Tsis siv neeg granulation khoom
Cov cuab yeej siv tsis tau granulation yog siv los tsim cov tshuaj tsis haum lossis qeeb-tso chiv.Cov hom chiv no yog tsim los tso cov zaub mov maj mam dhau lub sij hawm ntev, txo qhov kev pheej hmoo ntawm kev fertilization ntau dhau thiab cov khoom noj leaching.Tsis siv neeg granulation khoom siv ntau yam txuj ci los tsim cov hom chiv no, suav nrog:
1.Coating: Qhov no suav nrog txheej txheej ntawm cov chiv granules nrog cov khoom siv uas ua rau qeeb ntawm kev tso tawm ntawm cov as-ham.Cov khoom siv txheej tuaj yeem yog polymer, siv quav ciab, lossis lwm yam khoom siv.
2.Encapsulation: Qhov no suav nrog kev ntim cov chiv granules hauv cov tshuaj ntsiav ua los ntawm cov khoom siv qeeb qeeb, xws li polymer lossis resin.Lub capsule maj mam dissolves, tso cov chiv thaum lub sij hawm.
3.Blending: Qhov no suav nrog kev sib xyaw cov chiv sib txawv nrog cov nqi sib txawv los tsim kom muaj kev tso tawm qeeb lossis tsis muaj chiv.
Cov cuab yeej siv tsis tau granulation tuaj yeem siv ntau txoj hauv kev los ua kom tiav cov txheej txheem no, xws li cov ntaub ntawv hauv av, tshuaj tsuag granulation, lossis nruas granulation.Cov cuab yeej siv tshwj xeeb yuav nyob ntawm seb hom kev xav tau thiab hom chiv tau tsim.
Cov khoom siv tsis siv neeg granulation muaj ntau yam txiaj ntsig, suav nrog:
1.Reduced fertilizer daim ntawv thov zaus: Buffer chiv tuaj yeem tso cov as-ham maj mam dhau lub sijhawm ntev, txo qhov xav tau ntawm kev siv chiv ntau zaus.
2. Txo cov zaub mov tsis zoo: Kev tso tawm qeeb lossis tsis muaj chiv tuaj yeem pab txo cov zaub mov leaching thiab dej ntws tawm, txhim kho cov txiaj ntsig ntawm kev siv chiv thiab txo cov pa phem ib puag ncig.
3.Txhim kho cov nroj tsuag kev loj hlob: Buffer chiv tuaj yeem muab cov khoom noj tsis tu ncua rau cov nroj tsuag, txhawb kev loj hlob zoo thiab txo qhov kev pheej hmoo ntawm cov zaub mov tsis txaus.
Cov khoom siv tsis zoo granulation ua lub luag haujlwm tseem ceeb hauv kev tsim cov tshuaj qeeb qeeb thiab tsis muaj chiv, uas tuaj yeem muab txiaj ntsig ntau rau cov neeg ua liaj ua teb thiab ib puag ncig.
