摘要
Abstract
The nutrient percentage contents for non-photosynthetic organs in the sharptooth oak stands are in the following order. N is: barks>branches>roots>sapwood>heartwood, P is: roots>branches>barks>sapwood>heartwood, K is: branches>barks>roots>sapwood >heartwood, Ca is: barks>branches>roots>heartwood>sapwood, Mg is: roots> barks>branches >sapwood>heartwood. The nutrient percentage contents of branches and roots decrease with increase in branch and root diameter，and have difference in different crown layers and soil layers. The nutrient percentage contents of bole xylem and barks raise from base to tip of bole. The nutrient percentage and accumulation contents in different organs are leaves>barks> branches≥roots> boles and branches>boles>barks>roots >leaves respectively. The paper gives a suggestion for sampling number for determined nutrient contents of different organs in sharptooth oak stands.关键词
