Kev tshawb fawb tau pom tias qhov zoo tagnrho ntawm cov as-ham rau cov paj ntoo yog 3-1-2. (Qhov ntawd yog 3% Nitrogen, 1% phosphorus & 2% potassium.) Yog li nrhiav qhov piv ntawm cov ntawv ntim cov chiv; txhua yam nyob ze ntawm 3-1-2, 6-2-4 lossis 9-3-6 yuav tsum yog qhov zoo.
Npaj zoo NPK yog dab tsi?
NPK zoo tshaj plaws rau koj lub vaj, ntim thiab cov nroj tsuag hauv tsev yog a 3-1-2 ratio Nco ntsoov tias qhov no yuav tsum tau hloov kho rau cov as-ham uas twb muaj lawm. Ntau cov av muaj phosphate txaus thiab yog li koj tsis tas yuav ntxiv ntxiv. Koj cov av kuj tseem yuav muaj cov poov tshuaj txaus.
Puas siab dua NPK zoo dua?
Peb tus lej ntawm cov chiv yog tus nqi ntawm peb cov khoom noj khoom haus uas siv los ntawm cov nroj tsuag. Cov macro-nutrients yog nitrogen (N), phosphorus (P), thiab poov tshuaj (K), los yog NPK luv luv. Tus lej ntau dua, qhov ntau cov ntsiab lus muaj nyob hauv cov chiv
Yuav ua li cas chiv yog qhov zoo tshaj plaws rau cog kev loj hlob?
Kev xaiv chiv Feem ntau cov neeg ua teb yuav tsum siv
ua tiav cov chiv nrog phosphorus ntau dua li nitrogen lossis potassium Piv txwv yuav yog 10-20-10 lossis 12- 24-12. Cov chiv no feem ntau yog yooj yim nrhiav. Qee cov av muaj cov poov tshuaj txaus rau cov nroj tsuag loj hlob zoo thiab tsis xav tau ntau dua.
NPK piv rau cov nroj tsuag yog dab tsi?
Ua tau zoo tshaj plaws, N-P-K- piv yog feem pua cov khoom muaj los ntawm ntim ntawm nitrogen (tshuaj cim N), phosphorus (P), thiab poov tshuaj (K). Piv txwv li, 16-16-16 chiv, muaj 16% nitrogen, 16% phosphorus, thiab 16% potassium.
