AbstractTo study the growth status of Chinese fir seedlings in light substrate container under different seedlingconditions.In 2024，sand buried plug and aerialplugseedling experiments willbecarried out.From the aspects of growth，biomass，interval distribution，quality index，membership function values，and correlation.The results indicate that： in addition to root dry weight and root shoot ratio，sand buried plug seedlings and aerial plug seedlings.There were significant differences （P<0.05） in other growth and dry weightindicators.The height，grounddiameter，heighttodiameterratio，stemand leafdryweight，rootdry weight，whole plantdry weight，root to shoot ratio，qualityindex，and of sand buried plug seedlings are26.6cm，4.6mm，57.9，3.2g，0.69g，3.9g，0.21，0.06， and 3.0611，respectively;The height， ground diameter， heightto diameter ratio，stemand leaf dry weight，root dryweight，whole plantdryweight，root to shoot ratio，quality index，and of aerial plug seedlings are 1.8g， 0.63g， 2.5g， 0.34， 0.05 ，and 2.996 7， respectively. 100% and 37.5% of the seedlings in the sand buried tray and aerial tray are distributed between （204号 20-40cm in height，respectively 98.9% and 52.3% of the seedlings in the sand buried tray and the aerial tray， respectively，are distributed between 4⋅8mm in diameter.Through comprehensive comparative analysis， Sand buried plug seedlings are superior to aerial plug seedlings.
