对水田优化灌溉制度的研究,是为了有计划的开发利用水资源,不同水文年所采用的灌溉制度,使之在农田供水总量一定的条件下获得最大的收益,并从过去充分满足水稻淹灌用水的旧概念中走出来,因地制宜地解决灌溉制度经济优化问题。目前,由于水田面积不断扩大,灌溉缺水矛盾更加尖锐,研究节水型农田灌溉技术,
The research on the optimized irrigation system in paddy fields is intended for the planned development and utilization of water resources and the irrigation system adopted in different years of hydrology, so as to obtain the maximum benefit under the condition of a certain amount of farmland water supply and fully satisfy the flooding of rice from the past The old concept of irrigation water came out to solve the economic optimization of irrigation systems according to local conditions. At present, due to the continuous expansion of the paddy field, the contradiction between irrigation and water scarcity is even more acute. To study the water-saving irrigation techniques,
