Ngaphansi kwesizinda sentuthuko esheshayo yezolimo kulezi zinsuku, ukuqapha nokuphatha ikhwalithi yenhlabathi kube yisixhumanisi esibalulekile sokwandisa isivuno sezitshalo nokwandisa ukwabiwa kwezinsiza. Ngokuthuthuka okuqhubekayo kobuchwepheshe, kuye kwavela izinzwa zomhlabathi, okuhlinzeka ngesisombululo esisha kubalimi nabaphathi bezolimo. Lesi sihloko sizokwethula isimiso sokusebenza, imisebenzi eyinhloko kanye namathemba okusetshenziswa kwezinzwa zomhlabathi kwezolimo, okuzokusiza uqonde kangcono inani lalobu buchwepheshe obusha.
Iyini inzwa yomhlabathi?
Inzwa yomhlabathi iyithuluzi elihlakaniphile elisetshenziselwa ukuqapha imvelo yomhlabathi ngesikhathi sangempela. Ingaqoqa idatha ehlukahlukene enhlabathini, okuhlanganisa umswakama wenhlabathi, izinga lokushisa, inani le-pH, ukuhanjiswa kukagesi kanye nokuqukethwe kwezakhamzimba, njll. Lezi zinzwa zixhunywe ohlelweni lokuphatha ngokuxhumana okungenantambo, okuvumela abalimi ukuthola ulwazi ngezimo zenhlabathi noma nini nanoma kuphi, ngaleyo ndlela benze izinqumo zesayensi.
2. Imisebenzi eyinhloko yezinzwa zomhlabathi
Ukuqapha kwesikhathi sangempela
Izinzwa zomhlabathi zingasebenza ngokuqhubekayo amahora angama-24, zithole izinguquko zesikhathi sangempela ezinkomba ezahlukahlukene zomhlabathi, zisize abalimi baqonde ngokushesha izimo zomhlabathi futhi bagweme ukulahlekelwa okubangelwa ukubambezeleka kolwazi.
Ukuhlaziywa kwedatha
Izinzwa eziningi zenhlabathi zihlonyiswe ngemisebenzi enamandla yokuhlaziya idatha, engahlaziya futhi icubungule idatha eqoqwe ukuze ikhiqize imibiko ebonakalayo, okwenza abalimi babe nokuqonda okunembile ngesimo sempilo yenhlabathi.
I-alamu ezenzakalelayo
Uma izinkomba zenhlabathi zidlula ububanzi obubekiwe, inzwa ingakhipha i-alamu ngokuzenzakalelayo ukukhumbuza abalimi ukuthi bathathe izinyathelo ezifika ngesikhathi, njengokulungisa umthamo wokunisela noma izindlela zokufaka umanyolo, ukuvimbela ngempumelelo izitshalo ukuthi zingalimali.
Ukuqapha okukude
Ngocingo noma ngamakhompyutha, abalimi bangahlola idatha etholwa yizinzwa zenhlabathi nganoma yisiphi isikhathi, bafeze ukuqapha okude, futhi bonge isikhathi kanye nezindleko zabasebenzi zokuhlolwa endaweni.
3. Izinzuzo zezinzwa zomhlabathi
Khulisa isivuno sezitshalo
Ngosizo lwedatha yesikhathi sangempela, abalimi bangaphatha amanzi nezakhamzimba ngendlela efanele, bathuthukise ukusebenza kahle kokukhula kanye nesivuno sezitshalo.
Londoloza izinsiza
Ukufaka umanyolo kanye nokunisela okunembile kunganciphisa kakhulu ukumoshwa kwamanzi kanye nomanyolo wamakhemikhali, kwehlise izindleko zokukhiqiza kwezolimo, futhi kube nomthelela omuhle ekuvikelweni kwemvelo ngesikhathi esifanayo.
Thuthukisa ukuqina
Ngokuqapha isimo sempilo yenhlabathi, abalimi bangaqonda ngokushesha indawo yokukhula kwezitshalo zabo, bakhe amasu okuphatha afanele, futhi bathuthukise ikhono lezitshalo lokumelana nezinambuzane, izifo kanye nokushintsha kwesimo sezulu.
Sekela ezolimo ezisimeme
Izinzwa zomhlabathi zinikeza ukwesekwa kobuchwepheshe ukuze kufezwe intuthuko esimeme futhi zingasiza abalimi ukulinganisela kangcono izinzuzo zezomnotho kanye nokuvikelwa kwemvelo ekukhiqizeni.
4. Ukusetshenziswa kabanzi kwezinzwa zomhlabathi
Ezolimo ezinembile
Izinzwa zomhlabathi ziyithuluzi eliyinhloko lokulima okunembile, okusiza abalimi ukuthi bakhe izinhlelo zokuphatha ezenzelwe bona ngokusekelwe ezidingweni zangempela futhi bathuthukise ukusebenza kahle kokukhiqiza.
Ucwaningo lwesayensi kanye neMfundo
Emikhakheni yocwaningo lwezolimo kanye nemfundo, izinzwa zomhlabathi zisetshenziswa kabanzi ekuhlolweni nasekufundiseni, zinikeza abafundi nabacwaningi idatha yangempela kanye nezisekelo zokuhlola.
Ezolimo zasemadolobheni
Kwezolimo zasemadolobheni kanye nezolimo zomphakathi, izinzwa zomhlabathi zingasiza izakhamuzi zasemadolobheni ukuqonda izimo zomhlabathi ngesikhathi sangempela, zithuthukise ukuphathwa kwengadi yemifino, futhi zikhuthaze ukuthuthukiswa kwezindawo eziluhlaza zasemadolobheni.
Ukuqapha imvelo
Kuma-ejensi okuvikela imvelo, izinzwa zenhlabathi zingamathuluzi abalulekile okuqapha ukungcoliswa kwenhlabathi kanye nezinguquko, okusiza ekuhloleni isimo sempilo semvelo yemvelo kanye nokusekela imizamo yokuphathwa kwemvelo kanye nokubuyiselwa kwayo.
Isiphetho
Njengoba kugcizelelwa emhlabeni wonke ukuphepha kokudla kanye nentuthuko esimeme, amathuba okusetshenziswa kwezinzwa zomhlabathi angenamkhawulo. Akugcini nje ngokuthuthukisa ukusebenza kahle komkhiqizo wezolimo, kodwa futhi kuhlinzeka abalimi ngezindlela zokuphatha ezihlakaniphile nezesayensi. Ngokukhuthaza izinzwa zomhlabathi, masibambisane ukuze sifake isandla ekufezeni umkhiqizo wezolimo osebenza kahle futhi onobungane nemvelo.
Uma ufisa ukufunda kabanzi mayelana nezinhlelo zokusebenza ezithile noma ulwazi lokuthenga lwezinzwa zomhlabathi, sicela ukhululeke ukusithinta noma nini. Silangazelela ukusebenzisana nawe ukuze sakhe ikusasa eliqhakazile lezolimo ezihlakaniphile!
