Kuongorora Hunhu hweMvura yeKudiridza
Kushandiswa kwemvura pakudiridza chinhu chakakosha pakubudirira kwekurima, kunyanya munzvimbo dzine mvura isingawanzonaya. Hunhu hwemvura inoshandiswa pakudiridza hunokanganisa zvikuru kubereka kwevhu, kukura kwezvirimwa, uye kuenzana kwenzvimbo dzekurima. Nokudaro, kuongorora hunhu hwemvura yekudiridza chinhu chakakosha pakuronga nekugadzirisa zviwanikwa zvekurima.
Kukosha Kwemhando Yemvura Mukudiridza
Mvura yekudiridza inofanira kuzadzisa zvimwe zvinodiwa kuti ive nechokwadi chekuti zvirimwa zvinokura zvakanaka pasina kukuvadza chimiro chevhu kana hutano hwezvirimwa. Mvura isina kunaka inogona kunge iine zvinhu zvinokuvadza zvakaita semunyu, simbi dzinorema, uye tupukanana tunogona kuparadzira zvirwere zvezvirimwa. Izvi zvinogona kukonzera kudzikira kwegoho rezvirimwa uye kutoisa panjodzi hutano hwevanhu vanodya zvirimwa zvakasvibiswa.
Zvinoyera Hunhu hweMvura paKudiridza
Zvinotevera ndezvimwe zvezvinhu zvikuru zvinowanzo ongororwa kuti zvionekwe kuti mvura inodiridza zvakanaka sei:
1. Hunyoro:
Munyu, kana kuti munyu uri mumvura, chimwe chezvinhu zvikuru zvinosarudza kunaka kwemvura yekudiridza. Mvura ine munyu wakawanda inogona kukonzera matambudziko kumiti nekuti munyu wakawandisa unogona kudzivirira kutorwa kwemvura uye zvinovaka muviri nemidzi yemiti. Izvi zvinowanzoonekwa uchishandisa electrical conductivity (EC).
2. Chiyero cheKusveta Sodium (SAR):
SAR ihuwandu hwesodium muvhu zvichienzaniswa necalcium nemagnesium mumvura yekudiridza. SAR yakawanda inogona kuwedzera kupararira kwevhu revhu, zvichideredza kupinda kwemvura uye zvichikonzera matambudziko emvura.
3. pH:
pH yemvura inokanganisa zvakananga kuwanikwa kwezvinovaka muviri muvhu. Mvura yekudiridza ine acid yakawanda (pH yakaderera) kana alkaline yakawanda (pH yakakwira) inogona kukanganisa kuenzana kwekudya kwechirimwa.
4. Kuvapo kweZvinhu zveSimbi:
Dzimwe simbi dzinorema, dzakadai se lead, arsenic, cadmium, uye mercury, dzinogona kuva chepfu kumiti kunyangwe kana dziine huwandu hushoma. Saka, kuongorora huwandu hwesimbi dzinorema kwakakosha.
5. Nitrates nePhosphates:
Zvinovaka muviri zviri mumvura, zvakaita senitrate nephosphate, zvakakosha pakukura kwezvirimwa. Zvisinei, huwandu hwakawanda hwemvura hunogona kukonzera kusvibiswa kwevhu uye eutrophication kana mvura ikayerera ichipinda muzvisikwa zvemumvura.
6. Zvirwere Zvinokonzera Utachiona:
Mvura inoshandiswa pakudiridza haifanirwe kunge iine tupukanana tunokonzera zvirwere zvezvirimwa kana kutosvibisa zvigadzirwa zvinobva mazviri.
Nzira dzekuongorora Hunhu hweMvura
Kune nzira dzakasiyana-siyana dzinogona kushandiswa kuongorora kunaka kwemvura yekudiridza, kubva pahunyanzvi hwemurabhoritari hwakaoma kusvika panzira dziri nyore dzemumunda.
1. Spectrophotometry:
Inoshandiswa kuyera huwandu hwesimbi dzinorema nezvimwe zvinhu zvemakemikari mumvura. Nzira iyi inobvumira ongororo yakarurama uye mhedzisiro inokurumidza.
