Ukwamkela iKamva lezoLimo: ukuTshintsho kunye nokuSetyenziswa kweFilm Greenhouses ezineNkqubo yokuPholisa eMzantsi Afrika

Njengoko utshintsho lwemozulu kwihlabathi luqhubeleka ukuba lubi, ezolimo eMzantsi Afrika zijongene nemingeni engazange ibonwe ngaphambili. Ingakumbi ngexesha lasehlotyeni, amaqondo obushushu angaphezu kwama-40°C awathinteli nje ukukhula kwesityalo kodwa anciphisa kakhulu umvuzo wamafama. Ukoyisa lo mba, indibaniselwano yezindlu zefilimu kunye neenkqubo zokupholisa ibe sisisombululo esithandwayo nesisebenzayo kumafama aseMzantsi Afrika.
Iindawo zokuhlala zefilimu zezinye zezona ntlobo zegreenhouse ezisetyenziswa kakhulu eMzantsi Afrika ngenxa yokufikeleleka kwazo, ukwakhiwa ngokulula, kunye nokuhanjiswa kokukhanya okugqwesileyo. Ifilimu ye-polyethylene iqinisekisa ukuba izityalo zifumana ukukhanya kwelanga okwaneleyo ngelixa zikhusela kwimozulu yangaphandle. Noko ke, ngexesha eligqats’ ubhobhoyi ehlotyeni laseMzantsi Afrika, iindawo zokugcina izityalo ezifuywayo zinokutsha ngokugqithisileyo, nto leyo ebangela ukuba izityalo zisokole.
Ukongezwa kwenkqubo yokupholisa kwii-greenhouses zefilimu kusombulula le ngxaki. Amakhethini amanzi, adityaniswe neefeni, abonelela ngendlela esebenzayo yokupholisa umphunga enciphisa iqondo lobushushu ngaphakathi kwi-greenhouse. Le nkqubo iqinisekisa ukuba amaqondo obushushu kunye nokufuma kuhlala kuluhlu olufanelekileyo lokukhula kwesityalo, ikhuthaza ukukhula okusempilweni, okufanayo nakubushushu obugqithisileyo.
Ngokudibanisa iinkqubo zokupholisa kwizindlu zabo zefilimu, amafama aseMzantsi Afrika anokulima izityalo ezikumgangatho ophezulu nakwiinyanga ezishushu zasehlotyeni. Izityalo ezifana neetumato, iikomkomere kunye neepepile zikhula kakuhle kwindawo ezinzileyo, kunye neengozi ezincitshisiweyo zomonakalo okanye ukuhlaselwa kwezinambuzane. Oku kukhokelela kwizivuno eziphezulu, imveliso ekumgangatho ongcono, kunye nokuphuculwa kokhuphiswano lwemarike.
Indibaniselwano yezindlu zefilimu kunye neenkqubo zokupholisa ziguqula ikamva lezolimo eMzantsi Afrika. Ngokubonelela ngesisombululo esifikelelekayo, esisebenzayo, kunye nesizinzileyo, obu bugcisa bunceda amafama ukuba aqhelane nemingeni yemozulu, eqinisekisa ukuba ezolimo ziyaqhubeka zikhula eMzantsi Afrika kwiminyaka ezayo.
