I-Thin film greenhouse luhlobo oluqhelekileyo lwe-greenhouse. Xa kuthelekiswa negreenhouse yeglasi, i-PC board greenhouse, njl. njl., eyona nto iphambili yokugquma ifilimu eluhlaza yifilimu yeplastiki, enexabiso eliphantsi ngokwexabiso. Ixabiso lezinto ezibonakalayo zefilimu ngokwayo liphantsi, kwaye ngokweemfuno zesakhiwo se-skeleton ye-greenhouse, i-greenhouse yefilimu ayinzima kakhulu kwaye inamandla amakhulu, ngoko ke ukukhethwa kwezinto zamathambo kunokugcina iindleko. Umzekelo, ifilimu yogcino zityalo enommandla we-1000 square metres inokuba neendleko zokwakha ezimalunga nesinye kwisithathu ukuya kwisiqingatha sendlu eluhlaza yeglasi, nto leyo eyenze ukuba ibe lukhetho olufikelelekayo kubalimi abathile abanemali enyiniweyo abafuna ukulima. zibandakanyeke kuncedo lwezolimo. Ubunzima befilimu buncinci, oku kuthetha ukuba ukuxhaswa kwenkxaso ye-greenhouse yefilimu ayifuni umthamo omkhulu wamandla ukugcina uzinzo lwesakhiwo njengamanye ama-greenhouses anezixhobo zokugubungela ezinzima. Ngaphezu koko, inkqubo yokufakela ifilimu ilula kakhulu kwaye iindleko zabasebenzi nazo ziphantsi. Ngexesha elifanayo, ngexesha lokufudumala kwebusika, ezinye iindlela ezilula zokugquma (njengokongeza iingubo zokugquma) zineendleko eziphantsi kakhulu kwii-greenhouses zefilimu, ukunciphisa iindleko zokusebenza kwe-greenhouse.

Emva kokuba isakhiwo esiphambili samathambo sakhiwe, isantya sokufakela ifilimu sikhawuleza. Xa kuthelekiswa ne-glasshouses yeglasi, i-greenhouses yefilimu ayinayo ukufakwa kweglasi eyinkimbinkimbi kunye neenkqubo zokutywinwa, ngoko ke umjikelo wokwakha jikelele umfutshane. Ubungakanani obuphakathi (500-1000 square metres) greenhouse eluhlaza, enokulungiswa okwaneleyo kwemathiriyeli kunye nabasebenzi, inokuthatha iintsuku ezimbalwa ukuya kwiveki ukugqibezela ukwakhiwa kwaye inokukhawuleza isetyenziswe kwimveliso.

Venlo style greenhousesisakhiwo esithandwayo segreenhouse, kunye neVenlo style greenhouse enefestile ephezulu evuleke ngokupheleleyo inezi nzuzo zilandelayo:
1. Ukusebenza kakuhle komoya
Isiphumo esigqwesileyo sendalo sokungenisa umoya:Ifestile ephezulu egcweleyo inokusebenzisa ngokupheleleyo uxinzelelo lobushushu kunye noxinzelelo lomoya kumoya wendalo. Xa kukho ukukhanya okwaneleyo emini, iqondo lobushushu ngaphakathi kwi-greenhouse liyenyuka, kwaye umoya oshushu uyanyuka. Ikhutshwa ngaphandle ngefestile ephezulu yokuvula, ngelixa umoya opholileyo opholileyo ovela ngaphandle ungena kwigumbi ngemingxuma yokungenisa umoya okanye izikhewu ezantsi kwe-greenhouse, zenza i-convection yendalo. Le ndlela yokungenisa umoya yendalo inokunciphisa ngokufanelekileyo ubushushu kunye nokufuma ngaphakathi kwi-greenhouse, idala indawo efanelekileyo yokukhula kwezityalo. Umzekelo, ngexesha lobushushu obuphezulu ehlotyeni, iVenlo enesitayile segreenhouse esingenisa umoya kakuhle inokulawula ubushushu bangaphakathi ukuba bube malunga ne-3-5 ℃ ngaphantsi kweqondo lobushushu langaphandle, inciphisa umonakalo wobushushu obuphezulu kwizityalo.
Ukuhambelana kakuhle komoya: Ngenxa yokusabalalisa okufanayo kweefestile eziphezulu, ukungena komoya ngaphakathi kwe-greenhouse kuninzi ngakumbi. Xa kuthelekiswa neefestile zecala, ifestile ephezulu egcweleyo inokuphepha iikona ezifileyo kwi-ventilation kwaye iqinisekise ukuba izityalo kwiindawo ezahlukeneyo zegumbi zinokunandipha umoya omtsha, onenzuzo kwi-photosynthesis yezityalo kunye nokuphefumula. Kwiindawo zokugcina izityalo ezinoxinano oluphezulu lokutyala, inzuzo ye-ventilation efanayo ibonakala ngakumbi, iqinisekisa ukuba isityalo ngasinye sinokukhula ngokusempilweni.
