Kwezolimo zanamuhla, izindawo zokugcina izithombo zinikeza okungaphezu nje kokufudumala—zinikeza nezimo zokukhanya ezilawulwayo ezibalulekile ekukhuleni kwezitshalo. Ukuchayeka ekukhanyeni okufanele kubalulekile ukuze kuthuthukiswe i-photosynthesis, ebuye ikhulise isivuno sezitshalo. Kodwa singazilungisa kanjani izimo zokukhanya ngaphakathi kwe-greenhouse ukuze sakhe indawo ekahle yezitshalo? Ake sihlole izindlela ezibalulekile zokuphatha ukukhanya futhi siqinisekise ukuthi izitshalo zikhula ngaphansi kwezimo ezingcono kakhulu.
1. Qonda Izidingo Zokukhanya Zezitshalo Zakho
Izitshalo ezahlukene zidinga amazinga ahlukene okukhanya. Isibonelo, izitshalo ezinjengotamatisi nopelepele zikhula kahle endaweni enelanga, lapho ukukhanya okwanele kusheshisa ukukhula kwazo nge-photosynthesis. Ngakolunye uhlangothi, imifino enamahlamvu efana nolethisi nesipinashi idinga ukukhanya kodwa ingahlushwa ukusha kwamaqabunga uma ichayeke elangeni eliqondile kakhulu.
Kubalulekile ukulungisa ukushuba kokukhanya ku-greenhouse ngokusekelwe ezidingweni ezithile zesitshalo ngasinye. Lokhu kusiza ukuvimbela ukuchayeka kancane noma ukuchayeka ngokweqile, kokubili okungakhinyabeza ukukhula.
2. Izinto Ezisetshenziswayo Zithinta Ukudluliswa Kokukhanya
Izinto ezisetshenziselwa ukwakha i-greenhouse zidlala indima ebalulekile ekunqumeni ukuthi kungakanani ukukhanya okungena. Izindlu zokugcina izithombo zengilazi zaziwa ngokudlulisela ukukhanya kwazo okuhle kakhulu, okuvumela ukukhanya kwelanga ukuthi kuhluze futhi kwakhiwe indawo ekahle yezitshalo ezidinga ukukhanya kwelanga okuningi. Kodwa-ke, amapaneli e-polycarbonate noma amafilimu epulasitiki, ngenkathi enikeza ukukhanya okuncane, angcono ekufakeni i-insulating, okwenza kube lula kakhulu ezindaweni ezibandayo.
Ukukhetha into efanele kuyisihluthulelo sokulinganisa amazinga okukhanya nokulawula izinga lokushisa. Ezifundeni ezinokukhanya kwelanga okukhulu, i-greenhouse enokudlulisa ukukhanya okuphezulu iyasiza. Ezindaweni ezibandayo, ukusebenzisa izinto ezinokudlulisa ukukhanya okuphansi kodwa ukwahlukanisa okungcono kungasiza ukugcina izinga lokushisa lizinzile ngenkathi kunikeza ukukhanya okwanele.
Izindawo zokuhlala e- Chengfei Greenhouses, ngeminyaka yobungcweti bokukhiqiza i-greenhouse, inikeza izixazululo ezihambisanayo ezicabangela kokubili ukudluliswa kokukhanya kanye nokufakwa kwe-insulation, okuqinisekisa izimo ezikahle zokukhula zezinhlobonhlobo zezitshalo.
3. Sebenzisa Ukukhanyisa Okwenziwa Ukwengeza Ukukhanya Kwemvelo
Phakathi nezinkathi zonyaka ezinokukhanya kwelanga okwanele, njengezinsuku zasebusika noma eziguqubele, ukukhanya kwemvelo kungase kungahlangabezani nezidingo zezitshalo zakho. Ezimweni ezinjalo, ukukhanya okungeziwe kungasiza. Izibani zokukhulisa i-LED, izibani ze-fluorescent, nezinye izinhlelo zokukhanyisa zokwenziwa zinganikeza ukukhanya okudingekayo kwe-photosynthesis, kusize izitshalo zigcine izinga lokukhula kwazo.
