Sihlala sifumana iifowuni ezivela kubathengi ukuba babuze malunga nemigaqo ye-greenhouseizibane zokukhula kwezityalo, ixesha lokukhanya elongezelelweyo, kunye nomahluko phakathiIzibane zokukhula kwezityalo ze-LEDkunye nezibane ezinoxinzelelo oluphezulu lwemercury (sodium).Namhlanje, siza kuqokelela ezinye iimpendulo kwimibuzo ephambili abathengi abaxhalabileyo malunga nereferensi yakho.Ukuba unomdla ekukhanyeni kwezityalo kwaye ungathanda ukunxibelelana ngakumbi ne-Wei Zhaoye Optoelectronics, nceda ushiye umyalezo okanye usitsalele umnxeba.
Imfuneko yokukhanyisa okongeziweyo kwii-greenhouses
Kwiminyaka yakutshanje, kunye nokuqokelela kunye nokukhula kolwazi kunye neteknoloji,izibane zokukhula kwezityalo, ebisoloko igqalwa njengophawu lwezolimo zanamhlanje ezikumgangatho ophezulu eTshayina, ngokuthe ngcembe ziye zangena kumbono wabantu.Ngokunzulu kophando lwe-spectral, kuye kwafunyaniswa ukuba ukukhanya kwiibhendi ezahlukeneyo zamaza kuneempembelelo ezahlukeneyo kwizityalo kwizigaba ezahlukeneyo zokukhula.Injongo yokukhanyisa ngaphakathi kwi-greenhouse kukwandisa ukukhanya okwaneleyo imini yonke.Isetyenziselwa ikakhulu ukutyala imifuno, iirozi kunye nezithole zechrysanthemum ngasekupheleni kwekwindla nasebusika.
Kwiintsuku ezinamafu kunye nokukhanya okuphantsi kokukhanya, ukukhanyisa okwenziweyo kuyimfuneko.Nika izityalo ubuncinane iiyure ezisi-8 zokukhanya ngosuku ebusuku, kwaye ixesha lokukhanya kufuneka lilungiswe yonke imihla.Kodwa ukungabikho kokuphumla ebusuku kunokukhokelela ekukhuleni kwezityalo kunye nokunciphisa izivuno.Ngaphantsi kweemeko ezimiselweyo zokusingqongileyo ezifana nekharbon diokside, amanzi, izondlo, ubushushu kunye nokufuma, ubungakanani be "photosynthetic flux density PPFD" phakathi kwendawo yokukhanya kunye nembuyekezo yokukhanya yesityalo esithile imisela ngokuthe ngqo isantya sokukhula kwesityalo. .Ke ngoko, umthombo wokukhanya osebenzayo wePPFD Umdibaniso sisitshixo kwimveliso yemveliso yezityalo.
Ukukhanya luhlobo lwemitha ye-electromagnetic.Ukukhanya okubonwa liliso lomntu kubizwa ngokuba kukukhanya okubonakalayo, ukusuka kwi-380nm ukuya kwi-780nm, kunye nombala okhanyayo ukusuka kwimfusa ukuya kubomvu.Ukukhanya okungabonakaliyo kubandakanya ukukhanya kwe-ultraviolet kunye nokukhanya kwe-infrared.Iiyunithi zeFotoometry kunye ne-colorimetry zisetyenziselwa ukulinganisa iimpawu zokukhanya.Ukukhanya kuneempawu zobungakanani kunye nekhwalithi.Owokuqala bubunzima bokukhanya kunye ne-photoperiod, kwaye le yokugqibela ngumgangatho wokukhanya okanye ukuhanjiswa kwamandla okukhanya kwe-harmonic.Kwangaxeshanye, ukukhanya kuneepropati zamasuntswana kunye neempawu zamaza, oko kukuthi, ubumbini besuntswana lamaza.Ukukhanya kuneempawu ezibonakalayo kunye neempawu zamandla.Iindlela zokulinganisa ezisisiseko kwi-photometry kunye ne-colorimetry.① Ukukhanya okukhanyayo, iyunithi yelumens lm, ibhekisa kwisimbuku somthamo wokukhanya okhutshwa ngumzimba okhanyayo okanye umthombo wokukhanya ngexesha leyunithi, oko kukuthi, ukukhanya okukhanyayo.② Ubunzulu bokukhanya: isimboli I, iyunithi yecandela cd, ukukhanya okukhanyayo okukhutshwa ngumzimba okhanyayo okanye umthombo wokukhanya ngaphakathi kwe-engile enye eqinileyo kwicala elithile.③Illuminance: Uphawu E, iyunithi lux lm/m2, ukukhanya okukhanyayo okukhanyiswa ngumzimba okhanyayo kwindawo yeyunithi yento ekhanyisiweyo.④Ukukhanya: Uphawu L, iyunithi ye-Nitr, i-cd/m2, i-flux ekhanyayo yento ekhanyayo kwicala elithile, iyunithi ye-angle eqinile, indawo yeyunithi.⑤Ukusebenza okukhanyayo: Iyunithi yilumens ngewathi, lm/W.Ukukwazi komthombo wokukhanya kombane ukuguqula amandla ombane abe kukukhanya kubonakaliswa ngokwahlula i-flux ekhanyayo ngokusetyenziswa kwamandla.⑥Ukuphumelela kwesibane: Ikwabizwa ngokuba yi-coefficient yemveliso yokukhanya, ngumgangatho obalulekileyo wokulinganisa amandla ezibane.Ingumlinganiselo phakathi kokukhanya kwamandla okukhanya ngesibane kunye nokukhanya kwamandla aphuma ngumthombo wokukhanya ngaphakathi kwesibane.⑦ Umndilili wobomi: iyure yeyunithi, ibhekisa kwinani leeyure xa i-50% yebhetshi yebhalbhu yonakalisiwe.