I-greenhouse kwilizwe okanye kwintsimi ivumela umnini ukuba avune kwangaphambili kunokuba avela kwiibhedi kwindawo evulekile. Ukongeza kwisidima sesakhiwo sinokubaluleka kunye nexesha elide lokuvelisa isivuno. Yingakho abaninzi abalimi beloli banquma ukunyuka imifuno kunye nemifino kwi-greenhouse . Abaninzi bafumana isakhiwo esenziwe ngokulungelelanisa imali eninzi, ngendlela. Kodwa unokwenza i-greenhouse ngezandla zakho, okuqinisekileyo, eziya kunciphisa kakhulu inkunkuma engcolileyo. Kwaye kwindlela, enye yezinto ezibalulekileyo iindawo zokugqoka. Ngokudla kaninzi kule mgangatho, ifilimu isetyenzisiweyo-izinto ezincinci kwaye zikulungele, kwaye kwezinye iimeko zihlala zihlala zihlala zihlala zihlala. Ukuba ucinga malunga nendlela yokugubungela isakhelo sokubumba kunye nokucinga ngako, siya kukuxelela ukuba yiyiphi ifilimu engcono kwi-greenhouse kunye nawuphi na ongakhethayo.
Ifilimu yezityalo zokugcina izityalo - njani ukhetha?
Ukuze i-futurehousehouse yakho iphumelele ukufeza imisebenzi yayo, ifilimu kufuneka ibe nepropati ezilandelayo, ezi:
- engenawo amanzi;
- obala;
- elastic;
- ukuchasene nokushisa;
- phefumula;
- ukusabalalisa ukukhanya.
Ngokuqinisekileyo, ngenxa yeli fomu ifilimu ye-polyethylene eqinile ifanelekile, eyona nto ifaneleke kakhulu. Kodwa ingaba neentlobo ezahlukileyo, nganye kunye neempawu zayo, njengoko kuya kuxoxwa ngezantsi.
Iindidi zefilimu ye-polyethylene zokugcina izityalo
Kuzo zonke iindidi zefilimu ezithengiswa kwimarike, zinamandla kakhulu, zintathu kuphela iintlobo:
- kuqiniswa;
- elide;
- i-polyvinyl chloride.
Ifilimu eqinisekisiwe yeendawo zokugcina izithombo yindawo enezintlu ezinomsila okhethiweyo we-honeyprob (fr) i-polypropylene okanye i-fiberglass. Loo mfilimu, nangona unamandla (ukhonza iminyaka engama-2-3), kodwa unobunzima obuphantsi.
Ifilimu ye- polyethylene eqhotyoshelweyo yokugcina izityalo kunye neendawo zokugcina izityalo yindlela encinci kakhulu kwimarike. Ikhonza ezo zinto zingekho ngaphezu kwexesha elilodwa, kodwa zithandwa ngabahlali basehlobo bezoqoqosho.
Ifilimu ye-Polyvinyl chloride , ngokusoloko ikhumbuza i-cellophane, ithathwa njengenye yezinto ezizinzileyo. Izinto ezinjalo zinomlinganiselo wokudlulisa ukukhanya okuphezulu - kungekhona ngaphantsi kwama-90%. Ukongeza, ifilimu ye-polyvinyl i-chloride ikwazi ukugcina ngaphezulu kwe-90% ye-infrared kunye ne-80% yemitha ye-ultraviolet. Esi sigqubuthelo sifanelekile kwiimeko apho kunenjongo yokugcina xa kushisa i-greenhouse.
Ifilimu engapheliyo yokushisa i-greenhouse iqela elikhulu lezinto zokwenza iindawo zokugcina izityalo ezihlukeneyo, ezininzi zazo zenziwe nge-polyethylene kunye nezinye izongezo zokuphucula izakhiwo. Ngokomzekelo, ifilimu ezinzileyo yokugcina izityalo zihluke kwizinto eziqhelekileyo ekubumbeni kwayo kubandakanya izinto ezizodwa. Siyabulela kwesi sihlomelo, izinto zixhatshazwa yi-UV kwaye ngoko zonakaliswa ngokukhawuleza ngenxa yokukhanya kwelanga. I-subspecies yayo, ifilimu emnyama neyemhlophe yamagumbi okugcina izityalo, zifakwe ngapha nangapha emhlophe, kwelinye - emnyama. Ngenxa yolu hlobo, umnyama omnyama uthatha ukushisa kwelanga, kunye nomgca omhlophe, ngokuchaseneyo, ubonisa oko. Enyanisweni, izinto ezinjalo zisetyenziswe njengengubo ebusweni bomhlaba kwi-greenhouse
Ifilimu efihliweyo ye-hydrophilic ikuvumela ukuba ulahlekise into enjalo, uphawu lwezityalo zokugcina izityalo, njengento yokuvuthwa kusasa kummandla ongaphakathi. Amaconsi amanzi aphelisa nje ifilimu. Kwifilimu emininzi yeminyaka emininzi, i- additive ivimbela ukubonakala komthunzi phezu komhlaba. Ifilimu yokugcina umlilo igcina ubushushu ngenxa yokuba i-composition ayiyi kudlula imilayezo ye-infrared. Ifilimu ye -bubble yomoya-moya yendawo yokugcina izityalo yindlela yokwakheka kwamathathu: uluhlu lwangaphakathi lwamabhobho emoyeni lujikelezwe kumacala amabini ngefilimu evulekileyo. Olu luyilo lukhuseleka ngamanzi kwaye lukhuselekile ngeqabunga.
