Qhov sib txawv tseem ceeb ntawm chlorosis thiab necrosis yog tias chlorosis yog daj ntawm cov ntaub so ntswg los ntawm qhov txo qis ntawm chlorophyll, thaum necrosis yog kev tuag ntawm cov nroj tsuag lossis cov ntaub so ntswg.
Nroj tsuag qhia cov tsos mob sib txawv vim muaj kab mob, raug mob lossis tsis muaj zaub mov txaus. Qee cov tsos mob muaj xws li chlorosis, necrosis, wilting, mosaic thiab mottle, thiab dej ntub dej. Chlorosis yog cov tsos ntawm daj me ntsis ntawm nplooj. Nws tshwm sim vim tsis muaj chlorophylls. Nyob rau hauv sib piv, necrosis yog cov tsos ntawm xim av me ntsis ntawm nplooj vim tuag ntawm cov nroj tsuag hlwb los yog cov ntaub so ntswg.
YChlorosis yog dab tsi?
Chlorosis yog hais txog yellowing ntawm cov nroj tsuag, feem ntau nplooj thiab cov leeg. Cov pob daj tshwm rau ntawm nplooj, muab cov qauv mosaic. Yellowing tshwm sim vim tsis txaus ntawm chlorophylls. Chlorophyll ntau lawm tuaj yeem txo qis vim muaj ntau yam laj thawj. Ib qho ntawm cov laj thawj tseem ceeb yog cov khoom noj tsis txaus. Hlau yog ib qho tseem ceeb hauv chlorophyll. Yog li, hlau deficiency yog ib qho tseem ceeb ua rau chlorosis. Tsis tas li ntawd, chlorosis tuaj yeem tshwm sim los ntawm cov kab mob, tshuaj tua kab mob, cov dej tsis zoo, cov hauv paus hniav puas, siab alkalinity, compacted av, thiab lwm yam. Txawm li cas los xij, cov laj thawj ntawm chlorosis yuav txawv ntawm cov nroj tsuag mus rau hom. Piv txwv li, qee cov nroj tsuag loj hlob zoo hauv cov av alkaline, tab sis lawv kuj tuaj yeem pom chlorosis vim qee qhov laj thawj.
Daim duab 01: Chlorosis
Chlorosis tuaj yeem kov yeej los ntawm kev ntxiv cov nroj tsuag nrog cov khoom noj txaus los ntawm kev fertilization. Ntxiv mus, kuaj xyuas qhov laj thawj tshwj xeeb rau chlorosis thiab kho nws raws li kev daws teeb meem zoo tshaj plaws rau chlorosis.
Necrosis yog dab tsi?
Nyob hauv cov nroj tsuag, necrosis hais txog kev tuag ntawm cov nroj tsuag lossis cov ntaub so ntswg. Necrosis tshwm sim vim raug mob lossis kab mob. Tsis tas li ntawd, necrosis tshwm sim los ntawm cov khoom noj tsis txaus. Cov cheeb tsam necrotic tshwm li xim av me ntsis. Necrosis tuaj yeem tshwm sim ntawm nplooj, stems, keeb kwm, nplooj nplooj, cov leeg, thiab lwm yam. Tsis zoo li chlorosis, necrosis yog irreversible.
Daim duab 02: Necrosis
Cov kab mob kis feem ntau ua rau necrosis hauv cov nroj tsuag txij li cov kab mob siv cov nroj tsuag rov ua dua, thiab lawv feem ntau tawm los ntawm lysing tus tswv tsev cell. Tobacco necrosis tus kab mob cuam tshuam rau cov nroj tsuag luam yeeb ua rau necrosis. Ib yam li ntawd, Soybean vein necrosis virus cuam tshuam rau vascular system, thaum tus kab mob cymbidium mosaic cuam tshuam rau orchid paj. Cov kab mob thiab cov fungi kuj ua rau necrosis hauv cov nroj tsuag. Qee cov kab mob degrade cell phab ntsa ntawm cov nroj tsuag, ua rau cell tuag thiab necrosis. Qee cov fungi tawm tsam cov kab mob vascular ntawm cov nroj tsuag thiab ua rau cov kab mob sib txawv xws li anthracnose uas ua rau necrosis hauv cov nroj tsuag.
Dab tsi yog qhov zoo sib xws ntawm Chlorosis thiab Necrosis?
- Chlorosis thiab necrosis yog ob hom kev mob tshwm sim los ntawm cov nroj tsuag.
- Ib qho ntawm cov laj thawj tseem ceeb rau chlorosis thiab necrosis yog cov khoom noj tsis txaus.
- Tsis tas li, ob qho tib si tuaj yeem tshwm sim los ntawm kev kis tus kabmob.
Qhov txawv ntawm Chlorosis thiab Necrosis yog dab tsi?
Chlorosis yog hais txog yellowing ntawm ntsuab xim nroj tsuag, thaum necrosis hais txog kev tuag ntawm cov nroj tsuag thiab cov ntaub so ntswg. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm chlorosis thiab necrosis. Chlorosis tshwm li daj me ntsis, thaum necrosis tshwm li xim av lossis xim dub los yog thaj chaw. Yog li ntawd, lwm qhov sib txawv ntawm chlorosis thiab necrosis yog lawv thim rov qab; chlorosis hnyav tsis tuaj yeem thim rov qab. Tab sis, yog tias pom ntxov, nws yog thim rov qab. Txawm li cas los xij, necrosis tsis thim rov qab.
Summary – Chlorosis vs Necrosis
Chlorosis thiab necrosis yog ob yam tsos mob pom hauv cov nroj tsuag. Chlorosis yog yellowing ntawm nplooj cov ntaub so ntswg vim tsis muaj chlorophyll, thaum necrosis yog kev tuag ntawm cov nroj tsuag los yog cov ntaub so ntswg. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm chlorosis thiab necrosis. Chlorosis tshwm li daj me ntsis, thaum necrosis tshwm xim xim av lossis xim dub ntawm nplooj.
