ILima, ePeru— Eqhulwini elikhulu lemikhuba yezolimo ePeru, ukwethulwa kwezinzwa zekhwalithi yamanzi ze-pH kanye ne-oxidation-reduction potential (ORP) ezifakwe izikrini kuguqula indlela abalimi abaqapha futhi baphathe ngayo izinhlelo zabo zokunisela. Njengoba umkhakha wezolimo ubhekene nezinselelo ezimbili zokushintsha kwesimo sezulu kanye nokuntuleka kwamanzi, lezi zinzwa ezithuthukisiwe ziba amathuluzi abalulekile athuthukisa isivuno sezitshalo, athuthukise ukusebenza kahle kwezinsiza, futhi akhuthaze imikhuba yokulima esimeme.
Isidingo Sokusungula Izinto Ezintsha Kwezolimo zasePeru
Ezolimo zasePeru ziyahlukahluka, kusukela ezitshalweni zasezintabeni ezifana namazambane kanye ne-quinoa kuya emikhiqizweni yasogwini efana no-avokhado namagilebhisi. Kodwa-ke, lo mkhakha obalulekile usengozini enkulu yokushintshashintsha kokutholakala kwamanzi kanye nekhwalithi, okubhebhethekiswa ukuguquka kwesimo sezulu kanye nokuwohloka kwemvelo. Abalimi baye baphendukela kakhulu kubuchwepheshe ukuze babhekane nalezi zinselele, befuna izindlela ezisebenza kahle zokuthuthukisa ukusetshenziswa kwamanzi nokuqinisekisa izitshalo ezinempilo.
Indlela Izinzwa ze-pH ne-ORP Ezisebenza Ngayo
Izinzwa zekhwalithi yamanzi ezisanda kufakwa zilinganisa imingcele ebalulekile njengamazinga e-pH kanye ne-ORP, zinikeza idatha yesikhathi sangempela ngekhwalithi yamanzi ngqo ngezikrini ezakhelwe ngaphakathi. I-pH iyinkomba ebalulekile yempilo yomhlabathi, ethinta ukutholakala kwezakhamzimba kanye nomsebenzi wamagciwane. I-ORP, ngakolunye uhlangothi, isiza ekunqumeni isimo se-oxidative samanzi, esingathinta impilo yezitshalo kanye nezindawo zemvelo zasemanzini.
Ngokusebenzisa lezi zinzwa, abalimi bangenza izinqumo ezinolwazi mayelana nemikhuba yokunisela, baqinisekise ukuthi izitshalo zabo zithola izimo ezifanele zokukhula.
Umthelela Oguqukayo Emikhubeni Yezolimo
-
Isivuno Esithuthukisiwe:
Ukufinyelela idatha yesikhathi sangempela kuvumela abalimi ukuthi balungise imikhuba yokunisela ngokusekelwe ezidingweni ezithile zezitshalo zabo. Isibonelo, ukuqonda i-pH yenhlabathi kusiza abalimi ukuthi banqume isikhathi esifanele sokusebenzisa umanyolo, okuthuthukisa ukumuncwa kwezakhamzimba, futhi ngenxa yalokho, isivuno sezitshalo. Abalimi ezifundeni ezifana ne-Ica, eyaziwa ngezivini zayo, bazibonela mathupha izinzuzo zokugcina izimo zenhlabathi ezifanele, okuholela ezitshalweni ezinempilo nezikhiqizayo kakhulu. -
Ukulondolozwa Kwamanzi:
Njengoba izindawo eziningi zibhekene nokuntuleka kwamanzi okungapheli, ukunemba okunikezwa izinzwa ze-pH kanye ne-ORP kwenza abalimi bakwazi ukusebenzisa amanzi kahle kakhulu. Ngokusebenzisa amanzi kuphela uma kudingeka futhi ngobuningi obufanele, abalimi bangalondoloza lo mthombo oyigugu ngenkathi besalondoloza izitshalo ezinempilo. Le ndlela ibaluleke kakhulu ezindaweni ezomile zasePeru, lapho ukushoda kwamanzi kusalokhu kuyindaba ekhathazayo. -
Imikhuba Yokulima Eqhubekayo:
Ukuhlanganiswa kwalezi zinzwa kuhambisana nomkhuba okhulayo wezolimo ezisimeme. Ngokunciphisa ukugeleza kwamakhemikhali nokunciphisa ukusetshenziswa ngokweqile komanyolo, abalimi banegalelo empilweni yenhlabathi kanye nokulinganisela kwemvelo. Le ndlela esimeme ibaluleke kakhulu njengoba izimakethe zomhlaba wonke ziqhubeka zifuna imikhuba enobungani nemvelo. -
Izinzuzo Zezomnotho:
Isivuno esithuthukisiwe kanye nokusetshenziswa kwamanzi okuphumelelayo kunegalelo ngqo ekuzinzeni okukhulu komnotho kwabalimi. Ngokukhiqiza okuthuthukisiwe, abalimi abaningi abancane ezifundeni ezifana neCajamarca bangandisa imali engenayo yabo futhi batshale imali kumathuluzi nezindlela ezingcono, kukhuthazwe intuthuko yasemakhaya futhi kuqiniswe ukuqina komphakathi.
Izicelo Zangempela Nezindaba Zempumelelo
Abalimi kulo lonke elasePeru sebevele babika izindaba zempumelelo ezibangelwa ukusetshenziswa kwezinzwa ze-pH kanye ne-ORP. Esifundeni esisogwini saseLa Libertad, abalimi abalima i-asparagus manje sebekwazi ukulungisa imikhuba yabo yokunisela, okuholela ekukhuleni kwesivuno ngo-20%. Ngokufanayo, abakhiqizi be-avocado ezindaweni eziluhlaza zase-Ucayali baphawule ikhwalithi yezithelo ethuthukisiwe kanye nosayizi ngenxa yokunisela okuphathwa kangcono ngokusekelwe kudatha enembile yekhwalithi yamanzi.
Amathemba Esikhathi Esizayo
Ukwamukelwa kwezinzwa ze-pH kanye ne-ORP kuyingxenye eyodwa nje yendlela enkulu yokulima ngokunemba ePeru. Njengoba uhulumeni kanye nomkhakha ozimele beqhubeka nokutshala imali kwezobuchwepheshe bezolimo, abalimi banethemba ngekusasa. Izinhlelo zemfundo nokuqeqeshwa ezithuthukisiwe zizobaluleka ukuqinisekisa ukuthi abakhiqizi bangawasebenzisa ngempumelelo la mathuluzi futhi bamukele imikhuba yesimanje yokulima.
Ekuphetheni, ukuhlanganiswa kwezinzwa zekhwalithi yamanzi ze-pH kanye ne-ORP kuthinta kakhulu ezolimo ePeru, kuqhubekisela phambili ukusungula izinto ezintsha ngenkathi kuxazululwa izinselelo ezibalulekile ekuphathweni kwamanzi, ekukhiqizweni kwezitshalo, kanye nasekuzinzeni. Njengoba abalimi besebenzisa lobu buchwepheshe, amathuba omkhakha wezolimo oqinile aseseduze, ethembisa ikusasa elichumayo emiphakathini yabalimi basePeru futhi eqinisekisa ukuvikeleka kokudla naphezu kwezinselelo zomhlaba wonke.
