DLI ke eng?
DLI(Daily Light Integral), ke palo ea PAR (Photosynthetically Active Radiation particles tsa khanya ka har'a 400-700 nm range), e amoheloang letsatsi ka leng e le ts'ebetso ea matla a khanya le nako.E hlalosoa ho latela mol/m2/d (li-moles tsa khanya ka square meter ka letsatsi).
Metric ena e bohlokoa hobane khanya eo limela tsa hau li e fumanang ka letsatsi e amana ka kotloloho le kholo ea semela, nts'etsopele, chai le boleng ba lijalo.
Lijalo tse tloaelehileng tsa ka tlung li hloka DLI e kae?
Ha re shebeng tlhoko ea DLI ea lijalo tse fapaneng tse lengoang ka tlung.
| Semela | Tlhokahalo ea DLI |
| Limela tsa Moriti | 6 - 10 |
| Lierekisi | 9 |
| Basil | 12 |
| Broccoli | 15-35 |
| Tamati | 20-30 |
| Zucchini | 25 |
| Pelepele | 30-40 |
| Cannabis | 30-45 |
Re ka fumana Peppers le Cannabis li na le tlhoko ea DLI e phahameng ka mokhoa o makatsang, ke ka lebaka leomabone a phahameng a tlhahiso ea PPFli bohlokoa ha u lema lijalo tsena ka tlung.
Kamano ke efe lipakeng tsa PPFD le DLI?
Foromo ea ho bala DLI ke: μmol m-2s-1 (kapa PPFD) x (3600 x photoperiod) / 1,000,000 = DLI (kapa moles/m2/letsatsi)
PPFD ke palo ea li-photon tse fihlang sebakeng se itseng (m2) motsotsoana o mong le o mong, tse lekantsoeng ka micromoles (μmol m-2s-1).
1.000.000 micromoles = 1 mole
3600 metsotsoana = 1 hora
