Qhov tseem ceeb ntawm chlorophyll 'meter' rau ntsuas nitrogen cov ntsiab lus hauv cov nroj tsuag

Cov ntsiab lus chlorophyll ntsuas ntsuas chlorophyll cov ntsiab lus thiab khaus tawm cov khoom nitrogen cov khoom. Yog li dab tsi yog kev siv cov ntsuas nitrogen cov ntsiab lus? Nitrogen plays lub luag haujlwm tseem ceeb hauv kev loj hlob ntawm cov nroj tsuag. Lub synthesis ntawm ntau muab kev pab cuam nyob rau hauv cov nroj tsuag yog inseparable los ntawm nitrogen. Yog hais tias cov nroj tsuag nitrogen yog tsis txaus, nws yog ib qho yooj yim uas ua rau cov nroj tsuag yuav luv luv, cov nplooj yog daj thiab withered, thiab cov nroj tsuag kev loj hlob yog txo. Nroj tsuag nitrogen cov ntsiab lus tsis txaus, thiab ntau yuav ua rau cov nroj tsuag kom txo tau ntau lawm.

Tam sim no, nyob rau hauv cov txheej txheem ntawm kev ua liaj ua teb qhuav, yuav kom nce qoob loo, muaj ib qho muag tsis pom kev ntawm cov tshuaj chiv nyob hauv cov qoob loo, tshwj xeeb tshaj yog nitrogen fertilizer, uas ua rau tsis txaus ntseeg ntawm kev sib piv, potassium thiab calcium, yuam qoob loo yields los poob. Qhov zoo deteriorates, thiab lub wasted nitrogen fertilizer nkag mus rau hauv ib puag ncig ntuj thiab pollutes cov av thiab dej cov kev pab. Yog li, nws yog ceev kom nrhiav tau nitrogen theem rau cov qoob loo ntawm tus chlorophyll analyzer.

Chlorophyll fluorescence tsis tau sai sai thiab muaj tseeb cuam tshuam photosynthetic yam ntxwv ntawm cov qoob loo. Chlorophyll fluorescence technology yog ib txoj kev zoo tshaj plaws rau kev txiav txim siab ntawm kev txav khoom ntawm cov duab photosynthesis. Nws tau raug siv nyob rau hauv qhov kev ntsuam xyuas ntawm cov nroj tsuag muab kev pab cuam thiab cov teebmeem ntawm lwm yam hauv cov nroj tsuag. Qhov teebmeem ntawm nitrogen thiab phosphorus ntawm chlorophyll fluorescence tsis ntawm Haematococcus tau kawm los ntawm cov ntsiab lus chlorophyll. Cov kev hloov ntawm chlorophyll fluorescence tsis ntawm roj tshuaj yej nrog phosphorus concentration tau sib tham. Lettuce yog nplua nuj nyob rau hauv cov vitamins, proteins, thiab lwm yam, uas yog cov qoob loo ntau. Txawm li cas los xij, txoj kev sib raug zoo ntawm chlorophyll fluorescence tsis thiab nitrogen cov nyom nyob rau hauv cov zaub ntsuab nplooj yau kuj tsis tshua muaj.

Yog li, cov neeg tshawb xyuas siv chlorophyll ntsiab lus ntsuas chlorophyll cov ntsiab lus ntawm lettuce nplooj hauv ntau hom nitrogen, thiab sojntsuam cov kev hloov ntawm chlorophyll cov ntsiab lus nyob rau hauv lettuce nyob rau hauv txawv nitrogen npuas, thiab txawm hloov cov ntsiab lus nitrogen ntawm lettuce, uas muab rau kev siv lettuce nitrogen fertilizer. Tsim nyog lub hauv paus.
