Hydroponic Cultivation of Bibb Lettuce in Nitrogen Phosphorus Potassium (NPK)-Limited Conditions

This comprehensive dataset includes a variety of data types, data volumes, true replications, and pseudo replications of data collected as time-series data during the entire lifecycle for hydroponic lettuce cultivation experiments. This dataset contains large amounts of elemental analysis far beyond anything published previously in part for potential use in future research. Bibb lettuce (Lactuca sativa) was grown in vertical farm-wall style hydroponic systems, in controlled environment chambers at 21.5 Celsius and 50-70% relative humidity, and in multiple limiting nutrient conditions for Nitrogen, Phosphorus, and Potassium. For an additional level of in-depth detail, see methodology in referenced manuscript(s).This dataset includes 18 files. The 16 base files contain identical formatting, a significant amount of preliminary fundamental interpretation/manipulation (e.g., dividing "dry mass" by "fresh mass" to get "dry mass %"), and multiple worksheets (tabs) which summarize data on other worksheets. Anytime there is ambiguity or lack-of-understanding on what a cell means, it may be helpful to highlight a data cell in that column to see which other columns/cells it references and follow the chain of references. The first of the two remaining files is the workbook "NPK.YoungPlants.Screen" file, containing cross-treatment data on young plants. The final file is the workbook "NPK.CrossT.All" which references and summarizes all other workbooks in the dataset, and is useful for easy reference when analyzing data across all tabs.<br>

本综合数据集涵盖水培生菜栽培实验全生命周期内采集的多类型、多体量时序数据，包含真实重复与伪重复样本数据。本数据集包含海量元素分析数据，规模远超以往已发表成果，可用于未来相关研究工作。实验采用直立农场墙式水培系统，在温度21.5摄氏度、相对湿度50%-70%的可控环境舱内种植比布生菜（Bibb lettuce，学名Lactuca sativa），并设置氮、磷、钾多梯度限养条件。如需获取更深入的细节，请参阅参考文献中的实验方法部分。本数据集共包含18个文件。其中16个基础文件格式统一，包含大量预处理基础解析与操作内容（例如，通过干重（dry mass）除以鲜重（fresh mass）计算干重占比（dry mass %）），并设有多个汇总其他工作表数据的工作表（标签页）。若对某单元格的含义存在歧义或不解，可高亮该列中的数据单元格，查看其关联的其他列/单元格，并顺着引用链追溯以明确含义。剩余两个文件中的首个为工作簿"NPK.YoungPlants.Screen"，包含幼苗阶段的跨处理实验数据。最后一个文件为工作簿"NPK.CrossT.All"，该文件对数据集中所有其他工作簿进行了引用与汇总，便于在跨所有标签页开展数据分析时快速查阅。
