Sivame ukuthola izingcingo ezivela kumakhasimende ukubuza mayelana nezimiso greenhouseizibani zokukhula kwezitshalo, isikhathi sokukhanya esingeziwe, kanye nomehluko phakathiAmalambu okukhula kwezitshalo ze-LEDkanye nezibani ze-high-pressure mercury (sodium).Namuhla, sizoqoqa ezinye izimpendulo zemibuzo esemqoka amakhasimende akhathazeke ngayo ukuze uthole inkomba yakho.Uma unentshisekelo ekukhanyeni kwezitshalo futhi ungathanda ukuqhubeka nokuxhumana ne-Wei Zhaoye Optoelectronics, sicela ushiye umlayezo noma usishayele.
Isidingo sokukhanyisa okungeziwe kuma-greenhouses
Eminyakeni yamuva, ngokuqoqwa nokuvuthwa kolwazi nobuchwepheshe,izibani zokukhula kwezitshalo, ezihlale zibhekwa njengophawu lwezolimo zesimanje ezisezingeni eliphezulu eChina, ziye zangena kancane kancane emkhakheni wombono wabantu.Ngokujula kocwaningo lwe-spectral, kutholwe ukuthi ukukhanya kumabhendi we-wavelength ehlukene kunemiphumela ehlukene ezitshalweni ezigabeni zokukhula ezihlukahlukene.Inhloso yokukhanyisa ngaphakathi kwe-greenhouse ukukhulisa ukukhanya okwanele usuku lonke.Ikakhulu isetshenziselwa ukutshala imifino, ama-roses ngisho nezithombo ze-chrysanthemum ekwindla sekwephuzile nobusika.
Ezinsukwini ezinamafu nokukhanya okuphansi, ukukhanyisa okwenziwayo kuyadingeka.Nikeza izitshalo okungenani amahora angu-8 okukhanya ngosuku ebusuku, futhi isikhathi sokukhanya kufanele simiswe nsuku zonke.Kodwa ukuntuleka kokuphumula ebusuku nakho kungaholela ekukhuleni kwezitshalo nokuncipha kwesivuno.Ngaphansi kwezimo zemvelo ezimisiwe ezifana ne-carbon dioxide, amanzi, imisoco, izinga lokushisa kanye nomswakama, usayizi "we-photosynthetic flux density PPFD" phakathi kwendawo yokugcwala ukukhanya nendawo yesinxephezelo sokukhanya sesitshalo esithile inquma ngokuqondile izinga lokukhula kwesitshalo. .Ngakho-ke, umthombo wokukhanya osebenza kahle we-PPFD Combination uyisihluthulelo sokukhiqiza kwefekthri.
Ukukhanya kuwuhlobo lwemisebe kagesi.Ukukhanya okungabonwa iso lomuntu kubizwa ngokuthi ukukhanya okubonakalayo, okusukela ku-380nm kuya ku-780nm, futhi umbala okhanyayo usukela kokunsomi uye kobomvu.Ukukhanya okungabonakali kufaka phakathi ukukhanya kwe-ultraviolet nokukhanya kwe-infrared.Amayunithi e-Photoometry kanye ne-colorimetry asetshenziselwa ukukala izici zokukhanya.Ukukhanya kukho kokubili izibaluli zobuningi nekhwalithi.Owokuqala ukuqina kokukhanya kanye ne-photoperiod, futhi yokugcina ikhwalithi yokukhanya noma ukusatshalaliswa kwamandla okuvumelanayo.Ngesikhathi esifanayo, ukukhanya kunezakhi zezinhlayiya kanye nezakhiwo zamagagasi, okungukuthi, ububili bezinhlayiyana zamagagasi.Ukukhanya kunezinto ezibonakalayo kanye nezakhiwo zamandla.Izindlela zokulinganisa eziyisisekelo ku-photometry kanye ne-colorimetry.① Ukukhanya okukhanyayo, iyunithi ye-lumens lm, isho isamba senani lokukhanya elikhishwa umzimba okhanyayo noma umthombo wokukhanya ngesikhathi seyunithi, okungukuthi, ukuguquguquka okukhanyayo.②Amandla okukhanya: uphawu I, iyunithi ye-candela cd, ukugeleza okukhanyayo okukhishwa umzimba okhanyayo noma umthombo wokukhanya ngaphakathi kwe-engeli eyodwa eqinile endaweni ethile.③Ukukhanya: Uphawu E, iyunithi lux lm/m2, ukugeleza okukhanyayo okukhanyiswa umzimba okhanyayo endaweni yeyunithi yento ekhanyisiwe.④Ukukhanya: Uphawu L, iyunithi ye-Nitr, cd/m2, ukugeleza okukhanyayo kwento ekhanyayo endaweni ethile, iyunithi ye-engeli eqinile, indawo yeyunithi.⑤ Ukusebenza kahle okukhanyayo: Iyunithi ilumens ngewathi ngayinye, lm/W.Ikhono lomthombo wokukhanya kagesi lokuguqula amandla kagesi abe ukukhanya livezwa ngokuhlukanisa ukugeleza okukhanyayo okukhishiwe ngokusetshenziswa kwamandla.⑥ Ukusebenza kahle kwesibani: Kuphinde kubizwe nge-coefficient yokukhanya, iyindinganiso ebalulekile yokulinganisa ukusebenza kahle kwezibani.Kuyisilinganiso phakathi kokukhishwa kwamandla okukhanya ngesibani kanye nokuphuma kwamandla okukhanya ngomthombo wokukhanya ongaphakathi kwesibani.⑦Isilinganiso sobude besikhathi sokuphila: iyunithi yehora, ibhekisela enanini lamahora lapho u-50% weqoqo lama-bulb onakalisiwe.⑧Impilo yezomnotho: ihora leyunithi, kucatshangelwa ukulimala kwesibani kanye nokuncishiswa kokuphuma kwe-beam, okukhiphayo okubanzi kwe-beam kuncishiswa enanini elithile lamahora.Lesi silinganiso singu-70% emithonjeni yokukhanya yangaphandle kanye nama-80% emithonjeni yokukhanya yasendlini njengamalambu e-fluorescent.⑨ Izinga lokushisa lombala: Uma umbala wokukhanya okhishwa umthombo wokukhanya ufana nombala wokukhanya okhishwa umzimba omnyama ezingeni elithile lokushisa, izinga lokushisa lomzimba omnyama libizwa ngokuthi izinga lokushisa lombala lomthombo wokukhanya.Izinga lokushisa lombala lomthombo wokukhanya lihlukile, futhi umbala okhanyayo nawo uhlukile.Ukushisa kombala ngaphansi kwe-3300K kunomoya ozinzile nomuzwa ofudumele;izinga lokushisa lombala phakathi kuka-3000 no-5000K izinga lokushisa lombala eliphakathi nendawo, elinomuzwa oqabulayo;izinga lokushisa lombala elingaphezu kuka-5000K linomuzwa obandayo.⑩ Izinga lokushisa lombala nokunikezwa kombala: Ukunikezwa kombala komthombo okhanyayo kuboniswa inkomba yokunikeza umbala, ebonisa ukuthi ukuchezuka kombala wento engaphansi kokukhanya uma kuqhathaniswa nombala wokukhanya okuyireferensi (ukukhanya kwelanga) kungabonisa ngokugcwele izici zombala. yomthombo wokukhanya.
