Vim li cas Koj Pitaya Yield Tsawg? - Yuav ua li cas LED loj hlob teeb tuaj yeem nce ntau lawm ntau dua 80%
Nyob rau sab qaum teb hnub ci tsev cog khoom, pitaya feem ntau raug kev txom nyem los ntawm lub teeb tsis txaus, ua rau cov paj tsis zoo thiab cov txiv hmab txiv ntoo tsawg. Raws li ntev -hnub cog, pitaya yuav tsum tau ze li 12 teev ntawm nruab hnub nrig kom pib paj buds. Lub ntuj luv hnub nyob rau lub caij nplooj ntoos hlav thiab lub caij nplooj zeeg yog lub ntsiab bottleneck limiting yield.LED loj hlob teebmuab kev tshawb fawb, ua tau zoo, thiab tus nqi -kev daws teeb meem zoo.
1. LED Teeb: Tsis yog "Zoo dua yog qhov zoo dua" - Ua kom pom tseeb ntawm peb qhov tseem ceeb
Pitaya yog rhiab heev rau lub teeb zoo (wavelength). Cov xim sib txawv muaj qhov sib txawv heev. Hauv qab no yog cov kev ntsuas ntawm plaub lub teeb LED kuaj hauv txoj kev tshawb no:
| LED Code | Dominant Wavelength (nm) | Luminous Flux (Lm) | Lub zog (W) | Luminous efficiency (Lm / W) | Lub teeb yam ntxwv |
|---|---|---|---|---|---|
| L1 (pom zoo) | 596.1 | 1485.67 | 15 | 99.05 | Txiv kab ntxwv lub teeb, siab flux |
| L2 | 562.1 | 1439.01 | 15 | 95.93 | Daj -ntsuab |
| L3 | 699.9 | 851.79 | 9 | 94.64 | Lub teeb liab, lub zog qis tshaj |
| L4 | 582.3 | 1360.50 | 15 | 90.70 | Lub teeb daj |
| CK (tsis muaj ntxiv) | - | - | - | - | Lub teeb ntuj |
Cov ntsiab lus tseem ceeb:
- Kev ua tau zoo dua=txuag hluav taws xob ntau duaL1 muaj 99.05 Lm / W, muab ntau lub teeb rau ib watt.
- Dominant wavelength nyob ib ncig ntawm 590-600 nm (txiv kab ntxwv lub teeb) yog qhov zoo tshaj plawsrau txhawb flowering.
- Siab dua luminous flux ua kom muaj kev tiv thaiv zoo dua- L1 muaj qhov flux siab tshaj plaws.
2. Muaj pes tsawg txiv hmab txiv ntoo uas koj tuaj yeem tau txais nrog LED teeb pom kev zoo?
Qhov kev sim tau siv cov khoom lag luam zoo tshaj plaws"Israel Yellow Dragon (thornless yellow pitaya)". Cov ntaub ntawv los ntawm 4th flowering batch nyob rau hauv lub caij nplooj ntoos hlav yog piv rau hauv qab no:
| Kev kho LED | Txiv hmab txiv ntoo rau ib tsob nroj | Avg. Txiv hmab txiv ntoo hnyav (g) | Yield ib tsob nroj (kg) | Yield nce (%) |
|---|---|---|---|---|
| L1 | 7.37 | 382.93 | 2.82 | 80.85% |
| L2 | 7.32 | 381.24 | 2.79 | 80.64% |
| L3 | 6.40 | 370.50 | 2.37 | 77.22% |
| L4 | 7.31 | 374.95 | 2.74 | 80.29% |
| CK (tsis muaj teeb) | 1.40 | 385.15 | 0.54 | -- |
Qhov no txhais li cas:
- Txiv hmab txiv ntoo ib tsob ntoo ncelos ntawm 1.4 mus rau 7.37- ntau dua 5 ×.
- Yield nce mus txog80.85%- ib daim teb uas tsim tau 100 kg tam sim no ua tau tshaj 180 kg.
- Qhov nruab nrab cov txiv hmab txiv ntoo hnyav tsis poob, qhia tias lub teeb pom kev zoo txhawb cov paj buds yam tsis muaj txi txiv loj.
3. Caij nplooj ntoos hlav & caij nplooj zeeg teeb pom kev zoo: Kev sau qoob loo thaum ntxov + ncua sij hawm
| Lub caij | Lub Sijhawm Teeb Pom Kev | Teem caij txhua hnub | nyhuv |
|---|---|---|---|
| Caij nplooj ntoos hlav | Peb 2 – Apr 15 | 18:00 – 22:00 | Thawj flowering thaum ntxov li lub Peb Hlis, ntxiv4-5 txiv hmab txiv ntoo |
| Caij nplooj zeeg | Aug 15 – Oct 15 | 19:00 – 23:00 | Kawg flowering ncua mus rau lig Kaum ib hlis, ntxiv1-2 pawg |
Yog tsis muaj teeb pom kev ntxiv, thawj lub paj tawg paj tshwm sim thaum ntxov Lub Tsib Hlis. Nrog LED teeb pom kev zoo, paj pib thaum lub Peb Hlis lig -tshaj 40 hnub ua ntej, ntes tus nqi lag luam hwm.
4. Cov ntsiab lus qab zib puas poob? - Brix Cov ntaub ntawv yooj yim txhawj xeeb
Ntau tus txhawj xeeb tias cov qoob loo ntau dua tuaj yeem txo qhov qab zib. Txoj kev tshawb no ntsuas cov txiv hmab txiv ntoo Brix (tag nrho cov soluble solids, ≈ qab zib cov ntsiab lus × 0.8):
- Brix nrog LED teeb pom kev zoo:19.21% – 20.37%
- Brix tsis muaj teeb pom kev zoo: ~ 20.5% (me ntsis siab dua, tab sis tsis suav nrog qhov tseem ceeb)
Xaus: LED teeb pom kev zoo tsis cuam tshuam rau cov piam thaj ntau ntxiv. Kev hloov pauv me me yog vim muaj cov khoom noj khoom haus dilution los ntawm cov txiv hmab txiv ntoo ntau dua, uas tuaj yeem tswj tau nrog kev tsim nyog fertilization.
5. Cov lus pom zoo rau kev xaiv LED teeb
Raws li cov ntaub ntawv mus sib hais, cov neeg cog qoob loo yuav tsum ua qhov tseem ceeb:
- Lub teeb zoo: Dominant wavelength 590–600 nm (txiv kab ntxwv lub teeb) zoo tshaj - zoo li L1.
- Luminous efficiency Ntau dua los yog sib npaug rau 95 Lm / Wrau kev txuag hluav taws xob.
- Luminous flux Ntau dua lossis sib npaug li 1400 Lmlos xyuas kom meej tag nrho cov canopy coverage.
- Installation qhov siab: 80-100 cm saum toj no tsob ntoo canopy, nrog 1.5 m nrug ntawm teeb.
- Lub sijhawm teeb pom kev zoo: 4 teev nyob rau ib hnub - 18:00–22:00 nyob rau lub caij nplooj ntoos hlav, 19:00–23:00 lub caij nplooj zeeg.
Hauv ib kab lus: Xaiv lub teeb pom kev zoo LED, thiab koj lub pitaya tuaj yeem mus los ntawm "ob pawg hauv ib xyoos" mus rau "xya pob ib xyoos" - ob npaug koj cov txiaj ntsig tsis yog npau suav.
