Isifinyezo: Kumagagasi oshintsho ukusuka kwendabuko ukuya kokunemba kanye nezolimo ezihlakaniphile, izinzwa ze-pH yekhwalithi yamanzi ziyashintsha zisuka kumathuluzi angajwayelekile aselabhorethri ziye “kumilando ohlakaniphile” wenkundla. Ngokuqapha i-pH yamanzi okunisela ngesikhathi sangempela, avikela ukukhula kwezitshalo futhi abe yingxenye eyinhloko ekulawulweni kwamanzi kwesayensi nomanyolo.
I. Isendlalelo: Isimo esibucayi se-“Tomato Valley”
“Esikhungweni semibukiso sesimanje sezolimo esiseMpumalanga ye-China, bekunendlu yokushisa yengilazi yesimanje engamahektha angu-500 enikezelwe ekukhuliseni utamatisi we-cherry wekhwalithi ephezulu, owaziwa ngokuthi “Isigodi Sotamatisi.” Umphathi wepulazi, uMnu. Wang, wayehlale ekhathazwa inkinga: ukukhula kwezitshalo ngokungalingani, nokuphuzi kwamaqabunga kanye nokukhula okukhubazekile kwezinye izindawo, kuhambisana nokusebenza kahle kukamanyolo.
Ngemuva kophenyo lokuqala, izinambuzane, izifo, nokushoda kwezakhi zomsoco kwakhishwa. Ukugxila ekugcineni kushintshele emanzini okunisela. Umthombo wamanzi uvela emfuleni oseduze futhi waqoqa amanzi emvula, futhi inani lawo le-pH lashintshashintsha ngenxa yesimo sezulu kanye nezinguquko zemvelo. Basola ukuthi i-pH yamanzi engazinzile iphazamisa ukutholakala kukamanyolo, okuholela ezinkingeni ezibonwayo.
II. Isixazululo: Ukusebenzisa Uhlelo Lokuqapha Lwe-pH Oluhlakaniphile
Ukuze kuxazululwe le nkinga ngokuqinisekile, isisekelo "soMthombo Oluhlaza" sethule futhi sasebenzisa uhlelo lokuqapha amanzi okunisela oluhlakaniphile olusekelwe kuzinzwa ze-pH zekhwalithi yamanzi eziku-inthanethi.
- Ukwakhiwa Kwesistimu:
- Izinzwa ze-pH eziku-inthanethi: Ifakwe ngqo epayipini elikhulu lokunisela lamanzi okunisela kanye nalapho kuphuma khona ithange lokuxuba umanyolo ku-greenhouse ngayinye. Lezi zinzwa zisebenza ngomgomo wendlela ye-electrode, okuvumela ukutholwa okuqhubekayo, ngesikhathi sangempela se-pH yamanzi.
- Imojula Yokutholwa Kwedatha Nokudlulisa: Iguqula amasignali e-analog asuka kuzinzwa abe amasignali edijithali futhi iwathumele ngokungenantambo kuplathifomu yokulawula emaphakathi ngobuchwepheshe be-inthanethi Yezinto (IoT).
- I-Smart Central Control Platform: Isistimu yesofthiwe esekelwe emafini enesibopho sokwamukela, ukugcina, ukubonisa, nokuhlaziya idatha ye-pH, kanye nokusetha imingcele yokuphatha.
- I-Automatic Adjustment System (Ongakukhetha): Ixhunywe kuplathifomu, ilawula ngokuzenzakalela ukujova amanani amancane e-asidi (isb, i-phosphoric acid) noma isixazululo se-alkali (isb., i-potassium hydroxide) ukuze kulungiswe kahle i-pH uma amanani ephuma ebangeni.
- Ukuhamba komsebenzi:
- Ukuqapha Kwesikhathi Sangempela: I-pH yamanzi okunisela ithathwa ngesikhathi sangempela yizinzwa ngaphambi kokuba ingene ohlelweni lokunisela lokunisela.
- Ama-Threshold Alarms: Ibanga le-pH elilungile lokukhula kukatamatisi we-cherry (5.5-6.5) libekwe endaweni yokulawula emaphakathi. Uma i-pH yehla ngaphansi kuka-5.5 noma ikhuphuka ngaphezu kuka-6.5, isistimu ithumela ngokushesha isaziso kubaphathi ngohlelo lokusebenza lweselula noma ikhompuyutha.
- Ukuhlaziywa Kwedatha: Inkundla ikhiqiza amashadi ethrendi ye-pH, isiza abaphathi ukuthi bahlaziye amaphethini nezimbangela zokuguquguquka kwe-pH.
- Ukulungiswa Okuzenzakalelayo/Ngesandla: Isistimu ingasethwa kumodi ezenzakalelayo ngokugcwele, yengeze i-asidi noma i-alkali ukuze ilungise kahle i-pH enani eliqondiwe (isb, 6.0). Okunye, abaphathi bangakwazi ukwenza kusebenze isistimu yokulungisa bekude lapho bethola isexwayiso.
