Magnesium nitrate (los yog cov tshuaj no kuj hu ua - magnesium nitrate) yog cov chiv zoo heev rau cov nroj tsuag. Nws yog magnesium nitrate uas yog siv los xyuas kom meej tias cov nroj tsuag tau txais qhov tsim nyog ntawm cov kab mob xws li magnesium, nrog rau nitrogen, uas tsim nyog rau kev loj hlob thiab kev noj qab haus huv ntawm cov nroj tsuag.
tshuaj formula
Cov chiv siv tsis yog magnesium nitrate nkaus xwb, tab sis magnesium nitrate ib 6 dej molecules. Cov tshuaj formula zoo li no: Mg(NO3)2 6H2O. Nws yog cov tshuaj no hu ua magnesium nitrate.
Daim ntawv thov
Magnesium nitrate tov yog siv los ua chiv, vim nws muaj magnesium thiab nitrogen thiaj li tsim nyog rau cov nroj tsuag. Qhov zoo ntawm kev siv cov tshuaj no tshwj xeeb yog tias cov tshuaj tsis muaj cov kab mob tsis zoo, thiab tseem soluble tag nrho hauv dej. Magnesium nitrate kuj tseem siv tau ua ke nrog lwm cov chiv, xws li calcium nitrate. Qhov zoo muaj xws li covtias cov tshuaj no yooj yim txaus siv.
Cov txiaj ntsig rau cov nroj tsuag yog dab tsi
Magnesium nitrate yog cov chiv siv ntau tshaj plaws. Tab sis nws qhov txiaj ntsig yog dab tsi? Nws yog ib nqi sau cia hais tias magnesium yog ib qho tseem ceeb heev kab nyob rau hauv cov nroj tsuag, vim hais tias nws yog ib tug tseem ceeb atom nyob rau hauv chlorophyll. Yog li ntawd nws tseem ceeb heev uas cov nroj tsuag tsis muaj cov khoom no.
Nws yog qhov tsim nyog rau txoj kev loj hlob sai, thiab cov hlwb faib ntau zaus. Tsis tas li ntawd, magnesium tswj cov qib tsim nyog ntawm cov protein thiab cuam tshuam qhov tseeb tias cov nroj tsuag tuaj yeem nqus tau phosphorus, uas tseem tsim nyog rau lawv.
Yog tias cov nroj tsuag muaj magnesium starvation, ces nplooj necrosis yog ua tau, nrog rau me me tawm los. Tab sis qhov no tsis txhais hais tias lawv ib txwm xav tau magnesium. Yog hais tias muaj ntau tshaj ntawm nws, ces qhov no yuav ua rau indigestibility ntawm lwm yam kab, piv txwv li, K thiab Ca.
Yog tias cov nroj tsuag nyob hauv av nrog acidity siab, feem ntau nws yuav ntsib magnesium starvation, vim nyob rau hauv cov xwm txheej zoo li no cov kab mob tsis tuaj yeem nqus tau tag nrho.
Magnesium nitrate yog ib qho zoo tshaj plaws cov tebchaw siv rau hauv paus noj ntawm ntau yam nroj tsuag, zaub, berries thiab txiv hmab txiv ntoo qoob loo. Feem ntau, chiv yog siv nrog drip irrigation. Qhov zoo ntawm txoj kev no yog tias nws tso cai rau kev siv cov chiv nitrogen tsawg.
Daim ntawv thov koob
Ua ntej koj fertilize koj cov nroj tsuag, koj yuav tsum tau ua ib co kev sim kom paub tseeb tias nws tsis ua kom puas ntau. Nws nyob ntawm thaj av ib puag ncig, ntawm thaj chaw thaj chaw ntawm qhov chaw. Tsis tas li ntawd, qhov tsis muaj magnesium tuaj yeem txiav txim siab los ntawm kev sau qoob loo. Yog tias tom qab sau qoob, nws cov nyiaj tau txo qis ntawm 40 mus rau 50%, qhov no yuav qhia tau tias cov nroj tsuag tsis muaj micronutrients.
Y Yog siv foliar pub mis, ces yuav tsum tau sim cov tshuaj magnesium nitrate los ntawm 1 mus rau 4%. Yog hais tias lub hauv paus (uas yog, nws coj mus rau hauv nrog cov dej uas cov nroj tsuag yog watered nrog), ces nws yog tsim nyog hais tias cov concentration yuav tsum tsawg - los ntawm 0.01 mus rau 0.2%.
