一、农业节水的紧迫性我国水资源整体上短缺,而农业用水在水资源中所占的比重最大。随着国民经济快速增长,水资源“瓶颈”问题日益显现,如何解决这个问题,成为社会普遍关注的问题。从目前我国水资源供需状况来看,大量的农业水资源供给是不可能实现的。出路只有一条,提高水资源利用率,发展高效节水农业是必由之路。因此,农业节水已经成为国家安全的重要组成部分,具有紧迫性。 First, the urgency of agricultural water saving China’s overall shortage of water resources, agricultural water and water resources in the share of the largest. With the rapid growth of the national economy, the issue of “bottleneck” of water resources is becoming increasingly apparent. How to solve this problem has become a widespread concern in society.

Only one way out to improve water use efficiency, the development of efficient water-saving agriculture is the only way. Therefore, saving water in agriculture has become an important part of national security and it is urgent.
