Ungayenza njani i-asidi yokunkcenkceshela amanzi

Kukho izityalo ezithile, ngelishwa, ezingenakuphila kumanzi alinganayo. Kwaye luhlobo lwamanzi esinalo kwiindawo ezininzi zehlabathi, umzekelo, kwingingqi yeMeditera. Awona manzi alungileyo kuzo zonke izityalo ngamanzi emvula, kodwa ke, ayizizo zonke iindawo ezinetha ngokwaneleyo ukuze zikwazi ukuwasebenzisa unyaka wonke, ke ... ukuba asinakho ukusebenzisa amanzi etephu hayi amanzi emvula, senza ntoni? 

Impendulo ilula kunokuba ibonakala, kuba kuya kufuneka uyi-asidi. Masibone ukuwanciphisa njani amanzi okunkcenkceshela ngokulula nangokukhawuleza.

Izityalo ezifuna amanzi okunkcenkceshela ane asidi

Zininzi iintlobo ezifuna olu hlobo lwamanzi. Ezi zilandelayo:

• Acer palmatum
• Igadiya sp (Zonke iintlobo)
• Rhododendron sp. (Zonke iintlobo)
• I-Pieris sp (zonke iintlobo)
• ILagerstroemia sp (Zonke iintlobo)
• IHydrangea sp (Zonke iintlobo)
• liquidambar sp. (Zonke iintlobo)

Kwimeko yokuthandabuza, kuya kwanela jonga amagqabi yesityalo. Ukuba baqala ukujonga iklorotic, oko kukuthi, ngemithambo ephawulwe kakhulu, luhlaza ngombala, kodwa onke amanye amagqabi akhangeleka etyheli, kungenxa yokuba ifuna intsimbi ngokungxama-ihlala iyinto exhaphakileyo- okanye i-magnesium.

Ukuthintela ingxaki ekubeni inyuke, kuyacetyiswa Sebenzisa ii-substrates ezine-pH esezantsi (phakathi kwe-4 kunye ne-6, ubuninzi be-6,5), chumisa ngezichumisi zezityalo ze-acidophilic entwasahlobo nasehlotyeni, kunye ne-acidify amanzi okunkcenkceshela.

Ungawanciphisa njani amanzi okunkcenkceshela ngokulula?

Ukuba sinezityalo ezifuna amanzi aneasidi, akuyomfuneko ukuba kube nzima ukukunika. Ngokwenyani kuya kwanela ukuzama naliphi na kula maqhinga mathathu:

1. Enye yazo iquka yongeza ulwelo lwesiqingatha selamula kwilitha enye yamanzi, kwaye uvuselele kakuhle ukuxuba.
2. Eyesibini iquka yongeza icephe leviniga kwilitha enye yamanzi, kwaye uvuse.
3. Inxalenye yesithathu ine gcwalisa i-emele okanye isitya ngamanzi, masihlale ubusuku bonke, kwaye ngosuku olulandelayo usebenzise amanzi asuka kwisiqingatha esingaphezulunjengoko ayinakuba nezinyithi ezininzi ezinzima. Ewe, eli qhinga liza kusebenza kuphela xa amanzi etephu engenayo i-pH ephezulu kakhulu, kodwa ngaphezulu kwe-7. aphaokanye a imitha yedijithali (onokuyifumana iyathengiswa apha).

Zeziphi iiasidi ezisetyenziswa kakhulu kwezolimo ukuthoba i-pH yamanzi?

Kukho ezinye iiasidi ezisebenza ukuphucula umgangatho wamanzi. Apha siza kufunda ngendlela yokwenza i-asidi yokunkcenkceshela amanzi kwezolimo. Ukongezwa kweeasidi emanzini kunenjongo ephambili yokulungisa i-pH yamanzi kunye nokukwazi ukuyithomalalisa. Kuyanceda ukubonelela ngesixa esikhulu sezondlo kwizityalo. Kule nkxalabo akukho monakalo kwizityalo kwaye isisombululo sehliswa kwi-pH ye-5.5 ukuya kwi-6.5, okt i-asidi encinci.

