摘　　要：水是农业生产的命脉,但我国目前农业中的水利用率却很低,水胁迫声发射监测系统的研究是实施视情自动灌溉提高水利用效率的重要途径之一。为此,通过AE检测系统来采集植物的生理信息,以DSP为核心对声发射信号进行监测和实时信号处理,然后对数据进行存储、输出以及查询,实现系统的自动控制。本系统可实施自动灌溉或定时灌溉,提高了水的利用率,并且促进了农业生产管理的自动化。Water is the life-line of agriculture, but the water utilization ratio is very low at the present time in our country. The research of monitoring system of crop water stress is one of the paths to increase of water-saving efficiency by executing automatic irrigation according to the practical situation .This design can gather plant physiological information through AE detection system, monitor and treat sound emission signals using DSP as the core, then storageand output and inquiry data, in order to fulfill auto control. This system can implement auto or timing irrigation, improve the water utilization ratio, and accelerate the automata of agriculture production control.
