Yog vim li cas rau cov neeg pluag sau - acidic av. Yuav ua li cas rau lub fertility ntawm cov av?

Ib qho tseem ceeb qhia ntawm fertility ntawm cov av - nws acidity. Quantitatively, nws yog qhia los ntawm pH - pH tus nqi (ib qho kev ntsuas ntawm kev ua si ntawm hydrogen ions). Av acidity nrog pH qhov tseem ceeb nyob rau hauv ntau ntawm 6.1 rau 7.0 - nruab nrab, nws yog ntau paaj rau ib tug ntau yam ntawm cov nroj tsuag, txij thaum xws tej yam kev mob uas muaj nyob rau lawv pab minerals. Zoo tej yam kev mob rau cov nroj tsuag tsim cov av nyob rau hauv uas lub acidity yog nyob ze rau nruab nrab (pH tsawg tshaj li 6 tab sis siab tshaj 5.5). Alkaline earths (pH siab tshaj 7.1), zoo heev txo tau ntawm tsob nroj kev noj haus hais xws li hlau, poov tshuaj, tooj liab, phosphorus, zinc, magnesium, thiab boron. Nyob rau hauv ib tug alkaline ib puag ncig nyob rau hauv lub nroj tsuag nyob rau hauv ntev li ntawm nqi ntawm molybdenum nws los, thiab nws cheeb lawv txoj kev loj hlob. Raws li cov alkalinity thiab acidity cuam tshuam qhov zoo tshaj ntawm cov av. Nws deteriorates filtering thiab breathability. av acidification yog ib tug pH tsawg tshaj li 5.5. Yog hais tias lub pH nqi yog 5.5, tab sis ntau tshaj 5.1, cov av me ntsis acid; mob me av yog nyob rau ntawm ib pH nyob rau hauv ntau 5.0 - 4.6; xav - thaum pH 4.5 - 4.1, thiab heev xav - pH tsawg tshaj li 4.0. Cov kev loj hlob ntawm lub hauv paus system thiab cov nroj tsuag raws li ib tug tag nrho yog slowing down, tawm los txo acidic av. Yuav ua li cas, vim hais tias cov acidic ib puag ncig thiab dejnum rau pab av kab mob, cua nab. Nyob rau rhizomes pulses tsis noog nyob rau hauv cov av nitrogen acidic av. acidic av qauv yog lawm. Heev hinders nkag tau mus rau cov nroj tsuag av minerals: phosphorus, poov tshuaj, magnesium thiab poov hlau - tab sis nyob rau tib lub sij hawm tsub kom txaus nyob rau ntawd radionuclides, txhuas ions, manganese, hlau, hnyav hlau acidic av.

Yuav ua li cas los mus txiav txim lub acidity ntawm cov av?

Lub acidity ntawm cov av yuav tsum tau txiav txim nws tus kheej, tsis muaj resorting mus rau lub agrochemical laboratory. Yuav kom meej seb puas muaj tus pH ntawm cov av, siv ib tug txheej ntawm litmus ntawv. Muaj yog ib tug yooj yim kev. Lub lactic tus me nyuam raj mis nrog graduations sau mus rau theem ntawm lub thib ob sawb sieved av, txhaws nws nrog dej ua ntej mus rau lub thib tsib division thiab ncuav 1/2 me nyuam diav ntawm cwj mem av dawb hmoov. Thiab mam li rub rau lub caj dab ntawm cov roj hmab txiv mis, pre-yob nws nruj nreem. Ntawv xov xwm los qhwv lub raj mis thiab co rau tsib feeb. Los ntawm cov tshuaj tiv thaiv nrog chalk av acids yuav tso cov pa roj carbon dioxide, tsim siab. Yog hais tias lub acidity ntawm cov av yog tsis muaj zog, ces cov lub txiv mis yuav rov qab me ntsis, thiab nws inflates nrog muaj zog acidity. Muaj nrig txog kev pom kev, uas yog tsawg yog. Nroj nyob rau hauv acidic xau qhia rau peb hais txog cov qib ntawm acidity. Nyob rau hauv me ntsis acidic xau hais xws taw qhia cov nroj tsuag zoo li couch nyom, dandelion, dawb clover, pob caus-nyom, ntoo sorrel, mayweed, Ranunculus repens. Nyob rau ib tug me nce Viola tricolor, clover plowed teb, plantain, qus sorrel, qus mint. Txaus acidic av them nrog horsetail, paj rwb nyom, miv lub paw, schavelkom me me. Yog hais tias lub caij nplooj ntoos hlav ntawm cov av ntev dries, thiab ces dries sai sai thiab yuav crusty, qhov no qhia hais tias muaj yog acidic av.

Yuav ua li cas rau neutralize cov av

Nws thiaj li acidity ntawm lub txiv qaub av. Yuav kom qhov no kawg, tsim hydrated txiv qaub, uas yog ua nyob rau hauv lub caij nplooj ntoos hlav thiab lub caij nplooj zeeg ua ntej plowing. Txiv qaub yuav tsum tau hloov nrog crushed cwj mem av dawb, ntoo tshauv, marl. Ua ntej liming xyuas nyob rau hauv phau ntawv nyob rau hauv siv tau thiab txaus koob tshuaj ua ib yam khoom uas nyob rau hauv tus txheej txheem ntawm Liming lawv tsis txhob ua acidic alkaline xau. Nws yuav tsum tau muab sau tseg hais tias txiv qaub yog tsis nqa tawm:

- ib txhij nrog rau daim ntawv thov ntawm quav (txiv qaub puas nitrogen nyob rau ntawd);

- ib txhij nrog lub phosphate hmoov (phosphorus nkag insoluble);

- ua ntej cog carrots, txiv lws suav, taub, dib, taum, kav zaub, zaub txhwb qaib, qos yaj ywm (high kiav txhab nyob rau hauv lub tubers).

Daim ntawv thov ntawm mineral chiv yog tsim nyog rau fertility thiab cov qoob loo nyob qhov twg cov av yog acidic. Yuav ua li cas kuv yuav tsum tau ua li cas rau kom loo? Yuav ua li cas yog qhov zoo tshaj thiab tau fertilizer rau acid av. Los ntawm nitrogen yog nitrate: sodium thiab calcium. Tsis txhob siv ammonium nitrate thiab urea - lawv acidified av. Siv phosphate precipitate. Los ntawm potash - poov tshuaj sulfate, ntoo tshauv (nws yuav tsum tau khaws cia nyob rau hauv ib tug qhuav ib puag ncig).
