej yuav tsum tau mloog zoo rau kev kho lub teeb pom kev zoo thiab kev siv zog rau qee hom hemp. Rau lub sijhawm tam sim no, nws pom tseeb tiasLED teeb pom kev zooyog yav tom ntej ntawm sab hauv hemp loj hlob, tsis tsuas yog hloov.
