Raw data and source code for: A lettuce growth model responding to a broad range of greenhouse climates
收藏资源简介：
The raw data and model program supporting the manuscript entitled ‘A lettuce growth model responding to large scale greenhouse climate’ are shared here. 1. Datasets To obtain data for calibration and validation of the lettuce growth model, three experiments of greenhouse lettuce cultivation were carried out. The experiment performed in the cold season was used for global calibration and named the calibration experiment (Exp_c). The other two in warm and cold-warm seasons, namely the first validation experiment (Exp_v1) and the second validation experiment (Exp_v2), were used for model validation. The data of each experiment is stored separately in the .xlsx file below. Greenhouse Climate & Crop data_Exp_c: Greenhouse climate and lettuce growth states in Exp_c. Greenhouse Climate & Crop data_Exp_v1: Greenhouse climate and lettuce growth states in Exp_v1. Greenhouse Climate & Crop data_Exp_v2: Greenhouse climate and lettuce growth states in Exp_v2. These three .xlsx files have the same structure, including the sheets of Greenhouse climate, Lettuce growth, Lettuce growth summary, Lettuce growth summary_Sim, SLA calibration, and Root ratio. One exception is that the ‘Greenhouse Climate & Crop data_Exp_v1’ file contains an additional sheet named ‘Lettuce growth_TOP12’. The specific contents included in each sheet are illustrated as follows: Greenhouse climate: Greenhouse climate measurements, which are used as model inputs. Lettuce growth: The lettuce growth states measured in the laboratory, covering all the sampled plants in every sampling. Lettuce growth_TOP12: The lettuce growth states measured in the laboratory, covering the top 12 of the 18 lettuce samples in crop dry weight in every sampling. This sheet is derived from the sheet of ‘Lettuce growth’. Lettuce growth summary: Averages of the lettuce growth states, including crop dry weight and leaf area index that are determined by unit conversion according to plant density. This sheet is derived from ‘Lettuce growth’ or ‘Lettuce growth_TOP12’. Lettuce growth summary_Sim: Averages of the lettuce growth states used for global calibration and validation simulations. This sheet is derived from ‘Lettuce growth summary’. SLA calibration: The data used for calibrating the sub-model that describes the specific leaf area of new leaves. This sheet is derived from ‘Lettuce growth summary_Sim’ and ‘Greenhouse climate’. Root ratio: The data used for root ratio sub-model calibration. This sheet is derived from ‘Lettuce growth summary’. 2. Code The source code of the lettuce growth model is in MATLAB format. The ‘Lettuce growth model program’ folder contains a script m-file, eight function m-files, and a data file in .xlsx format. The inputs of this code template are from Exp_v2. The principle of programming is to simplify the code and improve the computational efficiency. The source code of the smoothed model is also presented.
本数据集共享了支持题为《响应大规模温室气候的生菜生长模型》论文的原始数据与模型程序。 1. 数据集 为获取生菜生长模型校准与验证所需数据，本研究开展了3批温室生菜栽培试验。其中冷季开展的试验用于模型全局校准，命名为校准试验（Exp_c）；暖季与冷暖交替季开展的另外两批试验分别为第一验证试验（Exp_v1）与第二验证试验（Exp_v2），用于模型验证。各试验的数据分别存储于下述.xlsx文件中： Greenhouse Climate & Crop data_Exp_c：校准试验（Exp_c）的温室环境与生菜生长状态数据。 Greenhouse Climate & Crop data_Exp_v1：第一验证试验（Exp_v1）的温室环境与生菜生长状态数据。 Greenhouse Climate & Crop data_Exp_v2：第二验证试验（Exp_v2）的温室环境与生菜生长状态数据。 上述3个.xlsx文件结构一致，均包含以下工作表：'Greenhouse climate'、'Lettuce growth'、'Lettuce growth summary'、'Lettuce growth summary_Sim'、'SLA calibration'与'Root ratio'。其中'Greenhouse Climate & Crop data_Exp_v1'文件额外包含1个名为'Lettuce growth_TOP12'的工作表。各工作表的具体内容说明如下： 'Greenhouse climate'：实测的温室环境数据，作为模型输入项。 'Lettuce growth'：实验室测定的生菜生长状态数据，涵盖每次采样的全部供试植株。 'Lettuce growth_TOP12'：实验室测定的生菜生长状态数据，选取每次采样中18份生菜样本内作物干重排名前12的植株数据。该工作表源自'Lettuce growth'工作表。 'Lettuce growth summary'：生菜生长状态的平均值数据，包含按植株密度进行单位换算得到的作物干重与叶面积指数。该工作表源自'Lettuce growth'或'Lettuce growth_TOP12'工作表。 'Lettuce growth summary_Sim'：用于模型全局校准与验证模拟的生菜生长状态平均值数据。该工作表源自'Lettuce growth summary'工作表。 'SLA calibration'（比叶面积，Specific Leaf Area）：用于校准新生叶片比叶面积子模型的数据。该工作表源自'Lettuce growth summary_Sim'与'Greenhouse climate'工作表。 'Root ratio'：用于校准根干重比率子模型的数据。该工作表源自'Lettuce growth summary'工作表。 2. 代码 生菜生长模型的源代码采用MATLAB格式编写。'Lettuce growth model program'文件夹包含1个脚本m文件、8个函数m文件以及1个.xlsx格式的数据文件。该代码模板的输入数据源自Exp_v2。代码编写原则为简化代码结构并提升计算效率。 本数据集同时提供了平滑化模型的源代码。
