南亚热带常绿阔叶林粘木种群营养元素的分布与循环(英文)

Studied nutrient distribution,nutrient storage,and annual nutrients uptake in different parts of trees and concluded that nutrients vary in leaves of different mature state and in bark and wood.Internal cycling of N,P,K indicates the conservation recycling of these nutrients.Large amount of nutrients stored in this population indicate which play an important role in the forest.The turnover time of N,P,K,Ca,Mg in the population is 12 1,13 1,18 8,12 2 and 19 04 year respectively.
