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.
