Mini-lysimeter Software

Development of more efficient and sustainable irrigation technology is critical to maintain horticultural production in a water scarce future. Sensor controlled irrigation is an emerging technology that has the potential to increase irrigation efficiency and reduce overwatering by using real-time data on container water status to control the timing and volume of irrigation events. This project presents a novel irrigation control system using lysimetry. We develop small scale lysimeters, referred to as mini-lysimeter, which provide a direct measure of actual evapotranspiration (ET) via a change in mass of containerized crops. This data repository provides the software necessary to calibrate and operate a mini-lysimeter controlled irrigation system using the hardware design documents found in this data repository (doi: 10.17632/825zc3xwz4.1)在未来水资源短缺的背景下，研发更高效且可持续的灌溉技术，对维持园艺生产至关重要。传感器控制灌溉是一项新兴技术，其通过实时采集容器内水分状态数据，调控灌溉作业的时机与灌溉量，有望提升灌溉效率并减少过度浇水问题。本项目提出了一种基于蒸渗仪法（lysimetry）的新型灌溉控制系统。我们研发了小型蒸渗仪，即微型蒸渗仪（mini-lysimeter），其可通过容器栽培作物的质量变化，直接测定实际蒸散量（actual evapotranspiration, ET）。本数据集仓库提供了校准与运行微型蒸渗仪控制灌溉系统所需的软件，相关硬件设计文档亦收录于本数据集仓库中（doi: 10.17632/825zc3xwz4.1）
