Kev sib raug zoo ntawm cov chlorophyll meter thiab av

Cov kev loj hlob ntawm cov qoob loo yog qhov tshwm sim ntawm kev sib tov ntawm av noo noo thiab nitrogen txheej xwm, thiab nitrogen cov ntsiab lus ntawm nplooj yog ze ze nrog photosynthesis. Cov spad nqi uas qhia txog chlorophyll cov ntsiab lus (nitrogen cov ntsiab lus) ntawm nplooj yog qee yam av noo noo. Ib qho kev qhia txog nitrogen siv efficiency, kev sib piv ntawm cov txheej txheem soj ntsuam chlorophyll nyob rau hauv dej txawv dej thiab nitrogen qhia tau hais tias muaj ntau yam tsim nyog txaus ntawm nitrogen fertilizer nyob rau hauv qee yam av noo noo, thiab nce ntawm fertilizer daim ntawv thov tsis tau txhim kho cov physiological efficiency ntawm qoob loo.

Qhov kev loj hlob chlorophyll kev soj ntsuam muaj kev sib raug zoo nrog qhov nruab nrab chlorophyll spad nqi thiab qoob loo yield. Qhov ua ntu zus pom tau hais tias nyob hauv ntau hom kev ua liaj teb nitrogen, cov chlorophyll thiab cov cheeb tsam ntawm cov nplooj ntsuas ntawm qhov kev ntsuas ntawm ib theem ntawm txoj kev loj hlob tuaj yeem siv coj los qhia rau theem tom ntej. Kev tswj hwm kev ua liaj ua teb ntawm farmland thiab kev siv kev ua haujlwm ntau. Kev siv cov qoob loo ntawm cov qoob loo muaj peev xwm ua kom muaj cov ntsiab lus chlorophyll, thiab ob qho yog linear.

Nyob rau tib lub sij hawm, qhov ntsuas ntawm chlorophyll 'meter' kuj tau pom tias qhov sib txawv ntawm cov chlorophyll cov ntsiab lus (nitrogen cov ntsiab lus) ntawm cov nplooj ntawm peb lub sij hawm sib txawv hauv kev loj hlob tsis yog yooj yim heev, thiab qhov txawv ntawm kev siv dej ntawm cov qoob loo loj. Lub cev ntawm cov qoob loo ntawm cov qoob loo raug txiav txim siab. Cov ntsiab lus nitrogen ntawm cov nplooj tuaj yeem cuam tshuam cov kev siv dej ntawm kev siv lub cev los ntawm kev cuam tshuam cov carbon dioxide assimilation rate ntawm cov qoob loo thiab kev siv tau zoo npaum li cas ntawm hluav taws xob

Qhov nce ntawm nplooj ntoos chlorophyll (nitrogen cov ntsiab lus) muaj cov nyhuv tseem ceeb ntawm kev txhim kho kev siv dej kom zoo. Hauv kev loj hlob ntawm lub cev, cov qoob loo tsuas yog absorbs nitrogen tawm sab nraud. Tom qab cov txiv hmab txiv ntoo yog tsim, qoob loo absorbs nitrogen los ntawm sab nraum. Nyob rau lwm cov tes, lub nitrogen nyob rau hauv lub keeb kwm, stems thiab yoo mus rau lub cev txiv hmab txiv ntoo mus rau compensate rau deficiency ntawm nitrogen uptake. Yog li ntawd, qhov tawm tau tuaj yeem kwv yees raws li cov ntsiab lus nitrogen ntawm nplooj thaum lub sijhawm kev loj hlob.

Cov qoob loo cog qoob loo thiab cov av nitrogen av qeeg yog ze rau cov av noo thiab nitrogen, uas yog qhov kawg ntawm cov dej thiab cov chiv quav hauv qee yam kev mob, thiab cov nplooj ntoos nitrogen yog ib qho ntawm feem ntau yam tseem ceeb ntawm cov qoob loo ntawm nitrogen. . Chlorophyll analyzer muab ib txoj kev yooj yim rau kev txiav txim siab nplooj chlorophyll hauv lub tshav pob. Kev tshawb fawb ntawm kev sib raug zoo ntawm chlorophyll raws li txoj cai thiab qoob loo cov dej muaj sia nyob ntawm qhov tob, thiab nws yog ib qho tseem ceeb ntawm cov tswv yim tseem ceeb los coj cov kev taug qab thiab kev soj ntsuam ntawm chlorophyll los ntawm chlorophyll analyzer los qhia cov dej thiab cov kev tswj fais fab.
