Dab tsi ntawm cov av yuav muab qhov txhim khu kev qha. Feem 2

Nyeem ntu yav dhau los hauv tsab xov xwm: Cov av zoo li cas yuav muab qoob loo uas ntseeg siab tau. Feem 1

Nrog kom muaj acidity ntau ntxiv, qhov kev loj hlob ntawm cov hauv paus hniav poob qis, lawv cov ceg nres, tus naj npawb ntawm cov hauv paus plaub hau tsawg zuj zus, cov hauv paus cag ntom ntom, ua ntau ntxhib thiab ua me ntsis nplua, qhov ntws ntawm phosphorus rau hauv cov nroj tsuag cag yog inhibited. Nroj tsuag cog hauv acidic cov av ntau dua cuam tshuam los ntawm kab tsuag thiab kab mob, thiab cov khoom uas tau khaws cia tsis tshua khaws cia.

Txhawm rau tsim cov koob tshuaj ntawm txiv qaub, cov acidity ntawm cov av tau txiav txim siab, coj mus rau hauv tus account lub txheeb raws roj ntsha ntawm cov qoob loo, kev siv tshuaj tua kab mob thiab lwm yam. Txhawm rau txo cov acidity ntawm cov av, nws yog limed los ntawm kev ntxiv ntoo tshauv, dolomite hmoov uas muaj calcium thiab magnesium, nrog rau cov kab nrib pleb thiab lub plhaub pob zeb, hydrated txiv qaub.

Ntawm ntseeg tau acidic xau, liming yog nqa tawm maj, txij li thaum hloov hauv acidity siv sijhawm. Yog li ntawd, lub caij nplooj zeeg, lub caij ntuj no lossis lub caij nplooj ntoo hlav ntxov yog lub caij zoo tshaj plaws rau kev liming. Cov lus qhia ntawm cov nplais slaked yuav ua tau zoo nyob rau hauv 2-3 lub hlis, tab sis ntxiv chalk lossis av limestone yuav muab cov txiaj ntsig tsuas yog tom qab rau lub hlis.

Txiv qaub chiv ua ntawv thov rau cov av ntawm thaj tsam ib zaug txhua 4-5 xyoos. Ntawm cov av ntom, cov kua qaub pleev rau tom qab 3-4 xyoos, thiab hauv cov av hnyav - tom qab 5-6 xyoos. Lub plua tshauv plua plav ntawm cov pob zeb lim, qhov muaj zog nws cov nyhuv. Kev lim dej hauv av, dolomite hmoov, tuff thiab txhua hom ntoo tshauv tuaj yeem siv rau cov av nrog quav tsiaj. Ua ntej, txiv qaub chiv tau kis tusyees dhau ntawm qhov chaw, thiab tom qab ntawd ua cov quav. Cov av tau muab khawb kom siv tib hnub ntawd.

Hlav cov kua qaub, cov hmoov av ntawm cov pob zeb, cov pob zeb hauv av ua kom sov slag, shale tshauv, thiab lwm yam kuj yog cov ntaub ntawv zoo rau txo cov av acidity. Tab sis cov ntaub ntawv no muaj cov caustic calcium sib xyaw, uas tsis tuaj yeem siv ib txhij nrog quav tsiaj, vim tias qhov ntau ntawm nitrogen tau ploj ntawm cov quav. Thaum ua ntawv thov manure nyob rau lub caij nplooj zeeg, cov khoom siv txiv qaub yog siv rau lub caij nplooj ntoo hlav thiab sab nraud. Ntxiv rau, ntau npaum li cas ntawm cov ntawv thov hloov pauv nyob ntawm seb hom av. Yog li, kev hloov kho acidity tsis tuaj yeem xav kom raug. Cov lus hauv qab no qhia cov koob tshuaj ntawm cov ntaub ntawv yuav tsum tau txo qhov acidity ntawm av los ntawm 1 pH nce qhov ntsuas (ntxiv rau 1 square meter).

