Uphuhliso kunye nokuSetyenziswa kweCrossed Multi-Arch Greenhouse kwiTropiki yaseTshayina
I-Evolution ye-Round Arc Greenhouse Structure
Ibha ye-arch yomgangatho-uhlobo olujikelezayo lwesakhiwo sendlu eluhlaza (Umfanekiso woku-1a) inokusebenza kakuhle koomatshini kunye nesakhiwo ekulula ukusifaka [11].Nangona kunjalo, kukho iingxaki ezinjengobunzima bokusebenzisa kunye nokusebenza kwendawo engaphantsi kobude begxalaba kwi-greenhouse okanye phakathi kwee-greenhouses.Ngaloo ndlela, udonga oluthe tye uhlobo olulodwa lwesakhiwo se-arch greenhouse (Umfanekiso woku-1b) yaphuhliswa ngexesha lemveliso yokwenyani.Esi sakhiwo sisombulula ingxaki yokusetyenziswa kwendawo yamagxa.Ukuphucula ngakumbi ukusetyenziswa komhlaba kunye nokusetyenziswa ngokupheleleyo kwezixhobo zesakhiwo, i-multi-span round-arch greenhouse structure (Umfanekiso woku-1c) yaphuhliswa [12,13,14,15].Esi sakhiwo sibanzi kwaye sinezinga eliphezulu lokusetyenziswa komhlaba, eliphuhliswa ngokuthe ngcembe libe yindlela enkulu yolwakhiwo lwangoku lweplasitiki yegreenhouse yangoku.16].

Uphuhliso kunye nokuSetyenziswa kweCrossed Multi-Arch Greenhouse kwiTropiki yaseTshayina
Xa i-multi-span round arch greenhouse yeplastiki isetyenziswa kwiindawo ezishushu ezifana ne-Hainan, ineengxaki zokuphefumla kunye nokukhusela imvula.Ngokomzekelo, xa kugaleleka imvula ngequbuliso ehlotyeni nasekwindla, inkqubo yokufaka umoya yokuphefumla ifilim engaphezulu kwendlu eluhlaza ayinakuvalwa ngokukhawuleza, yaye izityalo ezingaphakathi kwindlu eluhlaza zinokonakaliswa sisiphango semvula.Abasebenzisi abaninzi bayeke ukusebenzisa i-roll film ventilation mechanism kwaye bagquma uphahla ngefilimu eqengqelekayo ukuze kuqinisekiswe ukusebenza kwemvula kwi-greenhouse, indawo yokungena umoya isonjululwe ngokubeka imijelo yokungenisa umoya phakathi kwee-arches;ngoko, umfuziselo wolwahlulo olwahlulahlulo oluninzi lwenziwa [17].Esi sakhiwo saqala ukusetyenziswa eSanya, eDongfang, eLedong, nakwezinye iindawo eHainan kwizindlu zokugcina izityalo zecantaloupe, kwaye ngokukhawuleza yaba luhlobo oluqhelekileyo lwe-cantaloupe greenhouse (Umfanekiso wesi-2a) ngenxa yesakhiwo sayo esilula (akukho mfuneko yokuqwalasela umthwalo we-typhoon; ikholomu inokufakwa ngokuthe ngqo emhlabeni ngaphandle kokubeka isiseko) kunye neendleko eziphantsi kuba isetyenziswe kuphela ebusika nasentwasahlobo (akukho siqhwithi kunye neemvula ezincinci).Ngokukhuthazwa koku, abayili bezakhiwo benze uphuculo oluthile (Umfanekiso wesi-2b) kulwakhiwo olunearch ezininzi kwaye lusetyenziselwe ukulima imifuno yasehlotyeni nasekwindla eHainan.Emva kweminyaka yokusebenza, isakhiwo sifumene iziphumo ezilungileyo.Njengoko isetyenziswa kakhulu kwimveliso ye-off-season ehlotyeni nasekwindla, kuyimfuneko ukuqwalasela ukuxhathisa ngokuchasene neenkanyamba.Isiseko esizimeleyo kufuneka simiselwe kwikholomu, kufuneka kusetyenziswe izinto ezinkulu kunye nezinamandla, kwaye iindleko kufuneka zibe ubuncinane kabini kwi-cantaloupe greenhouses.
Umzobo 2. Multi-span round arch yeplastiki greenhouse kunye ne-in-greenhouse umjelo wokungenisa umoya (iyunithi: mm).(a) Ubume bendlu eluhlaza yecantaloupe;(b) Ubume beHainan unyaka wonke wemveliso yemifuno.
