Lub luag haujlwm tseem ceeb ntawm cov noob qoob loo cog qoob loo yog los hloov cov kev coj noj coj ua ntawm kev cog qoob loo rau hauv cov txheej txheem kev tsim khoom, kev ua haujlwm tas mus li, thiab cov txheej txheem tsim tawm, ua kom muaj txiaj ntsig zoo thiab ruaj khov.
Hauv cov ntsiab lus ntau lawm, lub kaw lus cia li tswj cov txheej txheem tseem ceeb xws li substrate filling, precision seeding, npog, thiab irrigation. Qhov no ua kom yooj yim rau tag nrho cov chaw zov me nyuam ua haujlwm, txo qis kev siv zog ua haujlwm, thiab ua kom cov khoom siv tau zoo, ua rau nws tsim nyog rau qhov loj - cov kev xav tau ntau lawm.
Nyob rau hauv cov nqe lus ntawm kev tswj kom zoo, lub kaw lus ua kom zoo ib yam loj hlob nyob rau hauv tag nrho cov ntsaws trays los ntawm meej seeding thiab zoo ib yam substrate tuav. Qhov no txhim kho germination uniformity thiab seedling zoo thaum txo qis variations tshwm sim los ntawm tib neeg lub lag luam, ua rau kom muaj kev vam meej ntau dua.
Los ntawm kev saib xyuas kev tswj hwm, cov txheej txheem kev ua haujlwm ua rau muaj kev tswj xyuas zoo dua thiab kev taug qab ntawm cov txheej txheem chaw zov me nyuam, txhawb kev tswj hwm kev sib koom ua ke thiab kev tsim khoom, thiab txhim kho tag nrho cov koom haum ua haujlwm.
Tsis tas li ntawd, lub kaw lus tso cai rau kev hloov pauv hloov pauv raws li qhov xav tau ntawm cov qoob loo sib txawv, ua kom muaj ntau- ntau yam kev tsim khoom thiab muab kev ruaj khov thiab muaj txiaj ntsig zoo rau kev ua liaj ua teb niaj hnub no.
