Koj siv ntau lub teeb loj hlob tab sis koj cov nroj tsuag tseem Leggy thiab yuav tsis paj? Dab tsi yog "Invisible Wavelength" Koj tau saib dhau?
Ntau tus neeg cog qoob loo hauv tsev siv ntau pua ntawm qhov hu ua "cov teeb pom kev tshwj xeeb", tsuas yog nrhiav cov succulents tig mus rau hauv taum sprouts thiab txiv lws suav loj hlob nplooj tab sis tsis muaj txiv hmab txiv ntoo. Feem ntau qhov teeb meem tsis yog qhov kaj - nws yog qhov spectrum tsis muaj ob peb qhov tseem ceeb "tsis pom wavelengths".
1. Cwj Pwm: Liab + Xiav Ib Leeg txhais tau tias "Malnourished" cog
Nroj tsuag siv lub teeb nyob rau hauv ob txoj kev loj:
- Photosynthesis(tsuas yog liab thiab xiav, tab sis ntsuab kuj pab txhawb)
- Photomorphogenesis(dawb-liab, UV, thiab lwm yam. tswj cov nroj tsuag zoo, flowering, kev nyuaj siab tsis kam)
Yog hais tias lub teeb spectrumTsuas muaj ob lub ncov ntawm 450nm thiab 660nm, ces:
- Cov nplooj qis tau txais lub teeb ntsuab tsis txaus nkag mus → photosynthetic efficiency poob30‑50%
- Tsis muaj lub teeb liab (700-780nm) → paj induction lub sij hawm ncua los ntawm2-4 lub lis piam
- Excessive blue light proportion (>40%) → tshaj-inhibition ntawm qia elongation, ua rau cov nroj tsuag stunted thiab txo cov nplooj
Qhov tseeb tag nrho spectrum yog txhais raws linruam 380-780nm tsis muaj qhov khoob, thiab qhov kev faib ua feem ntawm deb-liab txheeb ze rau liab yuav tsum nyob ze ntawm lub hnub ci ntuj:R: FR ≈ 1.0-1.3.
2. Khoom tawg: Cov ntaub ntawv tseem ceeb ntawm Benwei Full-Spectrum PAR38
Cov khoom no tsis yog ib qho yooj yim "liab + ntsuab + xiav" patchwork. Es tsis txhob, dhaumulti-band phosphors + cov chips tshwj xeeb, nws ua tiav cov txiaj ntsig ntsuas hauv qab no (raws li 30W qauv, kev sib koom ua ke cov ntaub ntawv):
Spectral Key Indicators
| Band | Wavelength ntau yam (nm) | Photon ratio (%) | Muaj nuj nqi |
|---|---|---|---|
| UV / Violet | 380-420 | 2-3 | Txhawb nqa cov metabolism hauv theem nrab (anthocyanins, tsw tebchaw) |
| Xiav | 420-500 | 22-25 | Inhibits ncab, stomatal tswj |
| Ntsuab | 500-600 | 30-35 | Canopy nkag mus, nce photosynthesis ntawm nplooj qis los ntawm +40% |
| Liab | 600-700 | 30-35 | Lub ntsiab photosynthetic zog qhov chaw |
| Far-liab | 700-780 | 8-12 | Induces paj, shortens internodes |
Core spectral parameters:
- R: FR= 1.2 (simulates qhov piv ntawm hnub ci ntxoov ntxoo)
- Xiav lub teeb proportions= 24% (qhov chaw nyab xeeb:<30%)
- Spectral txuas ntxiv = no drop >15% ntawm 50nm ncua sijhawm
Kev ua haujlwm photoelectric (@25 degree, AC 120V / 230V)
| Parameter | Tus nqi |
|---|---|
| Hwj chim | 15W / 30W / 50W yeem |
| PPF (Photosynthetic Photon Flux) | 24 μmol / s (15W) / 48 μmol / s (30W) / 75 μmol / s (50W) |
| Kev ua tau zoo | 1.6 μmol / J |
| PPFD @ 30cm (centre) | 320 μmol·m⁻²·s⁻¹ (30W) |
| Beam lub kaum sab xis | 90℃/ 120 degree |
| Lub neej ntev L70 | 50,000 h |
| Kub dab dej kub (25℃ambient) | Tsawg dua lossis sib npaug li 65 degree |
| Fais fab xwm txheej | >0.9 |
PPFDyog tus naj npawb ntawm photons ib cheeb tsam ib chav tsev ib lub sij hawm - nws ncaj qha txiav txim siab tus nqi photosynthetic. Cov nplooj ntoo xav tau 150-300, paj / txiv hmab txiv ntoo 300-500, cov noob 100-150. Tus qauv 30W saum toj no muab 320 ntawm 30cm, ua tau raws li cov kev xav tau ntawm cov txiv lws suav thiab kua txob thaum lub sij hawm flowering thiab fruiting.
