Nitrogen yog ib qho tseem ceeb ntawm cov organic tebchaw hauv cov nroj tsuag, xws li cov proteins, nucleic acids, thiab chlorophyll, ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm tsob ntoo. Siv cov chiv nitrogen ncaj qha ntxiv cov khoom siv nitrogen hauv cov av, ua tau raws li cov nroj tsuag xav tau nitrogen thiab txhawb nqa cov nroj tsuag kev loj hlob thiab kev loj hlob. Tshwj xeeb, kev ua haujlwm ntawm nitrogen chiv yog qhov tseem ceeb hauv cov hauv qab no:
Txhawb Kev Loj Hlob Loj: Nitrogen fertilizer ho txhawb kev loj hlob ntawm cov nroj tsuag stems thiab nplooj, ua rau lush, tsaus ntsuab nplooj thiab nce photosynthetic efficiency. Qhov no ua rau muaj kev nce ntxiv ntawm cov khoom siv photosynthetic, muab cov khoom siv txaus rau kev loj hlob ntawm kev loj hlob.
Txhim kho cov nroj tsuag kev nyuaj siab: Kev siv cov chiv nitrogen tsim nyog tuaj yeem txhim kho cov nroj tsuag kev ntxhov siab, xws li kev tiv thaiv drought, txias tsis kam, thiab kab mob. Qhov no yog vim hais tias nitrogen koom nyob rau hauv ntau yam physiological thiab biochemical txheej txheem nyob rau hauv cov nroj tsuag, regulating dej tshuav nyiaj li cas thiab osmotic siab, thiab kev txhim kho cov nroj tsuag adaptability rau tej yam tsis zoo.
Txhim kho Agricultural Product Quality: Rational application of nitrogen fertilizer tuaj yeem txhim kho cov khoom ua liaj ua teb zoo, xws li nce cov ntsiab lus protein ntawm cov qoob loo, cov roj cov qoob loo, thiab cov vitamin ntsiab lus ntawm txiv hmab txiv ntoo thiab zaub. Qhov no yog qhov tseem ceeb heev rau kev txhim kho kev lag luam tus nqi ntawm cov khoom ua liaj ua teb thiab txhim kho cov neeg siv khoom txaus siab.
