由美国犹他州立大学提供。主要由植物培养容器、悬挂式称量微型传感器、灌水自动控制及数据采集系统组成。最大称重100kg，精度可达0.25g.Kg-1。可最小30分钟测定1次，补水量根据植物蒸腾水散失量设定，可通过互联网远程访问、控制仪器。该系统可为植物抗旱性和水分利用效率研究提供稳定的环境条件，可连续监测和精确地掌握植物不同时间/时期的需水、耗水规律，为精准灌溉提供可靠理论依据。
系统现从事枣树需水规律研究，为枣树的精准灌溉提供可靠的理论依据，促进陕北部分地区红枣主导产业的发展。
The Continuous Measuring and Automatic Supply System for Plant Water Consumption
This system, provided by the Utah State University in theU.S.A., is mainly composed of the plant incubation vessels, hanging weighing micro-sensors, automatic water supply unit, and data harvesting component. It can provide stable environmental conditions for the studies on plant drought resistance and water use efficiency. The system is now being used to study the water requirement and precision irrigation of Chinese Jujube ( Ziziphus jujuba Mill ) trees, which is believed to promote the development of Chinese date industry in specific areas of Northern Shaanxi of China.
