Ungawaqinisa kanjani amanzi okunisela

Kunezitshalo ezithile, ngeshwa, ezingakwazi ukusinda emanzini anamanzi. Futhi yilolo hlobo lwamanzi esinalo ezingxenyeni eziningi zomhlaba, ngokwesibonelo, esifundeni saseMedithera. Amanzi angcono kakhulu kuzo zonke izitshalo yimvula, kodwa-ke, hhayi kuzo zonke izindawo lina imvula eyenele ukukwazi ukuwasebenzisa unyaka wonke, ngakho-ke ... uma singeke sisebenzise amanzi ompompi hhayi amanzi emvula, senzani? 

Impendulo ilula kunendlela ebukeka ngayo, ngoba kufanele nje uyi-asidi. Asibone ungawanciphisa kanjani amanzi okunisela kalula futhi ngokushesha.

Izitshalo ezidinga amanzi okunisela ane-asidi

Kunezinhlobo eziningi ezidinga lolu hlobo lwamanzi. Njengokulandelayo:

• I-Acer palmatum
• IGardenia sp (zonke izinhlobo)
• I-Rhododendron sp (zonke izinhlobo)
• I-Pieris sp (zonke izinhlobo)
• I-Lagerstroemia sp (zonke izinhlobo)
• IHydrangea sp (zonke izinhlobo)
• I-Liquidambar sp (zonke izinhlobo)

Uma kwenzeka ungabaza, kuzokwanela qaphela amaqabunga yesitshalo. Uma ziqala ukubukeka njenge-chlorotic, okungukuthi, ezinemizwa emakwe kakhulu, eluhlaza ngombala, kepha lonke elinye iqabunga libukeka liphuzi, kungenxa yokuthi lidinga insimbi ngokuphuthumayo - imvamisa iyona evame kakhulu - noma i-magnesium.

Ukuvikela inkinga ukuthi ingakhuli, kuyalulekwa sebenzisa ama-substrates ane-pH ephansi (phakathi kuka-4 no-6, ubuningi be-6,5), fakela umanyolo wezitshalo ze-acidophilic entwasahlobo nasehlobo, futhi wenze ne-acidify amanzi okunisela.

Ungawaqinisa kanjani amanzi okunisela kalula?

Uma sinezitshalo ezidinga amanzi ane-asidi, akudingekile ukuthi kube nzima kakhulu ukukunika. Empeleni, kuzokwanela ukuzama noma iyiphi yalezi zindlela ezintathu:

1. Enye yazo iqukethe engeza uketshezi lwengxenye yelamula kulitha elilodwa lamanzi, ugovuze kahle ukuxuba.
2. Owesibili uqukethe engeza isipuni seviniga kwilitha elilodwa lamanzi, ugovuze.
3. Owesithathu uqukethe gcwalisa ibhakede noma umcengezi ngamanzi, mawume ubusuku bonke, bese ngakusasa usebenzise amanzi avela engxenyeni engenhlanjengoba ingeke ibe nezinsimbi eziningi ezisindayo. Vele, leli qhinga lizosebenza kuphela uma amanzi ompompi engenayo i-pH ephezulu kakhulu, kepha angaphezu kuka-7. Uma ungazi ukuthi i-pH amanzi anani, ungathola imichilo ye-pH (iyathengiswa lapha) noma a imitha yedijithali (ongakuthola kuyathengiswa lapha).

Yimaphi ama-acid asetshenziswa kakhulu kwezolimo ukwehlisa i-pH yamanzi?

Kukhona ama-acid akhonza ukuthuthukisa ikhwalithi yamanzi. Lapha sizofunda ukuthi singenisa kanjani amanzi okunisela kwezolimo. Ukwengezwa kwama-asidi emanzini kunenhloso enkulu yokulungisa i-pH yamanzi nokukwazi ukuyinciphisa. Iphinde isebenze ukuhlinzeka inani elikhulu lezakhamzimba ezitshalweni. Kulesi sigxivizo akukho monakalo ezitshalweni futhi isixazululo sehliselwa ku-pH ka-5.5 kuye ku-6.5, okungukuthi, i-acidic kancane.

