提出了通过测量太赫兹波段树干反射率来监测葡萄树水分状况。葡萄藤位于生长室内，可模拟不同的室外条件，并将其与树干反射信号产生的变化相关联。葡萄树的光照条件、温度和灌溉的变化可以通过时域宽带测量以及频域窄带测量的幅度和相位来记录。结果与使用树木计和湿度探头的传统技术进行了比较，具有极好的一致性。
Monitoring grapevine water status by means of measuring the reflectivity at the trunk in the terahertz band is presented. A grapevine is located inside a growth chamber to simulate diverse outdoor conditions and correlate them with variations produced in the reflected signal of the trunk. Modifications of light conditions, temperature, and irrigation of the grapevine are recorded either in time domain broadband measurements as well as in the magnitude and phase of narrowband measurements in the frequency domain. The results are compared with traditional techniques using a dendrometer and a humidity probe with excellent agreement.
