Chii chinonzi pH uye chinokanganisa sei zvirimwa?
pH iri a kuyera kubva ku0 kusvika ku14 iyo inoratidza mwero we acidity kana alkalinity yevhu. A pH ye7 haina kwayakarerekera, pazasi payo ine acidic, uye pamusoro payo ine alkaline. Zvizhinji zvezvirimwa zvekurima uye zvirimwa zvinosarudza ivhu risina kwarakarerekera kana rine acidic zvishoma., pakati pe6 ne7. Zvisineyi, pane zvinosiiwa zvinocherechedzwa, uye zvakakosha kuti uzive huwandu hwakakwana hwemhando yega yega. Kuti udzidze zvakawanda nezvekuti pH inobata sei hutano hwezvirimwa zvako, unogona kutarisa gwara redu pa kukosha kwevhu pH pamiti.
Ivhu rine pH isina kukwana rinogona kukonzera kushaya zvokudya zvinovaka muviri, kunyange kana chikafu chiripo, nokuti midzi haigoni kuitora nyore nyore. Pazasi pane tafura yekutungamira yepH mazinga uye zvazvinoreva:
| pH range | Kurongwa | Descripcion |
|---|---|---|
| <4.5 | Yakanyanya acidic | Matambudziko akanyanya ekutorwa kwechikafu. |
| 4.5 - 5.5 | Acid | Inokodzera zvirimwa zve acidophilic. |
| 5.6 - 6.5 | acidic zvishoma | Yakanakira zvirimwa zvakawanda. |
| 6.6 - 7.3 | Kusarerekera | Yakanakira miriwo uye zvirimwa zvakawanda. |
| 7.4 - 8.4 | Alkaline zvishoma | Inogona kudzikisira kuwanikwa kwechikafu chakadai sephosphorus. |
| 8.5 - 9.0 | Alkaline | Ivhu rine dambudziko rezvirimwa zvakawanda. |
| > 9.0 | Yakanyanya alkaline | Chete yakakodzera zvirimwa chaizvo. |
Edza pH yemunda wako
Nhanho yekutanga yekugadzirisa ivhu pH ndeye kuyera kukosha kwayo ikozvinoUnogona kuita izvi nyore kumba uchishandisa:
- Mvura yakasvibiswa
- Shovel
- Purasitiki mudziyo
- pH mitsetse (inowanikwa kuma pharmacy uye zvitoro zvakakosha)
Iwo ma test strips anokupa iyo pH kukosha kuburikidza nekuchinja kwemavara kunofananidzwa nechiyero chemugadziri. Yeuka kuti pH inogona kusiyana zvichienderana nekudzika uye nzvimbo yebindu. Naizvozvo, iyo yakanaka ndeye:
- Gurai nyika munzvimbo dze 1-2 m².
- Bvisa samples kubva munzvimbo imwe neimwe kusvika pakadzika 45 cm; yemiti, dhirai pasi kusvika 80 cm.
- Sanganisa ese samples zvakanaka.
- Sanganisa zvikamu zvakaenzana zvevhu nemvura yakasvibiswa, mirira kuti igare, uye shandisa mutsara kuyera pH.
Iwe unogona zvakare kushandisa ku Laboratory analysis kuitira kunyatsojeka, kunyanya mumabasa ekurima.
Nzira yekuderedza pH yevhu?
Kana ivhu rako rine a High pH (inopfuura 7) uye iwe unofanirwa kuiisa acidify, une dzimwe nzira dzinoverengeka dzinoshanda:
- Blond peat: pH yayo ine acidic, uye kana yakasanganiswa nevhu (4-5 cm layer), inobatsira zvishoma nezvishoma kudzikisa pH. Dzokorora kuyerwa mushure memwedzi mishoma.
- Aluminium sulfate: Inopa kukurumidza kuderedzwa kwepH. Kazhinji, 0,5 kg per square metre inodzikisa pH nepoindi imwe. Inonyanya kushandiswa yakanyungudutswa mumvura.
- Sulfur yekurima: Iyo inzira yehupfumi uye inoshanda; inononoka oxidize kuumba sulfuric acid, ichideredza pH nekufamba kwenguva. Shandisa pakati pe0,5 ne1 kg/m², uchitarisa pH mwedzi mitanhatu yega yega.
- Iron sulphate: Mukuwedzera kune acidifying, inopa simbi inofanana uye inorwisa iron chlorosis. Isa magiramu maviri kusvika mana parita yemvura.
