Rau kev loj hlob sai thiab tsim nyog ntawm lub vaj thiab cov qoob loo cog qoob loo, ntau yam micro thiab macro ntsiab yog xav tau. Ntxiv nrog rau nitrogen, phosphorus thiab potassium, cov nroj tsuag yuav tsum tau txais magnesium los ntawm cov av. Nws tsis yooj yim sua kom ua tiav cov txiaj ntsig zoo yam tsis tas siv cov khaub ncaws uas muaj cov tshuaj no. Feem ntau, nws qhov tsis txaus hauv av yog them los ntawm kev siv cov chiv xws li magnesium sulfate (MgSO4).

Role in plant formation

Nrog tsis muaj magnesium nyob rau hauv cov av hauv horticultural, horticultural thiab ua liaj ua teb cov qoob loo, cov txheej txheem ntawm chlorophyll tsim qeeb. Ntawd yog, tsis muaj qhov macroelement, cov txheej txheem ntawm photosynthesis tsuas yog nres hauv cov ntaub so ntswg. Tsis tas li ntawd, magnesium:

  • txhawb kev nqus ntawm phosphorus los ntawm cov nroj tsuag;
  • ua haujlwm ntau dua 300 enzymes hauv cov ntaub so ntswg kab lis kev cai.

Nrog magnesium txaus hauv cov av, cov nroj tsuag sau cov proteins uas lawv xav tau sai dua. Thiab yog li ntawd, lawv cov hlwb pib faib ntau zog. Tsis tas li, qhov macronutrient no txhawb kev tsim cov tshuaj pectin hauv cov ntaub so ntswg ntawm kab lis kev cai thiab txhim kho saj ntawm txiv hmab txiv ntoo.

MgSO4 yog dab tsi

Koj tuaj yeem ntxiv cov khoom khaws cia hauv cov av siv ntau yam chiv (ammoshenite, vermiculite, dunite hmoov, thiab lwm yam). Txawm li cas los xij, feem ntau hnav khaub ncaws saum toj kawg nkaus ntawm pab pawg no tseem yog magnesium sulfate, tus nqi qis heev. Cov khoom no yog dawb huv, dej-soluble crystals nrog ib tug meej saj. Hauv lwm txoj kev, magnesium sulfate kuj hu ua ntsev ntsev. Ntxiv nrog rau kev ua liaj ua teb, nws yog siv rau hauv tshuaj, zaub mov thiab kev lag luam hnyav.

Magnesium sulfate yog tau los ntawm kev sib cuam tshuam ntawm cov tshuaj hauv qab no:

  • sulfuric acid;
  • oxide, carbonate thiab magnesium hydroxide.

Qee zaum nws kuj raug cais tawm ntawm dej hiav txwv lossis los ntawm cov zaub mov kieserite lossis epsomite.

Siv li chiv

Magnesium sulphate yog cov chiv ua kom nrawm, thiab yog li nws yog siv hauv kev ua liaj ua teb hnyav thaum cog qoob loo thiab lwm yam qoob loo loj. Feem ntau, nws raug nquahu kom siv nws ntawm cov av nruab nrab thiab me ntsis acidic. Nws yog nyob rau ntawm cov av uas cov nroj tsuag feem ntau ntsib qhov tsis muaj magnesium.

Ntxiv rau, MgSO4 yog siv:

  • hauv tsev cog khoom;
  • hauv qhib teb zaub cog;
  • intensive meadows.

Cov chiv no siv tau rau hauv ob qho tib si hauv paus thiab nplooj nplooj.

Siv zaub qoob

Hauv cov vaj thiab zaub vaj, magnesium sulfate 7-dej (MgSO4 x 7H2O) feem ntau yog siv los hnav khaub ncaws saum toj kawg nkaus. Cov nroj tsuag vaj xws li qos yaj ywm, cucumbers thiab txiv lws suav ua rau mob hnyav rau qhov tsis muaj cov khoom noj no. Rau kev pub zaub mov, xws li chiv yog qhov zoo tshaj plaws siv rau lub caij nplooj ntoos hlav ib txhij nrog nitrogen thiab phosphorus tus neeg sawv cev. Thaum npaj cov av hauv lub Plaub Hlis, koj yuav tsum ua:

  • rau cov txiv lws suav thiab dib - 7-10 g / m 2 chiv;
  • rau lwm cov qoob loo - 12-15 g/m2.

Magnesium sulfate rau pelargoniums, marigolds, daisies thiab lwm yam ornamental herbaceous horticultural qoob loo yog siv tib yam li zaub.

Nrog rau qhov tsis muaj cov macronutrient hauv av, kev hnav khaub ncaws saum toj kawg nkaus yuav tsum tau ua txhua lub caij. Feem ntau, cov av hauv qab cov nroj tsuag yog fertilized nrog MgSO4 x 7H2O ib zaug txhua peb lub lis piam. Rau kev hnav khaub ncaws hauv paus, magnesium sulfate yog diluted ntawm tus nqi ntawm 25 g ib 10 liv dej, thiab rau nplooj nplooj - 15 g ib 10 liters. Kev noj cov tshuaj rau zaub thiab paj qoob loo yuav tsum yog kwv yees li 1-1.5 litres ib square meter.

