Uma usanda kuqala ukuhlola umhlaba wokukhanyisa kwe-horticultural, futhi ungeyena usosayensi wezitshalo osemnkantshubomvu noma uchwepheshe wokukhanyisa, ungase uthole imigomo yama-acronyms ibe namandla.Ngakho-ke asiqale.Njengoba ama-Youtubers amaningi anekhono angasidlulisa emahoreni ambalwa wamamuvi ngaphansi kwemizuzu emi-2.Ake sibone ukuthi yini esingayenza ngokukhanyisa kwe-horticultural.
Ake siqale nge-PAR.I-PAR iyimisebe esebenzayo ye-photosynthetic.Ukukhanya kwe-PAR ubude begagasi bokukhanya ngaphakathi kwebanga elibonakalayo le-400 kuya ku-700 nanometers (nm) elishayela i-photosynthesis.PAR iyigama elisetshenziswa kakhulu (futhi elivame ukusetshenziswa kabi) elihlobene nokukhanyisa kwe-horticulture.I-PAR AYISIYO isikali noma “imethrikhi” njengezinyawo, amayintshi noma amakhilogremu.Kunalokho, ichaza uhlobo lokukhanya oludingekayo ukuze kusekelwe i-photosynthesis.
I-PPF Imele i-photosynthetic photon flux, futhi ikalwa nge-mol/s.Kubhekiselwa kuma-photon akhishwa endaweni noma yimuphi umzuzwana othile.I-PPF inqunywa ngesikhathi isakhiwo siklanywa futhi senziwa.I-PPF ingakalwa kuphela ngesisetshenziswa esikhethekile esibizwa ngokuthi I-Integrated Sphere.
Elinye igama olizwa njalo-i-PPFD.I-PPFD imele i-photosynthetic photon flux density.I-PPFD ikala ukuthi angakanani ama-photon ahlala ku-canopy, nge-mol ngesekhondi imitha yesikwele.I-PPFD ingakalwa yisinzwa esisendle futhi ifaniswe yisoftware.I-PPFD ihlanganisa izinto eziningi ngaphandle kwe-fixture, okuhlanganisa ukuphakama okukhwezayo nokubonakala kwendawo.
Imibuzo emithathu ebalulekile okufanele ubheke ukuthi iphendulwe lapho ucwaninga amasistimu okukhanyisa ama-horticulture yilena:
Ingakanani i-PAR ekhiqizwa yi-fixture (ikalwa njenge-Photosynthetic Photon Flux).
Ingakanani i-PAR esheshayo evela ku-fixture etholakala ezitshalweni (ekalwa njenge-Photosynthetic Photon Flux Density).
Angakanani amandla asetshenziswa yi-fixture ukwenza i-PAR itholakale ezitshalweni zakho (kukalwa njengokuthi I-Photon Efficiency).
Ukuze utshale imali ohlelweni olufanele lokukhanyisa i-horticulture ukuze uhlangabezane nezinjongo zakho zokutshala nebhizinisi, udinga ukwazi i-PPF, i-PPFD, nokusebenza kahle kwe-photon ukuze wenze izinqumo zokuthenga unolwazi.Kodwa-ke, lawa mamethrikhi amathathu akufanele asetshenziswe njengokuhluka okukodwa ukuze kusekelwe izinqumo zokuthenga.Kukhona okunye okuguquguqukayo okuningana okufana ne-form factor kanye ne-coefficient of utilization (CU) okudingeka kucatshangelwe futhi.
