2026-09-24 Data on carbon, nitrogen and phosphorus contents of litter, fine roots and soil in Machilus pauhoi plantation at Taiping State-owned Experimental Forest Farm, Yanping District, Nanping City, Fujian Province doi:10.57760/sciencedb.013k2 en This study set up a total of four nitrogen and phosphorus addition treatments: control (CK, without adding nitrogen and phosphorus), single nitrogen application (+N, 100 kg N · hm-2 · a-1), single phosphorus application (+P, 10 kg P · hm-2 · a-1), and simultaneous nitrogen and phosphorus addition (+NP, 100 kg N · hm-2 · a-1, 10 kg P · hm-2 · a-1). Each treatment had three replicates, meaning that one of the replicates in one of the treatments was arranged in each of the 12 plots. The fallen leaves, fine roots, and soil of Chinese fir were collected in December 2021 (winter), March 2022 (spring), July 2022 (summer), and September 2022 (autumn) at the Taiping State owned Experimental Forest Farm (118 ° 19 ′ -118 ° 31 ′ E, 26 ° 24 ′ -26 ° 35 ′ N) in Yanping District, Nanping City, Fujian Province. In the dataset processing column, 1 represents control, 2 represents single nitrogen application, 3 represents single phosphorus application, and 4 represents simultaneous addition of nitrogen and phosphorus; Seasonal column 1 represents spring, 2 represents summer, 3 represents autumn, and 4 represents winter.  Machilus pauhoi; Fine root; Soil; Carbon-nitroge-phosphrus contens He Yu Zhong Quanlin Wu Xiping Lin Qiuyan RESTRICTED dataset Science Data Bank
