Kodi Ma Acronyms PAR, PPF Ndi PPFD Amatanthauza Chiyani?

Ngati mwangoyamba kumene kuyang'ana dziko la kuwala kwa zomera, ndipo simuli katswiri wa sayansi ya zomera kapena katswiri wowunikira, mukhoza kupeza kuti mawu ofupikitsa amakhala ovuta kwambiri.Chifukwa chake tiyeni tiyambire.Popeza ma Youtuber ambiri aluso amatha kutidutsa makanema angapo osakwana mphindi ziwiri.Tiyeni tiwone zomwe tingachite pakuwunikira kwamaluwa.

Tiyeni tiyambe ndi PAR.PAR ndi cheza cha photosynthetic yogwira ntchito.Kuwala kwa PAR ndi kutalika kwa kuwala kwapakati pa 400 mpaka 700 nanometers (nm) yomwe imayendetsa photosynthesis.PAR ndi mawu ogwiritsidwa ntchito kwambiri (ndipo nthawi zambiri amagwiritsidwa ntchito molakwika) okhudzana ndi kuunikira kwa horticulture.PAR SI muyeso kapena “metric” ngati mapazi, mainchesi kapena ma kilos.M'malo mwake, limafotokoza mtundu wa kuwala kofunikira kuti zithandizire kupanga photosynthesis.

PPF Imaimira photosynthetic photon flux, ndipo imayesedwa mu umol/s.Zimatanthawuza ma photon omwe amatulutsidwa kuchokera pa sekondi iliyonse.PPF imatsimikiziridwa panthawi yomwe chipangizocho chikupangidwira ndikupangidwa.PPF imatha kuyezedwa mu chipangizo chapadera chotchedwa Integrated Sphere.

Mawu ena omwe mumawamva nthawi zambiri-PPFD.PPFD imayimira photosynthetic photon flux density.PPFD ikuyesa kuchuluka kwa ma photon omwe amatera padenga, ndi umol pa sekondi imodzi pa lalikulu mita.PPFD imatha kuyeza ndi sensa m'munda ndikufaniziridwa ndi mapulogalamu.PPFD imaphatikizanso zinthu zambiri kupatula momwe zimakhalira, kuphatikiza kutalika kwake ndi mawonekedwe ake.

Mafunso atatu ofunikira omwe muyenera kuyang'ana kuti ayankhidwe pofufuza njira zowunikira zamaluwa ndi awa:
Kuchuluka kwa PAR komwe kumapanga (kuyezedwa ngati Photosynthetic Photon Flux).
Ndi PAR yochuluka bwanji yochokera pagululi yomwe imapezeka ku zomera (yomwe imayesedwa ngati Photosynthetic Photon Flux Density).
Ndi mphamvu zingati zomwe zimagwiritsidwa ntchito ndi zida kuti PAR ipezeke ku zomera zanu (zoyesedwa ngati Photon Efficiency).

Kuti muthe kuyika ndalama munjira yoyenera yowunikira ulimi wamaluwa kuti mukwaniritse zolinga zanu zakulima ndi bizinesi, muyenera kudziwa PPF, PPFD, ndi luso la photon kuti mupange zisankho zogulira mwanzeru.Komabe, ma metric atatuwa sayenera kugwiritsidwa ntchito ngati zosintha zokha potengera zosankha zogula.Pali zosintha zina zingapo monga mawonekedwe a mawonekedwe ndi coefficient of utilization (CU) zomwe ziyenera kuganiziridwanso.
