Density Effect on the Nutrient Distribution of Elaeocarpus Sylvestris Seedlings

With Elaeocarpus Sylvestris seedlings as the experimental materials, the density effect on nutrient distribution of the seedlings was studied. The results showed that nitrogen concentration decreased in the order of leaves > branches > roots > stem, phosphorus concentration varied without regular patterns, whereas potassium concentration was leaves > branches > stem > roots in E. Sylvestris seedlings. Accumulation of nitrogen, phosphorus and potassium increased with increasing density. Generally, the nutrient accumulation was great in roots and small in branches.
