Lub luag haujlwm tseem ceeb ntawm lub substrate decompression thiab sib tov tshuab yog kom sai decompress compacted los yog tsis sib xws substrates thiab sib tov lawv uniformly. Nws tseem tuaj yeem suav nrog cov chiv lossis cov tshuaj ntxiv raws li xav tau, txhim kho substrate siv efficiency thiab cov noob zoo. Cov txheej txheem no ua lub luag haujlwm tseem ceeb hauv kev tsim cov noob qoob loo niaj hnub thiab kev tswj hwm kev cog qoob loo.
Ua ntej, lub tshuab sai sai loosens compressed substrates, rov kho cov qauv ntxeem tau uas txhim kho huab cua thiab dej permeability, txhawb cov noob germination thiab hauv paus kev loj hlob. Kev siv cov substrate tsis sib npaug los yog compacted ncaj qha tuaj yeem ua rau cov khoom noj tsis sib haum thiab kev faib dej, cuam tshuam rau cov qoob loo ciaj sia.
Qhov thib ob, kev sib xyaw ua haujlwm kom ntseeg tau tias cov chiv, kab kawm, thiab lwm yam khoom ntxiv tau muab faib ua tus sib npaug thoob plaws hauv substrate. Qhov no tau lees paub tias txhua feem ntawm cov substrate muaj cov ntsiab lus zoo sib xws, txhim kho uniformity thiab tag nrho cov noob zoo.
Tsis tas li ntawd, lub tshuab txo qis kev ua haujlwm ntawm phau ntawv thiab ua kom muaj kev ua haujlwm zoo, ua rau nws tsim nyog rau loj - nplai substrate tuav thaum txo qhov kev pheej hmoo los ntawm kev sib xyaw ntawm phau ntawv tsis sib xws.
Zuag qhia tag nrho, lub luag haujlwm tseem ceeb ntawm lub substrate decompression thiab sib tov tshuab tsis yog tsuas yog txhim kho lub cev ntawm lub substrate, tab sis kuj los txhim kho qhov chaw loj hlob thiab txhim kho cov nroj tsuag sib xws, ua rau nws yog ib qho tseem ceeb hauv kev tsim cov noob qoob loo niaj hnub.
