Kutheni i-TDS yamanzi empompo ingama-400 PPM phambi kokongeza izondlo — nendlela yokuyilungisa
Ufundo lwama-400 PPM emanzini empompo lusuka kwiiminerali zikamasipala ezinyibilikileyo ezinjengekhalsiyam, imagnesiyam neekhabhoneyithi. Nantsi indlela yokulungelelanisa umlinganiselo wezondlo we-hydroponics yeklasi yakho ngaphandle kokuthenga ifiltha ye-reverse osmosis.
Ufundo lwamanzi empompo lwama-400 PPM (iinxalenye ngesigidi) luthetha ukuba imbonelelo kamasipala wakho sele ithwele umthwalo onzima weeminerali ezinyibilikileyo—ikakhulu ikhalsiyam, imagnesiyam, iibhayikhabhoneyithi, iisalfeyithi nesodiyam. Imitha yakho ye-Total Dissolved Solids (TDS) ayikwazi ukwahlula phakathi kwenayitrojini enokufikelelwa sisityalo nekalika yamanzi empompo; ilinganisa nje ukuqhutywa kombane (i-EC) ize ikuguqule kube bubunzima obuqikelelweyo.
Ukuba ulandela ngokungaqiqiyo iitshathi eziqhelekileyo zokondla ezenzelwe amanzi acocekileyo, olu fundo luphezulu lomgangatho osisiseko luya kubangela nokuba zizithole ezingondlekanga, ezitshintsha zibe tyheli, okanye ubuthi obumandundu betyuwa. Awuyifuni inkqubo ye-reverse osmosis (RO) yamawaka eerandi ukuze usombulule le nto kwimeko yesikolo. Into oyifunayo kukulungelelanisa izibalo zakho kunye nolandelelwano lwakho lokuxuba.
Yintoni ngokwenene elinganiswa ngama-400 PPM
Iisiba ze-TDS azibali iinxalenye ezincinane. Zilinganisa ukuhamba komsinga wombane phakathi kwee-electrode ezimbini (nge-microSiemens ngesentimitha, okanye µS/cm) zize ziphinde-phinde elo nani ngesiphindi sokuguqula—ngokuqhelekileyo u-0.5 (isikali se-500/NaCl) okanye u-0.7 (isikali se-442/Truncheon). Ufundo lwama-400 PPM kwisikali esiqhelekileyo se-0.5 lumela i-EC esisiseko ye-0.8 mS/cm.
Kwiindawo ezininzi zoMzantsi Afrika—ingakumbi iindawo ezingaphakathi elizweni ezikha kwii-aquifer zedolomite, okanye iinethiwekhi zaselunxwemeni ezixuba amanzi eqhuqhuva ngamaxesha omileyo—loo 0.8 EC yenziwe zezi:
- Iikhabhoneyithi zekhalsiyam nezemagnesiyam: Ezona zinto zibangela ubulukhuni beeminerali kunye ne-pH esisiseko ephezulu (rhoqo phakathi ko-7.8 no-8.4).
- Isodiyam neekloraydi: Iityuwa eziseleyo ezivela ekucocweni kwamanzi nakwimaleko zomhlaba, izityalo ezizisebenzisa ngobuncinane obungathi asiboni.
- Iibhayikhabhoneyithi: Iikhompawundi zendalo ezizinzisayo ezinciphisa i-asidi zize zichase iinzame zakho zokuthoba i-pH yetanki.
Imigibe emibini yegumbi lokufundela
Xa ootitshala bedibana namanzi empompo ama-400 PPM, badla ngokwenza enye yeempazamo ezimbini xa belandela iresiphi eqhelekileyo ye-hydroponics (njengekhwelo lama-800 PPM kwimifuno enamagqabi):
1. Umgibe wokuncipha kwamandla (ukungondli ngokwaneleyo)
Utitshala wongeza isondlo esiqinileyo de imitha ibonise ama-800 PPM. Kuba amanzi empompo sele efake ama-400 PPM, ufake kuphela isichumiso esilinganiselweyo esixabisa ama-400 PPM. Isiqingatha sezinto eziqinileyo ezinyibilikileyo etankini ziiminerali zempompo ezingacocwanga, endaweni yenayitrojini, ipotasiyam nefosforasi ezifunwa zizityalo. Isiphumo: ukukhula okucothayo, amagqabi angqungqulu, kunye nokukhula okubuthathaka kweengcambu.
2. Umgibe wophahla (ukutsha ngetyuwa)
Utitshala wongeza umlinganiselo opheleleyo ocetyiswayo (masithi, i-+800 PPM yezondlo) ngqo phezu komgangatho osisiseko wama-400 PPM, atyhale isixa sisonke siye kuma-1,200 PPM. Nangona izityalo ezikhulileyo ezithelayo ezinjengeetumato zinokumelana nokuqhutywa kombane okuphezulu, iletusi encinci okanye imifuno enevumba emagumbini okufundela afudumeleyo iya kubandezeleka kuxinzelelo lwe-osmosis. Iingcambu zisokola ukukha amanzi zichasene noxinzelelo lwe-osmosis oluphezulu olungaphandle, nto leyo ibangela ukutsha kweencam nokubuna ebudeni beeyure ezishushu kakhulu zemini.
Indlela yokugalela izondlo emanzini ama-400 PPM ngaphandle kwe-reverse osmosis
Ukucoca ngokwe-reverse osmosis akufane kusebenze ezikolweni. Iiyunithi ze-RO zasekhaya zichitha iilitha ezintathu ukuya kwezine zamanzi kwilitha nganye ecociweyo, zifuna uxinzelelo olungapheliyo lwamanzi omgca ophambili, kwaye zifuna ukutshintshwa kweefiltha rhoqo into engafane ihlawulelwe luhlahlo-lwabiwo-mali lokusebenza lwesikolo. Endaweni yoko, lawula amanzi akho omthombo ane-TDS ephezulu usebenzisa le nkqubo yamanyathelo amahlanu.
