Formulation of substrates with agricultural and forestry wastes for Camellia oleifera Abel seedling cultivation

Five Camellia oleifera Abel seedling substrates were prepared using the conventional formula, but with the peat substituted by the composts of Camellia oleifera shell, pine chips, palm fiber residues, chicken manure, and sheep manure. The physical and chemical properties of the prepared substrates b...

Description
Summary:Five Camellia oleifera Abel seedling substrates were prepared using the conventional formula, but with the peat substituted by the composts of Camellia oleifera shell, pine chips, palm fiber residues, chicken manure, and sheep manure. The physical and chemical properties of the prepared substrates before and after seedling cultivation were determined and their effects on the growth of Camellia oleifera seedling were analyzed. It was found that the survival rates of the one-year-old seedlings produced from stem cuttings on all substrates at 6 months were greater than 97.5%. As compared with the conventional substrate, the substrates formulated with the composts were able to promote the seedling growth based upon height, ground diameter, root length and root volume measurement. The substrate prepared with the compost of Camellia oleifera shell+ palm fiber residue+ chicken manure (A3), vermiculite and perlite (6:3:1) was the most optimal, which gave 100% seedling survival rate, the greatest seedling height, and the largest ground diameter. In particular, the ground diameters and 26.67% of the seedling heights reached the grade 1 standard for two-year-old seedlings.
