The Research of Plants' Water Stress Acoustic Emission Signal Processing Methods

Water stress is the most common environmental threat that affects plants growing, so the diagnosis of water deficit is important and reasonable for plants' irrigation and feature recognition. For plants, there are ecological and physiological regulatory mechanisms to adapt to water stress of soil, and to survive in adverse growing environment, which provides a signal and basis for diagnosis of water deficit. It has an important significance for plants' reasonable irrigation to study plants' water stress acoustic emission (referred to as AE) signal. The main purpose of the study is to establish plants' water stress AE signal processing and analysis methods based on wavelet analysis, so as to lay a foundation for accurately grasping the plants' water deficit information, achieving automatic detection of plants' water stress and reasonable irrigation.