Iiasidi eziqhelekileyo ezisetyenziselwa ukufunda indlela yokwenza i-asidi yokunkcenkceshela amanzi zii-nitric, i-phosphoric kunye ne-sulfuric.. Le yokugqibela isetyenziswa ngokubanzi ukuba ibe yeyoqoqosho kakhulu, nangona ezi zimbini zangaphambili zisetyenziswa kulimo olukhuselweyo lokulima kuba zinomsebenzi wokubonelela ngezakhamzimba kunye nokwenza umhlaba ube ngumhlaba. Ukukhetha iasidi oza kuyisebenzisa, ezi mpawu zilandelayo kufuneka zithathelwe ingqalelo: Okokuqala, kukuba kulula ukuyisebenzisa i-asidi. Okwesibini kukuba kukhuselekile kwaye okwesithathu inexabiso eliphantsi kunokuba ndinokubonelela ngezondlo ezaneleyo kwizityalo.

Ukuphucula umgangatho wamanzi zihlala zisetyenziswa njengempahla eluhlaza kwimveliso yezichumisi ze-nitrogen, nangona ikwanceda ukuthoba i-pH yamanzi. Kwimarike ye-agrochemical sinokufumana ucoceko olwahlukileyo lweasidi kunye nokugxila. Ngokwesiqhelo ukusetyenziswa kwezolimo kwinqanaba le-acid lisetyenziswa, ngelixa ibakala lereagent lisetyenziselwa elebhu.

Iingxaki eziphezulu zamanzi

Siyazi ukuba umgangatho wamanzi osetyenziselwa ezolimo yenye yezona zinto zibaluleke kakhulu kwaye uchaphazela ukukhula nokukhula kwemifuno. Okwangoku, uninzi lwamanzi asetyenzisiweyo kwicandelo kufuneka anikwe kuqala ukuthintela iingxaki ezinokubakho emhlabeni okanye kumhlaba ongaphantsi. Uninzi lwamanzi asetyenziswa kwezolimo asetyenziselwa ukunkcenkceshela kunye nokuchumisa. Iingxaki ezichanekileyo ezinxulumene nomgangatho wamanzi zihlala zilandelayo: ityuwa, isodiyam, ialkalinity kunye netyhefu yiion ezithile.

Zonke ezi zithintelo emanzini zinokulinganiswa ngeeparameter ezithile ezinxulumene nomgangatho wamanzi. Ezi kuphela zeeparameter zilandelayo: Ukuqhutywa kombane, i-pH, uxinzelelo lwezinto ezinokuba yityhefu kunye nomyinge we-adsorption we-sodium. Iicarbonates kunye ne-bicarbonates zityiwa ezikhoyo emanzini kwaye ukuba uxinzelelo lwandisiwe, i-pH nayo ingonyuka. Kufuneka kuqatshelwe ukuba i-alkalinity kunye pH yamanzi zizinto ezimbini ezinxulumene nenye kodwa azifani. Ukudideka phakathi kwe-pH ephezulu kunye ne-alkalinity ephezulu ikakhulu kungenxa yokuba amanzi abizwa njengamanzi e-alkaline okoko nje ene-pH ephezulu kune-7.. Ikwabizwa ngokuba ne-alkalinity ephezulu ukuba ine-concentration ephezulu yeziseko.

Kukho imingcipheko xa usebenzisa amanzi anealkali kakhulu kwiinkqubo zokunkcenkceshela ngaphandle konyango lwangaphambili. Kukho umngcipheko wokuvaleka kweedropha kuba ii-bicarbonate bicarbonates zithintela ii-cations ezikhoyo emanzini kwaye zenza iikhompawundi zokunyibilika eziphantsi njenge calcium carbonate, calcium bicarbonate, isodiyam kunye nemagniziyam. Yintoni egqithisile, ipH ephezulu kakhulu emanzini ichaphazela ubukho bezinongo ezifunwa sisityalo ezifana ne-zinc, i-iron kunye ne-manganese.

Ndiyathemba ukuba ngolu lwazi ungafunda ngakumbi malunga nokwenza i-asidi amanzi kunye nento eyenzayo ukuze unkcenkceshele izityalo zakho ngamanzi enkcenkceshelo awadingayo.
