Ungachinja sei ivhu pH

Ivhu rakakosha zvakakosha kumiti, kwete pasina, mariri mune zvicherwa zvavanoda zvakanyanya kuti zvikure. Asi dzimwe nguva tinowana ivhu rakaomarara kana rine alkaline, iro, pane kubvumira midzi kuti ivapinze, rinovaita kuti vashaye simba, vachiisa pangozi hupenyu hwemiriwo. Izvi zvinogona kudzivirirwa munzira ipi neipi kuti zviitike?

Neraki, hongu. Pane chinhu chimwe chete chatinogona kuita kuti pave nemunda wakanaka kana munda wemichero pane iyo ivhu. Nezve izvo, iwe unofanirwa kuziva kuchinja sei ivhu pH, chimwe chinhu chatinozotsanangudza kwauri zvinotevera.

Ndeupi musiyano uripo pakati pevhu realkaline neasidhi imwe?

Usati waziva shanduko iyo pH, zvinodikanwa kuti uone kuti nei tichifanira kuchichinja.

Alkaline ivhu

Kana isu tine ivhu realkaline, ndiko kuti, ivhu rine pH iri manomwe kana kupfuura, mimwe michero vanozove nekushomeka kwezvicherwa zvakakosha seyimbi, mhangura, manganese uye zinc. Pamusoro pezvo, mhando yeivhu iyi ine katsika kekuti ibatanidzwe zvakanyanya, zvinodzivirira mvura kubva mukukasira nekukasira sekuda.

Acid ivhu

Kana isu tine ivhu revhu, kureva kuti, nyika ine pH iri pasi pe7, dambudziko rinosangana nezvimwe zvirimwa nderekuti hauwani - kana haugone kunwa - phosphorus, calcium, boron, molybdenum kana magnesium, ayo akakosha zvicherwa pakukura kwayo.

Ungachinja sei pH yevhu?

Alkaline ivhu

Kana tichida kushandura pH yevhu realkaline kuti riite riine acidic, tinogona kushandisa zvinotevera:

• Poda sarufa: mhedzisiro yacho inononoka (kubva pamwedzi mitanhatu kusvika pamisere), asi kuve wakachipa chaizvo ndizvo zvinonyanya kushandiswa. Tinofanira kuwedzera 6 kusvika 8g / m150 uye kusanganisa nevhu, uye kuyera pH nguva nenguva.
• Iron sulphate: ine simba rinokurumidza kupfuura sarufa, asi zvinodikanwa kuyera iyo pH sezvo isu tichigona kuidzikisa kupfuura zvakafanira. Muyero wekudzikisa iyo pH 1 degree i4 magiramu esimbi yakaumbwa nesirita yemvura.
• Blond peat: ine asidi yakawanda pH (3.5). Tinofanira kuisa 10.000-30.000kg / ha.

Acid ivhu

Kana, kune rumwe rutivi, tichida kusimudza pH yevhu rakaoma, tinogona kushandisa zvinotevera:

• Pasi reraimu: tinofanirwa kuiparadzira nekuisanganisa nenyika.
• Calcareous mvura: yakakurudzirwa kusimudza iyo pH chete mumakona madiki.

Mune chero mamiriro ezvinhu isu tinofanirwa kuyera pH, nekuti kana tiri kukura acid michero (japanese maples, camellias, nezvimwewo) uye isu tinosimudza iyo pH kune anopfuura matanhatu, ipapo ivo vanoratidza zviratidzo zvechlorosis nekuda kwekushaikwa kwesimbi.

Saka unogona kurima zvirimwa zvaunoda mubindu rako kana munda wemichero 🙂.
