摘要

粮食安全是关系国计民生的重要保障，是关系经济发展、社会稳定和国家自立的基础。义县水资源比较短缺，已成为制约粮食增产的瓶颈，节水增粮行动以粮食生产区为重点，集中连片大规模推广高效节水灌溉技术，将大大提高粮食综合生产能力和农业灌溉水利用系数，实现节水增粮的有效目的。文章以义县2013年节水增粮项目为例，分析了玉米管灌的典型设计过程，以期对适合地区择情推广。%Food security is an important guarantee of the people's livelihood,is the basis of the relationship between economic development,social stability and national self-reliance.There is a water resources shortage in Yi County;it has become a bottleneck restricting the increase of grain yield.Water saving and increasing grain action in grain production area is to promote efficient water-saving irrigation technology in the concentrated and large extensive area,it will greatly improve the comprehensive grain production capacity and utilization coefficient of agricultural irrigation water,realizing the purpose of water-saving and grain increase.Taking water-saving and increasing grain project as an example in Yi County in 2013,the typical design process of corn irrigation is analyzed in order to popularize the technology in the areas suitable for promotion in this paper.
