Abstract

Abstract: The accumulation and distribution of nutrient elements in a 12-year-old Castanopsis fissa plantation was studied．The results showed that the net-accumulation of nutrient elements is 81.59kg/hm²·a，in which K is 51.5％and N is 31.6％．Net-accumulation of mieronutrients is 2.756kg/hm²·a，in which Fe is 53.6％and Mn is 38.7％．The net-ac-cumulation of nutrient elements in leaves is higher than that in other organs．The re- quirement to produce one ten dry biomass is 10.25kg for nutrient elements and 346.2g for micronutrients．

Key words: Castanopsis fissa, Nutrient element
