Abstract: Based on analysis of the contents of N,P,K in Fargesia murielae ,the results showed that the distribution of N,P,K varied significantly from periods to organs.The contents of N,P in different organs were ranked as follows:leaf>rhizome,root>culm.The potassium contents in descending order were rhizome,root,leaf,culm both in non-flowering bamboos and flowering bamboos,and were leaf,rhizome,culm,root in blossomed bamboos.In the process of flowering,the contents of nitrogen decreased;the contents of phosphorus reduced in organs such as culm,rhizome,root,and appeared a changing trend of ascend-descend in leaf;the contents of potassium reduced both in rhizome and root,and appeared a changing trend of descending first and then ascending both in culm and leaf.
