农业多样化是亚洲以水稻为基础的系统的一个主要趋势。然而，在低地，土壤和水条件大多适合水稻种植，通常需要开发凸起的床来容纳蔬菜或果树。在圩田层面（在地块和水渠之间）和地块层面（河床灌溉），抬升河床系统与具体的水管理技术相结合。本文详细介绍了湄南河三角洲对三种不同作物的管理：芒果、葡萄和芦笋，并解释了它们之间的差异。一年内的水量平衡，显示渗水的影响及估计需水量。水质被证明是一个主要问题。
Agricultural diversification is a major trend in Asian rice-based systems. In lowlands, however, soil and water conditions are mostly suitable for rice cultivation and the development of raised beds is often required to accommodate vegetables or fruit trees. Raised bed systems go together with specific techniques of water management, both at the polder level (between the plots and the canals) and at the plot level (bed irrigation). Details of this management in the Chao Phraya Delta are given for three different crops: mango, grapes and asparagus and differences are explained. The water balance over 1 year is specified, showing the impact of seepage and estimating water requirements. Water quality is shown to be a major issue.
