Lub wavelength ntawm PAR tus nqi siv los ntawm cov teb chaws thoob plaws ntiaj teb los tshawb fawb cov nroj tsuag photosynthesis nyob rau hauv lub hnub ci hluav taws xob tsuas yog muab nyob rau hauv 400-700 nm ntau. Txawm hais tias muaj UV thiab FR ib feem bands, ntau LED cog teeb uas tshaj tawm tias yog tag nrho cov spectrum tseem siv PPFD los piav txog cov khoom spectral. Tus nqi ntawm micromoles ntawm 400 thiab 700 nm tsis tau hais vim PPFD tsis piav qhia txog hluav taws xob ntawm UV thiab FR. Qhov no tag nrho-spectrum cog teeb lub PPFD ntsuam xyuas tsis quav ntsej txog cov hluav taws xob spectral tam sim no. Tsis yog, cov neeg tsim khoom ntawm nominal full-spectrum cog teeb tsis paub txog qhov tsis raug me ntsis.
Lub thiaj li hu ua tag nrho-spectrum cog teeb undoubtedly nrhiav kom qhia cov spectrum ntau haiv neeg. Lo lus "tag nrho" tsis yog qhov tseeb. "Full" piav txog qhov dav spectrum ntawm wavelengths. Lub "tag nrho spectrum" yog txawv tam sim no. Qhov siab tshaj plaws txhais tau yog nyob nruab nrab ntawm 380 thiab 780 nm. Txij li thaum "tag nrho spectrum" tsis muaj lub ntsiab lus pom zoo, txhua tus muaj kev ywj pheej los muab lawv tus kheej. Raws li qhov tshwm sim, "tag nrho spectrum" muaj ntau lub ntsiab lus sib txawv.
Tsis muaj txoj cai tam sim no tau muab "tag nrho spectrum" txhais.
Peb xav tias lub tswv yim ntawm tag nrho cov spectrum, uas piav txog daim ntawv spectral, yog hazy. Lub spectrum photosynthetic efficiency muaj nuj nqi raws li ntau yam, tsis yog nws cov nqi ntau, yog dab tsi txiav txim lub wavelength ntau yam ntawm cov nroj tsuag teeb. Tag nrho cov spectrum tsis yog ib txwm sib npaug rau cov muaj zog photosynthetic tus nqi thiab cog. Lub hom phiaj tom qab propagating tag nrho spectrum yog siv cov kab lus "tag nrho" los ua kom muaj kev cuam tshuam ntawm cov nroj tsuag teeb pom kev zoo, uas yuav ua rau muaj kev xav tsis zoo ntawm cov neeg siv cov teeb pom kev zoo.
Lub teeb npaum li cas thiab zoo ua ke los ua cov nroj tsuag lub teeb spectrum. Txoj kev siv los cog ib tsob ntoo tshwj xeeb tseem cuam tshuam rau lub wavelength ntau ntawm cov nroj tsuag lub teeb spectrum. Lub npe ntawm tus qauv spectral yog tsim los ntawm cov txheej txheem cog es tsis yog cog hauv qab spectrum.
Muaj ib qho spectroscopic hypothesis uas cuam tshuam rau cov nroj tsuag teeb tsim uas exaggerates lub spectrum cog kev cuam tshuam. Lub spectrum tsuas yog qhov tsim nyog tshaj plaws, tsis yog qhov zoo tshaj plaws. Nov yog qhov peb pom tej yam.
VANQ tau categorized cov spectral cov ntaub ntawv ntawm cov nroj tsuag teeb nyob rau hauv thiaj li yuav tshawb xyuas thiab xa cov spectrum, thiab peb tau txhais ob daim ntawv spectral:
1. Nruam spectrum: Lub zog hluav taws xob kho qhov muag tsis zoo li yog xoom thoob plaws hauv qhov teev ntau ntawm wavelengths.
2. Discontinuous spectrum: Lub hwj chim hluav taws xob kho qhov muag yog xoom thoob plaws hauv qhov teev wavelength.
(Ceeb Toom: Lub hwj chim hluav taws xob hluav taws xob hluav taws xob tsis tas yuav tsum yog xoom. Nws paub tias qhov txheeb ze hluav taws xob hluav taws xob nce mus txog xoom thaum nws tsawg dua lossis sib npaug rau 0.002. Raws li lub ntsiab lus ntawm xoom , photosynthesis thiab lub teeb daim ntawv tswj tsis cuam tshuam los ntawm tus lej no.)
Rau lub hom phiaj ntawm kev faib spectral morphology rau txoj kev kawm ntawm cov nroj tsuag teeb spectroscopy technology, cov ntsiab lus ntawm nruam spectrum thiab discontinuous spectrum yog nthuav. Kev txheeb xyuas cov ntaub ntawv spectrum siv tib lub spectral morphology yog kev tshawb fawb ntau dua. Cov teeb pom kev tseem ceeb ntawm cov nroj tsuag muaj xws li QE, PPF, YPF, PPFD, thiab lwm yam. Yuav kom nkag siab, yuav tsum muaj kev sib piv ntawm ob daim ntawv spectral no.
Nruab nrab ntawm cov teeb pom kev zoo nrog cov spectrum txuas ntxiv thiab cov uas muaj qhov tsis sib xws, tsis muaj qhov sib txawv meej. Feem ntau hais lus, ib qho raug tsim tsis tu ncua spectrum muaj kev cog qoob loo zoo dua li cov spectrum txuas ntxiv, tab sis nws cov nqi ntau lawm yog siab dua.
Qhov twb tau lees paub tag nrho-spectrum cog teeb yuav yog ib qho spectrum tsis tu ncua lossis tsis txuas ntxiv spectrum, raws li peb categorization ntawm spectral morphology.
Cov nroj tsuag teeb lub spectral daim ntawv yog muab faib mus rau hauv ib tug tas mus li spectrum thiab ib tug tsis tu ncua spectrum, thiab kev sib txuas lus thiab kev qhia yog intuitive thiab meej, uas yog pab tau rau kev sib txuas lus thiab cov khoom txhawb nqa thiab ua rau nws yooj yim rau cov nroj tsuag cov neeg siv kom nkag siab.
Cog teeb 'spectrum technology yog complex thiab yuav tsum tau piav qhia siv cov ntsiab lus yooj yim. Cog teeb 'spectrum designs yuav tsum tsis txhob leaning ntau dhau ntawm fantasy thiab deceiving cov neeg muas zaub.
