Iingenelo zeZindlu zeFilimu eziNcinci zezoLimo zanamhlanje
Kwiminyaka yakutshanje, ii-greenhouse zefilimu zeMulti-SpanZifumene ingqwalasela enkulu kwishishini lezolimo ngenxa yokusebenza kwazo kakuhle ekukhuthazeni iindlela zokulima ezizinzileyo. Ezi zakhiwo, eziphawulwa zii-span ezininzi ezidibeneyo, zibonelela ngendawo efanelekileyo yokulima iintlobo ngeentlobo zezityalo, ukusuka kwimifuno ukuya kwiintyatyambo. Ukusetyenziswa kwefilimu ye-polyethylene njengezinto zokugquma kuphucula ukuhanjiswa kokukhanya, ngelixa kukwabonelela ngobushushu obufunekayo, nto leyo eyenza ukuba zibe lukhetho oludumileyo phakathi kwabalimi.
Enye yezona zibonelelo ziphambili ze izakhiwo zefama yesinyithi yikhono lazo lokwenza ngcono iimeko zokukhula kwezityalo. Uyilo luvumela ukujikeleza komoya okuphuculweyo kunye nokulawulwa kobushushu, okubaluleke kakhulu kwizityalo ukuze zikhule. Ngokusebenzisa izikrini zobushushu kunye neenkqubo zokungenisa umoya, ezi greenhouses zinokugcina amanqanaba aphezulu okufuma kunye nokunciphisa ukuguquguquka kobushushu, ukuqinisekisa ukuba izityalo zifumana ukhathalelo eziludingayo ngamaxesha ahlukeneyo onyaka.
Ukongeza, uyilo lwe izakhiwo zefama zesakhelo sentsimbi ivumela ukusetyenziswa kwendawo ngokufanelekileyo. Ulwakhiwo oludibeneyo luvumela ukukhulaukuze kwandiswe indawo ekhula kuyo ngaphandle kokunciphisa ukufikelela. Oku kuluncedo ngakumbi kwiindawo apho umhlaba olimekayo unqongophele khona, njengoko kwenza kube lula ukuvelisa isivuno esiphezulu kwindawo encinci. Ngaphezu koko, indlela ezi greenhouse ezikhula ngayo ithetha ukuba zinokwandiswa okanye zitshintshwe lula ukuze zilungele iintlobo ezahlukeneyo zezityalo okanye iindlela zokukhulisa.
Ukusetyenziswa kwefilimu njengento yokugquma nako kunegalelo ekongeni iindleko. Iifilimu zepolyethylene zilula kwaye azibizi kakhulu, kodwa zibonelela ngokhuseleko oluhle kakhulu kwizinto ezingqongileyo ezifana nomoya, imvula, kunye nezinambuzane. Oku kufikeleleka kuvumela abalimi ukuba batyale imali kwitekhnoloji eyongezelelweyo kunye neendlela eziphucula imveliso ngakumbi, njengeenkqubo zokunkcenkceshela ezenzekelayo kunye nezixhobo zokulima ezichanekileyo.
Ngaphezu koko, izakhiwo zezolimo zesinyithi Zinokuguquguquka kakhulu ekusetyenzisweni kwazo. Zingasetyenziselwa ukulima ngendlela yendalo, i-hydroponics, okanye iindlela zemveli zokukhulisa ezisekelwe emhlabeni. Olu kuguquguquka kuzenza zifaneleke kwiintlobo ngeentlobo zezityalo, zilungiselela iindlela ezahlukeneyo zolimo kunye neemfuno zemarike. Njengoko abathengi besiya befuna imveliso ekhuliswe ngendlela ezinzileyo, ukukwazi ukulawula izinto ezingqongileyo kwezi greenhouse kunokukhokelela kwisivuno esisemgangathweni ophezulu esihlangabezana nemigangatho yemarike.
Okokugqibela, iingenelo zokusingqongileyo zeMulti-Span film greenhouses azinakulibaleka. Ngokudala imeko-bume elawulwayo, ezi zakhiwo zinokunciphisa imfuneko yokufaka iikhemikhali kunye nokusetyenziswa kwamanzi ngokugqithisileyo, zikhuthaze iindlela zokulima ezinobuhlobo nokusingqongileyo. Oku kuhambelana nomkhwa okhulayo wokulima okuzinzileyo, apho ukunciphisa umngcipheko wendalo ngelixa ukwandisa imveliso kubaluleke kakhulu.
Ukuqukumbela, ii-Multi-Span film greenhouses zimele indlela yokutshintsha kwezolimo zanamhlanje. Ngokudibanisa ukusebenza kakuhle, ukuguquguquka, kunye nokuzinza, zinika amandla abalimi ukuba bazivumelanise neemfuno zezolimo ezitshintshayo ngelixa bephucula imveliso kunye nomgangatho. Njengoko ishishini liqhubeka nokukhula, ezi greenhouses zidlala indima ebalulekileyo ekusombululeni imingeni yokhuseleko lokutya kunye nokuzinza kokusingqongileyo.
