Umthi weti sisityalo somthi esingapheliyo: unomjikelo wophuhliso olupheleleyo kubomi bawo kunye nomjikelo wonyaka wokukhula kunye nokuphumla unyaka wonke. Umjikelo ngamnye womthi weti mawuthenwe kusetyenziswa aumatshini wokuthena. Umjikelo wophuhliso uwonke uphuhliswa ngokwesiseko somjikelo wophuhliso wonyaka. Umjikelo wophuhliso wonyaka ukhawulelwe ngumjikelo opheleleyo wophuhliso kwaye uphuhla ngokwemithetho yophuhliso olupheleleyo.

Ngokweempawu zokukhula kunye nokusetyenziswa okusebenzayo kwemveliso yemithi yeti, imithi yeti ihlala yohlulwe yangamaxesha amane ebhayoloji, angala, inqanaba lezithole, inqanaba lolutsha, inqanaba labantu abadala kunye nenqanaba lokuthomalalisa.

1.Inqanaba lezithole zomthi weti

Ngokuqhelekileyo iqala ngokuntshula kwembewu okanye ukusinda kwezithole zokusika, ukuvela kwezithole zeti, kunye nokuphela kokuyeka ukukhula kokuqala. Ixesha eliqhelekileyo ngunyaka omnye, kwaye ugxininiso lolawulo ngeli xesha kukuqinisekisa unikezelo lwamanzi, ukugcinwa kokufuma, kunye nomthunzi.

2.Inqanaba lolutsha lomthi weti

Ixesha elisuka ekuyekeni kokukhula kokuqala (ngokuqhelekileyo ebusika) ukuya kwimveliso esemthethweni yemithi yeti ibizwa ngokuba yi-juvenile period, ehlala i-3 ukuya kwi-4 iminyaka. Ubude beli xesha buhambelana ngokusondeleyo nenqanaba lokulima kunye nokulawula kunye neemeko zendalo. Inqanaba lolutsha lomthi weti lelona xesha leplastiki enkulu. Ekulimeni, kuyimfuneko ukuthena nge-fixediti prunerukuthintela ukukhula okuya phezulu kwesiqu esingundoqo, ukukhuthaza ukukhula kwamasebe asecaleni, ukulima amasebe omqolo owomeleleyo, kwaye wenze ukumila komthi oxineneyo. Ngelo xesha, umhlaba kufuneka ube nzulu kwaye ukhululeke ukuze inkqubo yeengcambu isasazwe nzulu kwaye ibanzi. Musa ukukhetha kakhulu amagqabi eti ngeli xesha, ngakumbi kwiminyaka emibini yokuqala yobuntwana. Zama ukunqanda ukukha amagqabi eti.

3.Ukukhula komthi weti

Ixesha labantu abadala libhekisa kwixesha elisusela xa umthi weti ufakwa ngokusemthethweni kwimveliso ukuya kwixesha lokuqala ulungiswa. Ikwabizwa ngokuba lixesha labantu abadala abancinci. Eli xesha linokuhlala iminyaka engama-20 ukuya kwengama-30. Ngeli xesha, ukukhula komthi weti kunamandla kakhulu, kwaye isivuno kunye nomgangatho ziphezulu. Imisebenzi yokulawula ukulima ngeli xesha ubukhulu becala kukwandisa ubomi beli xesha, ukomeleza ulawulo lokuchumisa, ukusebenzisa iintlobo ezahlukeneyo zezityalo.umatshini wokusika ukutshintsha ulwakhiwo olukhanyayo kunye nolwakhiwo olunzulu, ukuqoqosha umphezulu wesithsaba, kunye nokususa izifo kunye nezinambuzane ezonakalisa isithsaba. Amasebe, amasebe afileyo kunye namasebe abuthathaka. Kwinqanaba lokuqala lokukhula, oko kukuthi, inqanaba lokuqala lokuvelisa, ingqalelo kufuneka ihlawulwe ekuhlakuleleni isithsaba somthi ukuze ikwazi ukwandisa ngokukhawuleza indawo yokukha.

4. Ixesha lokuguga

Ixesha elisusela kuhlaziyo lokuqala lwendalo lwemithi yeti ukuya ekufeni kwesityalo. Ixesha le-senescence yemithi yeti lihlala lihlala amashumi eminyaka, kwaye linokufikelela kwikhulu leminyaka. Imithi yeti ye-Senescent isenakho ukuvelisa amashumi eminyaka yesivuno ngokuhlaziywa. Xa umthi weti umdala kakhulu kwaye isivuno asikwazi ukunyuswa emva kwabaninziumatshini wokusika ibrashiuhlaziyo, umthi weti kufuneka uphinde utyalwe kwangexesha.