III. Imiphumela yohlelo lokusebenza kanye nenani
Ngemuva kwezinyanga ezintathu zokusebenzisa uhlelo, isisekelo "soMthombo Oluhlaza" sizuze izinzuzo ezibalulekile zezomnotho nezemvelo:
- Ukusebenza Okuthuthukisiwe Komanyolo, Izindleko Ezincishisiwe:
- Izakhi eziningi (njenge-nitrogen, i-phosphorus, i-potassium) zitholakala kalula ezitshalweni endaweni ene-acidic kancane (pH 5.5-6.5). Ngokulawula kahle i-pH, ukusebenza kahle komanyolo kukhuphuke cishe ngo-15%, kunciphisa ukusetshenziswa kukamanyolo cishe ngo-10% kuyilapho kugcinwa isivuno.
- Impilo Yezitshalo Ethuthukisiwe, Ikhwalithi Ethuthukisiwe kanye Nesivuno:
- Izinkinga ezixazululiwe ezifana “ne-chlorosis yokuntuleka komsoco” (amaqabunga aphuzi), ezenzeke ngenxa yokuthi i-pH ephezulu ivalele ama-micronutrients afana ne-iron ne-manganese, okwenza ukuthi angatholakali ezitshalweni. Ukukhula kwezitshalo kwaba yinto efanayo, futhi amaqabunga aphenduka abe luhlaza okunempilo.
- Izinga le-Brix, ukunambitheka, kanye nokuvumelana kwamatamatisi we-cherry kube ngcono kakhulu. Izinga lezithelo ezidayiswayo lenyuke ngo-8%, likhuphule ngqo inzuzo yezomnotho.
- Ukuphatha Ukunemba Okunikwe amandla, Umsebenzi Olondoloziwe:
- Kushintshwe indlela ephelelwe yisikhathi yokudinga amasampula okwenziwa njalo nokuhlola ngemichilo yokuhlola i-pH noma amamitha aphathekayo. Kunikwe amandla ukuqapha okunganakiwe okungu-24/7, kusindisa kakhulu abasebenzi futhi kuqedwe iphutha lomuntu.
- Abaphathi bangabheka izinga lezinga lamanzi lalo lonke uhlelo lokunisela noma nini, noma kuphi besebenzisa amafoni abo, okwenza ngcono kakhulu ukuphatha kahle.
- Ukuvinjelwa Kwesistimu, Izindleko Ezincishisiwe Zokulungisa:
- I-pH ephezulu kakhulu ingabangela i-calcium ne-magnesium ions emanzini ukuthi ihle, yenze isikali esivala ama-drip emitters athambile. Ukugcina i-pH efanele kwehlisa ukwakheka kwesikali, kwandise isikhathi sokuphila sohlelo lokunisela ngamaconsi, kanye nokunciphisa imvamisa yokulungisa kanye nezindleko.
IV. Ikusasa Outlook
Ukusetshenziswa kwezinzwa ze-pH zamanzi kudlulela ngale kwalokhu. Ohlelweni lwezolimo oluhlakaniphile lwesikhathi esizayo, luzodlala indima ebaluleke kakhulu:
- Ukuhlanganiswa Okujulile Nezinhlelo Zokuvundisa: Izinzwa ze-pH zizohlangana nezinzwa ze-EC (Electrical Conductivity) kanye nama-electrode ahlukahlukene e-ion-selective (isb, i-nitrate, i-potassium) ukuze akhe “uhlelo lokuxilongwa okunomsoco” oluphelele lokuvundiswa okudingekayo kanye nokunisela ngokunemba.
- Ukulawula Ukuqagela Okunamandla e-AI: Ngokuhlaziya idatha yomlando ye-pH, idatha yesimo sezulu, namamodeli okukhula kwezitshalo ngama-algorithms e-AI, uhlelo lungabikezela amathrendi e-pH futhi lungenelele ngokuqhubekayo, lusuka “ekulawuleni kwesikhathi sangempela” luye “ekulawuleni okubikezelwayo.”
- Ukunwetshwa kwe-Aquaculture kanye Nokuqapha Umhlabathi: Ubuchwepheshe obufanayo bungasetshenziswa ekulawuleni izinga lamanzi emachibini e-aquaculture futhi busetshenziswe njenge-probe yokuqapha i-pH yenhlabathi e-in-situ, ukwakha inethiwekhi yokuqapha imvelo yezolimo ephelele.
Isiphetho:
Indaba yesisekelo esithi "Umthombo Oluhlaza" ikhombisa ngokusobala ukuthi inzwa ye-pH yamanzi ethobekile iyibhuloho elixhumanisa ukuphathwa kwemithombo yamanzi kanye nempilo yezitshalo ezinomsoco. Ngokuhlinzeka ngedatha eqhubekayo, enembile, iphusha “ezolimo ezisekelwe ekuhlangenwe nakho” kwendabuko “kwezolimo eziqhutshwa yidatha ehlakaniphile,” enikeza ukusekelwa okuqinile kobuchwepheshe ukuze kuzuzwe ukongiwa kwamanzi, ukuncishiswa kukamanyolo, ukuthuthukiswa kwekhwalithi, ukuthuthukiswa kokusebenza kahle, kanye nentuthuko yezolimo esimeme.
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
Ukuze uthole inzwa yamanzi eyengeziwe ulwazi,
