LED yamurika ibibazo muri Horticulture

Birumvikana ko hari imbogamizi mubuhanga ubwo aribwo bwose bugenda bugaragara, kandi hariho ingorane zo kumurika indabyo zishingiye ku buhinzi. Kugeza ubu, uburambe bwikoranabuhanga rikomeye-rimurika riracyari rito. Ndetse n'abahanga mu buhinzi bw'imboga bamaze imyaka myinshi bakora ubushakashatsi kuri “formulaire yoroheje” y'ibimera. Bimwe muribi "formulaire" ntibishoboka muri iki gihe.

Abakora amatara yo muri Aziya bakunze gushyirwa mubicuruzwa bihendutse ariko biciriritse, kandi ibicuruzwa byinshi byo hasi ku isoko ntibabura ibyemezo bifatika nka UL amanota, hamwe na LM-79 luminaire na raporo ya LM-80 LED. Abahinzi benshi bagerageje gukoresha amatara ya LED hakiri kare, ariko bumva bababajwe n'imikorere mibi ya luminaire, bityo amatara ya sodium yumuvuduko ukabije aracyari igipimo cya zahabu muruganda.

Nibyo, hari byinshi byiza byo mu rwego rwo hejuru LED ikura ibicuruzwa kumurika kumasoko. Nyamara, abahinzi borozi nindabyo baracyakeneye ibipimo byiza bijyanye no gusaba. Kurugero, Sosiyete y'Abanyamerika ishinzwe ubuhinzi n’ibinyabuzima (ASABE) Komite ishinzwe kumurika ubuhinzi yatangiye guteza imbere ibipimo bisanzwe mu 2015. Uyu murimo urimo gusuzuma ibipimo bijyanye na PAR (Photosynthetically Active Radiation). Urwego rwa PAR rusobanurwa nkumurongo wa 400-700 nm, aho fotone itwara fotosintezeza. Ibipimo bisanzwe bifitanye isano na PAR birimo fotosintetike ya foton flux (PPF) hamwe na fotosintezitike ya foton flux yuzuye (PPFD).

Ibisubizo n'ibipimo

"Resept" na metrics birahujwe kuko umuhinzi akenera ibipimo kugirango amenye niba igihingwa luminaire gitanga ubukana nogukwirakwiza amashanyarazi (SPD), arimo "resept".

Ubushakashatsi bwambere bwibanze ku isano yo kwinjiza chlorophyll n'imbaraga zidasanzwe, kuko chlorophyll nurufunguzo rwibikorwa bya fotosintezeza. Ubushakashatsi bwakorewe muri laboratoire bwerekanye ko ingufu ziri hejuru yubururu n umutuku zihura nimpinga zo kwinjirira, mugihe ingufu zicyatsi zerekana ko zitinjira. Ubushakashatsi bwambere bwatumye habaho isoko ryinshi ryibara ryijimye cyangwa ryijimye ku isoko.

Nyamara, imitekerereze ya none yibanze kumurika itanga ingufu zingana mubururu nubururu butukura, ariko icyarimwe itanga urumuri runini rwo kumurika nkizuba.

Itara ryera ni ngombwa cyane

Gukoresha gusa amatara yo gukura yumutuku nubururu LED yarashaje. Iyo ubonye igicuruzwa gifite iyi sprifike, gishingiye kubumenyi bwa kera kandi akenshi ntibwumva nabi. Impamvu abantu bahitamo ubururu numutuku ni ukubera ko iyi mpinga yuburebure ihuye nu murongo wo kwinjiza chlorophyll a na b itandukanijwe mu kizamini. Uyu munsi tuzi ko uburebure bwumucyo murwego rwa PAR ari ingirakamaro mugutwara fotosintezeza. Ntagushidikanya ko spekure ari ngombwa, ariko ifitanye isano na morphologie yibimera nkubunini n'imiterere.

Turashobora guhindura uburebure nindabyo byibimera duhindura urwego. Abahinzi bamwe bahora bahindura ubukana bwurumuri na SPD kuberako ibimera bifite ikintu gisa nigitekerezo cyizunguruka, kandi ibimera byinshi bifite injyana idasanzwe nibisabwa "formulaire".

Ihuriro nyamukuru ritukura nubururu rishobora kuba ryiza kubibabi byamababi nka salitusi. Ariko yavuze kandi ko ku bimera by’indabyo, harimo n’inyanya, ubukana bukomera kuruta umwihariko udasanzwe, 90% y’ingufu ziri mu itara ryinshi rya sodium iri mu gace k'umuhondo, naho lumens iri mu gihingwa cy’indabyo amatara y’indabyo (lm) ), lux (lx) Kandi efficacy irashobora kuba yukuri kuruta ibipimo bya PAR.

Abahanga bakoresha 90% bya fosifori yahinduwe na LED yera muri luminaire yabo, abasigaye bakaba LED itukura cyangwa itukura cyane, naho urumuri rwera rushingiye kuri LED rutanga ingufu zose z'ubururu zikenewe kugirango umusaruro ube mwiza.
