Isicelo seMveliso
Ngokuveliswa kweepolymers ze-molecular-polyvinyl chloride kunye ne-polyethylene, iifilimu zeplastiki zisetyenziswa kakhulu kwezolimo.IJapan kunye namazwe aseYurophu nawaseMelika aphumelela ukusebenzisa ifilimu yegreenhouse ukugquma iihotbed ekuqaleni kweminyaka yee-1950, emva koko agquma iishedi ezincinane nezindlu zokugcina izityalo neziphumo ezihle.ilizwe lam lazisa ifilimu yezolimo ye-polyvinyl chloride ekwindla ka-1955. Yaqala ukusetyenziswa kwiishedi ezincinci zokugubungela imifuno eBeijing, eyafikelela umphumo wokuvuthwa kwangaphambili kunye nokwanda kwesivuno.I-greenhouse yayiyisixhobo esikhethekileyo sokuvelisa imifuno, kunye nokuphuhliswa kwemveliso, ukusetyenziswa kwe-greenhouse kuye kwanda kakhulu.Okwangoku, i-greenhouse isetyenziselwe ukulima iintyatyambo zeembiza kunye neentyantyambo ezisikiwe;ukuveliswa kwemithi yeziqhamo kusetyenziselwa ukulinywa kweediliya, amaqunube, iivatala, iivatala, iipesika, neeorenji;imveliso yamahlathi isetyenziselwa ukulima izithole zemithi kunye nemithi yokuhombisa;ishishini lokuzala lisetyenziselwa i-sericulture kunye nokufuya.Inkukhu, iinkomo, ihagu, intlanzi kunye nefry, njl.
