The Study on the Accumulation and Distribution of Nutrient in Fokienia hodginsii Plantation

The accumulation and distribution of nutrient in Fokienia hodginsii plantation were studied. The results showed: The content of N, P, K in the needle gradually decreased from the bottom to the top along the continual slope, so did the accumulation of nutrients. Conversely, the content of Ca, Mg, Fe, Cu, Zn in the needle increased along the continual slope. The content of nutrient in needle was different with the stand ages. The content of N, P decrease, the content of Ca, Mg increased, and the content of K was relatively stable with the growth of tree. In the 10 and 20 age stands, the sequence of the nutrient accumulation in the different parts of the tree was needleroottrunkbranchbark, in the 30 age stand, however, this sequence was roottrunkneedlebranchbark. The total amount of nutrient accumulation was 30 year old20 year old10 year old. The utilization efficiency increased with the tree growth. In the different period of tree growth, there were differences on accumulation and distribution of nutrient.
