Kuvandudza uye Kushandiswa kweCrossed Multi-Arch Greenhouse muTropical China
Evolution yeRound Arc Greenhouse Structure
Iyo arch bar yepasi-rudzi rwekutenderera-arch greenhouse chimiro (Mufananidzo 1a) ine yakanaka mashandiro emuchina uye nyore-kuisa-kumisikidza [11].Nekudaro, kunewo matambudziko akadai sekuomerwa kwekushandisa uye kushanda nzvimbo iri pasi pemapfudzi urefu mugreenhouse kana pakati pegreenhouses.Saka, yakatwasuka padivi madziro mhando imwe arch greenhouse chimiro (Mufananidzo 1b) yakagadzirwa panguva yekugadzirwa chaiko.Ichi chimiro chinogadzirisa dambudziko rekushandisa nzvimbo yemafudzi.Kuti uwedzere kuvandudza kushandiswa kwepasi uye kushandisa zvizere zvezvimiro zvekugadzira, yakawanda-span yakatenderera-arch greenhouse chimiro (Mufananidzo 1c) yakagadzirwa [12,13,14,15].Chimiro ichi chakapamhama uye chine huwandu hwekushandiswa kwevhu, iyo iri kuvandudzwa zvishoma nezvishoma kuita chimiro chikuru cheiyo yazvino multi-span plastiki greenhouse [16].

Kuvandudza uye Kushandiswa kweCrossed Multi-Arch Greenhouse muTropical China
Kana iyo yakawanda-span yakatenderedza arch yepurasitiki greenhouse ichishandiswa munzvimbo dzinopisa seHainan, ine mhepo uye matambudziko ekudzivirira mvura.Semuenzaniso, kana dutu remvura rakangoerekana raitika muzhizha uye matsutso, iyo roll film ventilation mechanism iri pamusoro pegreenhouse haigone kuvharwa nekukurumidza, uye zvirimwa zviri mukati megreenhouse zvinogona kukuvadzwa nedutu remvura.Vazhinji vashandisi vakamira kushandisa roll film ventilation mechanism uye vakavhara denga nemupumburu firimu kuti ive nechokwadi chekuti kusanaya kwemvura kwegreenhouse, kufefetera pachinzvimbo kuchigadziriswa nekuisa migero yemhepo pakati pematanho;saka, iyo yakawanda-arch kupatsanurwa chimiro modhi yakaumbwa [17].Ichi chivakwa chakatanga kushandiswa muSanya, Dongfang, Ledong, nedzimwe nzvimbo muHainan kune cantaloupe greenhouses, uye yakakurumidza kuve iyo mainstream cantaloupe greenhouse type (Mufananidzo 2a) nekuda kwechimiro chayo chakareruka (hapana chikonzero chekufunga nezvedutu remutoro; iyo mbiru inogona kuiswa zvakananga muvhu pasina kuisa hwaro) uye yakaderera mutengo nekuti inongoshandiswa munguva yechando uye muchirimo (hapana dutu uye mashoma emvura).Vafemerwa neizvi, vagadziri vezvimiro vakaita zvimwe kuvandudzwa (Mufananidzo 2b) kune yakawanda-arch split dhizaini uye akaishandisa kurima kwechirimo nematsutso muriwo muHainan.Mushure memakore ekudzidzira, chimiro chakawana zvibereko zvakanaka.Sezvo inonyanya kushandiswa kugadzirwa kwe-off-mwaka muzhizha uye matsutso, zvinodikanwa kufunga nezvekupikisa kurwisa madutu.Hwaro hwakazvimirira hunoda kugadzikwa pambiru, zvinhu zvakakura uye zvakasimba zvinofanirwa kushandiswa, uye mutengo unofanirwa kuve wakapetwa kaviri weiyo cantaloupe greenhouses.
