2026-09-09 Dataset of effects of nitrogen and phosphorus addition on microbial carbon use efficiency and root traits in the rhizosphere soil of Phyllostachys edulis rhizome roots doi:10.57760/sciencedb.cjae.0009p en This dataset originates from a field nitrogen and phosphorus addition experiment in a Moso bamboo (Phyllostachys edulis) forest in Lin'an District, Hangzhou, Zhejiang Province, China. Four treatments were established: control (CK), nitrogen addition alone (N), phosphorus addition alone (P), and combined nitrogen and phosphorus addition (NP), with three replicates each. After 19 months of continuous fertilization, fine roots (diameter ≤ 2 mm) attached to bamboo rhizomes and their associated rhizosphere soils were collected. The following parameters were measured and recorded: (1) rhizosphere soil physicochemical properties, including pH, soil organic carbon (SOC), total nitrogen (TN), total phosphorus (TP), available nitrogen (AN), available phosphorus (AP), and phosphorus fractions (CaCl₂-P, Citrate-P, Enzyme-P, HCl-P); (2) soil microbial properties, including microbial biomass carbon (MBC), nitrogen (MBN), phosphorus (MBP), activities of carbon-acquiring enzyme (βG), nitrogen-acquiring enzymes (NAG, LAP), and phosphorus-acquiring enzyme (ACP), as well as microbial carbon use efficiency (CUE) derived from ecoenzymatic stoichiometry; (3) rhizome root traits, including root carbon, nitrogen, and phosphorus contents, root mean diameter (RD), specific root length (SRL), specific root area (SRA), root tissue density (RTD), root phosphatase activity (RPA), arbuscular mycorrhizal fungi (AMF) colonization rate, and spore density. This dataset provides foundational data for understanding the responses of rhizosphere microbial carbon metabolism to nutrient inputs in subtropical Moso bamboo forests, and is applicable to research in forest soil carbon cycling, root ecology, and nutrient management Phyllostachys edulis; rhizome root; rhizosphere soil; microbial carbon use efficiency; nitrogen and phosphorus addition; root traits; soil enzyme activity; nutrient limitation chen jing Wang Shanfeng Ren Qingyan Zhou Shijie Li Haicheng Xie Jingchen Schiemann Li Quan Song Xinzhang RESTRICTED dataset Science Data Bank
