Mhedzisiro yepH pakukura kwezvirimwa
Pendauluan
pH, kana kuti "mukana weHydrogen," chiyero cheacidity kana alkalinity yemushonga, unoratidzwa pachikero che0 kusvika 14. Chikero ichi chakakosha munzvimbo dzakasiyana dzesainzi, kusanganisira kurima. Pachikero ichi, kukosha kwe7 kunoonekwa sekwakarerekera, kukosha kuri pasi pe7 kune acidic, uye kukosha kuri pamusoro pe7 kune basic (alkaline). Muchirevo che kukura kwezvirimwa, pH yevhu ine basa rakakosha zvikuru.
Zvirimwa zvinoda mamiriro chaiwo ekukura zvakanaka, uye pH yevhu chinhu chakakosha pakuchengetedza nharaunda chinokanganisa kuwanikwa kwezvinovaka muviri, mashandiro ehutachiona hwevhu, uye kusangana kwemakemikari ari muvhu. Chinyorwa chino chichatsanangura kuti pH inokanganisa sei kukura kwezvirimwa uye kuti matanho angatorwa sei kugadzirisa pH yevhu.
Kunzwisisa pH uye Hukama Hwayo Nevhu
pH yevhu chiratidzo chakakosha cheacidity kana alkalinity yevhu. Ivhu rine pH yakaderera (acidic) rine huwandu hwakawanda hwehydrogen ions, nepo ivhu rine pH yakakwira (alkaline) rine huwandu hwakawanda hwehydroxide ions. Mazhinji acho. kurima zvirimwa yakanaka ine pH iri pakati pe5,5 kusvika 7,5.
pH yevhu inokanganisa kuwanikwa kwezvinovaka muviri uye tupukanana twevhu. Pamazinga epH akanyanya (aine acid yakawanda kana kuti alkaline yakawanda), zvinovaka muviri zvakawanda zvinokosha zvinova zvishoma kuzvirimwa kana kutovharirwa. Nekuda kweizvozvo, zvirimwa zvinogona kusangana nekushomeka kwezvinovaka muviri kunyangwe zvazvo zvinovaka muviri izvi zviripo muvhu.
Mhedzisiro yepH paKuwanikwa kweNutrient
Kuwanikwa kwezvinovaka muviri muvhu kunokonzerwa zvikuru ne pH. Heano mimwe mienzaniso mikuru:
– Pa pH 5,5 – 7, zvirimwa zvinowana macronutrients akawanda akadai senitrogen (N), phosphorus (P), uye potassium (K).
– Semuenzaniso, phosphorus inowanikwa zviri nyore kana pH iri pakati pe6,0 ne7,0. Kana pH iri pasi (ine acidic), phosphorus inenge yakavharirwa muchimiro chemineral, zvichiita kuti zviomere zvirimwa kuwana.
– Zvinhu zvinovaka muviri zvakaita sesimbi (Fe) uye manganese (Mn) zvinowanzowanikwa zvakanyanya muvhu rine acidic, asi muvhu rine alkaline zvinogona kusawanikwa zvakanyanya, zvichikonzera kushomeka kwezvinovaka muviri muzvirimwa.
Saka, kuchinja kudiki kwe pH yevhu kunogona kukanganisa kukura kwezvirimwa nekuchinja kuwanikwa kwezvinovaka muviri muvhu.
Mhedzisiro yepH paBasa reZvipembenene
Zvipembenene zvemuvhu zvinokanganiswawo zvakanyanya ne pH. Mabhakitiriya, ayo anokonzera zvakawanda maitiro akakosha evhu akadai sekuora kwezvinhu zvipenyu uye kugadzirisa nitrogen, dzinowanzo shanda zvakanyanya pa pH isina kusimba kusvika kune alkaline zvishoma. Kusiyana neizvi, howa dzemuvhu dzinogona kutsungirira pH yemuvhu ine acid yakawanda.