⑧ Ubomi bezoqoqosho: iyure yeyunithi, kuthathelwa ingqalelo umonakalo wesibane kunye nokuthotywa kwemveliso ye-beam, imveliso ye-boam ebanzi iyancipha ukuya kwinani elithile leeyure.Lo mlinganiselo yi-70% yemithombo yokukhanya yangaphandle kunye ne-80% yemithombo yokukhanya yangaphakathi efana nezibane ze-fluorescent.⑨ Ubushushu bombala: Xa umbala wokukhanya okhutshwa ngumthombo wokukhanya ufana nombala wokukhanya okhutshwa ngumzimba omnyama kwiqondo elithile lobushushu, ubushushu bomzimba omnyama bubizwa ngokuba bubushushu bombala bomthombo wokukhanya.Ubushushu bombala bomthombo wokukhanya buhlukile, kwaye umbala okhanyayo nawo uhlukile.Ubushushu bombala obungaphantsi kwe-3300K bunomoya ozinzile kunye nokufudumala;ubushushu bombala phakathi kwe-3000 kunye ne-5000K bubushushu bombala obuphakathi, obunomvakalelo ohlaziyayo;ubushushu bombala obungaphezulu kwe-5000K bunemvakalelo ebandayo.⑩ Ubushushu bombala kunye nonikezelo lombala: Unikezelo lombala womthombo wokukhanya lubonakaliswa sisalathiso sombala, esibonisa ukuba ukutenxa kombala wento ephantsi kokukhanya xa kuthelekiswa nombala wesikhanyiso sokukhanya (ukukhanya kwelanga) kunokubonakalisa ngakumbi iimpawu zombala. yomthombo wokukhanya.
Ukulungiswa kwexesha lokukhanya lokuzalisa
1. Njengokukhanya okongeziweyo, kunokwandisa ukukhanya nangaliphi na ixesha lemini kwaye kwandise ixesha lokukhanyisa elisebenzayo.
2. Nokuba kurhatyela okanye ebusuku, inokwandisa ngokufanelekileyo kwaye ilawule ngokwenzululwazi ukukhanya okufunwa zizityalo.
3. Kwiindawo zokugcina izityalo okanye iilebhu zezityalo, zinokutshintsha ngokupheleleyo ukukhanya kwendalo kunye nokukhuthaza ukukhula kwezityalo.
4. Sombulula ngokupheleleyo imeko yokuxhomekeka kwimozulu ngexesha lokukhula kwezithole, kwaye ucwangcise ixesha ngokufanelekileyo ngokomhla wokuziswa kwezithole.
Ukukhanya kokukhula kwezityaloukhetho
Kuphela ngokukhetha imithombo yokukhanya ngokwenzululwazi singakwazi ukulawula ngcono isantya kunye nomgangatho wokukhula kwezityalo.Xa usebenzisa imithombo yokukhanya eyenziweyo, kufuneka sikhethe ukukhanya kwendalo okukufutshane ukuhlangabezana neemeko ze-photosynthesis zezityalo.Ukulinganisa ukukhanya kwe-photosynthetic flux density PPFD (Photosynthetic PhotonFlux Density) eveliswe ngumthombo wokukhanya kwisityalo ukuze ubambe ireyithi yephotosynthesis yesityalo kunye nokusebenza kakuhle komthombo wokukhanya.Isixa seefotoni ezisebenza ngephotosynthetically ziqalisa iphotosynthesis yesityalo kwikloroplast: kubandakanywa ukusabela kokukhanya kunye nokusabela okumnyama okulandelayo.
Izibane zokukhula kwezityalokufuneka ibe nezi mpawu zilandelayo
1. Guqula amandla ombane abe ngamandla akhazimlayo ngokufanelekileyo.
2. Ukuzuza ubunzulu bemitha yemitha phakathi koluhlu olusebenzayo lwephotosynthesis, ngakumbi imitha ye-infrared ephantsi (imitha ye-thermal)
3. I-radiation spectrum yebhalbhu yokukhanya ihlangabezana neemfuno zefiziyoloji yezityalo, ngakumbi kwingingqi ye-spectral esebenzayo ye-photosynthesis.
Umgaqo wesityalo sokuzalisa ukukhanya
Isityalo se-LED sizalise ukukhanya luhlobo lweisibane sesityalo.Isebenzisa ukukhanya-emitting diodes (LEDs) njengomthombo wokukhanya kwaye isebenzisa ukukhanya endaweni yokukhanya kwelanga ukudala indawo yokukhula kwezityalo kunye nophuhliso ngokwemithetho yokukhula kwezityalo.Izibane zezityalo ze-LED zinceda ukunciphisa umjikelo wokukhula kwezityalo.Umthombo wokukhanya uqulunqwe ikakhulu yimithombo yokukhanya ebomvu nebhlowu.Isebenzisa eyona bhanti yokukhanya ebuthathaka yezityalo.I-wavelength yokukhanya okubomvu isebenzisa i-630nm kunye ne-640 ~ 660nm, kunye ne-blue light wavelength isebenzisa i-450 ~ 460nm kunye ne-460 ~ 470nm.Le mithombo yokukhanya inokuvumela izityalo ukuba zivelise i-photosynthesis efanelekileyo, evumela ukuba izityalo zikhule ngokufanelekileyo.Ukukhanya okusingqongileyo yenye yezinto ezibalulekileyo zokusingqongileyo eziyimfuneko ekukhuleni nasekuphuhliseni izityalo.Ukulawula i-morphology yezityalo ngohlengahlengiso lomgangatho wokukhanya yitekhnoloji ebalulekileyo kwintsimi yokulima indawo.