3. Cov ntaub ntawv sib piv: Vim li cas cov kev daws teeb meem ib txwm poob ntawm tus lej
| Cov khoom sib piv | Liab + Xiav LED teeb | Ordinary dawb LED teeb | Benwei tag nrho-spectrum PAR38 |
|---|---|---|---|
| Spectral txuas ntxiv (%) | 15% (tsuas yog ob lub ncov) | 70% (tsis muaj xim liab) | 98% |
| PPF @ 15W (μmol / s) | 18 | 10 | 24 |
| Kev ua tau zoo (μmol / J) | 1.2 | 0.67 | 1.6 |
| Far-red ratio (%) | 0 | 0 | 10 |
| Lub teeb ntsuab piv (%) | 0-5 | 40 | 32 |
| Xiav lub teeb piv (%) | 45 | 38 | 24 |
| Lub neej ntev (h) | 25,000 | 10,000 | 50,000 |
| PPFD ntawm 50cm (μmol·m⁻²·s⁻¹) | 85 | 45 | 140 |
| Yuav siv tau li chav teeb pom kev zoo? | Tsis yog (hmoov liab) | Yog (tab sis txias dawb) | Yes (warm white, CRI>90) |
Kev txhais cov ntaub ntawv:
PPF 33% siab dua: ntawm tib 15W, tag nrho spectrum tsim 6 μmol / s ntau photons dua li lub teeb liab + xiav - kwv yees li 20% ntau lub teeb lub zog ib hnub.
10% dhau-liabmuaj peev xwm ua ntej flowering ntawm ntev-hnub nroj tsuag (xws li, lettuce, spinach) los ntawm7-10 hnub.
32% lub teeb ntsuabnce lub teeb tau txais los ntawm cov nplooj qis los ntawm 40%, nce tag nrho cov nroj tsuag photosynthetic efficiency los ntawm 15-20%.
4. Kev siv cov xwm txheej thiab cov phiaj xwm teeb pom kev zoo
| Hom qoob loo | Hanging qhov siab (cm) | Lub sijhawm lub teeb ci txhua hnub (h) | DLI (mol·m⁻²·d⁻¹) | Cia siab tias yuav tshwm sim |
|---|---|---|---|---|
| Nplooj ntsuab ( lettuce, spinach) | 30-40 | 12-14 | 12-15 | Sau nyob rau hauv 20-25 hnub, tuab nplooj tsaus |
| Tshuaj ntsuab (basil, mint) | 30-50 | 14-16 | 15-20 | Luv internodes, muaj zog aroma |
| Flowering nroj tsuag (kalanchoe, petunia) | 25-35 | 12-14 + hmo ntuj cuam tshuam | 10-12 | Paj bud sib txawv 2 lub lis piam ua ntej |
| Succulents (Echeveria) | 20-30 | 10-12 | 8-10 | Clear colouring, tsis muaj stretching |
| Txiv lws suav / kua txob (yeem theem) | 40-50 | 16 | 12-15 | Cov stems tuab, tsis muaj leggy seedlings |
DLI (Daily Light Integral)= PPFD × vib nas this ntawm lub teeb / 1,000,000. A DLI qis dua 8 txo cov qoob loo rau feem ntau txiv hmab txiv ntoo thiab zaub; saum 20 yuav ua rau photoinhibition.
5. Peb Txoj Cai Ua Tus lej rau Kev Xaiv Ib Daim Ntawv Qhia Tag Nrho PAR38
- Nug rau spectrum graph- Tshawb xyuas lub teeb xiav qhov piv txwv tsawg dua lossis sib npaug li 30%, thiab muaj qhov siab pom tseeb hauv cov kab liab liab (700-780nm).
- Xam kev ua tau zoo: PPF (W) ÷ lub zog (W) Ntau dua lossis sib npaug rau 1.5 μmol / J- Cov nqi qis dua qhia tias tsis zoo phosphor lossis chip efficiency.
- Kub dab dej hnyav Ntau dua los yog sib npaug rau 150g (rau 30W qauv) – aluminium thermal conductivity >150 W / m·K, ua kom lub tsev kub tsis tshaj 70 degree.
6. Cov lus xaus
Lub hauv paus ntawm cov nroj tsuag loj hlob lub teeb tsis yog "ci", tab sis "spectral match + photon kom muaj nuj nqis". Nrog kev ua tau zoo ntawm1.6 μmol / J, balanced ratio ntawm24% xiav + 10% far-liab, thiab a50,000 teevlifespan, Benwei full-spectrum PAR38 muab cov ntaub ntawv-tsav kev daws teeb meem ze rau ntuj tshav ntuj. Siv lub teeb tsis nyob hauv cov rooj saum toj no, koj tuaj yeem xam raws nraim pes tsawg lub teeb koj cov nroj tsuag xav tau, qhov siab npaum li cas, thiab ntev npaum li cas.
