M'gawo laulimi lomwe likusintha mosalekeza, kusankha kwa zida kumathandizira kwambiri kuti pakhale zokolola komanso zogwira mtima. Pakati pa zipangizozi, mapaipi a PVC (polyvinyl chloride) atulukira ngati osintha masewera, zomwe zimakhudza kwambiri ulimi wothirira, kusamalira mbewu, ndi ntchito zaulimi.
Chimodzi mwazinthu zabwino zoyambiraZithunzi za PVCmu ulimi ndi opepuka ndi kusinthasintha chikhalidwe chawo. Mosiyana ndi mapaipi a rabara achikhalidwe,Zithunzi za PVCndizosavuta kunyamula ndi kunyamula, zomwe zimapangitsa alimi kukhazikitsa njira zothirira mwachangu komanso moyenera. Kusinthasintha kumeneku kumakhala kopindulitsa makamaka m'magawo akuluakulu komwe kuwongolera ndikofunikira. Alimi atha kuyikanso mapaipi kuti agwirizane ndi kusintha kwa mbeu kapena kubzala kwa nyengo, kuwonetsetsa kuti madzi agawidwa bwino.
Komanso,Zithunzi za PVCamalimbana kwambiri ndi nyengo, kuwala kwa UV, ndi mankhwala omwe amagwiritsidwa ntchito kwambiri paulimi. Kukhazikika kumeneku kumatanthauza kuti amatha kupirira zovuta zogwiritsidwa ntchito panja popanda kunyozeka pakapita nthawi. Alimi akhoza kudaliraZithunzi za PVCnjira zothetsera ulimi wothirira kwa nthawi yayitali, kuchepetsa kufunika kosinthidwa pafupipafupi ndi kukonza. Kudalirika kumeneku kumatanthauza kupulumutsa ndalama komanso kutsika pang'ono, zomwe zimapangitsa alimi kuganizira kwambiri ntchito zawo zazikulu.
Zotsatira zaZithunzi za PVCchimapitirira kupitirira ulimi wothirira. Amagwiritsidwanso ntchito pazaulimi zosiyanasiyana, kuphatikiza kunyamula feteleza, mankhwala ophera tizilombo, ndi zakumwa zina zofunika. The chemical resistance ofZithunzi za PVCimawonetsetsa kuti zinthuzi zitha kunyamulidwa bwino popanda chiopsezo cha kuipitsidwa kapena kulephera kwa payipi. Kuthekera kumeneku n'kofunika kwambiri kuti mbeu zisamayende bwino komanso kuti alimi azigwiritsa ntchito bwino chithandizo chamankhwala.
Komanso, kugwiritsa ntchitoZithunzi za PVCzimathandizira pa ntchito yoteteza madzi pa ulimi. Ndi kutsindika kwaulimi wokhazikika, njira zothirira bwino ndizofunika kwambiri kuposa kale lonse.Zithunzi za PVCZitha kuphatikizidwa mumayendedwe amthirira, omwe amapereka madzi mwachindunji ku mizu ya mbewu, kuchepetsa zinyalala komanso kukulitsa luso. Njirayi imateteza madzi komanso imalimbikitsa kukula kwa mbewu zabwino.
Pomaliza, zotsatira zaZithunzi za PVCpa gawo laulimi ndi lozama. Makhalidwe awo opepuka, olimba, ndi osamva mankhwala amawapangitsa kukhala chida chamtengo wapatali paulimi wamakono. Pomwe makampaniwa akupitilizabe kukumbatira njira zatsopano zothanirana ndi vutoli,Zithunzi za PVCmosakayika adzakhala ndi gawo lofunikira kwambiri pakukonza tsogolo laulimi.
