He hua ōhanga noa te merengi, he nui te hiahia o te mākete me te kounga teitei, engari he uaua te whakatipu tipu mō te merengi me te aubergine. Ko te take matua: he hua e pai ana ki te mārama te merengi. Ki te kore e nui te māramatanga i muri i te whatinga o te tipu merengi, ka nui rawa te tipu, ka puta he tipu waewae teitei, ka pā kino ki te kounga o ngā tipu me te tipu o muri mai. Ko te merengi mai i te rui ki te whakato kei waenganui i a Hakihea o taua tau me Pēpuere o te tau e whai ake nei, koinei te wā e iti rawa ana te pāmahana, e ngoikore ana te māramatanga, ā, e tino kino ana te mate. Ina koa i te tonga o Haina, he mea noa te korenga o te rā mō ngā rā 10 ki te hawhe marama i te tīmatanga o te kōanga. Ki te mea he rangi kapua tonu, he hukarere hoki, ka mate te tini o ngā tipu, ka nui te kino ki te ōhanga o ngā kaimahi pāmu.

Ko te whakamahi i te pūtake mārama horihori, hei tauira, te mārama mai i ngā rama whakatipu LED, hei whakamahi i te "tonguru māmā" ki ngā hua tae atu ki ngā tipu merengi i raro i te āhua kāore i te rawaka te rā, kia tutuki ai te whāinga o te whakapiki i te hua, te whai huatanga teitei, te kounga teitei, te ātete ki ngā mate me te kore parahanga me te whakatairanga i te tipu me te whanaketanga o ngā hua, koinei te huarahi rangahau matua a ngā kaipūtaiao whakaputa ahuwhenua mō ngā tau maha.

I ngā tau tata nei, i kitea anō e te rangahau he pānga nui anō hoki te rerekētanga o te ōwehenga o te mārama whero me te kikorangi ki te tipu o ngā tipu. Hei tauira, i kitea e te kairangahau a Tang Dawei me ētahi atu ko te R / b = 7:3 te ōwehenga mārama whero me te kikorangi pai rawa atu mō te tipu o te tipu kūkamo; i tohu te kairangahau a Gao Yi me ētahi atu i roto i tā rātou tuhinga ko te R / b = 8:1 te pūtake mārama whakauru te whirihoranga mārama tāpiri tino pai mō te tipu o te tipu Luffa.

I mua, i ngana ētahi tāngata ki te whakamahi i ngā pūtake mārama horihori pērā i ngā rama hihiko me ngā rama konutai hei whakahaere i ngā whakamātautau tipu, engari kāore i pai te hua. Mai i te tekau tau atu i 1990, kua mahia ngā rangahau mō te whakatipu tipu mā te whakamahi i ngā rama whakatipu LED hei pūtake mārama tāpiri.

He pai ngā rama whakatipu LED mō te penapena pūngao, te tiaki taiao, te haumaru me te pono, te roa o te ora mahi, te rahi iti, te mama, te iti o te whakaputa wera me te pai o te whakahaere marara, te whakakotahi rānei i te mārama. Ka taea te whakakotahi kia rite ki ngā hiahia kia whiwhi ai i te mārama kotahi-tae me te whānuitanga hiato, ā, ka taea e te tere whakamahinga whai hua o te pūngao mārama te eke ki te 80% – 90%. E kiia ana koinei te puna mārama pai rawa atu i roto i te whakatipu.

I tēnei wā, he nui ngā rangahau kua mahia mō te whakatipu raihi, kūkamo me te pīnihi me te pūtake rama LED parakore i Haina, ā, kua kitea ētahi ahunga whakamua. Heoi, mō ngā tipu merengi he uaua ki te whakatipu, kei te noho tonu te hangarau o nāianei ki te taumata o te mārama taiao, ā, ko te rama LED anake te pūtake rama tāpiri.

I runga anō i ngā raruraru o runga ake nei, ka ngana tēnei pepa ki te whakamahi i te rama LED hei pūtake rama parakore hei ako i te whaihua o te whakatipu tipu merengi me te ōwehenga rerenga rama pai rawa atu hei whakapai ake i te kounga o ngā tipu merengi me te kore e whakawhirinaki ki te hihi o te rā, kia whakaratohia ai he pūtake ariā me te tautoko raraunga mō te whakahaere rama o ngā tipu merengi i roto i ngā whare.

A.Te tukanga whakamātautau me ngā hua

1. Ngā rauemi whakamātautau me te maimoatanga mārama

I whakamahia te merengi ZAOJIA 8424 i roto i te whakamātautau, ā, ko te reo whakatipu ko Jinhai Jinjin 3. I tīpakohia te wāhi whakamātautau i roto i te wheketere whakatipu rama LED i te Tāone o Quzhou, ā, i whakamahia ngā taputapu rama LED hei pūtake rama whakamātautau. E rima ngā huringa o te whakamātautau. Ko te wā whakamātautau kotahi he 25 ngā rā mai i te rumaki purapura, te whakatipu tae noa ki te tipu o te tipu. Ko te wā whakaahua he 8 hāora. Ko te pāmahana o roto he 25° ki te 28° i te awatea (7:00-17:00) me te 15° ki te 18° i te ahiahi (17:00-7:00). Ko te haumākū o te taiao he 60% – 80%.

E whakamahia ana ngā pīrere LED whero me te kikorangi i roto i ngā rama whakatipu LED, me te roangaru whero o te 660nm me te roangaru kikorangi o te 450nm. I roto i te whakamātautau, i whakamahia te mārama whero me te kikorangi me te ōwehenga rerenga kanapa o te 5:1, 6:1 me te 7:13 hei whakatairite.

