Cov ntsiab lus kab yog qhov tseem ceeb rau tib neeg, tsiaj txhu lossis nroj tsuag. Calcium deficiency hauv tib neeg thiab tsiaj txhu yuav cuam tshuam rau kev loj hlob ntawm lub cev. Calcium deficiency nyob rau hauv cov nroj tsuag kuj yuav ua rau kev loj hlob lesions. Pub qibcalcium formateyog ib qho calcium-soluble foliar fertilizer nrog kev ua haujlwm siab, uas tuaj yeem txau ncaj qha rau ntawm nplooj foliar, nrog kev nqus siab thiab kev siv tus nqi, tus nqi qis thiab kev ua haujlwm yooj yim.

Tam sim no, nyob rau hauv kev tsim zaub, tib neeg tsuas yog them sai sai rau cov tswv yim ntawm ntau cov ntsiab lus nitrogen, phosphorus thiab poov tshuaj chiv vim muaj kev cuam tshuam ntawm kev ua qoob loo ib txwm muaj, thiab feem ntau tsis quav ntsej cov tshuaj ntxiv ntawm cov ntsiab lus nruab nrab calcium thiab magnesium chiv, ua rau muaj kev cuam tshuam ntawm cov nroj tsuag. physiological calcium deficiency thiab magnesium deficiency hauv zaub. Cov tsos mob hnyav zuj zus txhua xyoo, ua rau poob zoo rau kev tsim zaub. Cov txiaj ntsig ntawm calcium rau cov qoob loo yog deb underestimated los ntawm peb.

Kev ua haujlwm ntawm calcium

1. Calcium tuaj yeem ua kom cov qauv biofilm ruaj khov thiab ua kom muaj kev ncaj ncees ntawm tes

Calcium yog cov khoom noj tseem ceeb rau cov nroj tsuag thiab ib qho tseem ceeb ntawm cov phab ntsa ntawm tes. Calcium-deficiency hlwb nyob rau hauv cov nroj tsuag tsis tuaj yeem faib ib txwm, thiab hauv cov xwm txheej hnyav, qhov kev loj hlob yog necrotic, thiab kab mob ntawm lub cev muaj feem cuam tshuam. Ib puag ncig biofilm ruaj khov tuaj yeem txhim kho kev tiv thaiv ntawm cov qoob loo kom rov qab ua dua. Nyob rau tib lub sijhawm, vim tias calcium tuaj yeem ua rau muaj kev xaiv ntawm cov cell membrane rau kev nqus ntawm cov poov tshuaj, sodium thiab magnesium ions, thiab cov poov tshuaj thiab sodium ions tuaj yeem txhawb kev ruaj ntseg ntawm cov hlwb, yog li txhim kho cov qoob loo retrograde. Txhawm rau muab nws bluntly, calcium tuaj yeem txhim kho qhov kev tiv thaiv retrograde ntawm cov qoob loo.

2. tuaj yeem tiv thaiv kev laus ntxov ntxov

Lub senescence ntawm cov nroj tsuag yog ze ze rau zus tau tej cov ethylene nyob rau hauv lub cev, thiab calcium ions yuav txo tau lub biosynthesis ntawm ethylene los ntawm kev tswj ntawm cell membrane permeability, yog li tiv thaiv ntxov ntxov senescence ntawm cov qoob loo. Yog tias koj tsis xav kom cov qoob loo tuag ntxov, daim ntawv thov ntawm calcium chiv yog qhov tseem ceeb.

3. Stabilize lub cell phab ntsa

Calcium deficiency ua rau lub cell phab ntsa ntawm apples disintegrate, softening ntawm cell phab ntsa thiab cov mesocolloid txheej, thiab ces cov hlwb rupture, ua rau dej plawv thiab lub plawv rot.

4. Calcium kuj muaj cov nyhuv o

Calcium tuaj yeem txhawb nqa cell elongation, uas tseem ua lub luag haujlwm hauv o. Nyob rau tib lub sijhawm, nws tseem tuaj yeem txhawb nqa cov elongation ntawm cov hauv paus hniav, yog li txhawb cov hauv paus hniav.

