[Abstract]Objective Tooptimize the key techniques forseedling cultivation of Acorus tatarinoui Schottseeds，expand the propagationofhighqualityseedlings，andreduceplantingcosts.MethodsQuartzsandofdiferentparticlesizes（O.120.0.4， 0.4～10，1.0～02.0～3030～5.0，50～8.0，80～12.0mm）wasmixedwithpeatina1：1（v）ratioasthegrowthmedium.The germination and seedling growth of Acorus tatarinowii Schottseeds were compared under constant temperature （25 C ）and light cultivationconditions.ResultsThemixedsubstrateofquartzsandwithdiferentparticlesizeshadsignificantefectsonthe germinationrateandgerminationpotentialofAcorustatarinowi Schottseeds.Amongthem，themixturewitO.2-0.4mmquartzsand showed the highest germination rate 88.89%±6.94% ）and germination potential （ 78.89%±1.92% ）.The mixed matrix of quartz sand withvaryinggrainsizessignificantlyafectsgrowthindicatorssuchasplantheight，maximumleaf widthmaximumleaf legth， numberofrootbranches，andmaximumrotlengthoftheAcorustatarinowiiSchotseedlings，buthasosignificantfectsonleaf number.During theseedling growth stage，Acorustatarinoui Schottseedlingscultivatedinpurepeatsubstrateshowedoptimal performanceacross allgrowthanddevelopmentindicators.Conclusion Themixedsubstrateof quartzsandand peatwith dierent particlesizes hassignificantefectsontheseedgerminationandseedlinggrowthofAcorustatarinoui SchottConsideringbothcost and efctivenessin practical production，pure peatisan ideal substrate forseed germinationandearly seeding growth.