2. Potentiometry:
Nzira iyi inobatsira pakuyera pH yemvura. Chishandiso chinowanzoshandiswa i pH meter, iyo inogona kuverenga zvakananga acidity yemvura kana alkalinity.
3. Kuyera maitiro ekuita zvinhu:
Inoshandiswa kuyera kufambiswa kwemvura nemagetsi, izvo zvinoratidza kuti ine munyu. Chishandiso chinoshandiswa i conductorivimeter.
4. Kuongororwa kweMass Spectroscopy:
Nzira iyi inopa ongororo yakadzama yemhando uye huwandu hwesimbi dzinorema mumvura yekudiridza. Kunyangwe ichidhura, mass spectroscopy inopa mhedzisiro chaiyo.
5. Zvidikidiki:
Kuongororwa kwemicrobiological kunoshandiswa kuona kuvapo kwetupukanana tunokonzera zvirwere mumvura, kusanganisira mabhakitiriya, mavhairasi, uye fungi. Nzira dzakajairika dzinosanganisira cultures dzetupukanana uye nzira dzemamorekuru dzakadai sePCR.
Kukanganiswa Kwehunhu Hwakashata hweMvura
Kusashanda zvakanaka kwemvura kunogona kuva nemigumisiro yakaipa yakasiyana-siyana:
1. Kuderera kweKubudirira:
Mvura ine munyu wakawanda kana kuti ine pH isina kukodzera inogona kukanganisa kukura kwezvirimwa uye kuderedza goho rezvirimwa.
2. Kukuvadzwa kweMaumbirwo eIvhu:
Kuwanda kweSAR kunogona kukonzera kuti ivhu riome uye riome kurima, zvichikanganisa kupinda kwemvura nemidzi yemiti.
3. Kusvibiswa Kwezvikafu:
Kuwanda kwenitrate nephosphate kunogona kusvibisa mvura yepasi pevhu nemvura dzakapoteredza, zvichikonzera kupararira kwemvura uye kukanganisa kuenzana kwenzvimbo dzemumvura.
4. Zvirwere zveMiti:
Utachiona hunokonzera hutachiona mumvura yekudiridza hunogona kukonzera zvirwere zvakasiyana-siyana zvezvirimwa zvinogona kuderedza goho rezvirimwa uye kutoparadza zvirimwa.
Matanho Ekutarisira
Kutarisira kunaka kwemvura yekudiridza kunoda nzira yakabatana inosanganisira kutarisa uye kurapwa kwemvura. Heano mamwe matanho aunogona kutora:
1. Kutarisa Nguva Nenguva:
Kuongororwa kwemhando yemvura nguva dzose kwakakosha kuti uone shanduko mumakemikari uye zvipenyu mumvura yekudiridza.
2. Kurapa Mvura:
Nzira dzekurapa dzakadai sekubvisa munyu, kusefa, uye kushandisa makemikari kuderedza pH zvinogona kushandiswa kuvandudza kunaka kwemvura yekudiridza.
3. Kushandisa Mamwe Matsime Emvura:
Kushandisa mvura yemvura inonaya kana mvura yakasviba yakarapwa zvakare kunogona kuva mhinduro yekukunda kushomeka kwemvura yemhando yepamusoro.
4. Kusarudzwa kweMiti Isingapindi Munyu:
Kudyara miti inotsungirira munyu zvakanyanya uye mamiriro emvura asina kunaka kunogona kubatsira kuderedza kukanganiswa kwehunhu hwemvura husina kunaka.
Mhedziso
Hunhu hwakanaka hwemvura hwakakosha pakudiridza zvinobudirira uye zvinogara kwenguva refu. Nokudaro, kuongorora kwakadzama uye kutarisirwa kwakanaka kwezviyero zvehunhu hwemvura kunofanirwa kuve chinhu chikuru mumabasa ekurima. Pasina kuedza kwakadaro, kuchengetedzeka kwekurima uye hutano hwezvakatipoteredza nevanhu vanovimba nezvigadzirwa zvekurima zvinogona kukanganiswa. Nokudaro, kunzwisisa nekugadzirisa hunhu hwemvura yekudiridza chinhu chakakosha mukubudirira kwenguva refu kwechikamu chekurima.
