Ma ka hoʻohana ʻana i ka ryegrass ma ke ʻano he mea hoʻāʻo, ua hoʻohana ʻia ke ʻano hana moʻomeheu tray plug 32-tray e aʻo ai i nā hopena o nā helu kanu (7, 14 mau hua/pā) ma nā ʻohi ʻekolu o ka ryegrass i mahi ʻia me ke kukui keʻokeʻo LED (ka lā 17, 34, 51 lā) ka hopena ma ka hua. Hōʻike nā hopena hiki i ka ryegrass ke ulu maʻamau ma lalo o ke kukui keʻokeʻo LED, a wikiwiki ka wikiwiki o ka hana hou ʻana ma hope o ka ʻoki ʻana, a hiki ke hana ʻia e like me nā ʻano ʻohi he nui. He hopena koʻikoʻi ka helu lūlū ma ka hua. I loko o nā ʻoki ʻekolu, ʻoi aku ka kiʻekiʻe o ka hua o 14 mau hua/pā ma mua o 7 mau hua/pā. Ua hōʻike nā hua o nā helu lūlū ʻelua i kahi ʻano o ka emi mua ʻana a laila hoʻonui. ʻO ka huina o nā hua o 7 mau hua/pā a me 14 mau hua/pā he 11.11 a me 15.51 kg/㎡, kēlā me kēia, a loaʻa iā lākou ka hiki ke hoʻohana ʻia ma ke kālepa.

Nā Mea Hana a me nā ʻAno Hana

Nā Mea Hoʻāʻo a me nā ʻAno Hana

ʻO ka mahana i loko o ka hale hana he 24±2 °C, ʻo ka haʻahaʻa pili he 35%–50%, a ʻo ka nui o ka CO2 he 500±50 μmol/mol. Ua hoʻohana ʻia kahi kukui panel LED keʻokeʻo me ka nui o 49 cm × 49 cm no ka hoʻomālamalama ʻana, a ua kau ʻia ke kukui panel he 40 cm ma luna o ka pā plug. ʻO ka lakio o ka matrix he peat: perlite: vermiculite = 3:1:1, e hoʻohui i ka wai i hoʻoheheʻe ʻia e hui like, e hoʻoponopono i ka nui o ka wai i 55% ~ 60%, a mālama iā ia no 2 ~ 3 mau hola ma hope o ka omo piha ʻana o ka matrix i ka wai a laila e hoʻokomo like iā ia i loko o 54 cm × 28 cm i loko o kahi plug 32-puka. E koho i nā hua momona a like ka nui no ka lūlū ʻana.

Hoʻolālā Hoʻāʻo

Ua hoʻonohonoho ʻia ka ikaika o ke kukui o ka LED keʻokeʻo i 350 μmol/(㎡/s), ʻo ka hoʻolaha spectral e like me ka mea i hōʻike ʻia ma ke kiʻi, ʻo ka wā mālamalama-poʻeleʻele he 16 h/8 h, a ʻo ka wā mālamalama he 5:00~21:00. Ua hoʻonohonoho ʻia ʻelua mau mānoanoa lūlū o 7 a me 14 mau ʻano/lua no ka lūlū ʻana. Ma kēia hoʻokolohua, ua lūlū ʻia nā hua ma Nowemapa 2, 2021. Ma hope o ka lūlū ʻana, ua mahi ʻia lākou i ka pouli. Ua hoʻomaka ʻia ke kukui ʻana ma Nowemapa 5. I ka wā mahi kukui, ua hoʻohui ʻia ka hopena meaʻai Hoagland i ka pā kanu hua.

ʻAno uila no ke kukui keʻokeʻo LED

Nā Hōʻailona a me nā ʻAno Hana o ka ʻOhi ʻAi

Ke nānā nei i ka wā e hiki ai ke kiʻekiʻe awelika o nā mea kanu i ke kiʻekiʻe o ke kukui panel, e ʻohi iā ia. Ua ʻoki ʻia lākou ma Nowemapa 22, Dekemaba 9 a me Dekemaba 26, kēlā me kēia, me kahi manawa o 17 mau lā. ʻO ke kiʻekiʻe o ka ʻōpala he 2.5 ± 0.5 cm, a ua koho wale ʻia nā mea kanu i loko o 3 mau lua i ka wā o ka ʻohi ʻana, a ua kaupaona ʻia a hoʻopaʻa ʻia ka ryegrass i ʻohi ʻia, a ua helu ʻia ka hua no ka mika kūlike ma ke ʻano (1). ʻO ka hua, W ke kaumaha hou o kēlā me kēia ʻōpala ʻoki.

