1. Fertilize raws li qhov tseeb ntawm cov av thiab cov qoob loo
Tus nqi thiab ntau yam ntawm cov chiv tau txiav txim siab tsim nyog raws li qhov muaj peev xwm ntawm cov av, PH nqi, thiab cov yam ntxwv ntawm cov chiv yuav tsum tau ua ntawm cov qoob loo.
2. Sib tov nitrogen, phosphorus, potassium, organic chiv, thiab micronutrient chiv
Kev sib xyaw-siv ntawm ntau lub ntsiab lus thiaborganic chiv or composttuaj yeem txo qhov adsorption thiab fixation ntawm phosphorus hauv av thiab nce qhov kev siv piv ntawm chiv.Raws li cov qoob loo sib txawv, 6-12 kg ntawm micronutrients chiv tau siv rau txhua qhov Acre.
3. Daim ntawv thov sib sib zog nqus, daim ntawv thov ntau, thiab daim ntawv thov txheej
Daim ntawv thov sib sib zog nqus yog ib txoj hauv kev tseem ceeb los ua kom cov nitrogen siv tau zoo thiab txo cov nitrogen poob, uas tuaj yeem tsis tsuas yog txo cov ammonia volatilization tab sis kuj txo qis denitrification poob, ntawm qhov tod tes, txo cov tshuaj fixation tuaj yeem ua rau kom muaj qhov sib txawv ntawm cov qoob loo hauv paus thiab txhawb kev txhawb nqa. phosphorus los ntawm cov qoob loo.Tsis tas li ntawd, kev txav ntawm phosphorus hauv av tsis zoo.
4. Siv cov tshuaj maj mam tso tawm
Nws paub tias kev siv cov tshuaj qeeb-tso tawm tuaj yeem txo cov tshuaj chiv thiab txhim kho kev siv tus nqi.Cov nyhuv ntawm qeeb-tso chiv yog ntev tshaj 30 hnub, qhov poob ntawm leaching volatilization yog txo, thiab tus nqi ntawm cov chiv yuav txo tau los ntawm 10% -20% tshaj li cov pa chiv.Nyob rau tib lub sijhawm, kev siv cov tshuaj maj mam tso tawm tuaj yeem ua rau kom muaj txiaj ntsig thiab nyiaj tau los.Tom qab daim ntawv thov, cov nyhuv ntawm cov chiv yog ruaj khov thiab ntev, lub sij hawm tom qab tsis tag, kab mob-resistant, thiab chaw nyob-resistant, thiab cov qoob loo tuaj yeem nce ntau dua 5%.
5. Cov tshuaj fertilization
Qhov kev sim tau pom tias kev siv cov chiv tuaj yeem nce los ntawm 5% -10%, qhov muag tsis pom kev fertilization tuaj yeem zam tau thiab cov khib nyiab ntawm cov chiv tuaj yeem txo.Nyob rau hauv qhov tseeb tus nqi, tus nqi ntawm nitrogen absorbed los ntawm cov qoob loo, tus nqi ntawm cov residual chiv nyob rau hauv cov av, thiab tus nqi ntawm cov chiv poob ntxiv nrog rau qhov nce ntawm cov nyiaj nitrogen fertilizer thov, thaum nyob rau hauv tus nqi txheeb ze, cov nitrogen siv efficiency txo nrog. qhov nce ntawm tus nqi ntawm fertilizer thov, tus nqi ntawm poob nce nrog nce ntawm fertilizer daim ntawv thov.
6. Siv nws ntawm lub sijhawm kom raug
Lub sijhawm khoom noj khoom haus tseem ceeb thiab lub sijhawm ua haujlwm siab tshaj plaws yog ob lub sijhawm tseem ceeb rau cov qoob loo kom nqus tau cov as-ham.Peb yuav tsum tuav ob lub sijhawm no kom ntseeg tau tias qhov ua tau zoo tshaj plaws ntawm cov chiv thiab qhov yuav tsum tau muaj cov as-ham rau cov qoob loo.Feem ntau, lub sij hawm tseem ceeb ntawm phosphorus yog nyob rau hauv prophase ntawm kev loj hlob, thiab lub sij hawm tseem ceeb ntawm nitrogen yog me ntsis tom qab ntawm phosphorus.Lub sijhawm ua haujlwm siab tshaj plaws yog lub sijhawm los ntawm kev loj hlob vegetative mus rau kev loj hlob ntawm kev loj hlob.
