Tsis siv neeg ntim tshuab hluav taws xob txhim kho kev ua tau zoo, kev yug dua tshiab ntawm cov kev lag luam ntim khoom, yog nqa tawm ntawm cov tshuab raj ntawm kev ua haujlwm ntawm phau ntawv phau ntawv yog los ua ib yam yav dhau los .} Cov tshuab no tuaj yeem ua tiav cov txheej txheem chiv keeb kwm xws li tsis siv neeg ntim tshuab hluav taws xob tau txhim kho kev ua tau zoo thiab qhov raug:
1.}}} Txoj kev siv bagging ceev: kev ua haujlwm ntim ntawm ntau txhiab tus txiv neej ua haujlwm tau sai dua li ntawd ntawm cov hnab ntawm cov khoom siv thiab kev txhim kho ntau dua li ntawd ntawm cov hnab siv ntau lawm, kev txhim kho ntau dua li ntawd ntawm kev txhim kho lub voj voog thiab kev txhim kho ntau dua li ntawd ntawm kev txhim kho lub voj voog thiab txhim kho ntau dua kev ua haujlwm.
2.} Nrhiav kom raug qhov tseeb: zam qhov tshwm sim ntawm lub tshuab ua haujlwm ntau dhau los, tsis txhob lav cov khoom lag luam tab sis tseem tuaj yeem lav cov khoom lag luam zoo {}}
{{03. txo kev siv zog ua haujlwm, uas tsis yog siv tau ntau yam kev ua haujlwm kom muaj kev nyab xeeb thiab ua haujlwm rau kev nyab xeeb ntawm kev ua haujlwm ib puag ncig.
4.}} Kev hloov kho rau ntau yam chiv: Hmoov tsis zoo rau lawv cov yam ntxwv thiab hnab lawv.
{5. Tus nqi txo qis: Txawm hais tias cov khoom siv ntim khoom siv tau ntau, tsis siv neeg ntim cov nqi ua haujlwm, thiab yog li qis dua cov nqi ntau lawm.
Raws li lub tswv yim tsim hauv fertilizing hnab looj tes, tsis siv neeg cov khoom ntim khoom txuas ntxiv rau kev ua kom muaj zog ntawm cov tshuab
