摘要

水分作为植物光合作用、营养转运和叶片有效及时生长的重要基础成分的实现。本文提出了一种测定植物叶片电磁参数的新方法。详细讨论了电磁参数的测量结果。近距离观察发现,由于水分在叶片组织中的快速蒸发,新鲜叶片的介电常数和折射率在第1 ~ 4天的峰值均呈下降趋势,并且新鲜叶片和水分胁迫叶片的形态结构发生了变化。本文提出的技术可用于可行的、无创的植物叶片健康监测。

Electromagnetic Properties of Plant Leaves at Terahertz Frequencies for Health Status Monitoring
The realization of water as an important and fundamental component requires in photosynthesis, nutritional transport, and to the effective and timely growth of plant leaves. In this work, a novel technique has been presented to determine the electromagnetic parameters of plant leaves. The measurements results of electromagnetic parameters are discussed in detail. Upon a close observation, it has been found both permittivity and a refractive index of fresh leaves showed a decline trend in their peak values from day 1 to 4 due to the rapid evaporation of moisture in tissues of leaves, and variations occurred in the morphological structure of fresh and water-stressed leaves. The technique proposed here can be employed for feasible and non-invasive plant leaves health monitoring.
