摘　　要：我国目前水稻的主要栽培方式是育苗移栽。水稻育苗期间的需水量很少,故一般水稻的需水量主要指移栽后该田间的蒸腾量。文章主要以水稻淹灌、水稻浅湿灌实验资料对比,对水稻在不同灌溉方式下的水稻需水量和需水规律进行分析。同时对优化灌溉模式、节水灌溉及对水资源评价的意义提出了建设性建议。At present, the seedling transplantation is the main cultivation pattern of the rice in China. Based on the little water requirement during the rice seedling, the water consumption of the rice is usually the field transpiration after the transplantation. Comparing the experimental data of the rice deep water irrigation and rice shallow wet irrigation, the paper analyzes the rice water requirement and the requirement regular under the different irrigation ways, which propose the constructive suggestions for the optimizing irrigation patterns, water-saving irrigation and the significance of the water resources assessment.
