Kwezolimo zanamuhla, ukuphatha okunembayo kanye nentuthuko esimeme sekuyizinto eziseqhulwini kososayensi bezolimo. Ukuqapha izinga lamanzi kuyingxenye ebalulekile yale nqubo, ikakhulukazi mayelana ne-soluble carbon dioxide (CO₂). E-United States, izinzwa zekhwalithi yamanzi ze-CO₂ zisetshenziswa kakhulu emikhakheni efana nokulinywa kwe-greenhouse, i-aquaculture, nezinhlelo zokunisela. Ngezansi kunecala elithile elibonisa ukusetshenziswa okungokoqobo kwezinzwa zekhwalithi yamanzi CO₂ kwezolimo zaseMelika.
Ingemuva
I-greenhouse enkulu etholakala e-California igxile ekutshaleni imifino nezimbali zenani eliphezulu futhi ibhekane nezinselelo mayelana nokuphathwa kwekhwalithi yamanzi nokukhula kwezitshalo. Ngokuthuthuka kwezobuchwepheshe bezolimo, i-greenhouse isebenzise izinzwa zekhwalithi yamanzi ze-CO₂ ukuze kuthuthukiswe izimo ezikhulayo zezitshalo futhi kuthuthukiswe kokubili isivuno nekhwalithi.
Izicelo Ezisebenzayo
Ukuqapha Ikhwalithi Yamanzi
I-greenhouse isebenzisa izinzwa zekhwalithi zamanzi ze-CO₂ ukuze ihlale iqapha ukugxila kwe-carbon dioxide emanzini okunisela ngesikhathi sokunisela nokuvundiswa. Ngokulandelela amazinga e-CO₂ emanzini, ipulazi lingaqonda kangcono izinguquko ku-acidity yamanzi (pH) kanye nemiphumela yazo ekukhuleni kwezitshalo.
I-Smart Irrigation System
Lapho izinzwa zithola ukwenyuka kokuhlushwa kwe-CO₂ emanzini, uhlelo lulungisa ngokuzenzakalelayo uhlelo lokunisela. Lokhu kulungiswa okuzenzakalelayo kuthuthukisa ukuhlinzekwa kwamanzi nezakhamzimba, kuqinisekisa ukuthi izitshalo zikhula ngaphansi kwezimo ezifanele. Isibonelo, lapho ukugxila kwe-CO₂ kuphansi, uhlelo lunyusa amazinga e-CO₂ ukuze kuthuthukiswe i-photosynthesis, ngaleyo ndlela kuthuthukise amazinga okukhula kwezitshalo.
I-Crop Yield Prediction
Ngokuhlaziya idatha yomlando kanye nedatha yekhwalithi yamanzi yesikhathi sangempela, abaphathi be-greenhouse bangabikezela amathrendi okukhula kanye nesivuno esingaba khona ezitshalweni zabo. Idatha ehlinzekwa yizinzwa zekhwalithi yamanzi CO₂ isekela ukwakhiwa kwezinqumo ezinembile zokuphatha ezolimo, njengokuhlela okufika ngesikhathi nokufanelekile kokuvundisa nokunisela.
Imiphumela kanye Nempendulo
Ngemuva kokusebenzisa ukuqapha kwekhwalithi yamanzi CO₂, i-greenhouse yabhekana nokwanda okukhulu kokukhiqiza. Ngonyaka wokuqala wokwethula izinzwa, isivuno sikhuphuke cishe ngamaphesenti angama-20, futhi ikhwalithi yezitshalo nayo yaba ngcono ngokuphawulekayo. Abaphathi babike ukuthi ukuqapha ngesikhathi sangempela kanye nokulungiswa kwezimo zokunisela kubavumele ukuthi baphendule ngokushesha ezindabeni zokukhula, ukunciphisa ukumosha nokuthuthukisa ukusebenza kahle kwemithombo yamanzi.
Amathemba Ekusasa
Njengoba ubuchwepheshe bezolimo buqhubeka nokuthuthuka, ukusetshenziswa kwezinzwa zekhwalithi yamanzi ze-CO₂ kuzonwebeka ezindaweni zezolimo ezengeziwe, okuhlanganisa ukufuywa kwezilwane zasemanzini, ukuqapha umhlabathi, nezinye izindawo zokulima izitshalo. Ngokuhlanganisa ubuhlakani bokwenziwa kanye nokuhlaziywa kwedatha enkulu, ikusasa lezolimo lithembisa ukusebenza kahle kakhulu nokusimama, lisize uguquko emkhiqizweni wezolimo.
Isiphetho
Ngokusebenzisa izinzwa zekhwalithi yamanzi ze-CO₂ ku-greenhouse yase-California, sibona indlela ezolimo zesimanje ezisebenzisa ngayo ubuchwepheshe ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza kanye nekhwalithi yezitshalo. Lokhu akuvezi nje kuphela izinzuzo ezingokoqobo zokukhiqiza ezolimo kodwa futhi kunikeza imininingwane ebalulekile yokuthuthukisa intuthuko yezolimo esimeme. Njengoba ubuchwepheshe buqhubeka buthuthuka, ukuqapha izinga lamanzi sekukulungele ukuba ithuluzi elibalulekile ekuphathweni kwezolimo esikhathini esizayo.
Futhi singahlinzeka ngezixazululo ezahlukahlukene
1. Imitha ephathwa ngesandla yekhwalithi yamanzi enepharamitha eningi
2. Isistimu ye-Buoy entantayo yekhwalithi yamanzi enepharamitha eminingi
3. Ibhulashi lokuhlanza okuzenzakalelayo lenzwa yamanzi yepharamitha eminingi
4. Isethi ephelele yamaseva nesoftware engenantambo, isekela i-RS485 GPRS /4g/WIFI/LORA/LORAWAN