2. Te taupū me te tikanga ine

I te mutunga o ia huringa, e toru ngā tipu i tīpakohia matapōkeretia mō te whakamātautau kounga tipu. Ko ngā taupū ko te taumaha maroke me te taumaha hou, te teitei o te tipu, te whānui o te kakau, te maha o ngā rau, te horahanga rau motuhake me te roa o te pakiaka. I roto i ēnei, ka taea te ine i te teitei o te tipu, te whānui o te kakau me te roa o te pakiaka mā te caliper vernier; ka taea te tatau ā-ringa i te maha o ngā rau me te maha o ngā pakiaka; ka taea te tatau i te taumaha maroke me te taumaha hou me te horahanga rau motuhake mā te rūri.

3. Tātaritanga tatauranga o ngā raraunga

4. Ngā Hua

Kei te Ripanga 1 me ngā pikitia 1-5 ngā hua o te whakamātautau.

Mai i te ripanga 1 me te ahua 1-5, ka kitea i te pikinga ake o te ōwehenga mārama ki te ōwehenga whiti, ka heke te taumaha maroke hou, ka piki ake te teitei o te tipu (he āhuatanga koretake te roa), ka angiangi haere te kakau o te tipu, ka iti haere te horahanga rau, ā, ka poto haere te roa o te pakiaka.

B.Te tātari me te aromatawai i ngā hua

1. Ina 5:1 te ōwehenga mārama ki te whiti, ko te tipu pai rawa atu tēnei o te merengi.

2. Ko te iti o te tipu e whiti ana i te rama whakatipu LED me te ōwehenga rama kikorangi teitei e tohu ana he pānga mārama te rama kikorangi ki te tipu o te tipu, inā koa ki te kakau o te tipu, ā, kāore he pānga mārama ki te tipu o te rau; ka whakatairanga te rama whero i te tipu o te tipu, ā, ka tere ake te tipu o te tipu ina nui te ōwehenga o te rama whero, engari he mārama tōna roa, e whakaatuhia ana i te Pikitia 2.

3. He rerekē te ōwehenga o te mārama whero me te kikorangi e hiahiatia ana e te tipu i ngā wā tipu rerekē. Hei tauira, me nui ake te mārama kikorangi e hiahiatia ana e ngā tipu merengi i te wā tōmua, ka taea te pehi i te tipu o te tipu; engari i te wā o muri mai, me nui ake te mārama whero. Ki te mau tonu te ōwehenga o te mārama kikorangi, ka iti, ka poto te tipu.

4. Kaua e tino kaha te mārama o te tipu merengi i te tīmatanga, ka pā ki te tipu o ngā tipu i muri mai. Ko te huarahi pai ko te whakamahi i te mārama ngoikore i te tīmatanga, kātahi ka whakamahi i te mārama kaha i muri mai.

5. Me whakarite kia tika te rama whakatipu LED. Kua kitea mēnā he iti rawa te kaha o te mārama, ka ngoikore te tipu o te tipu, ā, ka ngāwari te tupu noa. Me whakarite kia kaua e iti iho i te 120wml te māramatanga tipu noa o ngā tipu; heoi, kāore e kitea te huringa o te ia tipu o ngā tipu mēnā he nui rawa te māramatanga, ā, ka nui ake te whakapaunga hiko, kāore e pai mō te whakamahinga o te wheketere ā muri ake nei.

CNgā Hua

I whakaatuhia e ngā hua he mea taea te whakamahi i te pūtake mārama LED parakore hei whakatipu i ngā tipu merengi i roto i te rūma pōuri, ā, he pai ake te rere mārama 5:1 mō te tipu o ngā tipu merengi i te 6, 7 rānei ngā wā. E toru ngā kaupapa matua o te whakamahinga o te hangarau LED i roto i te whakatipu ahumahi o ngā tipu merengi.

1. He mea tino nui te ōwehenga o te mārama whero me te mārama kikorangi. Kāore e taea te whakamārama i te tipu wawe o ngā tipu merengi mā te rama tipu LED me te mārama kikorangi tino teitei, ki te kore ka pā ki te tipu o muri mai.

2. He pānga nui tō te kaha o te mārama ki te whanaketanga o ngā pūtau me ngā whekau o ngā tipu merengi. Mā te kaha o te mārama ka kaha te tipu o ngā tipu; mā te ngoikore o te mārama ka kore noa iho te tipu o ngā tipu.

3. I te wā whakatipu uri, ki te whakaritea ki ngā tipu he iti iho te kaha o te mārama i te 120 μ mol / m2 · s, ko ngā tipu he nui ake te kaha o te mārama i te 150 μ mol / m2 · s i puhoi te tipu i te wā i neke ai ki te whenua pāmu.

Ko te tipu o ngā tipu merengi te mea pai rawa atu i te wā i 5:1 te ōwehenga o te whero ki te kikorangi. E ai ki ngā pānga rerekē o te mārama kikorangi me te mārama whero ki ngā tipu, ko te huarahi pai ki te whakamārama ko te whakanui ake i te ōwehenga o te mārama kikorangi i te tīmatanga o te tipu o te tipu, me te tāpiri atu i te mārama whero i te mutunga o te tipu o te tipu; whakamahia te mārama ngoikore i te tīmatanga, kātahi ka whakamahia te mārama kaha i te mutunga.
