Ib, qhov teeb meem nrog lub teeb pom kev zoo yog tias nws siv ntau lub zog, tsis muab lub teeb pom kev zoo, thiab tsim kom muaj cua sov ntau.
High -Siab Sodium Teeb (HPS) thiab fluorescent teeb yog hom teeb pom kev zoo siv hauv tsev cog khoom. Txawm li cas los xij, cov teeb pom kev zoo no muaj peb qhov teeb meem loj:
Tsis muaj zog npaum li cas: HPS teeb tsuas yog hloov ib ncig ntawm 30% ntawm cov hluav taws xob hluav taws xob uas lawv siv rau hauv lub teeb pom kev. Cov seem ntawm lub zog yog hloov mus rau hauv tshav kub. Piv txwv li, hauv Shouguang City, lub tsev cog khoom ib txwm xav tau ntxiv 30% ntawm hluav taws xob kom txias thaum lub caij ntuj no thaum lub teeb ci, uas ua rau tag nrho cov nqi siv hluav taws xob los ntawm 45%.
Nws tsis muaj peev xwm tswj tau qhov spectrum: fluorescent teeb muaj qhov ruaj khov spectrum uas tsis ua haujlwm rau txhua theem ntawm cov nroj tsuag loj hlob. Piv txwv li, lub teeb xiav yog xav tau los pab cov txiv lws suav loj hlob hauv paus, thiab lub teeb liab yog xav tau los pab paj buds loj hlob thaum lub sij hawm flowering. Kev hloov kho dynamic tsis tuaj yeem ua tau nrog cov teeb pom kev zoo ib txwm muaj.
Cov hluav taws xob hluav taws xob cuam tshuam: HPS teeb tuaj yeem kub dua 200 degrees Celsius ntawm lawv qhov chaw, uas tuaj yeem nce qhov kub hauv tsev cog khoom los ntawm 5 txog 8 degrees Celsius. Qhov no ua rau nws tsim nyog rau cov neeg ua liaj ua teb yuav tsum qhib cov cuab yeej ua pa ntau zaus, uas ua rau lub zog ntau dua.
2, LED cog teeb yog ib kauj ruam loj rau hauv kev siv tshuab vim lawv cia koj tswj lub teeb kom meej thiab txuag zog.
LED thev naus laus zis tam sim no paub tab txaus los ua kev ua si - hloov pauv rau kev ua liaj ua teb tsev cog khoom. Nws cov txiaj ntsig tseem ceeb tau qhia hauv cov hauv qab no:
1. Customizing lub spectrum: mus los ntawm "ib qhov loj haum rau txhua qhov" mus rau "ntawm-xov khoom" Cov nroj tsuag photosynthesis feem ntau yog nyob ntawm lub teeb liab (630–660nm) thiab lub teeb xiav (450–470nm), txawm li cas los xij, ntau yam qoob loo thiab theem kev loj hlob muaj qhov sib txawv spectral xav tau heev. Piv txwv li:
Rau cov nplooj ntsuab zoo li lettuce, biomass yog siab tshaj thaum qhov liab rau xiav piv yog 7: 3. Lub teeb xiav ntau dhau tuaj yeem ua rau lawv loj hlob sai heev;
Solanaceous txiv hmab txiv ntoo, zoo li txiv lws suav, xav tau ntau tshaj 60% lub teeb liab thaum lub caij fruiting los pab cov txiv hmab txiv ntoo loj hlob. Ntxiv lub teeb liab nyob deb (730nm) kuj tseem tuaj yeem pab cuam tshuam cov kev txwv photoperiod thiab tso cai rau tawm - caij nyoog tsim tawm . -Cov nroj tsuag tshuaj zoo li perilla tuaj yeem ua rau ntau cov anthocyanins thaum raug UV LED lub teeb (385nm), uas ua rau kom cov tshuaj nquag ntxiv los ntawm 35%.
Lub "Adjustable Spectral LED Tissue Culture Teeb" ua los ntawm Nanjing Agricultural University hloov pauv liab -xiav piv rau lub sijhawm siv huab cua. Qhov no nce qhov zoo ntawm Phalaenopsis cov ntaub so ntswg kab lis kev cai seedlings ntawm 68% mus rau 92% thiab txiav lub voj voog ntawm 40%.
2. Txuag lub zog thiab ua kom muaj txiaj ntsig zoo: hloov ntawm "kev siv siab thiab kev ua haujlwm qis" mus rau "ntsuab thiab qis-carbon."
LEDs tuaj yeem hloov 40-50% ntawm lub teeb uas lawv tau txais rau hauv hluav taws xob, uas yog ntau dua 50% tsawg zog dua li HPS teeb. Ntuj Greens ntsug ua liaj ua teb hauv Singapore siv LED ntau- txheej txheej cog. Nws tsim tau 100 npaug ntau dua cov zaub mov hauv ib cheeb tsam dua li cov chaw ua liaj ua teb, tab sis nws tsuas yog siv ib feem peb ntawm lub zog. Cov khoom siv hluav taws xob qis ntawm LEDs yog qhov tseem ceeb tshaj vim tias lawv txwv qhov kub hauv tsev cog khoom los ntawm kev hloov ntau dua 2 degrees Celsius, uas txhais tau hais tias cov cua txias tsis tas yuav tsum tau siv ntau zaus, uas yuav txuag tau ntau lub zog.
