The Effect of Different Substrates on the Seedling Growth of Larix gmelinii
In order to explore the effects of different substrates on the growth of Larix gmelinii seedlings and evaluate the effects of various substrate treatments on the growth indexes and biomass of seedlings,scientific substrate selection and management sugges-tions were provided for the cultivation of Larix gmelinii and other tree species.Observation experiment on the growth of Larix gmeli-nii seedlings under different substrate treatments.The results showed that different substrates had significant effects on the growth of Larix gmelinii seedlings.Treatment group C(40%raw soil,20%mushroom residue,20%sludge,20%sand)had the best seedling growth effect,and all indexes were significantly higher than other treatment groups,indicating that the matrix combination with mushroom residue,sludge,sand and other components could significantly promote the growth and biomass accumulation of Larix gmelinii seedlings.This study provided theoretical basis for the scientific breeding of Larix gmelinii seedlings.
