Xa kufika ixesha lemvula, ukukhanya kwelanga kuye kwaba yinto engaqhelekanga.
Kwabo bathanda ukutyala izityalo ezinamagqabi okanye izityalo ezinamagqabi, kunokuthiwa kuyaxhalabisa.
Izityalo ezithambileyo zithanda ukukhanya kwelanga kwaye zithanda indawo enomoya opholileyo. Ukungabikho kokukhanya kuya kuzenza zibe zincinci kwaye zibe zinde, nto leyo ezenze zibe mbi. Ukungena komoya okwaneleyo kunokubangela ukuba iingcambu zazo zibole, kwaye ezo zinenyama zinokubuna okanye zife.
Abahlobo abaninzi abakhulisa izityalo ezinamanzi amdaka bakhetha ukusebenzisa izibane zezityalo ukuzalisa izityalo ezinamanzi amdaka.
Ngoko ke, ungakhetha njani isibane esipheleleyo?
Masiqale siqonde imiphumo yee-wavelengths ezahlukeneyo zokukhanya kwizityalo:
280 ~ 315nm: impembelelo encinci kwiinkqubo ze-morphology kunye ne-physiological;
315 ~ 400nm: Ukufunxwa kancinci kwe-chlorophyll, echaphazela isiphumo se-photoperiod kwaye ithintele ukunwebeka kwesiqu;
400 ~ 520nm (eluhlaza okwesibhakabhaka): Umlinganiselo wokufunxwa kwe-chlorophyll kunye ne-carotenoids ngowona mkhulu, kwaye unempembelelo enkulu kwi-photosynthesis;
520 ~ 610nm (eluhlaza): izinga lokufunxwa kwepigment aliphezulu;
610 ~ 720nm (ubomvu): Izinga eliphantsi lokufunxwa kwe-chlorophyll, elichaphazela kakhulu i-photosynthesis kunye nemiphumo ye-photoperiod;
720 ~ 1000nm: Izinga eliphantsi lokufunxa, likhuthaza ukwandiswa kweeseli, lichaphazela ukudubula kweentyantyambo kunye nokuhluma kwembewu;
＞1000nm: Iguqulwe yaba bubushushu.
Abahlobo abaninzi bathenge zonke iintlobo zezibane zokukhulisa izityalo kwi-intanethi, kwaye abanye bathi ziyasebenza emva kokuzisebenzisa, kwaye abanye bathi azisebenzi kwaphela. Injani imeko yokwenyani? Isibane sakho asisebenzi, mhlawumbi kungenxa yokuba uthenge isibane esingalunganga.
Umahluko phakathi kwezibane zokukhula kwezityalo kunye nezibane eziqhelekileyo:
Umfanekiso ubonisa lonke i-spectrum yokukhanya okubonakalayo (ukukhanya kwelanga). Kuyabonakala ukuba ibhendi yamaza enokukhuthaza ukukhula kwezityalo ithambekele kakhulu kubomvu noblowu, indawo egutyungelwe ngumgca oluhlaza kumfanekiso. Yingakho izibane zokukhula kwezityalo ze-LED ezithengwa kwi-intanethi zisebenzisa ii-lamp beads ezibomvu neziblowu.
Funda ngakumbi malunga neempawu kunye nemisebenzi yezibane zezityalo ze-LED:
1. Iindidi ezahlukeneyo zamaza okukhanya zinefuthe elahlukileyo kwifotosinthesisi yezityalo. Ukukhanya okufunekayo kwifotosinthesisi yezityalo kunobude bamaza obumalunga ne-400-700nm. Ukukhanya okungu-400-500nm (oluhlaza okwesibhakabhaka) kunye no-610-720nm (obomvu) negalelo elikhulu kwifotosinthesisi.
2. Ii-LED eziluhlaza okwesibhakabhaka (470nm) kunye nezibomvu (630nm) zinokubonelela ngokukhanya okufunekayo kwizityalo, ngoko ke ukhetho olufanelekileyo kukusebenzisa indibaniselwano yale mibala mibini. Ngokuphathelele imiphumo ebonakalayo, izibane zezityalo ezibomvu neziluhlaza okwesibhakabhaka zipinki.
