Ekukhiqizweni kwezolimo kwanamuhla, ikhwalithi yenhlabathi ithinta ngqo ukukhula kanye nesivuno sezitshalo. Inani lezakhamzimba enhlabathini, njenge-nitrogen (N), i-phosphorus (P) kanye ne-potassium (K), liyisici esibalulekile esithinta impilo yezitshalo kanye nesivuno. Njengethuluzi lezolimo lobuchwepheshe obuphezulu, inzwa ye-NPK yenhlabathi ingaqapha okuqukethwe kwezakhamzimba ze-N, P kanye ne-K enhlabathini ngesikhathi sangempela, isize abalimi ukuthi bavundise ngokunembile futhi bathuthukise ukusebenza kahle kwemikhiqizo yezolimo.
1. Isimiso esiyisisekelo senzwa ye-NPK yenhlabathi
Inzwa ye-NPK yomhlabathi iqapha ukugcwala kwe-nitrogen, i-phosphorus kanye ne-potassium enhlabathini ngesikhathi sangempela ngokusebenzisa ukuhlaziywa kwe-electrochemical noma kwe-spectral. Amanzwa aguqula izilinganiso zibe amasignali kagesi adluliselwa ngaphandle kwentambo efonini noma kwikhompyutha yomsebenzisi, okuvumela abalimi ukuthi bafinyelele isimo sezakhamzimba zenhlabathi nganoma yisiphi isikhathi. Lobu buchwepheshe benza ukuphathwa kwenhlabathi kube ngokwesayensi futhi kusebenze kahle.
2. Imisebenzi eyinhloko yenzwa ye-NPK yenhlabathi
Ukuqapha ngesikhathi sangempela: Kungaqapha izinguquko kokuqukethwe kwe-N, P kanye ne-K enhlabathini ngesikhathi sangempela ukusiza abalimi baqonde isimo sezakhamzimba zenhlabathi ngesikhathi.
Umanyolo oqondile: Ngokusekelwe kudatha yezinzwa, abalimi bangafinyelela umanyolo oqondile, bagweme ukungcola kwemvelo okubangelwa umanyolo owedlulele, futhi baqinisekise ukuthi izitshalo zithola izakhamzimba ezizidingayo.
Ukuhlaziywa kwedatha: Ngemva kokuqoqwa kwedatha, ingahlaziywa ngesofthiwe ukuze kukhiqizwe imibiko enemininingwane yezakhamzimba zomhlabathi ukuze kunikezwe isisekelo sesayensi sezinqumo zezolimo.
Ukuphathwa okuhlakaniphile: Kuhlanganiswe nepulatifomu yamafu, abasebenzisi bangabuka izimo zenhlabathi ngezinhlelo zokusebenza zeselula ukuze bafeze ukuqapha nokuphatha okukude.
3. Izinzuzo zenzwa ye-NPK yenhlabathi
Isivuno esandisiwe: Ngokuvundisa ngokunembile, izitshalo zinikezwa izakhamzimba ezifanele kakhulu, okuholela ekuvuneni nasekhwalithini eyandayo.
Nciphisa izindleko: Ukusetshenziswa komanyolo okunengqondo kunganciphisa ngempumelelo izindleko zokukhiqiza kwezolimo futhi kunciphise umthwalo wezomnotho wabalimi.
Vikela imvelo: Umanyolo oqondile unciphisa ukulahlwa komanyolo, unciphisa ukungcola kwenhlabathi namanzi, futhi unegalelo entuthukweni eqhubekayo.
Kulula futhi kulula ukuyisebenzisa: Izinzwa zesimanje ze-NPK zenzelwe ukuba zisebenziseke kalula futhi zibe lula ukuzisebenzisa, zifanele abakhiqizi bezolimo abanamazinga ahlukene amakhono.
4. Inkambu yesicelo
Izinzwa ze-NPK zenhlabathi zisetshenziswa ezimweni eziningi zokukhiqiza kwezolimo, okuhlanganisa:
Izitshalo zasensimini: njengokolweni, ummbila, ilayisi, njll., ukunikeza abalimi isiqondiso esinembile sokufaka umanyolo.
Izitshalo zezitshalo, njengezithelo nemifino, ziyatshalwa ukuze kuthuthukiswe ikhwalithi yezitshalo ngokuphathwa okuthuthukisiwe kwezakhamzimba.
Ukutshala i-greenhouse: Ezindaweni eziyinkimbinkimbi kakhulu, izinzwa ze-NPK zingasiza ekuqapheni nasekulungiseni izakhamzimba zenhlabathi ukuze kukhule kahle izitshalo.
5. Isifinyezo
Inzwa ye-Soil NPK iyithuluzi elibalulekile kwezolimo zanamuhla, ukusetshenziswa kwayo akugcini nje ngokuthuthukisa isivuno kanye nekhwalithi yezitshalo, kodwa futhi kunciphisa ngempumelelo izindleko zokukhiqiza futhi kuvikele imvelo. Esayensini nasebuchwephesheni obushintsha njalo namuhla, ngosizo lwezinzwa ze-Soil NPK, abalimi bangafinyelela ukuphathwa kwezolimo okungokwesayensi nokuhlakaniphile futhi bakhuthaze intuthuko yezolimo ezisimeme.
Masisebenzise ubuchwepheshe futhi sisebenzise izinzwa ze-NPK zenhlabathi ukuvula isahluko esisha kwezolimo ezihlakaniphile!