5. Txuas lub sijhawm cia

Thaum cov ntsiab lus calcium nyob rau hauv cov txiv hmab txiv ntoo siav yog siab, nws tuaj yeem tiv thaiv qhov tshwm sim rotting hauv cov txheej txheem tom qab sau qoob loo, ncua lub sijhawm cia thiab ua kom cov txiv hmab txiv ntoo khaws cia zoo.

Qhov tseeb, yog tias koj nkag siab txog ntau yam khoom noj khoom haus ntawm cov qoob loo kom meej, koj yuav pom tias muaj ntau yam kab mob feem ntau tshwm sim los ntawm kev tsis zoo ntawm cov qoob loo los ntawm kev noj zaub mov tsis zoo. Kev noj zaub mov kom zoo, muaj kab mob tsawg dua thiab tsawg kab.

Tom qab tham txog kev noj zaub mov zoo ntawm calcium, qhov kev poob qis yuav ua rau calcium deficiency li cas?

Thaum tsis muaj calcium, kev loj hlob ntawm cov nroj tsuag yog stunted, thiab cov internodes yog luv, yog li lawv feem ntau luv dua li cov nroj tsuag ib txwm, thiab cov ntaub so ntswg yog mos.

Lub apical buds, lateral buds, cov lus qhia hauv paus thiab lwm yam meristems ntawm cov nroj tsuag uas tsis muaj calcium ua ntej tshwm sim as-ham-deficient, perishable, thiab cov nplooj hluas yog curled thiab deformed. Nplooj nplooj pib tig daj thiab maj mam ua necrotic. kab mob; txiv lws suav, kua txob, txiv lws suav, thiab lwm yam. muaj kab mob plawv; apples muaj iab pox thiab dej plawv kab mob.

Yog li ntawd, calcium supplementation yog ib qho tseem ceeb heev, thiab nws tsis tas yuav tsum tau supplemented tom qab cov txiv hmab txiv ntoo tau loj hlob, tab sis supplemented ua ntej, feem ntau ua ntej paj.

Zoo, txij li calcium muaj txiaj ntsig zoo, nws yuav tsum tau ntxiv li cas?

Ntau cov av nyob rau sab qaum teb yog calcareous av uas nplua nuj nyob rau hauv calcium, tab sis thaum kawg, txhua leej txhua tus pom tias lawv tseem yuav tsis muaj calcium, thiab cov nplooj tshiab tseem tsis muaj calcium. Yuav ua li cas?

Qhov ntawd yog qhov tsis muaj calcium hauv lub cev, uas yog, muaj calcium ntau, tab sis nws tsis muaj txiaj ntsig.

Kev thauj muaj peev xwm ntawm calcium nyob rau hauv xylem feem ntau nyob ntawm qhov kev siv ntawm transpiration, yog li ntawd, cov ntsiab lus calcium nyob rau hauv cov nplooj qub yog feem ntau tshwj xeeb; Txawm li cas los xij, lub transpiration ntawm lub davhlau ya nyob twg buds, lateral buds, thiab cov lus qhia hauv paus ntawm cov nroj tsuag kuj tsis muaj zog, thiab nws yog supplemented los ntawm transpiration. Calcium yuav tsawg dua. Muab hais bluntly, nws tsis muaj zog li Lao Ye, thiab nws nyiag lwm tus tsis tau.

Yog li, txawm tias cov av nplua nuj npaum li cas, foliar spray supplementation tseem yog qhov tseem ceeb. Qhov no yog vim li cas calcium supplementation ntawm nplooj ua haujlwm zoo. Vim tias calcium absorbed los ntawm cov av tsis tuaj yeem ncav cuag cov nplooj tshiab, cov nplooj qub khaws cia rau lawv tus kheej.

Ib tug zoo calcium fertilizer yog inseparable los ntawmcalcium formate,

Calcium formate yog dav siv nyob rau hauv calcium chiv. Nws yog nplua nuj nyob rau hauv me me molecular organic calcium, muaj kev siv siab, nqus sai, thiab tsis yooj yim rau kho los ntawm av; nws muaj peev xwm ua tau raws li qhov nqus ntawm calcium nyob rau hauv cov qoob loo loj hlob lub sij hawm. Muaj txiaj ntsig tiv thaiv kab mob physiological ntawm cov qoob loo tshwm sim los ntawm calcium deficiency.
