１９９３～１９９５年研究了５种不同模式水稻田生态系统水量平衡及水分效率结果表明，不同水稻田模式其总耗水量之间有明显差异，其中节水模式和节水节肥模式较常规模式节省灌溉水达１５～２３％，水分生产效率增加３０％以上．各模式蒸发蒸腾耗水量在同一生长季内基本相同．田间结构及调控管理对其无明显影响实测水稻生育期田间蒸发蒸腾量与计算的可能蒸发蒸腾量相差不过５％。
From 1993 to 1995, the water balance and water efficiency of five different paddy field ecosystems were studied. The results showed that the total water consumption of paddy field was significantly different among different paddy fields. Water saving mode and water saving mode were more effective than the conventional mode Irrigation water up to 15 ~ 23%, water production efficiency increased by 30% or more. The evapotranspiration of each mode was basically the same in the same growing season. Field structure and regulation and management had no significant effect on it. The measured field evapotranspiration during the growth period of rice was only 5% less than the calculated potential evapotranspiration.
