Njengoba imithombo yamanzi yomhlaba wonke iya iqina, ubuchwepheshe bokunisela ngenkasa kwezolimo bubhekene nezinguquko ezishintshayo. Ucwaningo lwakamuva lubonisa ukuthi uhlelo lokunisela olunembayo olusekelwe eziteshini zezulu zezolimo ezihlakaniphile lungasiza abalimi ukuba bathole inzuzo enkulu yokongiwa kwamanzi ngo-30% kanye no-20% okhuphule umkhiqizo. Lobu buchwepheshe obusha buchaza kabusha amazinga okunisela ezolimo zesimanje.
Iziteshi zesimo sezulu ezihlakaniphile zingaba kanjani “ubuchopho obuhlakaniphile” bendawo yokulima
Emapulazini esimanje, iziteshi zesimo sezulu zezolimo seziphenduke imishini ehlakaniphile ebaluleke kakhulu.
Umgomo wobuchwepheshe: Ukwenza izinqumo okunembayo okuqhutshwa yidatha
Isiteshi sesimo sezulu esihlakaniphile sezolimo siqoqa idatha yesikhathi sangempela ngendawo yasemapulazini sisebenzisa izinzwa eziningi, okuhlanganisa izingxenye ezibalulekile ezifana “nenzwa yomswakama womhlabathi”, “imonitha yemvula”, “isivinini somoya kanye nemitha yesiqondiso”, “inzwa yemisebe esebenzayo ye-photosynthetically” kanye “nokuhlola izinga lokushisa nokuswakama”.
“Ukunisela ngenkasa ngokwesiko kuvame ukusekelwe kokuhlangenwe nakho kunokuba kusekelwe emininingwaneni,” kusho uProfesa Zhang, uchwepheshe wezokulima wesimo sezulu. "Kodwa-ke, iziteshi zesimo sezulu ezihlakaniphile zingahlinzeka ngemininingwane yemvelo enembile ku-square meter, zitshele abalimi ukuthi banisele nini 'nokuthi' banisele malini ', ukufeza ukuhlinzekwa kwamanzi lapho kudingeka ngempela."
Umphumela wohlelo lokusebenza uyamangalisa
Esizindeni sokutshala imifino eThailand, impumelelo emangalisayo yenziwe ngemva kokwamukelwa kwesistimu yesiteshi sezulu esihlakaniphile. "Phambilini, besinisela ngomuzwa, kodwa manje sithembele kudatha," kusho u-Master Li, umlimi omkhulu. "Lolu hlelo lwenza kube lula ukuthi kusetshenziswe isikhathi kanye nenani lokuchelela. Ekupheleni konyaka, sesiyilondolozile ingxenye eyodwa kwezintathu yesikweletu samanzi, kanti isivuno senyuke ngo-20% esikhundleni salokho."
Idatha ibonisa ukuthi i-mu ngayinye yomhlaba kulesi sisekelo yonga cishe ama-cubic metres angu-120 wamanzi ngonyaka, ukukhishwa kwemifino kukhuphuka ngo-15% kuya ku-20%, futhi ikhwalithi nayo ithuthuke kakhulu.
Umqondisi u-Wang we-Technology Extension Centre yoMnyango Wezolimo waveza: “Ngokwehla kwezindleko zokuzwa izinzwa nokuthandwa kobuchwepheshe be-Internet of Things, iziteshi zesimo sezulu ezihlakaniphile zisabalala zisuka emapulazini amakhulu ziye kubalimi abancane nabaphakathi.” Uhulumeni uphinde walusheshisa lolu hlelo ngezinqubomgomo zoxhaso ukuze kusekelwe ezolimo ezonga amanzi kanye nesu lokuvikela ukudla likazwelonke.
Ikusasa Outlook
Ngokuhlanganiswa kwe-5G, ubuhlakani bokwenziwa kanye nobuchwepheshe bekhompuyutha yamafu, iziteshi zesimo sezulu zezolimo zithuthukela ekuhlakanipheni okukhulu nokunemba. Ochwepheshe babikezela ukuthi phakathi neminyaka emithathu ezayo, izinga lokunisela elihlakaniphile likazwelonke kulindeleke ukuthi likhuphuke lisuka ku-15% lamanje liye ngaphezu kwama-40%, linikeze ukwesekwa okubalulekile kwezobuchwepheshe ukuze kuqinisekiswe ukutholakala kokudla kuzwelonke kanye nokusetshenziswa ngokuqhubekayo kwemithombo yamanzi.
