Nruab nrab-keeb txheej chiv yog qhov tsis tseem ceeb ntawm kev ua liaj ua teb niaj hnub. Lawv txoj kev siv hluav taws xob tsis tuaj yeem tsuas txhim kho cov av fertility, tab sis kuj txhim kho cov txiaj ntsig thiab cov qoob loo zoo. Cov chiv keeb-chiv muaj cov chiv keeb feem ntau suav nrog calcium, magnesium, thiab leej faj, uas txhua tus ua si ib qho kev ua haujlwm hauv cov nroj tsuag irreplacable hauv cov nroj tsuag.
Cov tshuaj calcium yog ib qho tseem ceeb ntawm cov nroj tsuag ntawm phab ntsa thiab yog qhov tseem ceeb rau kev txhim kho tsob nroj tsis kam thiab kev ntxhov siab tsis kam. Daim ntawv thov ntawm cov calcium fertilizer feem ntau yog xaiv nyob rau hauv thaum ntxov ntawm cov qoob loo thaum ntxov ntawm kev loj hlob qoob, thiab tuaj yeem nqa tawm hauv daim ntawv ntawm cov baal fertilizer lossis suprressing. Thaum ua ntawv thov cov nqaij chiv, sib tov calcium fertilizer nrog cov organic chiv, ces tusyees sib kis nws hauv lub tshav pob thiab khais rau hauv av. Rau saum toj no, dej-soluble calcium chiv yuav xaiv tau, uas tuaj yeem muab tshuaj tsuag, uas tuaj yeem muab txau lossis yaug ntawm nplooj kom nrawm rau cov qoob loo.
Magnesium yog cov tseem ceeb tivthaiv ntawm chlorophyll thiab cuam tshuam ncaj qha cuam tshuam cov photosynthesis ntawm cov nroj tsuag. Daim ntawv thov ntawm cov magnesium fertilitilizer yuav tsum tsom rau kev sib npaug kom tsis txhob muaj ntau dhau lossis tsis muaj daim ntawv thov. Feem ntau, cov chiv magnesium tuaj yeem sib xyaw nrog nitrogen fertilizer thiab phosphorus chiv kom txhim kho cov chiv. Nyob rau tib lub sijhawm, daim ntawv thov tsom ntawm Magnesium fertilitilizer raws li cov khoom sim av tuaj yeem zam tau cov khoom siv pov tseg thiab ua tiav cov txiaj ntsig tau zoo tshaj plaws.
Sulphur yog qhov tseem ceeb ntawm cov amino acids thiab cov protein, thiab muaj cov txiaj ntsig tseem ceeb ntawm kev txhim kho cov ntsiab lus protein thiab qab zoo ntawm cov qoob loo. Sulphur chiv yuav tuaj yeem thov los ntawm sulphur-muaj cov chiv xws li ammonium sulfate thiab potassium sulfate. Thaum ua ntawv thov, kev saib xyuas yuav tsum tau them rau cov qoob loo cov kev thov rau cov neeg tuaj noj tub rog thiab cov neeg Sulphur cov ntsiab lus ntawm cov av kom ntseeg tau tias cov neeg siv cov chiv keeb.
Hauv kev ua haujlwm tiag tiag, kev thov ntawm cov chiv keeb-chiv muaj kev sim ua ke nrog kev kuaj av, cov qoob loo kom tsim kev tshawb fawb ntawm cov phiaj xwm kev ua haujlwm. Los ntawm precise fertilization, tsis tsuas yog tuaj yeem siv tau nyiaj txiag ntawm cov qoob loo tau txhim kho, tab sis kuj tseem muaj kev loj hlob ntawm kev ua liaj ua teb tuaj yeem nce qib.
Mastering daim ntawv thov thiab ua haujlwm cov ntsiab lus ntawm cov chiv keeb-chiv yog qhov tseem ceeb rau kev txhim kho ntawm kev ua liaj ua teb niaj hnub.
