摘要
由于全球水资源短缺 ,节水灌溉已经越来越引起人们的重视。地下滴灌系统是很重要的一种节水灌溉系统 ,有其显著的优点 ,也存在许多缺点。该文对其发展历史、对作物产量的影响、目前研究热点、系统设计和管理、灌溉制度的拟定、施肥灌溉、环境及经济分析、系统的优缺点等进行了综述性讨论。
Water saving in agriculture becomes more and more urgent task in the world due to the shortage of global water resources. Subsurface drip irrigation (SDI) is one of the water saving irrigation system, with its obvious advantages and some disadvantages. The paper discusses development of SDI, its effect on crop yield, research focus, system design and management, irrigation scheduling, fertigation, analysis of environment and economics, advantage and disadvantages of SDI system, etc. It will be helpful for development of SDI technology in China.
