Qhov zoo ntawm foliar fertilizer

Advantage 1: High fertilizer efficiency ntawm foliar fertilizer
Nyob rau hauv ib txwm muaj xwm txheej, tom qab siv nitrogen, phosphorus thiab poov tshuaj chiv, lawv feem ntau cuam tshuam los ntawm cov yam ntxwv xws li av acidity, av noo cov ntsiab lus thiab cov kab mob hauv av, thiab tsau thiab leached, uas txo cov chiv efficiency. Foliar fertilizer tuaj yeem zam qhov tshwm sim no thiab txhim kho cov txiaj ntsig zoo. Foliar fertilizer yog txau ncaj qha rau ntawm nplooj yam tsis muaj kev sib cuag nrog cov av, tsis txhob muaj qhov tsis zoo xws li av adsorption thiab leaching, yog li kev siv tus nqi siab thiab tag nrho cov chiv tuaj yeem txo.
Foliar fertilizer muaj kev siv siab heev thiab tuaj yeem txhawb kev nqus hauv paus. Nyob rau hauv cov xwm txheej ntawm kev tswj hwm cov txiaj ntsig zoo ib yam, ntau cov foliar txau tuaj yeem txuag tau 25% ntawm cov av siv nitrogen, phosphorus thiab potassium chiv.

Qhov zoo 2: Foliar fertilizer txuag lub sijhawm thiab kev ua haujlwm
Yog tias foliar chiv yog tov nrog tshuaj tua kab thiab tshuaj tsuag ib zaug, nws tuaj yeem tsis tsuas yog txuag cov nqi khiav lag luam, tab sis kuj txhim kho kev ua tau zoo ntawm qee yam tshuaj tua kab. Cov kev sim tau pom tias cov tshuaj tsis muaj zog thiab cov organic nitrogen sib txuas hauv foliar chiv txhawb kev nqus thiab hloov cov tshuaj tua kab; surfactants tuaj yeem txhim kho qhov diffusion ntawm cov chiv thiab tshuaj tua kab ntawm nplooj thiab ua kom lub sijhawm nqus ntawm cov as-ham soluble ntev; tus nqi pH ntawm foliar chiv tuaj yeem tsim cov nyhuv buffering thiab txhim kho qhov nqus ntawm qee yam tshuaj tua kab.

Advantage 3: Fast-acting foliar fertilizers
Foliar chiv ua sai tshaj li cov hauv paus chiv keeb, thiab foliar fertilization tuaj yeem txhim kho cov khoom noj khoom haus ntawm cov nroj tsuag raws sijhawm thiab sai. Feem ntau hais lus, foliar fertilization yog nrawm dua li cov hauv paus nqus. Piv txwv li, tshuaj tsuag 1-2% urea aqueous daws ntawm nplooj tuaj yeem nqus tau 1/3 tom qab 24 teev; Txau 2% superphosphate extract tuaj yeem thauj mus rau txhua qhov chaw ntawm cov nroj tsuag tom qab 15 feeb. Nws tuaj yeem pom los ntawm qhov no tias foliar fertilization tuaj yeem ntxiv cov as-ham uas xav tau los ntawm cov nroj tsuag hauv lub sijhawm luv luv thiab xyuas kom muaj kev loj hlob zoo ntawm cov nroj tsuag.

Advantage 4: Tsawg cov pa phem ntawm foliar chiv
Nitrate yog ib qho ntawm cov carcinogens. Vim tias tsis muaj kev tshawb fawb thiab kev siv ntau dhau ntawm cov chiv nitrogen, nitrates tau sau rau hauv cov dej saum npoo av thiab cov qoob loo zaub, uas tau nyiam ntau ntxiv. 75% ntawm nitrates nqus tau los ntawm tib neeg los ntawm cov qoob loo zaub. Yog li ntawd, foliar fertilization rau zaub cog tsis tau tsuas yog txo cov av nitrogen chiv, tswj lub tsim tawm los, tab sis kuj txo cov pa phem-dawb zaub.

Advantage 5: Foliar fertilizer yog tsom heev
Cov qoob loo twg tsis muaj ntxiv? Thaum lub sij hawm kev loj hlob thiab kev loj hlob ntawm cov nroj tsuag, yog hais tias ib tug tej yam tsis muaj, nws deficiency yuav sai sai tshwm rau ntawm nplooj. Piv txwv li, thaum cov qoob loo tsis muaj nitrogen, cov noob feem ntau tig daj; thaum lawv tsis muaj phosphorus, cov yub tig liab; Thaum lawv tsis muaj poov tshuaj, cov nroj tsuag loj hlob maj mam, nplooj yog tsaus ntsuab, thiab thaum kawg txiv kab ntxwv-liab chlorotic me ntsis tshwm. Raws li cov yam ntxwv ntawm cov qoob loo tsis muaj peev xwm, cov tshuaj tsuag raws sij hawm tuaj yeem siv los ntxiv cov ntsiab lus uas ploj lawm los txhim kho cov tsos mob.

Qhov zoo 6: Foliar fertilizer tuaj yeem ntxiv qhov tsis muaj as-ham los ntawm cov hauv paus hniav
Nyob rau hauv lub yub theem ntawm cov nroj tsuag, lub hauv paus system tsis zoo tsim thiab lub peev xwm nqus tau tsis muaj zog, uas yog nquag mus rau daj thiab tsis muaj zog seedlings. Nyob rau theem tom ntej ntawm cov nroj tsuag kev loj hlob, cov hauv paus kev ua haujlwm poob qis thiab muaj peev xwm nqus cov as-ham tsis zoo. Yog li ntawd, foliar fertilization tuaj yeem ua rau kom muaj txiaj ntsig. Tshwj xeeb tshaj yog rau txiv hmab txiv ntoo thiab zaub qoob loo, cov nyhuv ntawm foliar fertilization yog pom tseeb dua.
Txawm li cas los xij, qhov concentration thiab qhov nyiaj ntawm foliar chiv yog txwv, thiab nws tsis tuaj yeem txau rau hauv ntau qhov, tshwj xeeb tshaj yog rau macronutrients thiab cov ntsiab lus me me, yog li nws tuaj yeem siv rau cov kab uas muaj tsawg dua.
