摘要: 对12年生黧蒴栲林9种营养元素的积累、分布进行研究,结果表明:该林分大量元素的年均积累量为81.59kg/hm2·a,其中K占51.5%,N占31.6%,微量元素为2.756kg/hm2·a,其中Fe占53.6%,Mn占38.7%;叶片中大量元素的积累量均高于其它器官;每生产lt干物质需大量元素10.25kg,微量元素346.2g。

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.
