Thaum nyeem cov ntawv sau rau ntawm pob chiv, tej zaum koj yuav tau hla lo lus "chelated hlau" thiab xav tsis thoob tias nws yog dab tsi. Raws li cov neeg ua teb, peb paub tias cov nroj tsuag xav tau nitrogen, phosphorus, potassium thiab micronutrients, xws li hlau thiab magnesium, kom loj hlob zoo thiab tsim cov paj zoo nkauj lossis txiv hmab txiv ntoo. Tab sis hlau tsuas yog hlau, puas yog? Yog li dab tsi yog chelate hlau? Nyeem ntxiv rau cov lus teb ntawd, thiab cov lus qhia txog thaum twg thiab yuav siv cov hlau chelated li cas.

Chelated Iron yog dab tsi?

Cov tsos mob ntawm cov hlau tsis txaus hauv cov nroj tsuag tuaj yeem suav nrog chlorotic foliage, stunted lossis malformed tshiab kev loj hlob thiab nplooj, paj lossis txiv hmab txiv ntoo poob. Feem ntau, cov tsos mob tsis tshwm sim ntau dua li tsuas yog discoloration ntawm nplooj. Iron deficiency nplooj yuav ntsuab veined nrog ib tug mottled daj xim nyob rau hauv cov nroj tsuag cov ntaub so ntswg ntawm cov leeg. Foliage kuj tuaj yeem tsim cov nplooj nplooj xim av. Yog tias koj muaj nplooj ntoo zoo li no, koj yuav tsum muab cov nroj tsuag ib co hlau.

Qee cov nroj tsuag tuaj yeem ua rau muaj hlau tsis txaus. Qee hom av, xws li av nplaum, chalky, irrigated av ntau dhau los yog cov av uas muaj pH siab, tuaj yeem ua rau cov hlau muaj hlau kaw lossis tsis muaj rau cov nroj tsuag.

Hlau yog hlau ionuas tuaj yeem ua rau oxygen thiab hydroxide. Thaum qhov no tshwm sim, cov hlau tsis muaj txiaj ntsig rau cov nroj tsuag, vim lawv tsis tuaj yeem nqus nws hauv daim ntawv no. Txhawm rau ua kom cov hlau yooj yim rau cov nroj tsuag, chelate yog siv los tiv thaiv cov hlau los ntawm oxidation, tiv thaiv nws los ntawm leaching tawm hauv av thiab khaws cov hlau nyob rau hauv ib daim ntawv uas cov nroj tsuag siv tau.

Yuav ua li cas thiab Thaum twg Yuav Thov Hlau Chelates

Chelators kuj tseem hu ua ferric chelators. Lawv yog cov molecules me me uas khi rau hlau ions los ua micronutrients, xws li hlau, yooj yim dua rau cov nroj tsuag. Lo lus "chelate" los ntawm Latin lo lus "chele," uas txhais tau hais tias lobster claw. Cov chelator molecules qhwv ib ncig ntawm cov hlau ions zoo li lub kaw ntom nti.

Kev siv hlau tsis muaj chelator tuaj yeem nkim sijhawm thiab nyiaj txiag vim tias cov nroj tsuag yuav tsis tuaj yeem nqa hlau txaus ua ntej nws yuav oxidized lossis leached los ntawm cov av. Fe-DTPA, Fe-EDDHA, Fe-EDTA, Fe-EDDHMA thiab Fe-HEDTA yog txhua hom chelated hlau uas koj tuaj yeem pom tau teev nyob rau hauv cov ntawv sau chiv.

Chelated hlau chiv muaj nyob rau hauv spikes, pellets, granules los yog hmoov. Ob daim ntawv tom kawg tuaj yeem siv tau ua dej-soluble chiv lossis foliar sprays. Spikes, qeeb-tso granules thiab dej-soluble chiv yuav tsum tau siv raws li cov nroj tsuag txoj kab drip kom ua tau zoo tshaj plaws. Foliar chelated iron sprays yuav tsum tsis txhob tsuag rau cov nroj tsuag thaum kub, tshav ntuj.
