| Abstract: | The regression analysis results of the blade nutritional elements of different plantations of Cunninghamia lanceolata and the N,P and K nutritional elements in the soil show that the regression of the N and P content in the blades with different forest ages and the N and P content in the soil assumes extremely significant positive correlation whereas the correlation between the K content in the blades and the K content in the soil is not significant. |
