地下滴灌可直接向作物根部供水，其水分利用效率较高，具有明显的节水增产效果。但存在系统能耗高、以塑料材质为主的地下滴灌带和灌水器难以回收和降解进而带来环境污染和土壤退化等问题，成为制约其大面积推广应用的主要因素。为此，本项目借鉴古代陶罐灌溉经验，创新性将微孔陶瓷材料引入灌水器研发中，以材料科学为基础，重点分析原料配方和制备工艺对微观形貌、开口孔隙率、连通度和孔径分布等微孔陶瓷材料性能的影响，建立材料性能与原料配方、制备工艺之间的定量数学关系；并通过理论分析、试验研究和数值模拟相结合的方法，构建不同结构参数下微孔陶瓷灌水器出流量计算模型，揭示微孔陶瓷灌水器水力性能对材料性能关键参数（孔隙特征）的响应关系；基于此，以灌水器水力和材料性能优良、造价低廉和制造偏差最小为目标，最终提出微孔陶瓷灌水器的规范化制备方法，为微孔陶瓷灌水器的应用提供理论与技术基础。

Subsurface drip irrigation can supply water directly to crop roots, which has high water use efficiency, obvious water saving and stimulation effects. However, problems such as high system energy consumption, environmental pollution and soil degradation issues caused by the plastic tape and emitter are of difficult degradation and recycling. The above problems are main factors of restricting the large-scale popularization and application of subsurface drip irrigation. Therefore, the project draws on the experience of ancient pottery irrigation, innovatively bring micro porous ceramic materials into the emitter research and development. In this project, emphases is put on the impact of the material formulation and preparation process on the microscopic morphology, open porosity, connectivity and pore size distribution of micro porous ceramic materials. In this way, to establish the quantitative mathematical relationship between material formulation and preparation process and construct the calculation model of the flow rate of micro porous ceramic emitter under different structural parameters combining theoretical analysis, experimental research and numerical simulation, in order to reveal the response between the hydraulic performance of the key parameters (Pore characteristics) and the material properties. Based on the above, with the goal of excellent performance of emitter, low cost and minimum manufacturing deviation, finally put forward the standardized preparation methods of porous ceramic emitters, so as to provide the theoretical and technological evidence for the application of porous ceramic emitter.
