Kodi kudziwa acidity ya nthaka?

Nthawi zambiri zimakhala zofunikira kudziwa acidity ya nthaka yobzala maluwa kapena masamba. Ndi kuchuluka kwa laimu pansi ndipo amatchedwanso acid-base base. Ziyenera kukhala zabwino kwambiri kwa zomera kuti zimve bwino zakudya zonse, ndipo zokolola zinali zabwino komanso zowonjezera. Kuyika kwa acidity kuli mitundu ikuluikulu isanu: kuchokera ku dothi lolimba kwambiri (3-4 pH) kuti likhale lamchere kwambiri (8-9 pH). Kusalowerera ndale kumatengedwa ngati nthaka ndi acidity ya 6-7 pH.

Kodi mungayeze bwanji acidity ya nthaka?

Kuti mudziwe malo omwe ali pa tsamba lanu, yesani njira imodzi zotsatirazi:

• kugwiritsa ntchito chipangizo chapadera choyezera acidity ya nthaka - imatchedwa mita ya asidi;
• ngati pa webusaiti ya chaka chatha sichikula kanthu, ndiye tcherani khutu ku zomera zomwe zakhazikika m'dziko lino. Nthaŵi zochepa zowonongeka kapena zosaloŵerera m'madera nthawi zambiri zimakhala mu clover, nettle , bindweed, amayi ndi abambo opeza. Ndipo pa kwambiri acidic, nayenso, pansies, horsetail, plantain, buttercup kukula;
• Zidzathandiza kudziwa kuti asidi a nthaka, osakwanira, vinyo wosasa. Kuti muchite izi, dulani madontho pang'ono a madziwa pamtunda pang'ono ndikuwona zomwe zimachitika. Ngati pali chikhalidwe chake chokha ndi zowawa, monga ngati soda yotsekemera - ichi ndi chizindikiro chakuti nthaka salowerera kapena pafupi ndi zamchere. Ngati palibe zizindikiro zotere, ndiye kuti acidity ya nthaka ndi yaikulu. Kuti mubwezeretsenso, muyenera kuwonjezera ufa wamchere, choko kapena dolomite kumtunda wotere;
• yesani ndi currant yakuda. Tengani masamba pang'ono kuchokera ku chitsamba cha chomera ichi ndipo mudzaze ndi madzi otentha. Pamene madzi asema, sakanizani masamba ndi supuni, ndipo pang'onopang'ono mudzanike pang'ono mu galasi, momwe mukufunikira kuyesa. Zotsatira zake ziyenera kuweruzidwa ndi mtundu wa madzi: zidzasanduka zofiira (izi zikutanthauza kuti dothi limakhala lolimba kwambiri), pinki (sing'anga-asidi), wobiriwira (osalowerera) kapena mthunzi wa buluu (zamchere).

Madzi a Kutentha kwa Dothi

Chipangizo chophweka chodziwira kuti acidity ya nthaka ikhoza chitani nokha. Ichi si chida, komabe ndi njira yowerengeka, yomwe, komabe, ili ndi ntchito yabwino ndi ntchitoyi.

Chofunika cha njirayi ndi kukonzekera ngongole za litmus. Izi zatheka. Pukutani mutu wa zofiira (violet) kabichi ndi kukonzekera decoction kuchokera pamenepo, momwe kuli kofunika kuti zilowerere pepala lopangira kwa kanthawi kochepa. Pambuyo pake, mutha kuyesa kuyesa pH ya nthaka. Ingolani nyemba zoumba ndi kuzikaniza mu chiwongolero pamodzi ndi pepala lowonetsera, kuti likhale lokongola kwambiri. Mtundu umene pepalayo wadetsedwa, ndipo adzakuuza za acidity ya nthaka. Mtundu wofiira wa pepala umatsimikizira kupezeka kwa asidi, ndi wobiriwira ndi wabuluu - alkali.
