A dataset of chemical characteristics of nine common plant species and soil in Yubaiding Nature Reserve, China

This dataset includes leaf chemistry (K, P, C, N, C:N, Tannins, Phenolics) of nine common species and soil nutrient data (total N, total P, total K) and in Yubaiding Nature Reserve, Yunnan, China.Total carbon and nitrogen of leaf and total nitrogen of soil were determined using an Elemental Analyzer(Elementar Vario MAX CN) (General rules for elemental analyzer, JY/T 017-1996). Soil samples were processed by using wet digestion with hydrofluoric acid and perchloric acid (LY/T1234-2015: Potassium determination methods of forest soils; LY/T 1232-2015: Phosphorus determination methods of forest soils) Leaf samples were processed by using wet digestion with nitric acid and perchloric acid (LY/T 1270-1999: Determination of total silica, iron, aluminum, calcium, magnesium, potassium, sodium, phosphorus, sulfur, manganese, copper, and zinc in for-est plant and forest floor). Phosphorus and potassium contents were measured with an ICP (Thermo Fisher iCAP 7400). Measurement of condensed tannin content in plants followed theISO 9648:1988: Sorghum-Determination of tannin content, and total phenolics content was determined by the Folin–Ciocalteumethod (Meda et al.,2005).

本数据集涵盖中国云南玉白顶自然保护区内9种常见植物的叶片化学组分数据（钾K、磷P、碳C、氮N、碳氮比C:N、单宁、酚类物质），以及该区域的土壤养分数据（全氮、全磷、全钾）。其中，叶片总碳、总氮含量与土壤总氮含量均采用元素分析仪（Elemental Analyzer, Elementar Vario MAX CN）测定，测定规程遵循《元素分析仪通用规则》（JY/T 017-1996）。土壤样品采用氢氟酸-高氯酸湿消解法进行前处理，对应测定标准为《森林土壤钾的测定》（LY/T 1234-2015）与《森林土壤磷的测定》（LY/T 1232-2015）。叶片样品采用硝酸-高氯酸湿消解法进行前处理，遵循《森林植物及枯落物中二氧化硅、铁、铝、钙、镁、钾、钠、磷、硫、锰、铜、锌总量的测定》（LY/T 1270-1999）。磷、钾含量采用电感耦合等离子体发射光谱仪（Inductively Coupled Plasma, ICP, Thermo Fisher iCAP 7400）测定。植物缩合单宁含量的测定遵循ISO 9648:1988《高粱 单宁含量的测定》标准，总酚类物质含量采用福林-酚法（Folin–Ciocalteu method）测定，参考方法源自Meda等人2005年的研究。
