Greenhouse Agricultural Revolution ya ku South Africa: Kuphatikiza Kwabwino kwa Nyumba Zobiriwira Zobiriwira ndi Zozizira

Pamene kusintha kwa nyengo kukukulirakulira, ulimi ku South Africa kukumana ndi mavuto owonjezereka. Makamaka m'chilimwe, kutentha kotentha sikumangokhudza kukula kwa mbewu komanso kumapangitsa alimi kupanikizika kwambiri. Pofuna kuthana ndi nkhaniyi, kuphatikiza kwa nyumba zosungiramo mafilimu ndi njira zoziziritsira kwatuluka ngati njira yabwino yothetsera ulimi waku South Africa.
Malo osungiramo mafilimu ndi njira yabwino, yotsika mtengo, komanso yosavuta kuyiyika, yomwe imayenera kutengera nyengo ya ku South Africa. Amapangidwa kuchokera kumafilimu owoneka bwino kapena owoneka bwino a polyethylene, amaonetsetsa kuti kuwala kwadzuwa kokwanira mkati mwa wowonjezera kutentha, kupereka mbewu ndi kuwala koyenera. Pa nthawi yomweyo, permeability filimu kumathandiza kuti mpweya kufalitsidwa mkati wowonjezera kutentha, kuchepetsa kutentha buildup. Komabe, m’miyezi yotentha yachilimwe ku South Africa, kutentha kwa mkati mwa wowonjezera kutentha kungakwere kuposa mmene kulili koyenera, kutanthauza kugwiritsira ntchito njira yozizirirapo.
Kuphatikizidwa kwa dongosolo loziziritsa ndi mafilimu obiriwira amalola kusungirako kutentha kwabwino kwa kukula kwa mbewu, ngakhale pa kutentha kwakukulu. Alimi a ku South Africa amaika makina oziziritsira nsaru zonyowa ndi makina ozizirira kuti achepetse kutentha mkati mwa greenhouse. Makinawa amagwira ntchito pophatikiza makatani onyowa ndi mafani, omwe amawongolera kutentha ndi chinyezi, kuonetsetsa kuti malo okhazikika amathandizira kuti mbewu zikule bwino.
Kwa alimi, kuphatikiza kwa nyumba zosungiramo filimu ndi kuzirala sikumangowonjezera zokolola komanso kumapangitsa kuti mbeu zikhale bwino. Masamba ndi zipatso monga tomato, nkhaka, ndi sitiroberi zimakula mofulumira komanso mofanana m'malo omwe kutentha ndi chinyezi kumayendetsedwa. Kuphatikiza apo, makina oziziritsa amakhala osagwiritsa ntchito mphamvu, zomwe zimathandiza kuchepetsa ndalama zogwirira ntchito.
Pomaliza, kuphatikiza kwa nyumba zosungiramo mafilimu ndi njira zoziziritsira kwabweretsa mwayi waukulu wamabizinesi ndi kuthekera kwachitukuko ku ulimi waku South Africa. Sikuti zimangowonjezera phindu la alimi komanso zimalimbikitsa chitukuko chokhazikika chaulimi, zomwe zimapangitsa kukhala luso lamakono la ulimi wamtsogolo.
