Tooj liab, ib txoj kab tseem ceeb rau cov nroj tsuag

1. Cov haujlwm tseem ceeb ntawm tooj liab ntawm tooj liab
Tooj liab koom nrog ntau cov txheej txheem metabolic
Tooj liab yog qhov tseem ceeb rau photosynthesis, kev ua pa, pataben metabolism, thiab phab ntsa cell synthesis.
Tooj liab muaj cov txiaj ntsig ruaj khov rau chlorophyll thiab tuaj yeem tiv thaiv kev rhuav tshem kev rhuav tshem kev puas tsuaj thaum ntxov ntawm chlorophyll;
Koom tes nrog kev tsim cov nitrogen-kho cov hauv paus nodules.
Tooj liab kuj txhawb tau cov txheej txheem thoob tsib.
Tooj liab txhawb nqa cov pa tsa.
Tooj liab ua lub luag haujlwm nyob rau hauv framhiting fungi, kev tawm tsam cov neeg tua tsiaj, sib ntaus sib tua thiab lwm yam kev txom nyem.
Tooj liab tsuas yog nqus tau raws li CU2 + thiab CU +, thiab av organic teeb meem tuaj yeem nce cov kev ua tus tooj liab.
Tooj liab yog cov hlau tso zis hlau rau ntau oxidases
Tooj liab koom nrog kev tsim ntawm oxidases uas tuaj yeem tiv thaiv oxidative kev ntxhov siab, xws li:
1) Superoxide dismutase (cuzn-sod) koom nrog kev sib ntaus sib tua oxygen hom o2-,
2) ascorbic acid oxidase (apx) tuaj yeem oxidize acid los tsim dej thiab dehydrocorbic acid
3) Polyphenol oxidase (miv) tuaj yeem oxidize monophenols rau hauv diphenols thiab tom qab ntawd mus rau hauv quiner. Quinone compounds tuaj yeem polymerize los ua xim av-dub sib xyaw, uas thaum kawg ua daim ntawv humus.
Tooj liab tseem muaj feem koom nrog kev tsim cov enastocyanin enzyme. Plastocyanin yog ib tus neeg tseem ceeb ntawm lub phophocolate saw thiab muaj lub luag haujlwm rau kev hloov khoom siv hluav taws xob. Nws lub xeev oxidation yog xiav thiab nws txo qis ntawm lub xeev yog tsis muaj xim.
2. Cov tsos mob ntawm Copper Deficiency Hauv Nroj Tsuag
Cov av rov hais dua yog qhov tsis tshua yog tooj liab tsis txaus
Thawj cov khoom noj muaj txiaj ntsig uas tshwm sim thaum cog rau cov organic av acidical tsis muaj cai, muaj mob feem ntau hu ua "tus kab mob reclamation." Lub subsoil ntawm cov organic xau nyob rau ntau thaj chaw muaj cov tshuaj tsw qab lossis lwm yam calcareous uas muaj kev cuam tshuam rau kev muaj tooj liab, ua rau tooj liab txaus nyuaj heev. Hauv lwm qhov xwm txheej, av tsis muaj av tsis muaj thoob.
"Tus kab mob rellamation", tseem hu ua "tus kab mob reclamation" uas feem ntau tshwm sim hauv cov nroj tsuag herbace, yog vim tooj liab tsis muaj peev xwm. Nws yog feem ntau pom nyob rau ntawm barley cog hauv cov av tshiab uas cov lus qhia ntawm cov nroj tsuag ntawm cov nroj tsuag, thiab lub pob ntseg yog qhov tsawg, txhua yam uas tshwm sim los ntawm tooj liab tsis muaj peev xwm.
Lub ntsiab tseem ceeb ntawm tooj liab tsis txaus hauv cov nroj tsuag
Tooj liab tsis txaus hauv cov nroj tsuag feem ntau ua manifests li withered saum, luv cov lus qhia, nyias, thiab cov txiv hmab txiv ntoo nyias, thiab cov txiv ntoo tawg. Cov nroj tsuag sib txawv feem ntau qhia cov tsos txawv.
Qhov rhiab heev los tooj liab qhov sib txawv heev ntawm cov qoob loo ntau yam. Cov nroj tsuag rhiab yog feem ntau yog oats, pob kws, pob kws, dos, alfalfa thiab luam yeeb, zaub ntsuab thiab Tao et al. Ntawm lawv, hom qoob mog thiab oats yog qhov taw qhia zoo heev cov qoob loo rau copper tsis muaj peev xwm. Lwm cov qoob loo uas teb tias yuav tooj liab yog hemp, flax, carrace, cov zaub ntsuab, cov zaub ntsuab, kua muag thiab dos.
Nroj tsuag uas tiv thaiv tooj liab tsis txaus suav nrog taum pauv uas muaj peev xwm ua rau tooj taum, taum pauv, cov nyom, cov kua qaub, roj pleev roj thiab ntoo thuv. Rye muaj qhov tshwj xeeb tsim nyog rau cov av tsis txaus. Qee tus neeg tau ua cov kev sim sib piv. Thaum tsis muaj daim ntawv thov tooj liab, cov plaub ua tsis tiav los tsim cov qoob loo, thaum rye grew rasustly.

3. Tooj hauv cov av thiab tooj liab chiv ntawm kev ua lag luam
Tooj liab-muaj cov minerals nyob rau hauv av suav nrog chalcophrite, chalcocite, thiab feem ntau ntawm tus tooj liab tau adsorbed los ntawm av av nplaum hais lossis khi los ntawm cov organic. Hauv cov av uas rov hais dua, tooj liab tsis txaus, tseem hu ua "synlamation syndrome", feem ntau tshwm ua ntej. Cov neeg siv cov chiv feem ntau siv chiv chiv yog gallite (cuso4 · 5to), uas yog tooj liab sulfate pentahydrate, uas muaj cov dej solubility zoo. Feem ntau siv rau kev txau foliar. Chelated trace keeb cov activator muaj tooj liab thiab tuaj yeem siv rau av daim ntawv thov thiab cov quav yeeb txau.