3. Ukukhanya okuluhlaza okwesibhakabhaka kunceda i-photosynthesis yezityalo, enokukhuthaza ukukhula kwamagqabi aluhlaza, ukwenziwa kweeproteni, kunye nokwakheka kweziqhamo; ukukhanya okubomvu kunokukhuthaza ukukhula kwe-rhizome yezityalo, kuncede ekudubuleni nasekuqhameni iziqhamo kwaye kuqhubeke ixesha elide, kwaye kwandise isivuno!
4. Umlinganiselo wee-LED ezibomvu neziluhlaza okwesibhakabhaka zezibane zezityalo ze-LED uhlala uphakathi kwe-4:1-9:1, ngesiqhelo uphakathi kwe-6-9:1.
5. Xa izibane zezityalo zisetyenziselwa ukongeza ukukhanya kwezityalo, ukuphakama ukusuka emagqabini kudla ngokuba malunga ne-0.5-1 yeemitha, kwaye ukuvezwa rhoqo iiyure ezili-12-16 ngosuku kunokutshintsha ngokupheleleyo ilanga.
6. Isiphumo sibaluleke kakhulu, kwaye izinga lokukhula likhawuleza ngokuphindwe kathathu kunelo lezityalo eziqhelekileyo ezikhula ngokwendalo.
7. Sombulula ingxaki yokunqongophala kwelanga ngexesha leemvula okanye kwigreenhouse ebusika, kwaye ukhuthaze i-chlorophyll, i-anthocyanin kunye ne-carotene efunekayo kwi-photosynthesis yezityalo, ukuze iziqhamo kunye nemifuno zivunwe nge-20% kwangethuba, nto leyo eyandisa isivuno nge-3 ukuya kwi-50%, nangaphezulu. Ubumnandi beziqhamo kunye nemifuno buyanciphisa izinambuzane nezifo.
8. Umthombo wokukhanya we-LED ukwabizwa ngokuba ngumthombo wokukhanya we-semiconductor. Olu hlobo lomthombo wokukhanya lunobude obuncinci kwaye lunokukhupha ukukhanya kobude obuthile, ngoko ke umbala wokukhanya unokulawulwa. Ukuwusebenzisa ukukhanyisela izityalo kuphela kunokuphucula iintlobo zezityalo.
9. Izibane zokukhulisa izityalo ze-LED zinamandla aphantsi kodwa zisebenza kakuhle kakhulu, kuba ezinye izibane zikhupha i-spectrum epheleleyo, oko kukuthi, kukho imibala esi-7, kodwa into efunekayo zizityalo kukukhanya okubomvu kunye nokukhanya okuluhlaza okwesibhakabhaka, ngoko ke uninzi lwamandla okukhanya kwezibane zemveli alunamsebenzi, ngoko ke ukusebenza kakuhle kuphantsi kakhulu. Isibane sokukhulisa izityalo se-LED sinokukhupha ukukhanya okubomvu nokuluhlaza okomhlaza okufunwa zizityalo, ngoko ke ukusebenza kakuhle kuphezulu kakhulu. Yingakho amandla ee-watts ezimbalwa zesibane sokukhulisa izityalo se-LED engcono kunesibane esinamandla amashumi ee-watts okanye amakhulu ee-watts.
Esinye isizathu kukungabikho kokukhanya okuluhlaza okwesibhakabhaka kwizibane zesodium zemveli, kunye nokungabikho kokukhanya okubomvu kwizibane zemercury kunye nezibane ezonga amandla. Ke ngoko, isiphumo sokukhanya esongezelelweyo sezibane zemveli sibi kakhulu kunezibane ze-LED, kwaye sigcina amandla angaphezu kwama-90% xa kuthelekiswa nezibane zemveli. Ixabiso linciphile kakhulu.
