The growth of Chinese fir is limited by nitrogen: Evidences from N:P ratio, N or P variability and NuRE based on a regional investigation
Forest Ecology and Management(2020)
摘要
•The mean value of leaf nitrogen (N): phosphorus (P) is significantly less than 14.•Leaf N concentration is less affected by the environmental variables.•Leaf N:P ratio decreases with increasing P resorption efficiency.