Koob tshuaj ntawm cov ntaub ntawv txiv qaub

Av hom	Lim av (g / sq.m)	Slaked txiv qaub (g / sq.m)
Xuab zeb	220	160
Lo ntsiab	300 tawm	230
Alumina	440	310

Cov koob av ntawm chalk thaum lub sijhawm liming kuj tseem sib txawv thiab vam khom cov qoob loo zus, cov khoom siv cov kua qaub uas siv, cov degree ntawm acidity, thiab cov khoom siv ntawm cov av. Hauv qab no yog cov lus qhia uas qhia cov koob av ntawm av dawb nyob ntawm seb hom av.

Caum Chalk

Cov Av	Kev txhaj tshuaj ntawm chalk, kg / m², ntawm pH qhov tseem ceeb
	Txog li 4.5	4.6	4.8	5.0	5.2	5.4-5.5
Ntxub	0.30	0.25	0.20	0.15	0.10	0.10

Cov koob tshuaj ntawm xaum muab hauv qhov rooj feem ntau hu ua tag nrho cov koob tshuaj. Lawv tau tsim los txo cov acidity ntawm cov av xau nrog qhov ib txwm noo noo rau ib pH ntawm 5.6-6.0, i.e. rau ib theem uas zoo rau ntau cov qoob loo. Ntawm cov av xau, ntau heev noo noo, qhov koob tshuaj ntawm cov khoom siv txiv qaub yuav tsum tau nce 0.1-0.15 kg / m² ntau dua ntawm cov tau muab rau hauv cov lus, thiab rau hnyav dua - los ntawm 0.15-0.20 kg / m². Liming ntawm peat-boggy xau nws muaj nws tus yam ntxwv. Cov acidity muaj txiaj ntsig tsim rau cov xau nrog cov organic cov ntsiab lus tsawg yog qhov tsis tsim nyog rau peat xau. Qhov xav tau ntawm kev liming ntawm cov av yog suav tias yog qhov muaj zog ntawm pH tsawg dua 3.5, nruab nrab - pH 3.5-4.2, tsis muaj zog - pH 4.2-4.8 thiab tsis tuaj ntawm pH 4.8. Yog tias muaj qhov xav tau muaj zog, koj yuav tsum thov 300 g / m², nruab nrab - 200 g / m² thiab tsis muaj zog - 100 g / m² kua qaub.

Yog tias ntoo tshauv yog tswvcuab rau hauv av, spruce tau noj ob zaug ntau dua li cov txiv qaub lossis xaum, thiab birch thiab ntoo thuv - ib thiab ib nrab zaug. Cov hmoov av hluav taws kub tau siv tau rau ntawm txhua qhov av thiab hauv qab tej nroj tsuag. Tshauv tuaj yeem siv ua chiv loj hauv lub caij nplooj zeeg ua ntej plowing lossis rau khawb, lossis rau lub caij nplooj ntoo hlav hauv kev npaj rau lub caij cog, nrog rau cov av hauv cov av hauv cog qhov. Thaum qhia rau hauv cog qhov, nws yog sib xyaw nrog humus, peat thiab manure.

Txo cov kua qaub acidic ua kom zoo dua ntawm cov chiv ntsuab (chiv ntsuab), tshwj xeeb tshaj yog thaum lawv suav nrog tib lub sijhawm. Txawm li cas los xij, ntxiv cov txiv qaub tsis muaj qhov xav tau tshwj xeeb, tshwj xeeb tshaj yog ntawm cov av xuab zeb, yuav tsum tsis txhob nqa mus. Qhov no ua rau ntau cov microelements nkag tsis tau rau cov nroj tsuag (lawv yaj zoo nyob rau hauv cov acids thiab nag lossis daus nyob rau hauv ib puag ncig alkaline). Nyob rau tib lub sijhawm, cov av qeeg qhuav tshwm hauv cov av. Cov kev ntsuas hauv qab no ua rau muaj qee qhov nce hauv acidity: kev qhia ntawm cov av chiv, chiv, peat thiab nplooj lwg hauv av ntawm cov av sau qoob. Hauv qab no yog cov lus qhia uas qhia qhov nce ntawm acidity los ntawm 1pH (ntxiv rau 1 m²).