Ukuhlelwa kwesikhathi sokukhanya kokugcwalisa
1. Njengokukhanya okungeziwe, kungathuthukisa ukukhanya nganoma yisiphi isikhathi sosuku futhi kunwebe isikhathi sokukhanyisa esisebenzayo.
2. Kungakhathaliseki ukuthi kuhwalala noma ebusuku, inganweba ngempumelelo futhi ilawule ngokwesayensi ukukhanya okudingwa izitshalo.
3. Ezindlini zokugcina izithombo noma kuma-laboratories ezitshalo, kungashintsha ngokuphelele ukukhanya kwemvelo futhi kukhuthaze ukukhula kwezitshalo.
4. Sixazulule ngokuphelele isimo sokuncika esimweni sezulu ngesikhathi sokutshala izithombo, futhi uhlele isikhathi ngokufanele ngokwedethi yokulethwa kwezithombo.
Ukukhanya kokukhula kwezitshaloukukhetha
Ngokukhetha imithombo yokukhanya ngokwesayensi kuphela lapho singalawula kangcono isivinini kanye nekhwalithi yokukhula kwezitshalo.Uma sisebenzisa imithombo yokukhanya yokwenziwa, kufanele sikhethe ukukhanya kwemvelo okuseduze kakhulu nokuhlangabezana nezimo ze-photosynthesis zezitshalo.Linganisa ukukhanya kwe-photosynthetic flux density PPFD (Photosynthetic PhotonFlux Density) ekhiqizwa umthombo wokukhanya esitshalweni ukuze ubambe izinga le-photosynthesis yesitshalo kanye nokusebenza kahle komthombo wokukhanya.Inani lamaphothoni asebenza kahle nge-photosynthetically liqala i-photosynthesis yesitshalo ku-chloroplast: okuhlanganisa ukusabela okukhanyayo nokusabela okumnyama okulandelayo.
Izibani zokukhula kwezitshalokufanele ibe nezici ezilandelayo
1. Guqula amandla kagesi abe amandla akhazimulayo ngendlela efanele.
2. Thola ukushuba kwemisebe ephezulu phakathi kwebanga elisebenzayo le-photosynthesis, ikakhulukazi imisebe ye-infrared ephansi (imisebe eshisayo)
3. Ububanzi bemisebe yesibani sihlangabezana nezimfuneko zemvelo zezitshalo, ikakhulukazi endaweni esebenza kahle ye-spectral ye-photosynthesis.
Isimiso sokugcwalisa ukukhanya kwezitshalo
Ukukhanya kokugcwalisa isitshalo se-LED kuwuhlobo lweisibani sezitshalo.Isebenzisa ama-light-emitting diode (ama-LED) njengomthombo wokukhanya futhi isebenzisa ukukhanya esikhundleni sokukhanya kwelanga ukudala indawo yokukhula nokukhula kwezitshalo ngokuvumelana nemithetho yokukhula kwezitshalo.Izibani zezitshalo ze-LED zisiza ukufinyeza umjikelezo wokukhula kwezitshalo.Umthombo wokukhanya ikakhulukazi wakhiwe imithombo yokukhanya ebomvu nokuluhlaza okwesibhakabhaka.Isebenzisa ibhande lokukhanya elizwela kakhulu lezitshalo.I-wavelength yokukhanya ebomvu isebenzisa u-630nm no-640~660nm, futhi ubude beza beza bokukhanya okuluhlaza okwesibhakabhaka busebenzisa u-450~460nm no-460~470nm.Le mithombo yokukhanya ingavumela izitshalo ukuthi zikhiqize i-photosynthesis efanelekile, okuvumela izitshalo ukuba zifinyelele ukukhula okuhle.Indawo ekhanyayo ingenye yezinto ezibalulekile zemvelo ezibalulekile ekukhuleni nasekuthuthukeni kwezitshalo.Ukulawula i-morphology yezitshalo ngokulungiswa kwekhwalithi yokukhanya kuwubuchwepheshe obubalulekile emkhakheni wokulima indawo.
