Study on Dynamic and Non-destructive Ultrasonic Echo Detection Method of Plant Stem Water Content

摘要：

　　Stem water content is an important index of plant water balance.A new method based on changes in ultrasonic properties of stem was used to monitor stem water content in this paper,because the propagation of ultrasonic pulse echo signal and its attenuation characteristics in the material are closely related to the structure of the material.Ultrasound propagation echo signal was measured with an ultrasonic emission analysis system in the plant stem.The study showed that the increase of stem water content in the Populus simonii stem could cause the average amplitude,the root mean square (RMS) and the peak of value of the ultrasonic echo signal decreased obviously.The analysis of ultrasonic properties provides a new method for the detection of stem water content of trees and may be used to monitor plant water balance.
