Ziziphi iintsingiselo ze-Acronyms PAR, PPF kunye nePPFD?

Ukuba usandula ukuqalisa ukuhlola umhlaba wokukhanya kwe-horticultural, kwaye awuyena usosayensi wezityalo onamava okanye ingcali yokukhanyisa, unokufumana imimiselo ye-acronyms ibe yinto enzima.Ke masiqale.Njengoko uninzi lwabasebenzisi be-Youtuber abanetalente banokusihambisa kwiiyure ezininzi zeemuvi ngaphantsi kwemizuzu emi-2.Makhe sibone ukuba singenza ntoni na kwizibane zezityalo.

Masiqale ngePAR.I-PAR yimitha ye-photosynthetic esebenzayo.Ukukhanya kwe-PAR kubude bamaza okukhanya ngaphakathi koluhlu olubonakalayo lwe-400 ukuya kwi-700 nanometers (nm) eqhuba i-photosynthesis.PAR ligama elisetyenziswa kakhulu (kwaye lidla ngokusetyenziswa kakubi) elinxulumene nokukhanya kwe-horticulture.I-PAR AYISIYO imilinganiselo okanye “imetric” efana neenyawo, i-intshi okanye iikhilos.Kunoko, ichaza uhlobo lokukhanya olufunekayo ukuxhasa iphotosynthesis.

I-PPF Imele ifoton yefoton flux, kwaye ilinganiswa nge-mol/s.Ibhekisa kwiifotoni ezikhutshwa kwifixture nangawuphi na umzuzwana.I-PPF imiselwa ngexesha isayilwa kwaye yenziwe.I-PPF inokulinganiswa kuphela kwisixhobo esikhethekileyo esibizwa ngokuba yi-Integrated Sphere.

Elinye igama oliva rhoqo-PPFD.I-PPFD imele i-photosynthetic photon flux density.I-PPFD ilinganisa ukuba zingakanani iifotoni ezihlala kwi-canopy, kunye ne-mol ngesekondi nganye yesikwere semitha.I-PPFD inokulinganiswa ngenzwa kwintsimi kwaye ifaniswe yi-software.I-PPFD ibandakanya izinto ezininzi ngaphandle kokulungiswa, kubandakanya ukuphakama kokuphakama kunye nokubonakala komphezulu.

Imibuzo emithathu ebalulekileyo ekufuneka ujonge ukuba iphendulwe xa uphanda ngeenkqubo zokukhanyisa izitiya zezi:
Ingakanani i-PAR eveliswa yi-fixture (ilinganiswa njenge-photosynthetic Photon Flux).
Ingakanani i-PAR ekhawulezileyo esuka kwisihlunu ekhoyo kwizityalo (ilinganiswa njengePhotosynthetic Photon Flux Density).
Angakanani amandla asetyenziswa luzinziso ukwenza i-PAR ifumaneke kwizityalo zakho (zilinganiswe njenge-Photon Efficiency).

Ukuze utyale imali kwindlela efanelekileyo yokukhanyisa i-horticulture ukuhlangabezana neenjongo zakho zokulima kunye nezoshishino, kufuneka uyazi i-PPF, i-PPFD, kunye nokusebenza kakuhle kweefoton ukwenza izigqibo zokuthenga unolwazi.Nangona kunjalo, ezi metrics zintathu akufuneki zisetyenziswe njengezinto eziguquguqukayo kuphela ukuseka izigqibo zokuthenga.Kukho ezinye izinto ezahlukeneyo ezifana nefom factor kunye ne-coefficient of utilization (CU) ekufuneka iqwalaselwe ngokunjalo.
