Txhim kho Suav Cabbage Loj hlob thiab khoom noj khoom haus zoo nrog OptimizedLED Lub Teeb Spectra
Lub teeb yog ib qho tseem ceeb hauv kev loj hlob ntawm cov nroj tsuag, cuam tshuam tsis tau tsuas yog photosynthesis tab sis kuj metabolic txoj kev uas txiav txim siab qoob loo thiab zoo. Kev tshawb fawb tsis ntev los no ua los ntawm Liu et al. (2024) muab cov pov thawj txaus ntseeg txog kev sib xyaw ua ke ntawm LED teeb pom kev zoo tuaj yeem txhim kho kev loj hlob, kev noj zaub mov zoo, thiab nitrogen metabolism ntawm Suav cabbage (Brassica rov), muab cov kev pom muaj txiaj ntsig zoo rau kev coj noj coj ua niaj hnub no.
Kev Tshawb Fawb Txog Kev Tshawb Fawb
Txoj kev tshawb no tau tshuaj xyuas cov teebmeem ntawm tsibLED teebKev kho mob ntawm kev loj hlob thiab physiological teb ntawm Suav cabbage:
W: Dawb lub teeb (tswj)
RB: Liab:Blue=3:1
RBG: Liab: Xiav: Ntsuab=3: 1: 1
RBP: Red:Blue:Violet=3:1:1
RBF: Red:Blue:Far-red=3:1:1
Cov nroj tsuag tau loj hlob nyob rau hauv ib lub teeb sib xws ntawm 150 μmol·m⁻²·s⁻¹ nrog 14/10-teev lub teeb / tsaus voj voog. Tom qab 30 hnub, cov kws tshawb fawb tau ntsuas qhov morphological zoo, cov ntsiab lus xim, cov khoom noj khoom haus zoo, nitrogen metabolism enzyme kev ua ub no, thiab muaj feem cuam tshuam cov noob qhia qib.
Cov kev tshawb pom tseem ceeb
1. Txhim khu kev loj hlob thiab biomass tsub zuj zuj
CovKev kho mob RBP(liab: xiav: violet) qhia tau hais tias muaj kev ua tau zoo tshaj plaws nyob rau ntau qhov kev loj hlob:
Nroj qhov siab: Nce 7.8% piv rau kev tswj hwm
Cev kab: Txhim kho los ntawm 26.4%
Aboveground tshiab loj: 67.8% siab dua tswj
Underground tshiab pawg: 200.7% nce kev tswj hwm
Cov txiaj ntsig no qhia tau hais tias ntxiv lub teeb violet rau cov pa liab -xiav spectrum tseem ceeb txhawb kev loj hlob thiab kev loj hlob hauv paus.
2. Txhim kho Photosynthetic Pigment Cov ntsiab lus
Kev kho RBP tseem ceeb txhawb nqa photosynthetic efficiency:
Chlorophyll ib: 111.7% siab dua tswj
Tag nrho chlorophyll: 111.9% nce
Carotenoids: 47.3% kev txhim kho
Qhov kev txhim kho tseem ceeb hauv cov ntsiab lus pigment qhia zoo duateebntes thiab siv hauv RBP spectrum.
3. Khoom noj khoom haus zoo tshaj
Kev kho RBP tau txais txiaj ntsig zoo tshaj plaws tag nrho cov khoom noj khoom haus profile:
Soluble protein: 16.4% siab dua tswj
Vitamin C: 38.1% nce
Soluble qab zib: 63.3% kev txhim kho
Nitrate cov ntsiab lus: Qhov tseem ceeb nce siab, qhia txog kev txhim kho nitrogen uptake
Nitrite qib: Txo qis piv rau kev tswj
Cov kev txhim kho no muaj txiaj ntsig tshwj xeeb rau cov neeg cog khoom lag luam uas tsom mus rau cov khw noj zaub zoo.
4. Txhim kho Nitrogen Metabolism
Txoj kev kho RBP tau qhib txoj hauv kev tseem ceeb nitrogen assimilation:
Kev ua haujlwm ntawm nitrate reductase (NR).: 244.8% siab dua tswj
Kev ua haujlwm ntawm nitrite reductase (NiR).: Tau nce ntxiv
Glutamate synthase (GOGAT): Kev ua haujlwm siab thib ob tom qab kev kho mob RB
Gene qhia: Upregulation ntawm NR, NiR, GS, thiab GDH noob
Qhov kev ua kom zoo ntawm nitrogen metabolism enzymes thiab noob piav qhia txog kev txhim kho kev loj hlob thiab kev ua tau zoo raws li kev kho RBP.
Kev siv tswv yim rau cov lag luam loj hlob
Txoj kev tshawb no qhia tau hais tias ntxiv liab -xiavLED tsom teebnrog violet lub teeb (RBP=3: 1: 1) tsim lub teeb pom kev zoo rau Suav cabbage ntau lawm, ua rau:
Kev loj hlob sai dua thiab ntau dua yields
Txhim kho cov khoom noj khoom haus zoo thiab cov nqi lag luam
Txhim kho nitrogen siv efficiency
Kev loj hlob zoo hauv paus thiab cog vigor
Pom zoo LED Solution
Rau cov neeg cog qoob loo nrhiav los siv cov kev tshawb fawb no,Benwei Teeb pom kev zoomuaj cov programmable siab heevLED systemsuas tuaj yeem xa qhov tseeb RBP (3: 1: 1) spectrum pov thawj zoo hauv txoj kev tshawb no. Lawv lub zog-ntau npaum, puv - spectrum kev daws teeb meem yog qhov zoo tagnrho rau kev ua liaj ua teb ntsug, tsev cog khoom, thiab kev ua liaj ua teb sab hauv.

Qhov kev tshawb fawb no qhia txog qhov tseem ceeb ntawm kev tswj lub teeb pom kev zoo hauv kev ua liaj ua teb niaj hnub no. Los ntawm kev siv cov txheej txheem teeb pom kev zoo ntawm LED, xws li RBP kev sib xyaw ua ke pom hauv qhov kev tshawb fawb no, cov neeg cog qoob loo tuaj yeem ua tiav qhov kev txhim kho tseem ceeb ntawm ob qho tib si kom muaj nuj nqis thiab zoo ntawm Suav cabbage ntau lawm thaum ua kom muaj txiaj ntsig zoo.