Kugara pamwe chete kwehutachiona hwakaenzana kwakakosha pahutano hwevhu nemiti. Utachiona uhu hunobatsira mukuburitswa kwezvinovaka muviri, kuora kwezvinhu zvipenyu, uye kudzora zvirwere zvevhu. Kana pH yevhu yakaderera zvakanyanya kana kuti yakakwira zvakanyanya, mashandiro eutachiona uhu anogona kuderedzwa, zvichigona kukanganisa hutano hwevhu nemiti.
Mhedzisiro yepH paMaumbirwo eIvhu uye Kuwanda kwaro
pH yevhu inokanganisawo chimiro chevhu. Semuenzaniso, muvhu rine acidic, maion earuminiyamu nesimbi anogona kuwanda zvakanyanya, izvo zvinogona kuderedza kugona kwevhu kupinza mvura nemhepo, pamwe nekuderedza nzvimbo yemaburi. Nekuda kweizvozvo, kukura kwemidzi uye kushanda zvakanaka kwemvura nekudya zvinovaka muviri nemiti zvinogona kukanganisika.
Kusiyana neizvi, kana pH iri alkaline zvakanyanya, kunyudzwa kwecalcium muvhu kunogona kuwedzera, zvichikonzera kuumbwa kwevhu rakaomarara uye rakamanikana. Izvi zvinogona kudzikamisa kukura kwemidzi uye kugona kwemuti kuwana mvura nezvinovaka muviri.
Kutarisira pH yevhu
Kuziva kukosha kwe pH mu kukura kwezvirimwaVarimi nevarimi veminda vanofanira kutarisa nekutarisira pH yevhu ravo. Heano mamwe matanho avanogona kutora:
1. Kuyera pH yevhu:
Kuti uone pH yevhu, bvunzo dzevhu dzinodiwa nguva nenguva. Zvishandiso zvekuyedza pH yevhu zvinowanikwa kutengeswa uye zvinopa kuverenga kwakarurama.
2. Inowedzera acidic ivhu pH:
Kana ivhu rine acid yakawanda, lime (limestone) inowanzo wedzerwa kuti pH iwedzere. Mhando dze lime dzinonyanya kushandiswa ndi calcite (calcium carbonate) uye dolomite (musanganiswa wecalcium nemagnesium carbonates). Huwandu hwe lime hunowedzerwa hunoenderana neacidity yevhu uye rudzi rwaro.
3. Kuderedza pH yevhu reAlkaline:
Kuderedza pH yevhu rine alkaline yakawanda kunogona kuva kwakaoma. Dzimwe nzira dzinosanganisira kuwedzera zvinhu zvakasikwa zvakaita secompost kana acidic peat moss, izvo zvinoderedza pH zvishoma nezvishoma. Kuisa sulfur kana aluminium sulfate kunogonawo kubatsira kuderedza pH yevhu.
4. Kutarisa uye Kugadzirisa:
Kana pH inodiwa yawanikwa, kutarisirwa nguva nenguva kunofanira kuitwa kuti ive nechokwadi chekuti inoramba iri mukati mehuwandu hwakakwana. Zvinhu zvemuvhu zvinofanira kuwedzerwa nguva nenguva kuti ivandudze chimiro chevhu uye kubereka kwaro.
Penutup
pH yevhu inokanganisa zvakananga kuwanikwa kwezvinovaka muviri, mashandiro ehutachiona, uye chimiro chevhu, zvese izvi zvinobatsira pahutano nekukura kwezvirimwa. Nokudaro, kunzwisisa nekugadzirisa pH yevhu idanho rakakosha mukurima nekurima bindu zvinobudirira.
Kunyange hazvo kutarisira pH yevhu kuchigona kuoma, nekunzwisisa kwakanaka uye zvishandiso zvakakodzera, varimi nevarimi veminda vanogona kuona kuti zvirimwa zvavo zvinokura zvakanaka mumamiriro ezvinhu akanaka. Nzira dzekutarisira dzakadai sekuongorora ivhu nguva dzose uye kuwedzera kugadziriswa kwevhu inzira dzakakosha dzekuwana pH yakaringana inotsigira zvirimwa zvine hutano uye zvinobereka. Nokudaro, pH yevhu yakanaka inobatsira kwete chete kuhutano hwezvirimwa zvega zvega asiwo kuhupenyu hwese hwenzvimbo yevhu.
