Chifukwa zokolola osauka - acidic nthaka. Kodi kuchita kwa chonde ya dziko?

An chizindikiro zofunika a chonde a dothi - acidity ake. Quantitatively, izo amalifotokoza pH - kufunika pH (a muyezo wa ntchito ayoni wa hydrogen). Nthaka acidity ndi mfundo pH mu osiyanasiyana kuchokera 6.1 kuti 7,0 - ndale, ndi yabwino kwambiri chifukwa zosiyanasiyana zomera, kuyambira zinthu zimenezi zilipo kwa iwo mchere wofunika. zinthu zabwino kwa zomera amalenga nthaka acidity ali pafupi ndi ndale (pH zosakwana 6 koma woposa 5.5). Zamchere maiko ammwamba (pH kuposa 7.1), achepetsa kuthekera zinthu chomera zakudya monga chitsulo, potaziyamu, mkuwa, phosphorous, nthaka, magnesium, ndi boron. M'madera zamchere mu zomera ku yambiri molybdenum izo zifika, ndipo kumabwezera mmbuyo chitukuko. Monga alkalinity ndi acidity bwanji khalidwe la nthaka. Iwo chatsitsa zosefera ndi breathability. nthaka acidification ndi pH a zosakwana 5.5. Ngati kufunika pH ndi 5.5, koma oposa 5.1, nthaka pang'ono asidi; modekha nthaka pa pH mu osiyanasiyana 5.0 - 4.6; mwamphamvu - pa pH 4.5 - 4.1, ndi amphamvu kwambiri - pH zosakwana 4.0. Kukula kwa dongosolo muzu mbewu monga lonse liwiro, zokolola amachepetsa nthaka acidic. Kodi kuchita, chifukwa malo acidic ndi chimawononga tizilombo opindulitsa nthaka,, nyongolotsi. Pa rhizomes nyemba si kudziunjikira m'nthaka asafe acidic nthaka. acidic dongosolo nthaka wathyoka. kumalepheretsa kwambiri kupeza mchere zomera nthaka: phosphorous, potaziyamu, magnesium ndi calcium - koma nthawi yomweyo kumawonjezera otaya m'menemo radionuclides, ayoni zotayidwa, manganese, chitsulo, zitsulo acidic nthaka.

Kodi kuchita kudziwa acidity wa nthaka?

The acidity wa nthaka akhoza titsimikize paokha, popanda kutsatira zasayansi agrochemical. Molondola kudziwa pH wa nthaka, ntchito ya pepala litmus. Pali Zinthu. The lactic mwana botolo ndi mwambo womaliza maphunziro kudzaza kwa mlingo wa nthaka Mzere wachiwiri sieved, kudzaza ndi madzi isanafike magawano chachisanu ndi kutsanulira 1/2 choko ufa. Ndiyeno kukokera pa khosi la mphira nipple, chisanadze mpukutu izo mwamphamvu. Nyuzipepala kukulunga botolo ndi kugwedeza kwa mphindi zisanu. Ndi kulabadira ndi choko zidulo nthaka adzamasula carbon dioxide, kulenga kuthamanga. Ngati acidity wa nthaka ndi ofooka, ndiye anapotoza nipple adzachira pang'ono, ndipo inflates ndi acidity amphamvu. Pali njira zithunzi, amene sakhala zolondola. Namsongole dothi acidic amatiuza za mlingo wa acidity. Pa dothi pang'ono acidic amati ngati zomera chizindikiro ngati bedi udzu, dandelion, zoyera clover, mfundo-udzu, mitengo chotchezera, mayweed, Ranunculus repens. Pa modekha kuwuka Viola galu, clover analima munda, plantain, chilombo chotchezera, chilombo timbewu. Kwambiri nthaka acidic yokutidwa ndi horsetail, thonje udzu, mphamvu mphakayu, schavelkom yaing'ono. Ngati kasupe wa dziko yaitali Dries, kenako kupukuta mofulumira ndipo zokhakhala zooneka ngati bowa, izi zikusonyeza kuti pali acidic nthaka.

Kodi kuchita kwa n'chongoletsa nthaka

Amachepetsa acidity wa laimu dothi. Kuti zimenezi zitheke, oyenera hydrated laimu, womwe wapangidwa mu kasupe ndi autumn pamaso yolima. Laimu akhoza m'malo ndi choko wophwanyidwa, phulusa, marl. Pamaso liming kusangalala mabukhu pa mlingo zomveka ndiponso zokwanira kupanga mankhwala kuti m'kati liming asakhale acidic dothi zamchere. Tikumbukenso kuti laimu si ikuchitika:

- imodzi ndi ntchito manyowa (laimu kuwononga asafe mmenemo);

- imodzi ndi ufa wa phosphate (phosphorous akulowa insoluble);

- pamaso kaloti kubzala tomato, sikwashi, nkhaka, nyemba, udzu winawake, parsley, mbatata (mkulu nkhanambo pa tubers wa).

Ntchito feteleza mchere ndi zofunika chonde ndi mbewu kumene nthaka acidic. Ndichite chiyani kuti muchulukitse zokolola? Kodi kwambiri ndi chovomerezeka fetereza nthaka acid. Kuyambira asafe ndi nitrate: ndi sodium ndi calcium. Musagwiritse ntchito ammonium nitrate ndi urea - iwo acidified nthaka. Ntchito precipitate mankwala. Kuyambira potashi - sulphate potassium phulusa (kuti asungike mu malo owuma).