Inyathelo 1: Suka kwi-TDS ekujoliswe kuyo uye kwi-"EC eyongeziweyo"
Yeka ukulinganisa i-TDS iyonke ngokwezinto ezijoliswe kuzo kwiitshathi eziqhelekileyo. Endaweni yoko, thatha amanzi akho empompo njengomgangatho osisiseko ongenanto kwizondlo ezinkulu, kodwa ulinganise i-delta (i-EC eyongeziweyo):
| Uhlobo lwesityalo | I-EC esisiseko yasempompo | I-EC yezondlo omawuyongeze | I-EC epheleleyo ekujoliswe kuyo |
|---|---|---|---|
| Izithole / I-microgreens | 0.8 mS/cm (400 PPM) | + 0.4 mS/cm (200 PPM) | 1.2 mS/cm (600 PPM) |
| Imifuno enamagqabi / Imifuno enevumba | 0.8 mS/cm (400 PPM) | + 0.8 mS/cm (400 PPM) | 1.6 mS/cm (800 PPM) |
| Izityalo ezithelayo (inqanaba lokuthela) | 0.8 mS/cm (400 PPM) | + 1.4 mS/cm (700 PPM) | 2.2 mS/cm (1,100 PPM) |
Inyathelo 2: Thoba i-alkhalinithi phambi kokongeza izondlo
Amanzi kamasipala ane-TDS ephezulu ngokuqhelekileyo anesixa esiphezulu seebhayikhabhoneyithi, esitsala i-pH iye ngaphezu ko-8.0. Ukuba wongeza izondlo eziqinileyo ngqo emanzini alukhuni ane-pH ephezulu, ikhalsiyam nefosforasi ziya kubambana zize zibhinqike ziphume kwisisombululo njengodaka olungenyibiliki emazantsi etanki lakho.
- Zalisa itanki lakho ulishiye livulekile iiyure ezingama-24 ukuze ikloriyini enyibilikayo iphume.
- Yongeza i-asidi yefosforikhi okanye i-asidi yenitrikhi eyenziwe yabuthathaka (i-pH Down) ngezixa ezincinci de amanzi ehle aye ku-pH 6.0–6.2.
- Linda imizuzu engama-30 ukuze i-asidi isebenzisane neekhabhoneyithi phambi kokuba ufake izichumiso zakho.
Inyathelo 3: Balela ikhalsiyam nemagnesiyam esele ikho
Ukuba amanzi akho omthombo anobulukhuni obuphezulu beeminerali, izityalo zakho sele zifumana umthamo ozinzileyo wekhalsiyam (Ca) nemagnesiyam (Mg) enyibilikileyo. Ukuba uxuba iityuwa ezomileyo ukusuka ekuqaleni, uhlala unako ukunciphisa isahlulo se-Calcium Nitrate ne-Magnesium Sulphate (ityuwa ye-Epsom) kule resiphi nge-15% ukuya kwi-25%, uvule indawo yee-Potassium Nitrate ne-Mono-Potassium Phosphate ezingakumbi ngaphandle kokunyusa i-EC ipheleleyo.
Ukuba usebenzisa ukutya okuluqhoqhoqho okuxutywe ngaphambili kwiinxalenye ezimbini, khetha ifomyula ye-"Hard Water" ukuba iyafumaneka, okanye usebenzise nje i-80% yomlinganiselo oqhelekileyo ocetyiswayo ngelixa ubeka esweni umbala wamagqabi.
Inyathelo 4: Nciphisa umjikelo wokuchitha itanki lakho
Kwinkqubo ejikelezisa amanzi (i-NFT okanye i-Dutch bucket), izityalo zikhupha amanzi acocekileyo ngamagqabi ngelixa zifunxa ii-ion ezithile kuphela. Izinto ezisetyenziswa kancinci sisityalo—ezinjengesodiyam nekloraydi evela emanzini empompo—zisala etankini.
Ukuba ugcwalisa nje itanki ngamanzi empompo ama-400 PPM nezondlo ezitsha, ezo tyuwa zingabalulekanga zangasemva ziya kuqina ekuhambeni kwexesha. Itanki eliqala kumgangatho osisiseko wama-400 PPM linokuthi lidlule lula kumgangatho osisiseko wama-900 PPM emva kweeveki ezimbini zokugcwalisa. Ukuthintela oku, chitha itanki ngokupheleleyo nge-100% uze ulizalise kwakhona rhoqo ngeentsuku ezili-10 ukuya kwezili-14 endaweni yokuqhuba imijikelo yokugcwalisa engapheliyo.
Ukwakha ukunyamezela kwiinkqubo zeklasi
Ukusebenza namanzi kamasipala ehlabathi lokwenyani sesinye sezona zifundo ziluncedo zenzululwazi esetyenziswayo esinikwa sisixhobo se-hydroponics. Siguqula umsebenzi olula wokulima esitiyeni ube yikhemistri esebenzayo, sibonisa ukuxineka kwee-ion, ulungelelwano lwe-osmosis, kunye nokulinganiswa kweesensa. Ukuba uyila okanye ulungisa iinkqubo zegumbi lokufundela, iikhithi neesensa ze-hydroponics zethu ezizodwa ziquka izixhobo ze-EC nezi-pH ezilinganisiweyo ezisetwe ngokukodwa ukuba ziphathe ngokuthembekileyo imigangatho esisiseko enemineral ephezulu.
