Taking the agricultural water conservancy engineering in Zoucheng City of Shandong Province as an example,this paper introduces the basic situation of the engineering.Combined with the comparison of various irrigation technology schemes,the center pivot sprinkler system is finally determined,and the efficient water-saving irrigation system is designed.Based on this,the application effect of the system is verified.It can be seen from the verification that compared with the traditional irrigation technology,the center pivot sprinkler system can save more than 11%of the water consumption,which can be extended to the field of modern agricultural water conservancy engineering,use for reference.
