Partitioning of total variation (%) of C:N, C:P, N:P into species, effects of sampling (sampling date, leaf age, root size) and residual components in the sand culture experiment.

Partitioning of total variation (%) of C:N, C:P, N:P into species, effects of sampling (sampling date, leaf age, root size) and residual components in the sand culture experiment.沙地培养试验中，针对碳氮比（C:N）、碳磷比（C:P）与氮磷比（N:P）的百分比总变异，将其分解为物种效应、采样效应（涵盖采样日期、叶龄与根大小）以及残差组分。
