Classification thiab Application Scenarios of Potassium Fertilizers

Raws li cov ntaub ntawv tshuaj, poov tshuaj chiv yuav muab faib ua poov tshuaj chloride, poov tshuaj sulfate, poov tshuaj nitrate, thiab lwm yam, nrog rau ntau hom haum rau txawv scenarios:

Potassium Chloride (KCl): Cov ntsiab lus potassium siab (50%-60%), tus nqi qis, tsim nyog rau cov qoob loo (xws li pob kws thiab nplej), tab sis yuav tsum tau siv ceev faj rau cov qoob loo uas muaj cov tshuaj chloride (xws li haus luam yeeb thiab txiv hmab txiv ntoo).

Potassium Sulfate (K₂SO₄): Potassium cov ntsiab lus 48%-52%, kuj muab cov sulfur, haum rau tag nrho cov qoob loo, tshwj xeeb tshaj yog zoo rau chloride- cov qoob loo rhiab heev, ua rau nws yog thawj xaiv rau high-end economic qoob loo.

Potassium Nitrate (KNO₃): Potassium cov ntsiab lus 46%, kuj muab nitrate nitrogen, haum rau kev ua liaj ua teb tsev cog khoom (xws li zaub zaub), tuaj yeem muab cov as-ham sai, tab sis yuav tsum tau sau tseg tias yuav tsum muaj nitrogen poob.

Cov qauv kev lag luam thiab cov lus pom zoo rau kev thov
Raws li Ministry of Agriculture thiab Rural Affairs '"Cov Lus Qhia rau Kev Siv Cov Khoom Siv Kom Zoo," daim ntawv thov ntawm cov poov tshuaj chiv yuav tsum tau txiav txim siab raws li cov txiaj ntsig ntawm cov av, cov qoob loo xav tau ntawm cov poov tshuaj, thiab lub hom phiaj yield. Cov lus qhia dav dav:

Lub hauv paus chiv: Siv 10-15 kg ntawm poov tshuaj sulfate ib mu, incorporating nws tob rau hauv av nrog organic chiv.

Kev hnav khaub ncaws sab saum toj: Thaum lub caij cog qoob loo ntau tshaj plaws (xws li tuber expansion theem lossis xim txiv hmab txiv ntoo- hloov pauv), siv rau hauv kev sib cais, 5-8 kg ib mu txhua zaus.

Foliar Spray: Siv 0.2%-0.3% monopotassium phosphate tov rau tshuaj tsuag, uas tuaj yeem ntxiv cov poov tshuaj sai thiab txo cov tsos mob tsis txaus poov tshuaj.