Siv rau vaj tsob ntoo

Rau raspberries, currants, gooseberries, bush roses, mock txiv kab ntxwv, lilacs, thiab lwm yam. magnesium sulphate kuj xav tau thawj zaug nyob rau hauv lub caij nplooj ntoos hlav. Nyob rau tib lub sijhawm, kwv yees li 30 g ntawm cov khoom yuav tsum tau siv rau ib square meter ntawm lub voj voog ze-kab. Thaum lub sij hawm lub caij, foliar pub yog feem ntau nqa tawm rau shrubs. Txau cov nroj tsuag nrog kev daws ntawm 15 g ntawm magnesium sulfate thiab 10 liv dej. Tus nqi ntawm cov nyiaj hauv qhov no yuav tsum yog 1.5-2l/m2.

Magnesium sulfate: daim ntawv thov rau txiv hmab txiv ntoo

Kua ntoo, plums, pears thiab apricots yog fertilized nrog magnesium sulfate nyob rau lub Plaub Hlis nyob rau hauv tus nqi ntawm 30-35 g ib square meter ntawm lub cev lub voj voog. Thaum lub sij hawm lub caij, cov txiv hmab txiv ntoo qis, zoo li shrubs, yog pub los ntawm txau lub crown. Qub txiv apples thiab pear ntoo yog yooj yim dua, ntawm chav kawm, rau fertilize ntawm lub hauv paus. Hauv thawj kis, kev hnav khaub ncaws sab saum toj yog siv rau ntawm tus nqi ntawm 2-3 litres ib tsob ntoo, hauv qhov thib ob - 5-10 litres. Qhov tseeb, kev daws nws tus kheej yog npaj rau hauv kev faib ua feem ntawm 15-25 g ntawm cov khoom ib 10 liv dej.

Kev kho mob

Qhov looser cov av ntawm qhov chaw thiab qis dua nws cov pH, qhov tsawg magnesium nws muaj. Yog li, xuab zeb thiab xuab zeb loamy soddy-podzolic xau tsis zoo nyob rau hauv cov macroelement no. Cov tswv ntawm cov av nrog xws li av yuav tsum tau siv magnesium sulfate thaum lub caij nplooj zeeg ua ib qho kev hnav khaub ncaws saum toj kawg nkaus. Lub sijhawm no ntawm lub xyoo, chiv yog thov rau kev khawb ntawm tus nqi ntawm 50-100 g ib square meter.

Yuav kom paub meej tias pes tsawg magnesium sulfate xav tau hauv thaj chaw tshwj xeeb no, koj tuaj yeem xaj cov av muaj pes tsawg leeg kawm ntawm chav kuaj tshwj xeeb.

Yuav ua li cas txiav txim siab tsis muaj magnesium hauv av

Cov kev tshawb fawb hauv chaw soj nstuam pab txhawm rau txiav txim siab qhov tseeb ntawm cov chiv, suav nrog xws li magnesium sulfate. Txawm li cas los xij, lawv tsis pheej yig niaj hnub no. Yog li ntawd, ntau gardenersnyiam los txiav txim qhov tsis muaj ib yam khoom hauv av raws li lub xeev ntawm cov qoob loo lawv tus kheej.

Tsis muaj magnesium nyob rau hauv kev cog qoob loo ntawm vaj thiab horticultural nroj tsuag yog tshwm sim feem ntau nyob rau hauv tsis zoo hloov nyob rau hauv lub xeev ntawm nplooj nplooj. Nws yog tsim nyog los qhia MgSO4 rau hauv av yog:

  • Fabrics ntawm cov npoo thiab ze ntawm cov leeg ntawm cov nplooj ntawm cov qoob loo tau txais cov xim daj, liab lossis ntshav;
  • daim hlau yog wrinkled heev thiab ua domed vim yog khoov ntawm cov lus qhia nce.

Nws feem ntau tshwm sim tias qee cov nplooj ntawm cov nroj tsuag vim tsis muaj MgSO4 txawm tias tuag tag. Cov cim qhia ntawm magnesium starvation nyob rau hauv lub vaj thiab horticultural qoob loo ib txwm pib tshwm los ntawm hauv qab. Cov nplooj saum toj kawg nkaus hloov lawv cov xim kawg. Hauv cov zaub qhwv, tsis muaj magnesium ua rau marbling ntawm cov ntaub so ntswg.

Ntxiv rau qhov kev hloov pauv tsis zoo ntawm cov nplooj, qhov tsis muaj cov tshuaj no hauv cov av tuaj yeem ua rau cov txiv hmab txiv ntoo tsis zoo thiab, vim li ntawd, cov qoob loo poob qis.

Tus nqi magnesium sulfate ntau npaum li cas

Cov khaub ncaws saum toj kawg nkaus no tau txais nws qhov kev faib tawm tsis yog vim qhov ua tau zoo thiab nrawm ntawm kev ua haujlwm. Tus nqi qis heev kuj piav qhia qhov nrov ntawm cov chiv xws li magnesium sulfate. Tus nqi rau MgSO4 x 7H2O variant ntawm tsuas yog 100-120 rubles. rau ib pob txheem (1 kg). Ordinary magnesium sulfate raug nqi 40-50 rubles / kg, nyob ntawm cov chaw tsim khoom thiab cov chaw muag khoom.