Ama-acids ajwayelekile asetshenziselwa ukufunda ukuthi angenziwa kanjani amanzi okunisela ngenkasa yi-nitric, i-phosphoric, ne-sulfuric.. Lesi sakamuva sisetshenziswa kabanzi ngokuba ukonga kakhulu, yize ezimbili ezedlule zisetshenziswa kulimo lwezitshalo oluvikelwe ngoba zinomsebenzi wokunikeza izakhamzimba nokwenza i-asidi enhlabathini. Ukukhetha i-asidi ezosetshenziswa, kufanele kubhekwe lezi zici ezilandelayo: okokuqala, ukuthi iyi-asidi ekulula ukuyisebenzisa. Okwesibili ukuthi kuphephile futhi okwesithathu ukuthi kunezindleko eziphansi kunalokho engingakunikeza izakhi zomsoco ezanele ezitshalweni.

Ukwenza ngcono ikhwalithi yamanzi zivame ukusetshenziswa njengezinto ezingavuthiwe zokukhiqiza umanyolo we-nitrogen, yize kusebenza futhi ukwehlisa i-pH yamanzi. Emakethe ye-agrochemical singathola ubumsulwa obuhlukahlukene be-asidi nokugxila. I-Industrial grade acid ijwayele ukusetshenziselwa ukusetshenziswa kwezolimo, kanti ibanga le-reagent lisetshenziselwa ukusetshenziswa kwelabhorethri.

Izinkinga zamanzi eziphakeme kakhulu

Siyazi ukuthi izinga lamanzi okusetshenziswa kwezolimo lingesinye sezici ezibaluleke kakhulu nokuthi lithinta ukukhula nokuthuthuka kwemifino. Njengamanje, iningi lamanzi asetshenziswa kulo mkhakha kumele linikezwe kuqala ukuze kuvinjelwe izinkinga ezingase zivele enhlabathini noma engxenyeni engaphansi komhlaba. Amanzi amaningi asetshenziswa kwezolimo asetshenziselwa ukunisela nokufaka umanyolo. Izinkinga eziqondile ezihlobene nekhwalithi yamanzi zivame ukulandela lokhu: usawoti, isodiyamu, i-alkalinity kanye nobuthi ngama-ion athile.

Yonke le mikhawulo emanzini ingalinganiswa ngamapharamitha athile ahlobene nekhwalithi yamanzi. Le mingcele elandelayo kuphela: ukuqhutshwa kukagesi, i-pH, ukugxila kwezinto ezingaba nobuthi kanye ne-sodium adsorption ratio. Ama-Carbonates nama-bicarbonate ngosawoti abakhona emanzini futhi uma inani lenyuka, i-pH nayo ingakhuphuka. Kumele kuqashelwe ukuthi i-alkalinity ne amanzi pH ziyizici ezimbili ezihlobene kodwa azifani. Ukudideka phakathi kwe-pH ephezulu kanye ne-alkalinity ephezulu ikakhulukazi kungenxa yokuthi amanzi abizwa njengamanzi ane-alkaline inqobo nje uma ene-pH ephakeme kune-7. Kubizwa nangokuthi ukuba ne-alkalinity ephezulu uma kunokuhlushwa okuphezulu kwezisekelo.

Kukhona ezinye izingozi lapho usebenzisa amanzi ane-alkaline kakhulu ezinhlelweni zokunisela ngaphandle kokwelashwa kwangaphambili. Kukhona ubungozi bokuvaleka kwabadonsa phansi ngoba ama-bicarbonate bicarbonates anciphisa ama-cations akhona emanzini futhi enza izinhlanganisela zokuncibilika okuncane njenge-calcium carbonate, i-calcium bicarbonate, i-sodium ne-magnesium. Yini enye, i-pH ephezulu kakhulu emanzini ithinta ukutholakala kwezakhamzimba ezidingwa isitshalo njenge-zinc, i-iron ne-manganese.

Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nokuthi ungawaqinisa kanjani amanzi nokuthi wenzani ukuze unisele izitshalo zakho ngamanzi okunisela adinga wona.
