DLI yog dab tsi?
DLI (Daily Light Integral), yog tus nqi ntawm PAR (Photosynthetically Active Radiation tus kheej cov khoom ntawm lub teeb nyob rau hauv 400-700 nm ntau), tau txais txhua hnub raws li kev ua haujlwm ntawm lub teeb siv thiab lub sijhawm.Nws yog qhia nyob rau hauv cov nqe lus ntawm mol / m2/ d (moles ntawm lub teeb ib square meter ib hnub twg).
Qhov kev ntsuas no yog qhov tseem ceeb vim tias qhov pom ntawm koj cov nroj tsuag tau txais hauv ib hnub ncaj qha rau cov nroj tsuag kev loj hlob, kev loj hlob, tawm los, thiab qoob loo zoo.
DLI ntau npaum li cas cov qoob loo sab hauv tsev xav tau?
Cia wb mus saib DLI qhov yuav tsum tau muaj ntawm ntau cov qoob loo uas nrov tshaj plaws hauv tsev.
| Nroj tsuag | DLI Requirement |
| Tsob Ntoo Tsob Ntoo | 6–10 |
| Peas | 9 |
| Basil | 12 |
| Broccoli | 15-35 : kuv |
| Txiv lws suav | 20-30 |
| Zucchini | 25 |
| Kua txob | 30-40 |
| Cannabis | 30-45 : kuv |
Peb tuaj yeem nrhiav Peppers thiab Cannabis muaj qhov xav tsis thoob qhov xav tau DLI siab, uas yog vim li cassiab PPF tso zis teebyog ib qho tseem ceeb thaum cog cov qoob loo hauv tsev.
Kev sib raug zoo ntawm PPFD thiab DLI yog dab tsi?
Cov mis rau xam DLI yog: μmol m-2s-1 (los yog PPFD) x (3600 x photoperiod) / 1,000,000 = DLI (los yog moles / m2 / hnub)
PPFD yog tus naj npawb ntawm photons uas tuaj txog ntawm thaj chaw tshwj xeeb (m2) txhua ob, ntsuas hauv micromoles (μmol m-2s-1).
1.000.000 micromoles = 1 mole
3600 vib nas this = 1 teev
