|Abstract|

Ma ka hoʻohana ʻana i ka ryegrass ma ke ʻano he mea hoʻāʻo, ua hoʻohana ʻia ke ʻano moʻomeheu 32-tray plug tray matrix moʻomeheu e aʻo i nā hopena o nā kumukūʻai kanu (7, 14 mau ʻai/pā) ma nā ʻohi ʻekolu o ka ryegrass i mahi ʻia me ke kukui keʻokeʻo LED (ka 17th, 34th. , 51 lā) hopena i ka hua.Hōʻike nā hopena e hiki ke ulu maʻamau ka ryegrass ma lalo o ke kukui keʻokeʻo LED, a wikiwiki ka wikiwiki o ka hoʻoponopono 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 nui o ke kanu ʻana i ka hua.I loko o nā ʻokiʻoki ʻekolu, ʻoi aku ka kiʻekiʻe o ka hua o 14 mau kīʻaha/pā ma mua o 7 mau kīʻaha/pā.Ua hōʻike ʻia nā hua o nā hua kanu ʻelua i ke ʻano o ka emi mua ʻana a laila hoʻonui.He 11.11 a me 15.51 kg/㎡ ka nui o na hua o 7 mau hua/pa a me 14, a ua hiki ia lakou ke noi kalepa.

Nā mea a me nā ʻano hana

Nā mea ho'āʻo a me nā ʻano hana

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

Hoao Hoao

Hoʻonohonoho ʻia ka māmā māmā o ka LED keʻokeʻo i 350 μmol/(㎡/s), ʻo ka māhele spectral e like me ka mea i hōʻike ʻia ma ke kiʻi, ʻo ka manawa pōʻeleʻele he 16 h/8 h, a ʻo ka manawa māmā he 5:00~ 21:00.Ua hoʻonohonoho ʻia ʻelua mau hua kanu no ka lūlū ʻana.Ma kēia hoʻokolohua, kanu ʻia nā hua ma Nowemapa 2, 2021. Ma hope o ka lūlū ʻana, kanu ʻia lākou i ka pōʻeleʻele.Hoʻomaka ka hoʻomālamalama ʻana i ka lā 5 o Nowemapa. I ka wā mahi māmā, ua hoʻohui ʻia ka hoʻonā meaʻai ʻo Hoagland i ka pā seedling.

Spectrum no ke kukui keʻokeʻo LED

Nā hōʻailona hōʻiliʻili a me nā ʻano hana

E nānā ana i ka hiki ʻana o ke kiʻekiʻe kiʻekiʻe 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 Kekemapa 26, kēlā me kēia, me ka manawa o 17 mau lā.ʻO ke kiʻekiʻe o ka ʻōpala he 2.5 ± 0.5 knm, a ua koho ʻia nā mea kanu i loko o 3 mau lua i ka wā o ka ʻohi ʻana, a ua kaupaona ʻia ka ryegrass i ʻohi ʻia a hoʻopaʻa ʻia, a ua helu ʻia ka hua no kēlā me kēia mika square ma ke ʻano (1).ʻO ka hua, ʻo W ke kaumaha hou o kēlā me kēia ʻōpala ʻoki.

Ka 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 density kanu ʻelua ʻo ia ka hua mua > ke kolu o ka hua > ka lua o ka hua, 24.7 g > 15.41 g > 12.35 g (7 grains/hole), 36.6 g > 19.72 g, kēlā me kēia.＞16.98 g (14 capsules/puka).He ʻokoʻa koʻikoʻi ma waena o nā mānoanoa kanu ʻelua i ka hua o ka hua mua, akā ʻaʻohe ʻokoʻa nui ma waena o ka lua, ke kolu o ka hua a me ka hua nui.

