Ukukhanya okuluhlaza okwesibhakabhaka nokukhanya okubomvu kuseduze kakhulu nejika elisebenzayo le-photosynthesis yezitshalo futhi kuwumthombo wokukhanya odingekayo ekukhuleni kwesitshalo.

Umphumela wokukhanya ekukhuleni kwezitshalo ukukhuthaza i-chlorophyll yezitshalo ukuthi imunce imisoco efana ne-carbon dioxide namanzi ukuze ihlanganise ama-carbohydrate.Isayensi yanamuhla ingavumela izitshalo ukuba zikhule kangcono ezindaweni lapho kungekho khona ilanga, futhi ukudala imithombo yokukhanya ngokuzenzekelayo kungavumela izitshalo ukuba ziqedele inqubo ye-photosynthetic.Izimboni zesimanje zengadi noma zezitshalo zifaka ubuchwepheshe bokukhanya obungeziwe noma ubuchwepheshe bokukhanya bokwenziwa obuphelele.Ososayensi bathola ukuthi izifunda eziluhlaza okwesibhakabhaka nezibomvu ziseduze kakhulu nejika le-photosynthesis yezitshalo, futhi ziwumthombo wokukhanya odingekayo ekukhuleni kwezitshalo.Abantu baye bafunda isimiso sangaphakathi esidingwa izitshalo ukuze simelane nelanga, okuyi-photosynthesis yamaqabunga.I-photosynthesis yamaqabunga idinga isasasa lama-photon angaphandle ukuze kuqedelwe yonke inqubo ye-photosynthetic.Imisebe yelanga iyinqubo yokuphakelwa kwamandla ejatshuliswa ama-photon.

Umthombo wokukhanya we-LED ubizwa nangokuthi umthombo wokukhanya we-semiconductor.Lo mthombo wokukhanya unobude beza obuncane obuncane futhi ungakwazi ukulawula umbala wokukhanya.Ukuyisebenzisela ukuthela izitshalo kukodwa kungathuthukisa izinhlobo zezitshalo.

Ulwazi oluyisisekelo lokukhanya kwezitshalo ze-LED:

1. Amaza ahlukene okukhanya anemiphumela ehlukene ku-photosynthesis yezitshalo.Ukukhanya okudingekayo ku-photosynthesis yezitshalo kunobude begagasi obungaba ngu-400-700nm.Ukukhanya okungu-400-500nm (okuluhlaza okwesibhakabhaka) kanye no-610-720nm (obomvu) kunikela kakhulu ku-photosynthesis.
2. Ama-LED aluhlaza (470nm) kanye nabomvu (630nm) angavele anikeze ukukhanya okudingekayo izitshalo.Ngakho-ke, ukukhetha okuhle kwezibani zezitshalo ze-LED ukusebenzisa inhlanganisela yale mibala emibili.Ngokuphathelene nemiphumela ebonakalayo, izibani zezitshalo ezibomvu neziluhlaza okwesibhakabhaka zivela pink.
3. Ukukhanya okuluhlaza okwesibhakabhaka kungakhuthaza ukukhula kwamaqabunga aluhlaza;ukukhanya okubomvu kuyasiza ekuqhakazeni nasekutheleleni futhi kwandise isikhathi sokuqhakaza.
4. Isilinganiso sama-LED abomvu naluhlaza wezibani zezitshalo ze-LED ngokuvamile siphakathi kuka-4:1--9:1, futhi ngokuvamile ngu-4-7:1.
5. Uma izibani zezitshalo zisetshenziselwa ukugcwalisa izitshalo ngokukhanya, ukuphakama okuvela emaqabunga ngokuvamile kungamamitha angu-0.5, futhi ukuchayeka okuqhubekayo amahora angu-12-16 ngosuku kungashintsha ngokuphelele ilanga.

Sebenzisa ama-LED semiconductor bulbs ukuze ulungiselele umthombo wokukhanya ofaneleka kakhulu wokukhula kwezitshalo

Izibani ezinombala ezibekwe ngokulingana zingenza ama-strawberry notamatisi abe mnandi futhi abe nomsoco.Ukukhanyisa izithombo ze-holly ngokukhanya ukulingisa i-photosynthesis yezitshalo ngaphandle.I-Photosynthesis isho inqubo lapho izitshalo eziluhlaza zisebenzisa amandla okukhanya ngama-chloroplast ukuze ziguqule isikhutha namanzi kube izinto eziphilayo ezigcina amandla futhi zikhiphe umoya-mpilo.Ukukhanya kwelanga kwakhiwe ngemibala ehlukene yokukhanya, futhi imibala ehlukene yokukhanya ingaba nemiphumela ehlukene ekukhuleni kwezitshalo.

Izithombo ze-holly ezihlolwe ngaphansi kokukhanya okunsomi zakhula zaba zinde, kodwa amaqabunga ayemancane, izimpande zingashoni, futhi zibukeka zingondlekile.Izithombo ngaphansi kokukhanya okuphuzi azifushane nje kuphela, kodwa amaqabunga abukeka engenakuphila.I-holly ekhula ngaphansi kokukhanya okuxubile okubomvu nokuluhlaza okwesibhakabhaka ikhula kahle kakhulu, ayinamandla kuphela, kodwa uhlelo lwempande luthuthukisiwe kakhulu.I-bulb ebomvu ne-blue bulb yalo mthombo wokukhanya we-LED zilungiswe ngesilinganiso esingu-9:1.

Imiphumela ibonisa ukuthi ukukhanya okungu-9:1 okubomvu nokuluhlaza okwesibhakabhaka kuyinzuzo kakhulu ekukhuleni kwezitshalo.Ngemva kokuba lo mthombo wokukhanya ushisiwe, izithelo ze-strawberry notamatisi zigcwele, futhi okuqukethwe ushukela novithamini C kukhuphuka kakhulu, futhi akukho mkhuba ongenalutho.I-irradiation eqhubekayo amahora angu-12-16 ngosuku, ama-strawberries notamatisi atshalwe ngaphansi komthombo onjalo wokukhanya kuyoba mnandi kakhulu kunezithelo ezivamile zokushisa.
