Ukukhanya kungumthombo wamandla ekwenzeni i-photosynthesis, ngakho-ke ukukhanya okwanele kungenye yezimo ezibaluleke kakhulu ekukhuleni nasekuthuthukiseni okuhle kwezitshalo. Isikhathi esidingekayo sokukhanya kwelanga ngokuthuthukiswa okujwayelekile kwezindawo zokushisa okushisa ngokuvamile kuvama amahora angu-8-10, ezinye izitshalo ezinothando, isibonelo, ama- eggplant , zidinga ngisho namahora angu-12. Yingakho, ukuze kuthuthukiswe izimo ezifanele, ukukhanya okungokwemvelo kwe-greenhouse kufakwe amandla kagesi, okusebenzayo.
Njengomthetho, umbuzo wokuthi ukukhanyisa kanjani ku-greenhouse uxazululwa ngesikhathi esifanayo nokwakhiwa kwawo futhi uhlanganisa zonke izixazululo zobuchwepheshe: ikhebula eliyinhloko, ukuhlela nokufakwa kweseyili kagesi, ukubalwa kwenombolo edingekayo nendawo yezibani. Ngokwezinga elikhulu, uhlelo lwesimiso esithile sokukhanyisa kuxhomeke kuhlobo lwezibani ezisetshenzisiwe.
Izinhlobo zezibani zokukhanyisa kwe-greenhouse
Ukuze kulungiswe ukukhanya kokufakelwa kwezindawo zokugcina izithombo, kunezinhlobo eziningana zezibani ezisetshenzisiwe, ngayinye yazo inezinzuzo zayo:
- Luminescent. Ngenxa yezindawo zabo ezikhethekile, lezi zibani kuze kube yamuva kwaba umholi ongamangalelwa ohlelweni lwamagumbi okugcina izithombo. Akulona neze ukufutheka, ngakho ayithinti i-microclimate ngaphakathi kwesakhiwo. Ngaphezu kwalokho, izibani ze-fluorescent azibizi futhi ziyadla ubuncane kagesi.
- Izicabha eziphezulu ze-sodium izibani. Izimo zemisebe yama-spectral yalolu hlobo lwezibani zisetshenziselwa kuphela izigaba zokuzala zezitshalo, ngezinye izikhathi izibani ze-sodium zokukhanyisa izithombo zokugcina izithombo zingathinta umkhiqizo wezitshalo.
- Izibani ze-LED. Inzuzo enkulu yalezi zibani ukubunjwa okubukeka kwe-flux ukukhanya okufanekisela izitshalo. Ngaphezu kwalokho, ukukhanyisa kwe- LED ezindlini zokugcina izithombo kufana nokusetshenziswa okuphezulu kwamandla okukhanya (ukusebenza kahle kufinyelela kuma-100%).
Ukukhetha uhlobo oluthile lwesibani ngokuyinhloko kuxhomeke ekudingeni izitshalo esigabeni ngasinye sokuthuthukiswa, izici zendawo yokushisa kanye nenani lokukhanya kwemvelo.
