Thaum lub caij los nag los, hnub ci tau dhau los ua qhov tsis tshua muaj.
Rau cov neeg nyiam kev loj hlob succulents lossis succulent cog, nws tuaj yeem hais tias ntxhov siab.
Succulents nyiam lub hnub ci thiab nyiam qhov chaw muaj cua.Qhov tsis muaj qhov kaj yuav ua rau lawv nyias thiab siab, ua rau lawv tsis zoo.Qhov cua tsis txaus tuaj yeem ua rau lawv cov hauv paus hniav lwj, thiab cov nqaij tawv tuaj yeem wilt los yog tuag.
Ntau tus phooj ywg uas loj hlob succulents xaiv siv cov teeb pom kev zoo los sau cov succulents.
Yog li, yuav ua li cas xaiv lub teeb puv?
Cia peb nkag siab txog qhov cuam tshuam ntawm qhov sib txawv wavelengths ntawm lub teeb ntawm cov nroj tsuag:
280 ~ 315nm: cuam tshuam tsawg kawg nkaus ntawm morphology thiab physiological txheej txheem;
315 ~ 400nm: Tsawg nqus ntawm chlorophyll, uas cuam tshuam cov nyhuv photoperiod thiab tiv thaiv qia elongation;
400 ~ 520nm (xiav): Qhov sib piv ntawm chlorophyll thiab carotenoids yog qhov loj tshaj plaws, thiab muaj kev cuam tshuam loj tshaj plaws ntawm photosynthesis;
520 ~ 610nm (ntsuab): tus nqi nqus ntawm cov xim tsis siab;
610 ~ 720nm (liab): Tsawg chlorophyll nqus tus nqi, uas muaj kev cuam tshuam tseem ceeb ntawm photosynthesis thiab photoperiod teebmeem;
720 ~ 1000nm: Tsawg nqus tus nqi, txhawb nqa cell elongation, cuam tshuam rau paj thiab noob germination;
＞1000nm: Hloov mus rau hauv tshav kub.
Ntau tus phooj ywg tau yuav txhua yam hu ua cov teeb pom kev loj hlob hauv Is Taws Nem, thiab qee tus hais tias lawv muaj txiaj ntsig zoo tom qab siv lawv, thiab qee tus hais tias lawv tsis muaj txiaj ntsig.Qhov xwm txheej tiag tiag yog dab tsi?Koj lub teeb tsis ua haujlwm, tej zaum yog vim koj yuav lub teeb tsis raug.
Qhov txawv ntawm cov teeb pom kev loj hlob thiab cov teeb pom kev zoo tib yam:
Daim duab qhia tag nrho pom lub teeb spectrum (hnub ci).Nws tuaj yeem pom tau tias cov nthwv dej uas tuaj yeem txhawb nqa kev loj hlob ntawm cov nroj tsuag yog qhov ncaj ncees rau xim liab thiab xiav, uas yog thaj chaw uas muaj kab ntsuab hauv daim duab.Qhov no yog vim li cas thiaj li hu ua LED cog kev loj hlob teeb yuav hauv online siv liab thiab xiav teeb hlaws.
Kawm paub ntau ntxiv txog cov yam ntxwv thiab kev ua haujlwm ntawm LED cog teeb:
1. Qhov sib txawv wavelengths ntawm lub teeb muaj qhov sib txawv ntawm cov nroj tsuag photosynthesis.Lub teeb xav tau rau cov nroj tsuag photosynthesis muaj lub wavelength ntawm 400-700nm.400-500nm (xiav) lub teeb thiab 610-720nm (liab) pab txhawb rau photosynthesis.
2. Xiav (470nm) thiab liab (630nm) LEDs tsuas yog muab lub teeb uas xav tau los ntawm cov nroj tsuag, yog li qhov kev xaiv zoo tshaj plaws yog siv ob qho xim sib xyaw ua ke.Nyob rau hauv cov nqe lus ntawm kev pom kev, lub teeb liab thiab xiav nroj tsuag yog liab.
3. Lub teeb xiav pab cov nroj tsuag photosynthesis, uas tuaj yeem txhawb cov nplooj ntsuab loj hlob, protein synthesis, thiab tsim cov txiv hmab txiv ntoo;Lub teeb liab tuaj yeem txhawb cov nroj tsuag rhizome kev loj hlob, pab flowering thiab fruiting thiab prolong flowering, thiab nce yield!
4. Qhov piv ntawm liab thiab xiav LEDs ntawm LED cog teeb yog feem ntau ntawm 4: 1--9: 1, feem ntau 6-9: 1.
5. Thaum cov teeb pom kev zoo siv los ntxiv lub teeb rau cov nroj tsuag, qhov siab ntawm nplooj feem ntau yog li ntawm 0.5-1 meters, thiab txuas ntxiv raug rau 12-16 teev ib hnub twg tuaj yeem hloov lub hnub tag nrho.
6. Cov nyhuv tseem ceeb heev, thiab qhov kev loj hlob yuav luag 3 npaug sai dua li cov nroj tsuag zoo tib yam uas loj hlob ib txwm muaj.
7. daws qhov teeb meem ntawm qhov tsis muaj hnub ci thaum lub caij los nag lossis hauv tsev cog khoom thaum lub caij ntuj no, thiab txhawb cov chlorophyll, anthocyanin thiab carotene xav tau hauv cov nroj tsuag photosynthesis, kom cov txiv hmab txiv ntoo thiab zaub tau sau 20% ua ntej, nce cov qoob loo los ntawm 3 mus rau 50%, thiab ntau dua.Qhov qab zib ntawm txiv hmab txiv ntoo thiab zaub txo cov kab tsuag thiab kab mob.
8. LED teeb qhov chaw tseem hu ua semiconductor lub teeb ci.Qhov zoo ntawm lub teeb ci no muaj qhov nqaim nqaim thiab tuaj yeem tawm lub teeb ntawm ib lub wavelength tshwj xeeb, yog li cov xim ntawm lub teeb tuaj yeem tswj tau.Siv nws rau irradiate nroj tsuag ib leeg tuaj yeem txhim kho cov nroj tsuag ntau yam.
9. LED cog kev loj hlob teeb muaj lub zog tsawg tab sis tsis tshua muaj kev ua haujlwm siab, vim tias lwm lub teeb emit ib tug tag nrho spectrum, uas yog hais tias, muaj 7 xim, tab sis dab tsi nroj tsuag xav tau yog lub teeb liab thiab xiav, yog li feem ntau ntawm lub teeb lub zog ntawm tsoos teeb yog khib, yog li ntawd cov efficiency yog tsawg heev.LED cog kev loj hlob teeb tuaj yeem tso tawm lub teeb liab thiab xiav tshwj xeeb uas cov nroj tsuag xav tau, yog li qhov ua tau zoo heev.Qhov no yog vim li cas lub hwj chim ntawm ob peb watts ntawm LED cog kev loj hlob teeb yog zoo dua li lub teeb nrog lub hwj chim ntawm kaum tawm watts los yog txawm pua pua ntawm watts.
Lwm qhov laj thawj yog qhov tsis muaj lub teeb xiav nyob rau hauv spectrum ntawm tsoos sodium teeb, thiab tsis muaj lub teeb liab nyob rau hauv lub spectrum ntawm mercury teeb thiab lub zog txuag teeb.Yog li ntawd, cov teeb pom kev zoo ntxiv ntawm cov teeb pom kev zoo yog qhov phem dua li cov teeb ci LED, thiab nws txuag tau ntau dua 90% ntawm lub zog piv nrog cov teeb pom kev zoo.Tus nqi txo qis heev.
