isisu sokuqinisekisa somphakathi wokubuya

Izinkinga zomthwalo wophetha lwe-greenhouse uzokubiza isiphumo esincane kakhulu ngemibuzo yobunyebo bama-agricultural professionals kunye nabo-bhobiist gardener. Izicwangciso ezikhoyo zihlala phakathi kwe-$0.50 kunye ne-$2.50 ngaphandle kwesikhandla sesikhele sifuthe, umphandlanyo wophetha, kunye nokuprotekela kwe-UV. Ii-filamu leshumi lekhulu le-greenhouse lihlobene ngezindlela ezimbili zokugqunywa, ukuhlanganiswa nokuthi kune-UV stabilizers kunye ne-infrared retention properties okungabizwa ukuba akufinyeleleyo iingxenyeko zayo kwi-4-5 years. Umthengiso wamalayini akuyona amagcindezi amaningi ngokusho ukuthi umphandlanyo (umkhuhlane we-4-8 mil), imigomo yesithoba sesithathu (85-95%), kunye nokuthi kungenani nokuhlola kwehlukene. Ngokulandelana noma amacocha, ii-plastic eziyi-greenhouse ezinamandla emasakweni yakwesentloko zihlala nge-anti-condensation treatments kunye ne-diffused light properties, okungakubonisa izinkqubo ezidingekileyo zokuhlola. Imali yendawo iyahamba ngezikhetho zokusuka kwe-polyethylene ezintle zokusuka ku-advanced ethylene-vinyl acetate (EVA) amathetheli, amaphi amalayini angavariyinga ngokubanzi. Abantu ababudzeti babenza ngokukhetha iiphepu le-4-mil polyethylene, xa ke amaphrojekthi engasekisekisi ayahlula kunye nokuthi kungenani nokuhlola kwehlukene. Ukuthi amalayini angavashayiswayo kungaba ngokwesiphumo sokuthi singezansi ngokwesiko lesikhaya, amathetheli amacingo, kunye nokuthi kungenani nokusebenza kakhulu.

Ukuphikiswa kwezindlela ezikhathalelweyo kweplastiki lekhopha lasegreenhouse ligcinikeleyo amanqaku angaphezu lokunyelela ababekelise. Yilo, umdinga omphakathi wokuthi lamaqhawu akhona ubungako obuhle phakathi komhlaba, ngisho ngenxa yokuqaphela kwesintuthuko esingazibhalwa ngokubalulekileyo kakhulu kunye nokuziphindaphinda ukusetyenziswa kwesintuthuko. Ukuphatha okulandelayo kumangene amaqhawu angaphumeleyo ngokukhetha izinkinga zabo ezidingayo nezinyezi zabo. Amakhwalelo amahluhlu amaningi akufanele ukuprotekela ngokukhulu lokusebenza ngemuva kokudala, kunye nemakhwalelo engamandla apha ahlukene ngezinga lokusebenza olungaphansi olungayiphothula ukuthi kulandelayo kwezinhlangano zokusebenza. Isilinganiso somncedisi wesintu wakhiwo ukuba ababekelise bayenza iimboniso ezinomsindo ngokubhekisisa okungavakashiwe ngokuncane. Ngakho ke, umdlalo omncedisi weplastiki wakhiwo wahlukene ukuthi imali yokugcina kuyahlukene, futhi awunene ukuthola ukuze kube khona ukubuyekeza indlela eyona. Umbiko wokuhlukanisa wemvume weplastiki lemoderni wakhiwo wahlukene ngokuthi wahlukene ukuthi wakhiwe ngokuphakamisana ngesintu sokugcina umoya, ukususa imali yesihlanu sekhefu kunye nokusetshenziswa kwezinga lokusebenza. Ukuphawula kwezindlela ezifanekiso eziningi ezitholakala kwiimarkethi ezikhathalelweyo ibonisele izindlela ezincinci ezitholakala eziphakamisana nokuthi zizoshintsha ngokubalulekileyo, futhi zithole amanani amaningi amanye amadala. Lomusho olungaphambili lwakhiwe ukuthi amandla amaningi amashonaleni akhona ngokubalulekileyo, apho amandla amaningi amashonaleni akhona ngokubalulekileyo, apho amandla amaningi amashonaleni akhona ngokubalulekileyo.

Ukuphatha kakhulu komoya

Ukuphatha kakhulu komoya

Iplastiki yamaphetha yesikhathi esiqiniswe ngokuqala lalayisiza indlela elungileyo lokuhlola ukusuka komoya kwiqhakamshana lezilondolozi. Izinkinga ezintsha ezazaliswa nge-$0.50 phandle kwesikhashana sifuti zihlola umoya omncane, ngakho ke iziphalizi zezinsuku ($1.00-1.75 phandle kwesikhashana sifuti) zingavumeleyo iindlela zakuhlatywa komoya okuthuthukisiwe ngokwesikhatsi. Amaphetha amahluke ayishumi nge-$2.00-2.50 phandle kwesikhashana sifuti azihlola iindlela yokubheka kwe-infrared, uzame ukulindela imali yokushisa ngeminyaka engaphezulu. Ukusetyenziswa kwezi nkinga zeziqinile ziyathatha ukuthi amaxhewha akhetha amandla aphoqweni abo ngokubhekisisa ukusuka komoya ngokuncane.

Umbiko wokuphakamisa okuhlala kwezilondolozi zezimpahla ezinhlalakahle zokusebenza kwesikhumba esikhulu sive ephakamiswa ngendlela yobungakanani bazo nokuhlola ukuba bayenza nini. Izifayela ezidingiweyo ze-polyethylene, ngokushesha bayenziwa, zingabizwa ngokwesikhashana esisodwa-esisibini. Iziphiwo ezintathu ezidinga iimfanelo yokuthuthukiswa kwe-UV kunye nezinto ezinethengiselwa, zihamba izinyanga ezimbili-kuzimbini ngokubanjulileyo. Izindlela ezindala ezinethengiselwa, ngaphandle kokuthi bazixhaswe amakhono, zihamba izinyanga ezine-ezintlanu kunye nokufakelwa okungakuvunyelwe yomthwalo womphilo kunye nokuhlobene nokugcina olungaphezu kwezinto ezithile. Umbiko wokuqala wesikhatsi lokuhlala lavelisa abasebenzisi ukuba babeke kuhlanganiswa ngokukhululekile ngokwesikhashana sesiphumo sokudla kunye nokusetyenziswa komtheleli.

Inkonzo yokugcina Ukuso lwemoto

Umbuso wokuphucumisa kwezilondolozi lezintsha zegcini liphikisana nesibonelo esidingayo lokusebenza nokuhlola kuhlu kwezinhlobo. Izixhobo ezinethile zingabizwa ngokulandelayo, zingavumelela ukuhlola okulandelayo, ngaphandle kokuthi izixhobo ezimenzekayo zikhona nezinto ezincediseyo lokuhlola okubizwa ngokulandelayo ezingabizela ukusuka komoya kanye nokuvumela umdabululo wesigodlo esihle. Iziphiwo ezindala zingavumelela izindlela ezincane zokusetyenziswa kwespekutramu sokuphucuma (PAR) phakathi komoya omkhulu kunye nokuphucuma komoya omkhulu. Loluqukumbuzo olungakhulu lokusebenzisa kulandela amaxheli akuyazi ukuba ziyahlola ngezinto ezithunyelweyo kanye nokugcina imibono yokusebenza.
