Koj tuaj yeem nce cov txiaj ntsig yog tias koj siv zinc sulfate. Qhov no yog ib tug universal fertilizer uas yog haum rau paj, txiv hmab txiv ntoo, zaub thiab txiv hmab txiv ntoo qoob loo. Zinc yog qhov tseem ceeb rau cov nroj tsuag kom loj hlob thiab loj hlob. Nws tseem yuav yog qhov tseem ceeb thaum lub sij hawm fruiting.

Vim li cas cov nroj tsuag xav tau zinc?

Txoj kev xav tau cov txiaj ntsig zoo sib txawv ntawm cov qoob loo mus rau qoob loo. Tab sis lawv manifestations ntawm deficiency yog zoo sib xws. Nrog rau qhov tsis muaj zinc, cov nroj tsuag yuav muaj nplooj me me. Cov txiv hmab txiv ntoo ntawm lawv tsis tshua tsim, lawv yuav tsis sib xws.

Rau qhov muaj peev xwm ntawm zinc rau cov nroj tsuag hauv av, cov kab no yuav tsum nyob rau hauv ib qho concentration ntawm 0.5 txog 0.25 mg / kg. Nyob rau tib lub sijhawm, nws tuaj yeem nkag mus rau hauv cov nroj tsuag kab lis kev cai los ntawm cov ntaub ntawv dej-soluble. Tab sis ntawm cov av calcareous, nws xyaum tsis yaj. Vim li no, theem ntawm nws nkag mus rau hauv cov nroj tsuag txo. Qhov muaj zinc kuj tseem deteriorating thaum siv phosphate chiv rau hauv av.

Qhov tsis txaus ntseeg tshaj plaws ntawm cov kab no yog pom ntawm cov txiv apples, txiv hmab txiv ntoo, pears. Nws kuj tseem pom muaj nyob hauv cov tsos ntawm citrus txiv hmab txiv ntoo, cereals thiab qee hom zaub qoob loo. Koj tuaj yeem hloov qhov xwm txheej yog tias koj siv zinc sulfate. Daim ntawv thovcov chiv no yuav tsum tau ua raws li cov qauv tsim. Nov yog tib txoj hauv kev los txhim kho cov qoob loo thiab nce lawv cov qoob loo.

Txoj cai siv chiv

Rau kev txhim kho cov nplej, txiv hmab txiv ntoo, zaub thiab paj qoob loo, cov neeg ua liaj ua teb paub txog kev siv zinc sulfate. Kev daws ntawm cov khoom no yog siv ncaj qha rau cov nroj tsuag. Yog tias ua tau, sim tshuaj tsuag ob sab saum toj thiab hauv qab ntawm nplooj. Qhov no yuav pab txhim kho kev nqus ntawm cov kab mob.

Kev tshuaj tsuag, koj yuav tsum npaj cov tshuaj. Txhawm rau ua cov berries, txiv hmab txiv ntoo thiab paj, nws yog txaus rau dilute 3 g ntawm zinc sulfate nyob rau hauv 10 liv dej. Koj tuaj yeem saturate cabbage thiab cucumbers los ntawm kev sib tov 5 g ntawm chiv nyob rau hauv tib tus nqi ntawm cov dej. Tab sis rau kev ua cov txiv lws suav thiab ntau yam hauv paus qoob loo, koj yuav xav tau 10 g ntawm zinc sulfate.

Txoj kev txau yog nqa tawm tsuas yog thaum huab cua txias thiab qhuav. Kev ua haujlwm yog qhov zoo tshaj plaws thaum yav tsaus ntuj lossis sawv ntxov, tsis txhob tshav ntuj kub.

Zinc sulfate kuj tuaj yeem siv rau hauv av. Qhov no yog ua los ntawm lub hauv paus ntawm 1 sq. m ntawm av yuav tsum tau txais 1 g ntawm zinc sulfate.

Cov cim qhia sab nraud ntawm micronutrient deficiency

Zinc sulfate yog ib qho tshuaj tua kab mob zoo heev. Nws yog cov xim tsis muaj xim crystalline nrog qhov ntom ntawm 3.74 g / cm 3. Zinc sulfate yog tau los ntawm dissolving cov ntsiab lus uas muaj cov hlau no nyob rau hauv sulfuric acid. Qhov tshwm sim tsis xav tau impurities raug tshem tawm los ntawm kev ua kom huv tshwj xeeb.

Nrog tsis muaj zinc, txiv hmab txiv ntoo cuam tshuam los ntawm kab mob rosette. Cov nplooj me me chlorotic yog pom ntawm qhov kawg ntawm cov ceg. Lawv tsim ib lub qhov (socket). Nyob rau tib lub sijhawm, hauv paus kev loj hlob yuav qaug zog. Yog tias tsis muaj zinc ntau dhau, ces cov teeb meem cuam tshuam cov ceg yuav pib tuag.

Koj tuaj yeem pom qhov tsis muaj zinc hauv pob kws. Nws cov nplooj tshiab yuav yog lub teeb daj lossis dawb. Cov kab txaij daj tsim rau cov laus. Cov pob kws zoo li no yuav tsawg.

Koj tuaj yeem tau txais cov txiaj ntsig zoo tshaj yog tias koj npaj ua ntej cog. Piv txwv li, pre-sowing kev kho mob ntawm pob kws noob yog nqa tawm raws li nram no: lawv yog dusted nrog ib tug tshwj xeeb sib tov uas muaj 42 g ntawm zinc sulfate thiab 150 g ntawm talc. Tus nqi no txaus los ua 1 xees ntawm cov noob.

kev kho ua ntej sowing ntawm cov noob ntawm lwm cov nroj tsuag yuav ua tau txawv. Ntau tus pom zoo kom soaking lawv nyob rau hauv dej uas muaj ntau yam kab kawm tau yaj, suav nrog zinc sulfate. Tab sis koj tuaj yeem muab cov noob tso rau hauv kev daws nrog chiv tsis pub ntau tshaj ib hnub.
