Abstract: The experiment was conducted to study the effects of different substrate material on Camellia oleifera container seedlings, and find out the local substrates instead of peat soil content. One-year-old C.oleifera container seedlings of different substrate treatments were tested in several indicators such as survival rate, growth, biomass, the contents of chlorophyll and nutrient elements aboveground, and the correlation between substrate and contents of nutrient element aboveground was also analyzed. The indexes including survival rate, height of seeding, ground diameter, ratio of height to ground diameter, tap root length, tap root/lateral root fresh weigh, aboveground/underground biomass, the diameter root ratio/FW, the diameter root ratio/DW, and contents of chlorophyll were superior in treatment Ⅰ(50% Peat soil+50% the rest of the same composition) and treatment Ⅴ(5% the rest of edible mushroom+5% fowl dung+5% cow dung+35% Peat soil+50% the rest of the same composition), and there was significant difference between them and other three treatments. There was significant difference in the contents of N, P, K, Ca, S, Fe, Mn, Cu and Zn, and no significant difference in B and Mg between different treatments. The correlation analysis showed that Mg and available potassium, organic matter had significantly positive correlation, and others had negative correlation. Therefore, the best substrate was treatment Ⅴ, in which local substrate instead of part of the peat soil. The study would provide a new way of reducing seedling costs and maintaining sustainable utilization of substrate.
