Abstract

The content,accumulation and distribution of ten nutrient elements and biomass in different organs of Pinus massoniana were studied based on field investigation and lab analysis.The results show that:1)the order of total concentrations of nutrient elements in different organs of 2.5 and 8.5-year old Pinus massoniana was leaf>root>twig>trunk and leaf>twig>root>trunk.The order of concentrations of nutrient elements in 2.5 and 8.5-year old Pinus massoniana was N>K>Ca>P>Mg>Mn>Fe>B>Zn>Cu and N>Ca>K>Mg>P>Fe>Mn>Zn>B>Cu.2) The total nutrient accumulations at two different age classes plantation were 180.69 and 617.46 g per plant.The order of accumulations of ten nutrient elements in different organs of 2.5 and 8.5-year old Pinus massoniana was leaf>twig>trunk>root and trunk>twig>leaf>root.The order of accumulations of nutrient elements in 2.5 and 8.5-year old Pinus massoniana was N>Ca>K>P>Mg>Mn>Fe>Zn>B>Cu and N>Ca>K>Mg>P>Fe>Mn>Zn>B>Cu.So the concentrations of nutrient elements in different organs of young Pinus massoniana increased with the increase of age,the total accumulations of nutrient elements in leaf and twig of 2.5 year old trees was recorded as the highest,that of the 8.5 year old ones has become the highest in the trunk and twig.The content and accumulation of nutrient elements in different organs of Pinus massoniana were different.The distribution of nutrient elements in the tree body is not proportional to the biomass of different organ.

Key words： Pinus massoniana; nutrient elements; accumulation; distribution
