Kutentha Kwambiri ndi Kuwala

Pankhani yosankha kusinthanitsa ndi wowonjezera kutentha mumakhala ndi zisankho zitatu: galasi kapena pulasitiki (fiberglass, polycarbonate, filimu ya polyethylene). Chosankha chabwino kwambiri chimadalira momwe mungayankhire ndalama zowonjezera zosowa zanu komanso momwe mungathe kulipira. Nazi zina zabwino ndi zoyipa kuziyeza pozisankha zowonjezera kutentha kwanu.

Galasi

Galasi ndi yokongola, koma yosayenerera kutentha ( .95 R ) ndi yosweka mosavuta.

Iyenera kukhala mphamvu ziwiri kapena zitatu kuti zikhale zothandiza.

Zina zowononga galasi:

• Sizimapangitsa kuwala ndipo zimawotcha zomera.
• Zimakhala zolemetsa ndipo zimafuna chimango cholimba, maziko ndi ang'onoang'ono, mapepala ambiri.
• Zingakhale zokwera, chifukwa cha kuchuluka kwa mapepala ndi ziwalo.
• Kuwongolera kumafunika kukhala ndizomwe mwangwiro komanso kolimba. Mwina mungafune kuti pulogalamuyi ipange.

Pulasitiki

Chipangizo cha pulasitiki chotchedwa greenhouse, chimaphatikizapo: fiberglass, polycarbonate, filimu ya polyethylene ndi njira iliyonse yomwe amadza nayo. Zonse zimakhala zowala komanso zowonongeka kusiyana ndi galasi, kotero zimatha kubwera m'magulu akuluakulu kapena mapepala akuluakulu, kuchepetsa zojambula ndi kupanga zomangamanga mosavuta.

Galasilasi

Galasilasi sichimveka bwino, koma pafupifupi kuwala kwakukulu kumapanga magalasi a fiberglass monga magalasi ogulitsira magalasi. Kuwala kumaphatikizidwa ndipo magalasi otchedwa fiberglass omwe amagwiritsidwa ntchito pa greenhouses amapatsidwa malaya a gel opangira kutetezedwa kwa UV. Zimakhalabe bwino kuposa magalasi ndipo zimapangitsa kuti anthu azikhala osungunuka bwino.

(.83 R) Galasilasi ndi yabwino yoyamba kutentha ndipo ingakhale yokwanira kwa mlimi amene akufuna malo oti ayambe mbewu kumayambiriro kwa masika.

Ziphuphu zikuphatikizapo:

• Kuteteza kwa gelisi kumawotha pambuyo pa zaka zisanu ndi chimodzi ndipo zimasanduka chikasu
• Zovuta kuti zitsimikizidwezo zithe kugwirizana bwino
• Kuwongolera kovuta kuyeretsa ndi mawonekedwe odetsedwa kumatanthauza kuchepa pang'ono

Polycarbonate

Polycarbonate imakhalanso ndi pulasitiki yokhazikika, koma imakhala yosaoneka ngati galasi ndipo imagwiritsidwa ntchito pazitsamba zobiriwira. Amakhalanso yaitali, mpaka 2-3 nthawi yaitali kuposa fiberglass.

Mudzapeza polycarbonate imodzi, iwiri (1.4 - 1.9 R), ndi katatu (2.5 R).

Dothi lokha limodzi polycarbonate ndi losavuta kwambiri ndipo limapangitsa maonekedwe owoneka bwino kwambiri. Komabe zimapereka kuchepa kochepa kusungirako, kuwala kochepa ndi mphamvu kuposa zomwe zimawombera abale.

Ma polycarbonate aŵiri ndi atatu omwe amachititsa kuti tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda zimapangitsanso kusungunula bwino chifukwa cha mapepala apakati pa mpanda Zimakhalanso zodula, koma mumasunga ndalama zotentha. Phindu lina la polycarbonate ndilo moyo wake wa zaka 1515 m'madera ambiri. Ngati mutakhala ndi zomera zowonongeka kapena kuyesa kulima masamba onse m'nyengo yozizira komanso kuthamanga kwa wowonjezera kutentha kuchokera kugwero, polycarbonate ndiyo yabwino kwambiri.

Mafilimu a polyethylene

Mafilimu a polyethylene ndi njira yamakono yotsika mtengo kwa wamaluwa omwe amagwiritsa ntchito wowonjezera kutentha kwa mbewu makamaka kuyambira. Zimabwera m'mapepala omwe angagwiritsidwe ntchito pamagulu awiri kapena awiri, kuti asungidwe bwino. (.85 - 1.4 R) Zimagwira ntchito bwino, koma sizakhala nthawi yayitali, mwinamwake zaka 2-4, malinga ndi zomwe zagulitsa komanso nyengo.

Alimi ogulitsa monga choncho chifukwa ndi otchipa, amapereka kusinthasintha ndipo ali ndi antchito oti azibwezeretsa zaka zingapo. Mafilimu a polyethylene amagwira ntchito bwino ngati muli ndi malo awiri okhala ndi mpweya pakati.