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

E like me nā hoʻolālā ʻoki like ʻole, helu ʻia ka pōʻai hana.Hoʻokahi pōʻaiapuni ʻoki ʻana he 20 lā;ʻelua mau ʻokiʻoki he 37 lā;a ʻekolu ʻoki ʻia he 54 lā.He haʻahaʻa loa ka hua o ka hua kanu ʻana o 7 mau ʻai/pu, he 5.23 kg/㎡ wale nō.Inā he 14 mau ʻoki/pu ka nui o ka hua, ʻo ka hua kumulative o 3 ʻokiʻoki he 15.51 kg/㎡, ʻo ia ma kahi o 3 mau manawa o ka hua ʻana o 7 mau ʻoki/pu i ka manawa hoʻokahi, a ʻoi aku ka kiʻekiʻe ma mua o nā manawa ʻoki ʻē aʻe.ʻO ka lōʻihi o ka ulu ʻana o nā ʻoki ʻekolu he 2.7 manawa o ka ʻoki hoʻokahi, akā ʻo ka loaʻa ʻana he 2 wale nō ka manawa o ka ʻoki hoʻokahi.ʻAʻohe ʻokoʻa koʻikoʻi o ka hua i ka wā e ʻoki ʻia ai ka hua kanu i 7 mau ʻano ʻoki ʻoki ʻia i 3 mau manawa a me 14 mau ʻai/ʻoki ʻoki ʻana i 2 mau manawa, akā ʻo ka ʻokoʻa o ke kaʻina hana ma waena o nā ʻano ʻelua he 17 mau lā.I ka wā i ʻoki ʻia ai ka hua kanu he 14 ʻai/puka hoʻokahi, ʻaʻole i ʻokoʻa loa ka hua mai ka ʻoki ʻana o 7 mau ʻai/pu i hoʻokahi a ʻelua paha.

ʻO ka hua o ka ryegrass mowed 1-3 mau manawa ma lalo o ʻelua mau hua kanu

I ka hana ʻana, pono e hoʻolālā ʻia kahi helu kūpono o nā papa, ke kiʻekiʻe o ka papa, a me ka helu hua e hoʻonui i ka hua i kēlā me kēia ʻāpana, a pono e hui pū ʻia ka ʻoki ʻana i ka manawa me ka loiloi maikaʻi ʻai 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, ʻike pū ʻia ka ʻoihana pāʻai me nā pilikia o kahi ʻōnaehana kaila huahana kūpono ʻole a me ka pae kūʻai haʻahaʻa haʻahaʻa.Hiki ke hoʻolaha wale ʻia i nā wahi kūloko, ʻaʻole kūpono i ka ʻike ʻana i ka hui ʻana o ka mauʻu a me nā holoholona ma ka ʻāina.ʻAʻole hiki i ka mea kanu hale hana ke hoʻopōkole wale i ka pōʻai ʻai o ka ryegrass, hoʻomaikaʻi i ka helu hoʻopuka no kēlā me kēia ʻāpana, a loaʻa i ka lako makahiki o ka mauʻu hou, akā hiki nō ke kūkulu i nā hale hana e like me ka māhele ʻāina a me ka ʻoihana ʻoihana o ka mahiʻai holoholona, ​​​​e hōʻemi ana i nā kumukūʻai logistic.

Hōʻuluʻulu manaʻo

I ka hōʻuluʻulu ʻana, hiki ke hana i ka ryegrass ma lalo o ke kukui kukui LED.Ua ʻoi aku ka kiʻekiʻe o nā hua o 7 mau kīʻaha/pu a me 14 mau kīʻaha/pu ma mua o ka hua mua, e hōʻike ana i ke ʻano like o ka emi mua ʻana a ma hope o ka hoʻonui ʻana.ʻO nā hua o nā hua kanu ʻelua i hiki i 11.11 kg/㎡ a me 15.51 kg/㎡ i 54 mau lā.No laila, hiki i ka hana ʻana i ka ryegrass i nā hale mea kanu ke hiki ke noi ʻoihana.
