摘  要：
为探索南方灌区不同区域尺度水稻灌溉定额的差异,在南方地区鄱阳湖流域选取典型区域,开展不同区域尺度水量平衡试验,研究水稻全生育期不同区域尺度的灌溉定额,为不同区域尺度农业水资源规划、调度、管理和评价提供科学依据。结果表明:不同区域尺度水稻灌溉定额存在一定差异,随着尺度增大,灌溉定额逐渐减少,灌区存在回归水的重复利用;区域尺度灌溉定额较灌溉试验站有底测坑减少173.3 mm,减少率为32.80%;较大田典型田块尺度减少143.2 mm,减少率为28.74%。在采用灌溉试验站试验数据或典型田块观测计算数据进行农田灌溉指导或灌溉工程规划设计时,要适当考虑试验限制条件和区域内回归水的重复利用。

摘  要：
In order to explore the differences of different regional scale rice irrigation quota, typical irrigation area is selected in the south Poyang lake basin in this paper to carry out different regional scale water balance test and study the rice irrigation quota at different regional scale in the whole stages to provide scientific basis for different regional scale agricultural water resources planning, scheduling, management, and evaluation. The results showed that there was a certain difference in rice irrigation quota between different regional scales; The regional scale irrigation quota decreased by 173.3 mm and 32.80% compared with the bottom-pit in the experimental irrigation station; Compared with the typical field block size, the reduction rate was 143.2 mm and 28.74 %.When using the experimental data of irrigation test station or the typical field observation and calculation data for the guidance of farmland irrigation or the planning and design of irrigation engineering, the limitation conditions of experiment and the reuse of regression water in the region should be properly considered.
