He aha ka DLI?
ʻO DLI (Daily Light Integral), ʻo ia ka nui o PAR (Photosynthetically Active Radiation i nā ʻāpana o ka mālamalama i ka laulā 400-700 nm), i loaʻa i kēlā me kēia lā ma ke ʻano he hana o ka māmā a me ka lōʻihi.Hōʻike ʻia ma ke ʻano o ka mol/m2/ d (mole o ka malamalama no ka mika square no ka la).
He mea koʻikoʻi kēia metric no ka mea ʻo ka nui o ka mālamalama i loaʻa i kāu mau mea kanu i ka lā e pili pono ana i ka ulu ʻana o ka mea kanu, ka ulu ʻana, ka hua, a me ka maikaʻi o nā mea kanu.
ʻEhia ka nui o ka DLI e pono ai nā mea kanu ma loko?
E nānā i ke koi DLI o nā mea kanu like ʻole i mahi nui ʻia i loko o ka hale.
| Meakanu | Koi DLI |
| Nā mea kanu malu | 6 - 10 |
| Piʻi | 9 |
| Basil | 12 |
| Broccoli | 15 - 35 |
| ʻOtomato | 20 - 30 |
| Zucchini | 25 |
| Pepa | 30 - 40 |
| Cannabis | 30 - 45 |
Hiki iā mākou ke loaʻa iā Peppers a me Cannabis kahi koi DLI kiʻekiʻe kiʻekiʻe, ʻo ia ke kumunā kukui puka PPF kiʻekiʻehe mea nui i ka mahi ʻana i kēia mau mea kanu i loko.
He aha ka pilina ma waena o PPFD a me DLI?
ʻO ke kumu no ka helu ʻana i ka DLI: μmol m-2s-1 (a i ʻole PPFD) x (3600 x photoperiod) / 1,000,000 = DLI (a i ʻole nā mole/m2/lā)
ʻO ka PPFD ka helu o nā kiʻi i hiki i kahi kikoʻī (m2) i kēlā me kēia kekona, ana ʻia i nā micromoles (μmol m-2s-1).
1.000.000 micromoles = 1 mole
3600 kekona = 1 hola
