Abstract: The study shows that the content of nutrient elements in various organs of masson pine is in order of needle>branch bark>stem bark>branch wood>stem wood, that in assimilated organ is in order of N>K>Ca>Mg>P, and that in non-assimilated organ is in order of Ca>N>K>Mg>P. The accumulated amount of nutrient elements in various organs is in order of stem wood>stem bark>needle>branch wood>branch bark, that in assimilated organ is in order of N>K>Ca>Mg>P, and that in non-assimilated organ is in order of Ca>N>K>Mg>P. The content of nutrient elements in1000kg dry matter under various site conditions is different. The better site condition, the higher efficiency of nutrient elements, and less accumulated amount. Parent rock, soil depth and total soil nutrient content are the major factors affecting the nutrient content of aboveground organs and of needles in particular. The higher soil Nand Pcontent, the greater biomass in masson pine plantation.
