Ngokusho kwezikhungo zeNational National zokubikezela kwezemvelo, ngoJulayi 3 kwakuwusuku olushisa kakhulu ekurekhondweni emhlabeni jikelele, ngamazinga okushisa aphakathi emhlabeni we-degrees odlula ku-17 degrees Kodwa-ke, irekhodi lahlala isikhathi esingaphansi kwamahora angama-24, futhi laphuka futhi ngoJulayi 4, lifinyelela ngo-17.18 ° C. Ezinsukwini ezimbili nje kamuva, ngoJulayi 6, izinga lokushisa lomhlaba wonke laphinde lishaye irekhodi eliphakeme, ukwephula amarekhodi kuJulayi 4 no-5. Izinga lokushisa elijwayelekile lomhlaba ngaphezulu komhlaba lifinyelela ku-17.23 ° C.
Umthelela wokushisa okuphezulu ekukhiqizweni kwezolimo
Isimo sezulu esiphakeme sokushisa sinomthelela omkhulu ekukhiqizweni kwezolimo. Amazinga okushisa aphezulu phakathi nosuku azovimbela i-photosynthesis yezitshalo futhi anciphise ukuhlanganiswa kanye nokuqongelela ushukela, ngenkathi ebusuku kuzosheshisa izitshalo zokuphefumula futhi kuncishiswe izakhi zomzimba ezivela ezitshalweni kanye nekhwalithi.
Ukushisa okuphezulu kuzosheshisa ukuhwamuka kwamanzi ezitshalweni. Inani elikhulu lamanzi lisetshenziselwa ukuguquguquka nokushibilika kokushisa, ukucekela phansi ibhalansi yamanzi esitshalweni, okwenza lesi sitshalo siwuvuke futhi some. Uma kungenjalo waniselwa ngesikhathi, lesi sitshalo sizolahlekelwa kalula amanzi, somile futhi sife.
Izindlela zokuphendula
Usebenzisa amanzi ukuguqula izinga lokushisa elikhona kwezilimo kuyindlela elula kunazo zonke. Ngakolunye uhlangothi, ingaxazulula inkinga yokunisela, futhi ngasikhathi sinye, ingalungisa izinga lokushisa futhi linikeze indawo efanelekile ukukhula kwezitshalo.
1. Izilimo ezisenyakatho
Kunezindawo ezinkulu kakhulu zamapulazi asobala enyakatho, futhi akulungile ukusebenzisa umjondolo noma ukuthambisa okufakelwa kokupholisa. Lapho izilimo ezivulekile ezinjenge-corn, ama-soya, kanye nokotini zihlangana namazinga okushisa aphezulu ngesikhathi sokukhula okubucayi, kufanele aniselwe ngokufanele ukwehlisa izinga lokushisa komhlaba futhi akhuthaze ukufakwa kwamanzi ukuvikela umonakalo obangelwa ukuguquguquka kwamanzi amakhulu kunokufakwa kwezimpande.
Ezindaweni ezisenyakatho lapho ikhwalithi yamanzi icacile, amaphampu we-centrifugal ehlanzekile ehlanzekile angasetshenziswa ukusiza ukunisela kwezolimo. Iphampu ye-Self-Priming inesilinganiso esikhulu samanzi esitoreji emgodini kanye nezinga eliphakeme elithwala umthwalo we-inlet ye-water kanye ne-outlet. Kungathembela ekuzithembeni kwaso okuphezulu ehlobo lapho ilanga likhanya. Ukusebenza, kungangenisa masinyane amanzi omfula enkundleni, kusiza ukuthuthukisa isimo sezulu sendawo, futhi kuvikele izilimo kusuka ekushiseni okushisa ubuthi.

2.Izilimo eziseningizimu
Eningizimu, irayisi nama-yam kuyizitshalo eziphambili ehlobo. Lezi yizilimo ezidinga ukunisela ezinkulu zendawo. Akunakwenzeka ukusebenzisa i-greenhouse ukupholisa kulezi zilimo, futhi zingashintshwa kuphela ngamanzi. Lapho uhlangabezana namazinga okushisa aphezulu, ungathatha indlela yokunisela okuqhubekayo kwamanzi okunisela, usuku lokunisela kanye nokunisela ebusuku, okunganciphisa ngempumelelo amazinga okushisa ensimu futhi uthuthukise i-microclimate yensimu.
Umhlaba otshaliwe eningizimu uhlakazekile futhi imifula kakhulu iqukethe isilika kanye namatshe amatshe. Ngokusobala akufanelekile ukusebenzisa iphampu yamanzi ehlanzekile. Singazikhethela ipompo ye-seof-Priming Centrifugal Pump. Uma kuqhathaniswa nepompo yamanzi ehlanzekile, inomklamo wesiteshi esine-flow ebanzi futhi unekhono elinamandla lokuhambisa indle. Kufanele kukhethwe. I-Shaft yensimbi engagqwali yensimbi engama-304 ingathuthukisa ngempumelelo ukukhuthazela futhi ivumelane nezimo zokusebenza zasekuseni nasensimini endle. Emini, kwathulwa amanzi okufulawa kosuku lokusiza ukupholisa futhi angezele umthombo wamanzi odingekayo ekukhuleni. Ebusuku, amanzi amaningi asensimini akhishwa ngepompo ukugwema ukufa kwezimpande zezitshalo ngenxa yokuntuleka komoya-mpilo.
Eminyakeni yamuva nje, izinguquko ezedlulele esimweni sezulu seziye zaqhubeka zithinta ukukhiqizwa nokuphila. Zombili lezi zikhukhula nezikhukhula zenzeke kaningi. Indima yamaphampu wamanzi asevelele ngokwengeziwe. Bangakwazi ukukhipha amandla ngokushesha futhi banikeze ukunisela ngokushesha ukuvikela ezolimo futhi bathuthukise ukusebenza kahle kwezolimo.