Zaj dab neeg ntawm Songjia Daozhuang nyob rau hauv Daotian lub zos, Shouguang City yog ntau persuasive. Ib tug neeg ua liaj ua teb tau hloov los ntawm HPS lub teeb qub rau LED teeb pom kev zoo, uas txiav cov hluav taws xob txhua xyoo ntawm ib lub tsev cog khoom los ntawm 12000 kWh mus rau 6000 kWh. Cov nyiaj tau los txhua xyoo ntawm ib lub tsev xog paj tau nce 25% txij li cov tshuaj tua kab tsawg tau siv (LED spectra tuaj yeem nres qee yam kab mob).
3. Qhov chaw optimisation: los ntawm "paj cog" mus rau "peb-dav hlau Hoobkas"
LED teeb yog qhov zoo rau kev ua liaj ua teb ntsug vim tias lawv nyias (tsuas yog 3-5 cm tuab) thiab tsis txhob tso cua sov ntau. Ntawm Yuntai Farm nyob rau hauv Lianyungang, lub ntse kab lis kev cai chamber rau Phalaenopsis muaj LED teeb strips saum toj no txhua cultivation khib. Qhov sib txawv ntawm cov khaubncaws sab nraud povtseg tau raug txiav los ntawm 1.5 meters mus rau 0.8 meters, uas tau nce qhov chaw siv los ntawm 47%. Cov cuab yeej tuaj yeem hloov qhov siv lub teeb (0–2000 μ mol / m² / s) thiab spectral piv thaum siv nrog IoT sensors. Qhov no ua rau luv luv lub voj voog ntawm Phalaenopsis los ntawm 15 hnub thiab ua rau cov xim ntawm cov nplaim paj ntau dua li 30%.
3, Lub ntsiab lus tseem ceeb ntawm kev txhim kho kev lag luam: kev sib cuam tshuam ntawm cov cai, kev lag luam, thiab thev naus laus zis
Kev siv dav ntawm LED cog teeb tsis yog tsuas yog vim kev txhim kho hauv kev siv thev naus laus zis, tab sis kuj tseem yog tsoomfwv txoj cai, kev xav tau ntawm kev lag luam, thiab kev noj qab haus huv ntawm kev lag luam tag nrho.
1. Txoj cai faib nyiaj: los ntawm "subsidy driven" mus rau "tus qauv coj"
Ministry of Agriculture thiab Rural Affairs ntawm Tuam Tshoj "14th Tsib Xyoo Plan rau National Agricultural Green Development" hais tias los ntawm 2025, 60% ntawm cov chaw ua liaj ua teb yuav tsum tau siv teeb pom kev zoo LED. Lub tswv yim "khoom plig tsis yog nyiaj pab" yog siv los ntawm tsoomfwv hauv nroog los txhawb kev siv thev naus laus zis. Piv txwv li, Shandong xeev muab cov tsev cog khoom uas siv LED sau lub teeb qhov nyiaj pab ntawm 2000 yuan ib mu thiab teeb tsa cov txheej txheem rau spectral regulating technology.
2. Kev lag luam xav tau: los ntawm "kev tsim khoom ua ntej" mus rau "zoo yog huab tais"
Kev lag luam xav tau rau siab - cov zaub mov kawg, cov nroj tsuag tshuaj, thiab paj zoo nkauj nthuav dav los ntawm qhov nruab nrab ntawm 12% ib xyoos twg thaum tib neeg pib yuav khoom kim dua. LED spectrum tswj thev naus laus zis tuaj yeem tswj hwm cov qoob loo morphology (piv txwv li, thickening nplooj zaub), cov khoom noj khoom haus (xws li txhawb cov vitamin C hauv cov txiv lws suav los ntawm 20%), thiab cov tshuaj tsw qab (xws li optimizing cov suab thaj -acid ratio hauv strawberries), catering rau cov kev cai tshwj xeeb.
3. Industrial Ecology: Los ntawm "Single Point Breakthrough" mus rau "System Integration"
LED cog teeb ua haujlwm zoo nrog Internet ntawm Yam, cov ntaub ntawv loj, thiab kev txawj ntse. Piv txwv li, Philips 'GrowWise tswj qhov system hauv Netherlands tuaj yeem tsim cov phiaj xwm teeb pom kev zoo raws li cov qauv ntawm cov qoob loo loj hlob thiab tso cai rau kev saib xyuas thaj chaw deb ntawm 5G tes hauj lwm. Tuam Tshoj KeRui Microchip's "Smart Light Ib puag ncig Platform" sib txuas cov ntaub ntawv xws li spectrum, kub, av noo, thiab CO₂ qib los tsim qhov kaw - voj tswj qhov system uas txhawb nqa tsev cog khoom ua haujlwm tau zoo los ntawm 18%.