Ukukhanyisa okwenziwayo kuqinisekisa ukuthi izitshalo zithola amazinga okukhanya angashintshi ngisho nangezinsuku ezimnyama, ezisibekele, okuvimbela isivuno esincishisiwe ngenxa yokuntuleka kokukhanya.
4. Phatha Imijikelezo Yokukhanya ukuze Ulawule Izigaba Zokukhula
Umjikelezo wokukhanya ubhekisela esikhathini lapho isitshalo sichayeka ekukhanyeni usuku ngalunye. Izitshalo ezehlukene zinezidingo ezihlukene zomjikelezo wokukhanya. Izitshalo zezinsuku ezinde, ngokwesibonelo, zidinga ukukhanya kwamahora amade ukuze ziqedele umjikelezo wazo wokukhula, kuyilapho izitshalo zezinsuku ezifushane zidinga ukukhanya okuncane.
Ezindlini zokugcina izithombo zesimanje, izinhlelo ezizenzakalelayo zingalawula ukuchayeka kokukhanya ngokusekelwe ezidingweni zesitshalo. Ngokulungisa ubude besikhathi sokuchayeka ekukhanyeni, izindawo zokugcina izithombo zingakhulisa izigaba zokukhula kwezitshalo, njengokuqhakaza izimbali nokuthela izithelo, okuholela ekuvunweni okuphezulu nezitshalo ezinempilo.
5. Izinhlelo Zokukhanyisa Ezithuthukisiwe Zokulungiswa Okuphumelelayo
Ngokuthuthuka kwezobuchwepheshe, izindawo zokugcina izithombo eziningi zobuchwepheshe obuphezulu manje zinezinhlelo zokukhanyisa ezihlakaniphile ezilungisa ngokuzenzakalelayo ukukhanya nokusabalalisa ngaphakathi kwe-greenhouse. Lezi zinhlelo zihlanganisa amanetha ethunzi, amafilimu akhanyayo, namakhethini alungisekayo, konke okuklanyelwe ukuphendula izinguquko ezimweni zokukhanya kwangaphandle.
Lezi zinhlelo zisiza ukugcina amazinga okukhanya alungile ku-greenhouse, ukuqinisekisa ukuthi izitshalo azivezwa izimo zokukhanya ezishintshashintshayo, ikakhulukazi phakathi nezulu eliguqubele noma lina.
6. Izici Zangaphandle: Isimo Sezulu Nezinkathi Zonyaka
Izici zangaphandle, njengesimo sezulu kanye nezinguquko zonyaka, nazo zithinta izimo zokukhanya ngaphakathi kwe-greenhouse. Ngezinsuku eziguqubele noma ngesikhathi sezulu, ukukhanya kwemvelo kuyehla. Ebusika, i-engeli yelanga iba phansi, okuholela ekukhanyeni okubuthakathaka.
Yilapho kuklanywa khona i-greenhouse kanye nezinhlelo zayo zokulawula ukukhanya. Ngokufaka amasistimu okushisa nokukhanyisa okungeziwe, izindawo zokugcina izithombo zingakha indawo ezinzile yezitshalo ngisho nasebusika noma ezifundeni ezinokukhanya kwelanga okulinganiselwe.
Ngokuphatha izimo zokukhanya ngempumelelo, izindlu zokugcina izithombo zingakha indawo ekahle yokutshala izitshalo, okuholela ekuvuneni okuphezulu kanye nomkhiqizo osezingeni elingcono. Kungakhathaliseki ukuthi ngokukhetha izinto ezifanele, ukusebenzisa izibani zokwenziwa, noma ukusebenzisa amasistimu azenzakalelayo athuthukile, indlela efanele yokuphatha ukukhanya ingenza umehluko omkhulu ekukhiqizweni kwezitshalo.
Siyakwamukela ukuba nengxoxo eyengeziwe nathi.