Hua = (W × 32) / 0.1512 / 1000 (kg / ㎡)

(ʻĀpana pā = 0.54 × 0.28 = 0.1512 ㎡) (1)

Nā Hualoaʻa a me ka Nānā ʻana

Ma ke ʻano o ka hua awelika, ʻo nā ʻano hua o nā ʻano kanu ʻelua, ʻo ia ka mea kanu mua > ka mea kanu ʻekolu > ka mea kanu ʻelua, 24.7 g > 15.41 g > 12.35 g (7 mau ʻano/lua), 36.6 g > 19.72 g, kēlā me kēia. ＞16.98 g (14 mau capsules/lua). He ʻokoʻa koʻikoʻi ma waena o nā ʻano kanu ʻelua i ka hua o ka mea kanu mua, akā ʻaʻohe ʻokoʻa koʻikoʻi ma waena o ka mea kanu ʻelua, ka mea kanu ʻekolu a me ka hua holoʻokoʻa.

Nā hopena o ka nui o ka lūlū ʻana a me nā manawa ʻoki ʻōpala i ka hua ryegrass

Wahi a nā hoʻolālā ʻoki like ʻole, ua helu ʻia ke kaʻina hana. ʻO hoʻokahi kaʻina hana ʻoki he 20 mau lā; ʻelua mau ʻoki he 37 mau lā; a ʻekolu mau ʻoki he 54 mau lā. ʻO ka nui o ka lūlū ʻana o 7 mau hua/lua ka mea i loaʻa ka hua haʻahaʻa loa, ʻo 5.23 kg/㎡ wale nō. I ka wā i 14 mau hua/lua ka nui o ka lūlū ʻana, ʻo ka nui o ka lūlū ʻana o 3 mau ʻoki he 15.51 kg/㎡, ʻo ia hoʻi ma kahi o 3 manawa o ka hua o 7 mau hua/lua ʻokiʻoki 1 manawa, a ʻoi aku ka kiʻekiʻe ma mua o nā manawa ʻoki ʻē aʻe. ʻO ka lōʻihi o ke kaʻina ulu ʻana o ʻekolu mau ʻoki he 2.7 manawa o ka ʻoki hoʻokahi, akā ʻo ka hua he 2 wale nō manawa o ka ʻoki hoʻokahi. ʻAʻohe ʻokoʻa koʻikoʻi o ka hua i ka wā i 7 mau hua/lua ʻoki ʻia 3 manawa ka nui o ka lūlū ʻana a me 14 mau hua/lua ʻoki ʻia 2 manawa, akā ʻo ka ʻokoʻa o ke kaʻina hana ma waena o nā ʻano hana ʻelua he 17 mau lā. I ka wā i 14 mau hua/lua ʻoki ʻia hoʻokahi manawa ka nui o ka lūlū ʻana, ʻaʻole ʻokoʻa nui ka hua mai ka 7 mau hua/lua ʻoki ʻia hoʻokahi a ʻelua paha.

ʻO ka hua o ka ryegrass i ʻoki ʻia i 1-3 mau manawa ma lalo o ʻelua mau helu lūlū

I ka hana ʻana, pono e hoʻolālā ʻia kahi helu kūpono o nā papa, ke kiʻekiʻe o ka papa, a me ka nui o ka lūlū ʻana e hoʻonui i ka hua ma kēlā me kēia wahi, a pono e hui pū ʻia ka ʻoki ʻana i ka manawa kūpono me ka loiloi maikaʻi o ka meaʻai e hoʻomaikaʻi i ka maikaʻi o ka huahana. Pono e noʻonoʻo ʻia nā kumukūʻai waiwai e like me nā hua, ka hana, a me ka mālama ʻana i ka mauʻu hou. I kēia manawa, ke kū nei ka ʻoihana mahiʻai i nā pilikia o kahi ʻōnaehana hoʻolaha huahana kūpono ʻole a me ka pae kūʻai haʻahaʻa. Hiki ke hoʻolaha wale ʻia ma nā wahi kūloko, ʻaʻole ia he mea kūpono i ka hoʻokō ʻana i ka hui pū ʻana o ka mauʻu a me nā holoholona ma ka ʻāina. ʻAʻole hiki i ka hana ʻana o nā hale hana mea kanu ke hoʻopōkole wale i ke kaʻina hana ʻohi o ka ryegrass, hoʻomaikaʻi i ka nui o ka hana ma kēlā me kēia wahi, a hoʻokō i ka lako mauʻu hou i kēlā me kēia makahiki, akā hiki nō hoʻi ke kūkulu i nā hale hana e like me ka hoʻolaha ʻāina a me ka nui o ka ʻoihana o ka mahiʻai holoholona, ​​e hōʻemi ana i nā kumukūʻai logistics.

Hōʻuluʻulu manaʻo

I ka hōʻuluʻulu ʻana, hiki ke hana i ka ryegrass ma lalo o ke kukui LED. ʻOi aku ka kiʻekiʻe o ka hua o 7 mau hua/lua a me 14 mau hua/lua ma mua o ka hua mua, e hōʻike ana i ke ʻano like o ka emi mua ʻana a laila ka hoʻonui ʻana. Ua hōʻea ka hua o nā helu lūlū ʻelua i 11.11 kg/㎡ a me 15.51 kg/㎡ i 54 mau lā. No laila, hiki ke hoʻohana ʻia ka ryegrass ma nā hale hana mea kanu no ke kālepa.
