1. Lub luag haujlwm ntawm zinc hauv cov qoob loo loj hlob:
Nws cuam tshuam nrog hauv cov metabolism ntawm aulexin (iaa) thiab nucleic acid / protein synthesis, txiav txim siab qhov tseem ceeb ntawm maub ceeb.
Nws yog tus yuam sij rau enzyme: ntau dua 300 enzymes nyob ntawm zn (xws li dej cawv, RNA polymerase, thiab lwm yam), ua pa, thiab antioxidant txheej txheem.
Membrane thiab kev nyuaj siab kuj: tswj cov roj ntsha Membrane kev ntseeg siab thiab txhim kho kev ruaj khov nyob rau hauv ntuj qhuav, thiab patological ntxhov siab.
Pollination / Txiv Hmab Txiv Ntoo Teeb: Txaus
2. Vim li cas zinc sib txawv tshwm sim?
Alkaline/calcareous soil (pH>7.5) Los yog dej khov siab hss hoso → zn²⁺ tsau los ntawm carbonate / hydroxide thiab tsis muaj txiaj ntsig.
Phosphorus dhau (P {-}} indictive zinc defagency inhibition zn nqus cov ntsev ua kua qaub rau hauv paus.
Cov khaub thuas txias thiab ntub / waterlogging / cua → Cov hauv paus hniav tsis muaj zog hauv cov haujlwm thiab qeeb hauv diffusion, thiab tsis tuaj yeem nqus.
Cov av xuab zeb / qis cov organic teeb meem / qis cec → yooj yim rau lim, muaj peev xwm khaws cia; Tau ntev ntev, tsuas yog NPK yog caum, thiab ib qho me me ntawm "ntev - lub khoom siv yog txiav".

5. Kev taw qhia
Txiv lws suav / kua txob / Dib
2-3 lub lis piam ua ntej tawg: muab ZN ntawm 0.1-0.2 mg / u rau cov hauv paus hniav, zoo tshaj plaws siv amino zn; Yog tias "nplooj tshiab internodes yog luv luv", Foliar tshuaj tsuag edta zn ntawm diluted ntawm 1000-1500 zaug rau 1-2 zaug.
Txiv hmab txiv ntoo teeb - txiv hmab txiv ntoo me me: Foliar tshuaj tsuag zn thiab b raws li daim ntawv lo; Tswj cov nyiaj tsawg ntawm cov hauv paus ntawm cov hauv paus hniav, tswj cov khoom lag luam siab / siab hses hiaces khoom thaum lub foliar ntawm Zn.
Lub sijhawm hloov xim hloov: tsom rau K / Mg / B tus nqi haus, kom cov ZN tsawg ntawm cov hauv paus hniav; Zam kev mob phosphorus ntau dhau uas ua rau cov lus tsis txaus ntseeg theem nrab.
Grapes / txiv av apples / citrus
Tom qab nplooj nplooj poob / dormancy los yog ua ntej lub paj ntoo tawg tuaj yeem siv cov sulfate siab ntawm zinc sulfate hauv cov txheej txheem huv (raws li cog kev tiv thaiv kev paub).
Nplooj Tshaj Tawm Tshaj Tawm -}} Ua ntej ua ntej tawg: Foliar tshuaj tsuag edta zn ntawm diluting ntawm 1000-1500 zaug rau 1-2 zaug; Lub vaj nrog cov av alkaline / muaj kev kub ntxhov, tswj cov zn ntawm 0.1-0.2 mg / u rau cov hauv paus hniav.
Cov txiv hmab txiv ntoo theem: tswj hwm ZN thiab Togherher B kom ua kom cov txiv ntoo thiab kev thauj.
Pob kws / nplej
(Cov ntsiab lus) Ntxiv zinc rau cov hauv paus hniav thaum lub sij hawm seedling / banded floting ntawm ib tug me me ntawm cov zn) tuaj yeem txo "lub siab dawb / muaj cov nplooj me me." EDTA ZN tau pom zoo kom zoo
