- Abstract
In order to reveal the effects of fertilization on the growth of Acacia saplings, experiments were carried out with combinations of Acacia varieties, application methods and fertilizer formulae, recording sapling changes in diameter at breast height (DBH), tree height and volume growth. The result showed that formulae of basal fertilizer significantly influenced DBH and volume growth except height growth; and formulae of surface dressing had no obvious effect on the sapling growth, while there were significant differences in sapling growth among varieties. Factors’ effects on the growth were in such a descending order: varieties > basal fertilizing > surface dressing. Among 9 treatments of orthogonal design, there were significant differences in tree height, DBH and volume (P < 0.05), and treatment A 1 B 2 C 3 and A 2 B 3 C 3 had highest tree height, A 3 B 2 C 2 had highest DBH and volume. This finding may provide insight for the management of Acacia plantations.
