ʻO ka hopena o ka mālamalama i ka ulu ʻana o ka mea kanu, ʻo ia ka paipai ʻana i ka chlorophyll mea kanu e hoʻomoʻa i nā meaʻai e like me ka carbon dioxide a me ka wai e synthesize i nā carbohydrates.Hiki i ka ʻepekema hou ke ʻae i nā mea kanu e ulu maikaʻi ma nā wahi ʻaʻohe lā, a me ka hana ʻana i nā kumu kukui e hiki ai i nā mea kanu ke hoʻopau i ke kaʻina hana kiʻi kiʻi.Hoʻokomo ʻia ka ʻenehana māmā hou a i ʻole ka ʻenehana kukui artificial piha.Ua ʻike ka poʻe ʻepekema ʻo ka ʻāpana uliuli a me ka ʻulaʻula e pili kokoke ana i ka pihi kūpono o ka photosynthesis o nā mea kanu, a ʻo lākou ke kumu kukui e pono ai no ka ulu ʻana o nā mea kanu.Ua aʻo ka poʻe i ke kumu o loko e pono ai nā mea kanu no ka lā, ʻo ia ka photosynthesis o nā lau.Pono ka photosynthesis o nā lau i ka hauʻoli o nā kiʻi kiʻi waho e hoʻopau i ke kaʻina hana photosynthetic holoʻokoʻa.ʻO nā kukuna o ka lā ke kaʻina hoʻolako ikehu e hoʻoulu ʻia e nā photons.
Ua kapa ʻia ke kumu kukui LED he kumu kukui semiconductor.He haiki haiki keia kumu malamalama a hiki ke hoomalu i ke kala o ke kukui.ʻO ka hoʻohana ʻana iā ia e hoʻomālamalama i nā mea kanu wale nō hiki ke hoʻomaikaʻi i nā ʻano mea kanu.
ʻIke kumu o ke kukui mea kanu LED:
1. He mau hopena like 'ole ko ka nalu nalu o ka malamalama i ka photosynthesis o ka mea kanu.ʻO ka mālamalama e pono ai no ka photosynthesis o nā mea kanu he 400-700nm ka lōʻihi.ʻO 400-500nm (uliuli) māmā a me 610-720nm (ʻulaʻula) hāʻawi nui i ka photosynthesis.
2. Hiki i nā LED polū (470nm) a me ka ʻulaʻula (630nm) ke hāʻawi wale i ke kukui e pono ai nā mea kanu.No laila, ʻo ke koho kūpono no nā kukui mea kanu LED ʻo ia ka hoʻohana ʻana i ka hui pū ʻana o kēia mau kala ʻelua.Ma ke ʻano o nā hopena ʻike, ʻike ʻia nā kukui mea kanu ʻulaʻula a me ka polū.
3. Hiki i ke kukui polū ke hoʻoikaika i ka ulu ʻana o nā lau ʻōmaʻomaʻo;kōkua ke kukui ʻulaʻula no ka pua ʻana a me ka hua ʻana a hoʻolōʻihi i ka wā pua.
4. ʻO ka lakio o nā LED ʻulaʻula a me ka uliuli o nā kukui mea kanu LED ma waena o 4: 1--9: 1, a maʻamau 4-7: 1.
5. Ke hoʻohana ʻia nā kukui mea kanu e hoʻopiha i nā mea kanu me ka mālamalama, ʻo ke kiʻekiʻe mai nā lau ma kahi o 0.5 mau mika, a me ka hoʻomau mau ʻana no nā hola 12-16 i ka lā hiki ke hoʻololi loa i ka lā.
E hoʻohana i nā ʻōpuʻu semiconductor LED e hoʻonohonoho i ke kumu kukui kūpono loa no ka ulu ʻana o nā mea kanu
Hiki i nā kukui kala i hoʻonohonoho ʻia i ka ʻāpana hiki ke hana i nā strawberries a me nā tōmato i ʻono a ʻoi aku ka momona.ʻO ka hoʻomālamalama ʻana i nā mea kanu holly me ka mālamalama e hoʻohālike i ka photosynthesis o nā mea kanu ma waho.ʻO ka Photosynthesis ka hana e hoʻohana ai nā mea kanu ʻōmaʻomaʻo i ka ikehu māmā ma o nā chloroplasts e hoʻololi i ka carbon dioxide a me ka wai i loko o ka ikehu mālama mea ola a hoʻokuʻu i ka oxygen.Hoʻokumu ʻia ka mālamalama o ka lā i nā kala like ʻole o ka mālamalama, a hiki i nā kala like ʻole o ka mālamalama ke loaʻa nā hopena like ʻole i ka ulu ʻana o nā mea kanu.
Ua kiʻekiʻe nā hua holly i hoʻāʻo ʻia ma lalo o ke kukui poni, akā liʻiliʻi nā lau, pāpaʻu ke aʻa, a ʻano ʻai ʻole.ʻAʻole pōkole wale nā mea kanu ma lalo o ke kukui melemele, akā ke nānā aku nā lau i ke ola ʻole.ʻO ka holly e ulu ana ma lalo o ke kukui ʻulaʻula i hui pū ʻia e ulu maikaʻi, ʻaʻole ikaika wale nō, akā ua hoʻomohala nui ʻia ka ʻōnaehana kumu.ʻO ka ʻulaʻula a me ka ʻulaʻula uliuli o kēia kumu kukui LED i hoʻonohonoho ʻia i ka ratio o 9:1.
Hōʻike nā hopena i ka 9: 1 ʻulaʻula a me ka uliuli kukui ka mea maikaʻi loa i ka ulu ulu.Ma hope o ka hoʻomālamalama ʻia ʻana o kēia kumu kukui, ʻoi aku ka nui o nā hua strawberry a me nā ʻōmato, a ua hoʻonui nui ʻia ka ʻike o ke kō a me ka huaora C, ʻaʻohe mea hollow.ʻO ka hoʻomaʻamaʻa mau ʻana no 12-16 mau hola i ka lā, ʻoi aku ka ʻono o nā hua ʻōmaʻomaʻo maʻamau i ulu ʻia ma lalo o kahi kumu kukui.
