Results of one-way ANOVAs of accumulative soil enzyme activities in a Bambusa pervariabilis × Dendrocalamopsis daii plantation (mean ± SE, n = 3).

CK, LN, MN and HN denote control (without N added), low nitrogen (50 kg N ha−1 year−1), medium nitrogen (150 kg N ha−1 year−1), high nitrogen (300 kg N ha−1 year−1), respectively; βF = β-Fructofuranosidase; AcPh = acid phosphatase; PhOx = Phenol oxidase; POD = peroxidase; CAT = catalase. Different letters within the same column indicate significant difference among treatments (one-way ANOVA followed by Fisher's least significant difference test, α = 0.05).
