Yog tias koj nyuam qhuav pib tshawb txog lub ntiaj teb teeb pom kev zoo hauv lub ntiaj teb, thiab koj tsis yog tus kws tshawb fawb txog kev cog qoob loo lossis cov kws paub txog teeb pom kev zoo, koj yuav pom cov ntsiab lus ntawm cov lus luv luv yuav nyuaj me ntsis.Yog li cia peb pib.Vim tias muaj ntau tus neeg txawj Youtubers tuaj yeem taug kev peb hla ob peb teev ntawm cov yeeb yaj kiab hauv tsawg dua 2 feeb.Cia saib seb peb tuaj yeem ua li cas rau cov teeb pom kev zoo nkauj.
Cia peb pib nrog PAR.PAR yog photosynthetic active hluav taws xob.PAR lub teeb yog lub wavelengths ntawm lub teeb nyob rau hauv qhov pom ntau yam ntawm 400 mus rau 700 nanometers (nm) uas tsav photosynthesis.PAR yog ib tug ntau siv (thiab feem ntau misused) lo lus hais txog horticulture teeb pom kev zoo.PAR tsis yog qhov ntsuas lossis "metric" zoo li ko taw, ntiv tes lossis kilos.Hloov chaw, nws txhais cov hom teeb uas xav tau los txhawb nqa photosynthesis.
PPF Stands rau photosynthetic photon flux, thiab nws ntsuas hauv umol / s.Nws hais txog cov photons emission los ntawm lub fixture ntawm ib tug thib ob.PPF tau txiav txim siab thaum lub sijhawm tsim khoom thiab tsim khoom.PPF tsuas yog ntsuas tau hauv ib lub cuab yeej tshwj xeeb hu ua Integrated Sphere.
Lwm lo lus uas koj hnov ntau zaus-PPFD.PPFD stands rau photosynthetic photon flux ceev.PPFD yog ntsuas ntau npaum li cas photons tiag tiag tsaws ntawm lub canopy, nrog umol ib ob ib square meter.PPFD tuaj yeem ntsuas los ntawm lub sensor hauv thaj teb thiab simulated los ntawm software.PPFD suav nrog ntau yam uas tsis yog qhov khoom siv, suav nrog qhov siab qhov siab thiab qhov cuam tshuam ntawm qhov chaw.
Peb cov lus nug tseem ceeb uas koj yuav tsum tau saib kom tau teb thaum tshawb fawb txog kev teeb pom kev zoo nkauj yog:
Ntau npaum li cas PAR lub fixture tsim (tseem raws li Photosynthetic Photon Flux).
Ntau npaum li cas instantaneous PAR los ntawm lub fixture yog muaj rau cov nroj tsuag (tseem raws li Photosynthetic Photon Flux Density).
Lub zog npaum li cas yog siv los ntawm kev sib tw los ua kom PAR muaj rau koj cov nroj tsuag ( ntsuas raws li Photon Efficiency).
Txhawm rau nqis peev hauv cov teeb pom kev zoo horticulture kom ua tau raws li koj txoj kev cog qoob loo thiab kev lag luam, koj yuav tsum paub txog PPF, PPFD, thiab photon efficiency kom paub txog kev txiav txim siab yuav khoom.Txawm li cas los xij, peb qhov kev ntsuas no yuav tsum tsis txhob siv los ua ib qho kev hloov pauv rau kev txiav txim siab yuav khoom.Muaj ob peb lwm qhov sib txawv xws li daim foos thiab coefficient of utilization (CU) uas yuav tsum tau xav txog thiab.
