摘　　要：水稻根系残留于土壤,是水稻土有机质来源的主要因素之一,也是水稻土有机碳含量保持一定稳定性的重要因素。本数据集来源于中国科学院桃源农业生态试验站长期监测样地,包括综合观测场、辅助观测场(3个施肥处理)、2个站区调查点样地2005–2018年相关数据。数据集由7个部分组成,分别是表层根系生物量(0–20 cm)、根系元素含量(全碳、全氮、全磷、全钾)、根系分布(0–10 cm、10–20 cm、20–30 cm、30–40 cm)、样地背景信息、样地肥料投入情况、采样记录、分析方法记录。数据的产生严格遵照CERN生物联网监测规范执行,数据质量由台站与分中心质控人员审核质控。本数据集为调查水稻根系对稻田土壤有机碳及氮磷钾元素的贡献,以及水稻根系对维护稻田土壤地力的作用提供可靠的基础数据。Rice root residue in soil is one of the primary contributor to the organic matter content in paddy soil,and it also plays an important role in maintaining the stability of organic carbon content in paddy soil.This dataset collects the rice root biomass in top soil and the root nutrient from 6 long-term monitoring plots(one comprehensive observation field,three complementary observation fields,namely 3 fertilization treatment sites,and two investigation stations)of Taoyuan Agroecological Experimental Station of Chinese Academy of Sciences from 2005 to 2018.The plots include The dataset consists of 7 parts:surface root biomass(0-20 cm),root nutrient content(including total carbon,total nitrogen,total phosphorus,total potassium),root distribution biomass(0-10 cm,10-20 cm,20-30 cm,30-40 cm),background information of the sample plots,fertilizer input in the sample plots,sampling records,and analysis method records.The generation of data is strictly in accordance with the CERN biological network monitoring specifications,and the data quality has been reviewed by quality control personnel from both from both the station and the subcenter.This dataset will provide reliable basic data for exploring the contribution of rice roots to soil organic carbon,nitrogen,phosphorus and potassium levels in paddy fields,as well as the role of rice roots in preserving soil fertility.