Acidity nce rooj

Ammonium sulfate	70 g
Grey xim	70 g
Peat	1.5KG
Nplooj Lwg	9,25 kg
Chiv	3 kg

Thaum lub neej, pH qib hauv cov substrate hloov. Cov nroj tsuag lawv tus kheej pauv pH kom txog rau qee yam los ntawm kev sib nkag hauv paus. Kev siv dej nrog cov dej sib zog ua kom qis qhov acidity, thiab dej muag muag nce ntxiv. Ntxiv rau, cov chiv ua rau muaj pH. Calcium nitrate nce pH, thiab ammonium sulfate, potassium chloride, thiab urea acidify qhov nruab nrab nrog kev siv txhua xyoo, txo pH.

Nrog rau liming, lub teeb xoob xoob dhau los ua kev sib xyaw ntau dua, thiab cov xoob xoob hnyav, lawv cov dej permeability nce, thiab kev ua kom zoo dua qub. Liming ua kom cov kev ua haujlwm ntawm cov kab mob me me uas ncaj qha rau cov pa nitrogen los ntawm huab cua lossis los ntawm nodules ntawm cov hauv paus hniav ntawm cov nroj tsuag, thiab cov kab mob me me uas ua rau lub cev qhuav pias, yog li txhim kho cov khoom noj khoom noj khoom haus.

Nroj tsuag kho av acidity txawv. Ntawm lub hauv paus no, lawv tau muab faib ua plaub pawg:

1. Cov nroj tsuag uas tsis tuaj yeem zam lub siab acidity thiab feem ntau muaj peev xwm teb rau cov av xaim

(beets, zaub qhwv, dos, qij, zaub kav, zaub ntsuab, zaub ntsuab, txiv duaj, txiv ntoo, paj txiv ntoo, paj txiv ntoo, levkoy, paj tawg, chrysanthemums, ageratum, kochia, aster), thiab lwm yam).

2. Nroj tsuag uas xav tau cov kua qaub me ntsis thiab ze rau qhov nruab nrab ntawm cov av tshuaj tiv thaiv uas teb zoo rau liming

(zaub paj, kohlrabi zaub qhwv, zaub xas lav, leeks, dib, rutabagus, txiv moj coos, tsob ntoo txiv ntoo, txiv pos nphuab, asparagus, amaryllis, alternantera, liab sawv, noob taum), kev ua lag luam, tswb, pelargonium, primrose, radish, zucchini, Zaub pob qe thiab nplooj zaub qhwv, turnip, txaij, chokeberry, chicory, apricot, txiv quav ntswv nyoos, lilacs, chrysanthemums, crocuses).

3. Nroj tsuag uas tsis zam cov calcium uas ntau dhau, nyob rau hauv uas tsuas yog muaj cov kua qaub av ntau heev thiab muaj pes tsawg yuav tsum tau siv cov kua qaub qis dua

(qos yaj ywm, carrots, zaub txhwb qaib, radish, txiv lws suav, radishes, gooseberries, raspberries, azalea, calla lilies, monstera, fern, acroclinum, paj noob hlis, dib liab, pob kws, panicle hydrangea, cherry, kua ntoo).

4. Cov nroj tsuag uas tsis muaj zog txawm tias yuav ua rau muaj acidity ntau ntawm cov av, tsis muaj zog tiv thaiv liming

(sorrel, lupine, hydrangea, seradella, Japanese maple, loj-loj heev magnolia, Japanese andromeda, Japanese skimmia, Erica, qee hom paj laum, horsetails, cranberries, cloudberries, Heather, rhododendrons).