2, Iimeko zokukhanyisa ezaneleyo
Ubuninzi bokukhanya kwemini:IVenlo style greenhouse ibonakalisa uyilo lwefestile ephezulu evuleke ngokupheleleyo evumela igreenhouse ukuba ifumane ukukhanya kwendalo okuphezulu emini. Xa ifestile ivuliwe, ayiyi kuthintela ukukhanya kwelanga, ukuqinisekisa ukuba izityalo zangaphakathi zinokufumana ngokupheleleyo ukukhanya kwelanga. Oku kubaluleke kakhulu kwizityalo ezifuna ukukhanya okwaneleyo, njengezityalo zemifuno ezifana neetumato kunye neecucumber, kunye nezityalo ezahlukeneyo zeentyatyambo. Ukukhanya okwaneleyo kunokukhuthaza i-photosynthesis kwizityalo, ukwandisa ukuqokelela kweemveliso ze-photosynthetic, kwaye ngaloo ndlela kuphuculwe isivuno kunye nomgangatho. Xa sithetha ngokubanzi, izindlu zezityalo zeVenlo ezineefestile eziphezulu ezigcweleyo zinokukhanya okukhanyayo nge-10% -20% ngaphezulu kunezindlu zendalo ezinefestile.
Ukuhanjiswa kokukhanya okufanayo:Ifestile ephezulu inokusabalalisa ukukhanya ngokulinganayo kuzo zonke iikona ze-greenhouse. Xa kuthelekiswa ne-greenhouse ene-single-side lighting, oku kusasazwa kokukhanya okufanayo kunokunciphisa ukungafani kolwalathiso ekukhuleni kwezityalo, ukwenza ukukhula kwezityalo kufane kunye nokuhambelana. Ngokomzekelo, ekulinyweni kweentyatyambo, ukukhanya okufanayo kunceda ukufezekisa umbala ofanayo kunye nokumila rhoqo kweentyatyambo, ukuphucula ixabiso labo lokuhlobisa kunye nezorhwebo.
3. Ukonga amandla kunye nokusebenza kakuhle
Nciphisa ukusetyenziswa kwamandla okungena komoya: Ukungenisa umoya wendalo yindlela yokungenisa umoya engadingi ukusetyenziswa kwamandla okongeziweyo. Ifestile ephezulu evuleke ngokupheleleyo isebenzisa umgaqo wokungenisa umoya wendalo, ukunciphisa ukuthembela kwizixhobo zokuphefumla ngoomatshini ezifana neefeni zokukhupha umoya, ngaloo ndlela kuncitshiswa ukusetyenziswa kwamandla okungena komoya obushushu. Kubukhulu obuphakathi (malunga ne-1000 square metres) iVenlo style greenhouse, ngokusebenzisa ngokupheleleyo umoya wendalo, amawaka eeyuan kwiindleko zokusebenza zezixhobo zokungenisa umoya anokugcinwa ngonyaka.
Nciphisa iindleko zokufudumeza: Ukusebenza kakuhle kwe-ventilation kunceda ukususa ubushushu obuninzi ngexesha lobushushu kwi-greenhouse emini, ukunciphisa ubushushu obufunekayo ukufudumeza ebusuku. Ngaphezu koko, ngeentsuku ezinelanga ebusika, ukuvula ifestile ephezulu ngokufanelekileyo kunokulawula ubushushu ngaphakathi kwi-greenhouse, usebenzisa ubushushu bemitha yelanga ukugcina indawo efanelekileyo yobushushu bangaphakathi, ukunciphisa ixesha lokusetyenziswa kwezixhobo zokufudumeza, kunye nokunciphisa iindleko zokufudumeza.
4, Kulula ukulawula okusingqongileyo
Lungisa ngokukhawuleza ubushushu kunye nokufuma: Abalimi banokuhlengahlengisa ngokuguquguqukayo iqondo lokuvula kwifestile ephezulu ngokweemeko zokusingqongileyo ngaphakathi nangaphandle kwe-greenhouse kunye neemfuno zokukhula kwezityalo. Xa iqondo lokushisa kunye nomswakama uphezulu kakhulu, zonke iifestile zinokuvulwa ukunciphisa ngokukhawuleza ukushisa kunye nomswakama; Xa iqondo lokushisa liphantsi kwaye ubushushu bangaphakathi bufuna ukugcinwa, iifestile zingavalwa kwaye izixhobo zokufudumeza kunye ne-insulation zingasetyenziselwa ukugcina uzinzo lwangaphakathi. Ukukwazi ukuhlengahlengisa ngokukhawuleza okusingqongileyo kwenza ukuba iVenlo style greenhouses ihambelane neemfuno zokusingqongileyo zezityalo ezahlukeneyo kwizigaba ezahlukeneyo zokukhula.
Ukuphucula i-carbon dioxide concentration:Indawo ekusetyenzwa kuyo umoya inceda ekuzalisweni kwakhona kwekharbon diokside. Izityalo kufuneka zitye i-carbon dioxide ngexesha le-photosynthesis. I-greenhouse enefestile ephezulu evuleke ngokupheleleyo inokuvumela umoya omtsha (oqulethe umlinganiselo ofanelekileyo we-carbon dioxide) ukusuka ngaphandle ukuba ungene kwigumbi ngokungena komoya wendalo, ukuphepha ukuxinwa kwe-carbon dioxide kwi-greenhouse kunye nokuchaphazela i-photosynthesis yezityalo. Kwangaxeshanye, xa kuyimfuneko, ingxinano ye<em>carbon dioxide yangaphakathi inokulawulwa ngokuthe ngqo ngokuvala ezinye iifestile nokusebenzisa inkqubo yokuchumisa i<em>carbon dioxide ukuze kuphuculwe ukusebenza kakuhle kwephotosynthetic yezityalo.