- Organic zvinhu: Kubatanidza mupfudze, manyowa, kana tsvina yezvirimwa zvinogona kubatsira kuita acidify ivhu, kuvandudza chimiro charo uye kubereka.
Sarudzo yechigadzirwa uye chipimo chemushonga chinozogara chichienderana nekuvharisa kwevhu (kugona kwaro kuramba pH shanduko), pamwe nekugadzirwa kwayo uye huwandu hwezvinhu zvipenyu.
Nzira yekusimudza sei pH yevhu?
Muvhu ne Low pH (5 kana pasi), kunyanya kana uchizodyara mhando dzinonzwa acidity, senge almond kana carob miti, zvinodikanwa kusimudza pH:
- Potassium carbonate: Yakanyanya soluble uye inoshanda. Inogona kushandiswa kuburikidza nekudiridza; chipunu chidiki chinokwana kusimudza pH panzvimbo diki.
- Agricultural lime (ground limestone): Iyi ndiyo inonyanya kugadziriswa. Inofanira kuiswa mukati mepamusoro pe 15-20 cm yevhu. Huwandu hunosiyana zvichienderana nekuumbwa kwevhu uye cation exchange capacity; ivhu revhu uye organic rinoda madosi epamusoro.
- Dolomite: Mukuwedzera kune calcium, inopa magnesium. Inokurudzirwa kana ivhu zvakare rakashata mune chikafu ichi.
- Basalt hupfu: Inokodzera dosing iyo pH kuwedzera uye kugadzirisa chimiro.
- Quicklime: Inongokurudzirwa zviito zvekukurumidza uye pasi pekutariswa, sezvo inogona kukonzera kuwedzera kamwe kamwe mupH.
Kunyorera kunofanirwa kuitwa mumatsutso kana mukutanga kwechirimo, uye kudyara nekukurumidza mushure mekuisa liming kunofanirwa kudzivirirwa kuitira kuti pave nehomogeneous reaction.
Zvinhu zvinokanganisa pH kugadzirisa
La huwandu hwekugadzirisa huchashandiswa (lime, sarufa, zvichingodaro) zvinoenderana nezvakati wandei:
- cation exchange capacity (CEC): Ivhu rine CEC yakakwirira, rakaita sevhu kana ivhu rine organic matter yakawanda, rinoshingirira kusanduka kwepH uye rinoda chimwe chigadzirwa.
- Kuchena uye granulometry: Iyo yakanakisa uye yakachena ma correctors (kunyanya lime), iyo inonyanya kushanda uye nekukurumidza kuita kwavo.
- Nzvimbo yekushandisa: Zvakakosha kusanganisa corrector muchikamu chinoshanda chevhu apo midzi inokura.
Dzivisa kugadzirisa pH nekukurumidza. Inokurudzirwa kugadzirisa imwe pH point pagore Kudzivirira kukanganisa kune microorganisms nemidzi. Tarisa pH nguva nenguva uye dzokorora zvikumbiro kana zvichidikanwa.
Ivhu rine pH isiriyo rinoratidza zviratidzo zvinooneka muzvirimwa, zvakaita semashizha ekuyero (chlorosis), kusakura zvakanaka, kusakura zvakanaka kwemaruva, uye kutadza kutora kudya kwakadai se iron, phosphorus, calcium, kana magnesium. Uyezve, kuwanda kwemamwe masora kunogona kuratidza kuwandisa acidity. Kuti udzidze maitiro ekuona zviratidzo izvi muzvirimwa zvako, shanyira chikamu chedu pa zvirimwa nevhu.
Kugadzirisa pH kwakaringana, uchishandisa michina, organic kana inorganic nzira, inobvumira:
- Kushandisa mafetireza zviri nani
- Dzivisa kushomeka kwezvokudya zvinovaka muviri
- Kurudzira kuvandudzwa kwema microorganisms anobatsira
- Gadzirisa kushanda uye hutano hwemhando dzose dzezvirimwa
Kugadzirisa ivhu pH kwakakosha kuti rienderane nezvinodiwa nechirimwa chimwe nechimwe uye kuona kuti zvirimwa zvinokura zvakasimba uye zvine hutano. Nekushandisa matekiniki akakodzera uye nekunzwisisa hunhu hweivhu rako, unozogadzira nharaunda yakanaka yezvirimwa zvako, zvichikonzera goho riri nani uye magadheni ane simba.
