Ukukhanya kudlala indima ebalulekile ekukhuleni kwezitshalo. Nge-Photosynthesis, izitshalo ziguqula amandla okukhanya abe amandla amakhemikhali, asekela ukuthuthukiswa kwawo kanye nokuhlanganiswa kwezinto ezidingekayo zokukhula. Kodwa-ke, izitshalo ezahlukahlukene zinezidingo ezihlukahlukene ezilula. I-spectrum kanye nokuqina kokukhanya akugcini nje ngokuthonya ijubane lokukhula kwezitshalo kodwa futhi kuthinta i-morphology yabo, izimbali kanye nezithelo. Ezokulima abamba ukushisa, ukhetha i-spectrum efanelekile kanye nokuqina okukhanyayo kubalulekile ukuze unikeze isivuno sezembeso nekhwalithi. Kulesi sihloko, sizohlola ukuthi i-Spyctra ekhanyayo kanye namandla ahlukile kanjani izitshalo nokuthi abatshali bezimvula bangasebenzisa kanjani lolu lwazi ukukhulisa ukukhula kwezitshalo.
1. I-Light Spectrum ithinta kanjani ukukhula kwezitshalo?
I-Light Spectrum isho uhla lwama-wavelength okukhanya, futhi ingxenye ngayinye ye-spectrum inomthelela ohlukile ekukhuleni kwezitshalo. Ukukhanya okukhanyayo okuvamile kufaka phakathi ukukhanya okuluhlaza okwesibhakabhaka, okubomvu, nokuhlaza okuluhlaza, futhi ngalinye linomphumela oyingqayizivele ezitshalweni.
1.1 ukukhanya okuluhlaza okwesibhakabhaka
I-Blue Light (Wavelength ephakathi kuka-450-495 nm) ibalulekile ekukhuleni kwezitshalo, ikakhulukazi ngokuya nge-levent ethuthukisiwe kanye nesitshalo se-morphology ephelele. I-Blue Light ikhuthaza izithombe ze-photosynthesis kanye ne-chlorophyll synthesis, ngaleyo ndlela zithuthukisa ukusebenza kahle kwe-photosynthesis. Ngemifino enamaqabunga afana ne-lettuce nesipinashi, ukukhanya okuluhlaza okwesibhakabhaka kuzuzisa ikakhulukazi ukwandisa usayizi wamaqabunga nobuningi.
1.2 ukukhanya okubomvu
Ukukhanya okubomvu (ama-wavelength aphakathi kuka-620-750 NM) kungenye into ebalulekile yokukhanya kwezitshalo. Idlala indima enkulu eziqhakaza izimbali, izithelo, kanye nokuthuthukiswa kwezitshalo. Ukukhanya okubomvu kuvusa ukuqina kwesiqu futhi kusekela ukukhiqizwa kwe-phytochrome, okuthonya ukukhula kwezitshalo nemijikelezo yokuzala.
2. Ukukhanya okukhanyayo kanye nomthelela wayo ekukhuleni kwezitshalo
Ngenkathi i-spectrum ekhanyayo ibalulekile, ubukhulu bokukhanya budlale indima ebalulekile ekuthuthukisweni kwezitshalo. Ukuqina okukhanyayo kubhekisa enanini lokukhanya okutholakalayo kwezitshalo, futhi kungathinta izinga le-photosynthesis, usayizi wesitshalo, kanye nempilo yonke yesitshalo.
2.1 ubukhulu bokukhanya okuphezulu
Ukukhanya okuphezulu okuphezulu kukhuthaza i-photosynthesis eqinile, okuholela ekukhuleni kwesitshalo okusheshayo kanye nesivuno esandayo. Izitshalo ezinjengotamatisi kanye nopelepele zidinga ukuqina okuphezulu ukukhiqiza izithelo kahle. Kodwa-ke, ubukhulu obukhulu bokukhanya bungadala ukucindezela ezitshalweni, okuholele ekuvutheni kwamaqabunga noma ukukhula okuvinjelwe. Kubalulekile ukulinganisa ubukhulu bokukhanya ukuqinisekisa impilo ephezulu yesitshalo.
2.2 ubukhulu obuphansi bokukhanya
Ukuqina okukhanyayo kungakhawulela izithombe, okuholela ekukhuleni okuhamba kancane nezitshalo ezincane. Ngenkathi ezinye izitshalo, ezinjengemifino ethile enamahlamvu, zingabekezelela izimo eziphansi zokukhanya, izilimo eziningi zidinga ukukhanya okwanele ukuze zichume. Abatshali abamba ukushisa bangangezelela ukukhanya kwemvelo ngokukhanyisa okwenziwe, ikakhulukazi ngesikhathi sezinyanga zobusika noma ezifundeni ezinokukhanya kwelanga okuncane.
3. Abatshali abamba ukushisa bangaba kanjani basebenzise izimo zokukhanya?
Ngokuqonda umthelela wokukhanya okukhanyayo kanye nokuqina, abatshali abamba ukushisa bangakhulisa izimo zabo zokukhanya ukukhuthaza izilimo ezinempilo nezikhiqizayo. Kusetshenziswa inhlanganisela yokukhanyisa kwemvelo nokufakelwa (njenge-LED kukhula amalambu), abatshali bangadala indawo efanelekile yokukhula kwezitshalo, ukuqinisekisa ukuthi ukukhanya kutholakala ngamanani afanele kanye nama-spectrums ngaso sonke isikhathi.
Ngamathuluzi afanele namasu, njengokulawula imijikelezo yokukhanya nokusebenzisa imithombo ekhethekile yokukhanya, ukulima ukushisa kungasekela izitshalo ezinempilo unyaka wonke, ngisho nasezinkathini ezikhanyayo.
Uyemukelwa ukuze ube nengxoxo eyengeziwe nathi.
