Improved understanding of crops' response to soil water stress is important to advance soil-plant system models and to support crop breeding, crop and varietal selection, and management decisions to minimize negative impacts. Studies on eco-physiological crop characteristics from leaf to canopy for different soil water conditions and crops are often carried out at controlled conditions. In-field measurements under realistic field conditions and data of plant water potential, its links with CO and HO gas fluxes, and crop growth processes are rare. Here, we presented a comprehensive data set collected from leaf to canopy using sophisticated and comprehensive sensing techniques (leaf chlorophyll, stomatal conductance and photosynthesis, canopy CO exchange, sap flow, and canopy temperature) including detailed crop growth characteristics based on destructive methods (crop height, leaf area index, aboveground biomass, and yield). Data were acquired under field conditions with contrasting soil types, water treatments, and different cultivars of wheat and maize. The data from 2016 up to now will be made available for studying soil/water-plant relations and improving soil-plant-atmospheric continuum models.
提高对作物土壤水分胁迫响应的理解对于推进土壤-植物系统模型以及支持作物育种、作物和品种选择以及管理决策以最小化负面影响非常重要。通常在受控条件下进行针对不同土壤水分条件和作物的叶片到冠层的生态生理作物特性研究。在现实田间条件下进行田间测量以及植物水势、其与 CO 和 HO 气体通量及其作物生长过程的关系的数据很少。在这里，我们使用复杂而全面的传感技术（叶片叶绿素、气孔导度和光合作用、冠层 CO 交换、液流和冠层温度）从叶片到冠层收集了一套综合数据集，包括基于破坏性方法的详细作物生长特性（作物高度、叶面积指数、地上生物量和产量）。在具有不同土壤类型、水分处理和不同小麦和玉米品种的田间条件下获取数据。从 2016 年至今的数据将可用于研究土壤/水分-植物关系和改进土壤-植物-大气连续体模型。
