Analysis And Discussion On The Development Of High-efficiency Water-saving Irrigation In Dry Fields In Yangshu Town, Acheng District

Yangshu Town in Acheng District is a township with agriculture as its main economic income.Yangshu Town has a shortage of surface water resources,arid drought in spring,and weak agricultural infrastructure.The main crop is corn.This paper takes Yangshu Town of Acheng District as an example.Based on the comparison of high-efficiency water-saving irrigation,this paper studies the advantages and disadvantages of several methods of time-type sprinkler,reel-type sprinkler and sub-drip drip irrigation in Yangshu Town,Acheng District,and then extends to highefficiency water-saving irrigation.The development analysis explores the model suitable for the development of high-efficiency water-saving irrigation in Yangshu Town,breaks the bottleneck restricting agricultural development,and discusses some problems in the development of high-efficiency water-saving irrigation.Through data literature search,field understanding,data comparison and other methods,the first is to understand the evolution and current status of high-efficiency water-saving irrigation.The second is to compare and analyze several high-efficiency water-saving irrigation modes.The third is to analyze the development of highefficiency water-saving irrigation in Yangshu Town.The main results achieved are as follows:1.Using the previous literature,analyze and study the agricultural structure,grain production,irrigation pattern,irrigation quota,irrigation water,etc.in the study area.The agriculture in Yangshu Town of Acheng District is mainly based on corn cultivation.The total area of dry land is 114,000 mu,and the current water-saving irrigation area is 28,000 mu.The development potential of water-saving irrigation is great.2.Analyze several high-efficiency water-saving irrigation modes in Yangshu Town,and analyze the characteristics,shortcomings and applicability of several highefficiency water-saving irrigation modes in combination with local construction.Through analysis and comparison,the current use of farmers is the most recognized.It is a reel type sprinkler.3.Take Yangshu Town as an example to analyze the development of highefficiency water-saving irrigation.Efficient water-saving irrigation has an obvious increase in grain production,and the effect of irrigation water conservation is remarkable.There are problems such as single fund channels,slow development of scale,and indistinct increase in farmers' income.
