摘　　要：结合灌溉不易建立精确的数学模型和模糊控制决策不需要建立精确数学模型的特点,应用模糊逻辑设计了以AT89C51为核心的全自动模糊智能节水灌溉控制器,该控制器能根据检测到的土壤含水量和作物的需水情况进行模糊决策从而实现全自动智能灌溉。系统已经成功运行于曲阜示范区,收到了较好的经济和社会效益。In order to solve the problem of agricultural water-saving irrigation,use fuzzy logic to design the full-automatic fuzzy intelligent water-saving irrigation controller which takes AT89C51 as the core, considering that modeling precise mathematic model for irrigation is difficult and fuzzy control does not need precise model. The controller can go on fuzzy decision on the basis of soil water content and crop demand for water, and thus realize full-automatic intelligent irrigation. This system has been succeeded in operating in the Qufu demonstration area and has received quite good effect.
