Ukuthuthukiswa kanye nokusetshenziswa kwe-Crossed Multi-Arch Greenhouse in Tropical China
Ukuvela kwe-Round Arc Greenhouse Structure
Ibha ye-arch yesakhiwo se-greenhouse esiyindilinga-uhlobo oluyindilinga (Umfanekiso 1a) inokusebenza okuhle komshini kanye nesakhiwo esifakeka kalula [11].Kodwa-ke, kunezinkinga ezifana nobunzima bokusebenzisa nokusebenzisa indawo engaphansi kokuphakama kwehlombe ku-greenhouse noma phakathi kwezindlu zokugcina izithombo.Ngakho, udonga oluhlangothini oluqondile uhlobo olulodwa lwe-arch greenhouse structure (Umfanekiso 1b) yathuthukiswa ngesikhathi sokukhiqiza kwangempela.Lesi sakhiwo sixazulula inkinga yokusetshenziswa kwesikhala sehlombe.Ukuze kuqhutshekwe kuthuthukiswe ukusetshenziswa komhlaba nokusebenzisa ngokugcwele izinto zokwakha, i-multi-span round-arch greenhouse structure (Umfanekiso 1c) yathuthukiswa [12,13,14,15].Lesi sakhiwo sivulekile futhi sinezinga eliphezulu lokusebenzisa umhlaba, elithuthukiswa kancane kancane libe uhlobo olukhulu lwesakhiwo samanje se-multi-span plastic greenhouse [16].
Umfanekiso 1. Ukuvela kwesakhiwo se-greenhouse esiyindilinga (iyunithi: mm).(a).Isakhiwo se-greenhouse se-Floor-arch round-arch;(b).Udonga oluhlangothini oluqondile uhlobo olulodwa lwe-arch greenhouse structure;(c).Multi-span round-arch greenhouse isakhiwo.
Ukuthuthukiswa kanye nokusetshenziswa kwe-Crossed Multi-Arch Greenhouse in Tropical China
Uma i-multi-span round arch plastic greenhouse isetshenziswa ezindaweni ezishisayo njenge-Hainan, iba nezinkinga zokungena komoya kanye nokuvikela imvula.Ngokwesibonelo, lapho izulu liba khona kungazelelwe ehlobo nasekwindla, umshini wokungenisa umoya wefilimu owugqinsi ongaphezulu kwe-greenhouse awukwazi ukuvalwa ngokushesha, futhi izitshalo ezingaphakathi kwendawo ebamba ukushisa zingalinyazwa isiphepho semvula.Abasebenzisi abaningi bayeke ukusebenzisa i-roll film ventilation mechanism futhi bamboza uphahla ngefilimu ye-roll ukuze kuqinisekiswe ukusebenza kwe-greenhouse okungangenwa yimvula, ukungenisa komoya esikhundleni sokuxazululwa ngokubeka iziteshi zokungenisa umoya phakathi kwamakhothamo;ngakho-ke, kwakhiwa imodeli yesakhiwo sokuhlukaniswa kwama-arch amaningi [17].Lesi sakhiwo saqala ukusetshenziswa e-Sanya, e-Dongfang, e-Ledong nakwezinye izindawo e-Hainan ukuze kugcinwe izithombo ze-cantaloupe, futhi ngokushesha saba uhlobo oluvamile lwe-cantaloupe greenhouse (Umfanekiso 2a) ngenxa yesakhiwo sayo esilula (asikho isidingo sokucabangela umthwalo wesishingishane; ikholomu ingafakwa ngokuqondile emhlabathini ngaphandle kokubeka isisekelo) kanye nezindleko eziphansi ngoba isetshenziswa kuphela ebusika nasentwasahlobo (asikho isishingishane kanye neziphepho ezimbalwa).Ngokukhuthazwa yilokhu, abaklami bezakhiwo benze ukuthuthukiswa okuthile (Umfanekiso 2b) esakhiweni esihlukanisa ama-arch amaningi futhi wasisebenzisela ukutshala imifino ehlobo nasekwindla e-Hainan.Ngemuva kweminyaka yokusebenza, isakhiwo sithole imiphumela emihle.Njengoba isetshenziselwa ikakhulukazi ukukhiqizwa kwesizini ehlobo nasekwindla, kuyadingeka ukucabangela ukumelana nezivunguvungu.Isisekelo esizimele sidinga ukusethwa kukholamu, kusetshenziswe izinto ezinkulu nezinamandla, futhi izindleko kufanele okungenani zibe kabili kunezokugcina izithombo ze-cantaloupe.
Umfanekiso 2. I-multi-span round arch plastic greenhouse ene-in-greenhouse ventilation channel (iyunithi: mm).(a) Ukwakheka kwendlu yokushisa ye-cantaloupe;(b) Ukwakheka kwendawo yokushisa izitshalo yaseHainan unyaka wonke.
