滨海盐土地区稻田暗管排水效果试验研究

Experiment and Research on Seepage Effect by Underground Pipe Drainage System of Paddy Field in Saline Soil Coastland

摘要: 稻田渗漏量是调节土壤通透性、降解土壤盐渍害的重要控制指标,涉及自然、经济技术等多种复杂因素,该文依据渗漏量对地下水溶解氧、土壤氧化还原电位、作物产量等的影响特点,通过3年的试验研究,首次提出滨海沙性盐土地区稻田渗漏量的上限控制指标,为该类地区暗管排水系统的规划设计及运行管理提供了参考

Abstract: Based on the influence of seepage rate on the dissolved oxygen in ground water, oxidation reduction, electric potential of soil and yields of plant from 3 years' field experiments and researches, this paper put forward the upper controlling index of seepage rate for paddy field in sandy saline soil region by the sea, which is of substantial practical significance to the region in the plan, design operation and management of underground drainage system.
