Vim nws tseem ceeb heev txuas ntawm lub hnub thiab lub biosphere: chlorophyll nyob rau hauv cog hlwb nyob rau hauv qhov kev txiav txim ntawm tshav ntuj synthesizes los ntawm dej thiab carbon dioxide nyob rau hauv cov organic teeb meem. daj ntawm cov nroj tsuag yuav muab ib tug ua txhaum ntawm lawv txoj kev kawm nyob rau hauv chlorophyll - ib tug kab mob hu ua Chlorosis. Yog li ntawd, lo lus teb rau cov nqe lus nug ntawm yog vim li cas daj soob seedlings yog heev yooj yim. Tab sis qhov no nyob ib leeg yog tsis txaus - peb yuav tsum tau mus rau lub hauv paus. Thiab ob peb tug ntawm lawv.

Feem ntau ntawm lawv - ib tug ua txhaum ntawm lub hwj chim ntawm lub hauv paus system. Qhov no tshwm sim vim nws puas tsuaj, lub cev los kub (subcooling). Tiam sis yog tias ntxhov kub, Chlorosis muaj feem xyuam rau tag nrho cov nroj tsuag. Thiab yog hais tias, hais tias, cov neeg kho tshuab kev puas tsuaj rau lub hauv paus system tau nyob rau hauv lub tsaws soob seedlings nyob rau hauv lub vaj, tsuas yog tus qis nplooj tig daj. Nyob rau hauv cov ntaub ntawv no, koj yuav tsum tau tos rau rooting seedlings thiab tshiab adventitious keeb kwm - Soob Chlorosis tiv nrog rau lawv tus kheej.

Yuav kom txiav txim qhov ua rau ntawm Chlorosis txaus rau saib ze ze ntawm tus hluas nplooj ntawm cov nroj tsuag. Thiab yog hais tias daj soob seedlings yog nrog cov laus (sab) nplooj yuav tsum tau xav tias raws li ib tug tsis muaj ib tug ntawm cov tseem ceeb tshaj plaws rau soob tshuaj ntsiab.
Feem ntau cov feem ntau Chlorosis soob seedlings qhia nitrogen tsis muaj peev xwm. Nws yog lo lus hais thiab nplooj leeg xiavlus-liab xim, thiab cov nplooj yog me me thoob plaws cov nroj tsuag raws li ib tug tag nrho. Lower nplooj tuag tawm tom qab daj. Yog hais tias seedlings yog zus rau cov muag khoom, koj yuav tsis txawm sim muab nws nyob rau hauv kev ua lag luam: qhia meej ntawm Chlorosis scare ntawm nws cov neeg muas zaub, thiab tsis muaj kev tshab txhais txog ntawm vim li cas daj soob seedlings, tsis pab.

Daj kuj tseem ua poov tshuaj tsis muaj peev xwm, cov txheej txheem no, tiam sis feem ntau nyob deb vim tsub zuj zuj ntawm ammonia nrog nitrogen, nrog los ntawm lub cev qhuav dej ntawm nplooj thiab lawv sib ntswg, kom txog thaum lub tsos ntawm cov cim ntawm cov ntaub so ntswg necrosis.
Lwm yog vim li cas vim li cas lub daj soob seedlings, ib tug zinc tsis muaj peev xwm. Nws pretends yuav tsum tau ntau heev heev thiab me me flecks daj xim rau cov tub ntxhais nplooj. Lawv, dhau lawm, yuav txo me me, yuav ua tau kiag li daj, tej zaum cov upward. Cov ntaub so ntswg necrosis, tsis zoo li poov tshuaj tsis muaj peev xwm nws ua tau nws tus kheej tam sim ntawd nyob rau daim ntawv nto, tab sis extends considerably sai.

Yog hais tias Chlorosis ntawm cov tub ntxhais nplooj ntawm seedlings pib nrog lawv bases, thiab cov xim yog hom twg los ntawm daj-ntsuab los ntawm lub txiv qaub-daj ua yellowish-dawb, cov nroj tsuag teb hlau tsis muaj peev xwm. Nws yog reflected xwb nyob rau hauv cov tub ntxhais nplooj, tsis tau laus. Qhov no zoo ntawm tsis muaj peev xwm yuav tshwm sim nyob rau hauv thaum ntxov ua sawv ntawm loj hlob seedlings, yog hais tias nws yog ib hnub thiab hmo ntuj tseem ceeb tsis txhawb cov ntaub qhwv uas muaj hlau. Ib tug muaj tsuas mus rov pib dua lawv, raws li cov nroj tsuag los rau li qub nyob rau hauv ob peb teev.

Txawm li cas los, micronutrient raug thiab as-ham yog tus yooj yim los kho. Nws yog ib heev lwm tus tshaj plaws thaum cov lus teb rau cov nqe lus nug ntawm yog vim li cas daj soob seedlings, yuav raws li nram no: nws yog Fusarium. Qhov no txaus ntshai fungal kab mob muaj peev xwm ntaus thaum twg muaj hnub nyoog txiv lws suav. Sib ntaus rau nws nyuaj vim hais tias cov kab mob no yog kuaj lig dhau lawm.
