To reveal the carbon（C）, nitrogen（N）, and phosphorus（P）allocation strategies of evergreen-broad-leaf seedlings from different species and organs, this study selected six common evergreen broad-leaf seedlings, namely Schima superba, Phoebe bournei, Quercus glauca, Mytilaria laosensis, Castanopsis fordii, and Quercus sessilifolia, as research objects and analyzed the chemical stoichiometry of C, N, and P in evergreen broad-leaf plant seedlings from the perspectives of species characteristics and organ functions. The results showed that:（1）The N content of Phoebe bournei was significantly higher than that of the other species, and Mytilaria laosensis had a high P content as well as low C:P and N:P ratios.（2）The average C and N contents of the leaves of the six seedlings was significantly higher than that of the stems and fine roots, while the average P content of the stems was significantly higher than those of the leaves and fine roots.（3）The N content of all organs showed significant allometry, with the leaf-root N allometry index（1.35）being significantly higher than that of the leaf-stem index（0.79）. The P content of the leaves and stems showed significant allometry, with the allometry index being 1.22. The N-P allometry index of the leaves and fine roots was less than 1, while the P content of the stems showed no significant allometry. The allometric relationships between organs indicate that plants use different strategies to allocate N and P to optimize their growth, with the allocation strategies of the leaves and fine roots showing that they invest more in P than N. This study helps to better understand the nutrient utilization efficiency and nutrient allocation mechanisms among species and organs of common broad-leaf tree during the seedling stage, providing a theoretical reference for the efficient cultivation and nutrient management of artificial forest seedlings.
