土壤水分运动对渗灌技术的影响研究

Study on the Influences of Soil Water Movement to Subsurface Irrigation Performance

采用数学模型对渗灌条件下不同的土质、初始含水率、渗管埋深、供水压力和历时的土壤水分运动进行计算分析 ,并研究其对渗灌技术的影响 ,提出了相关的设计参数。

With a mathematical model, soil water movement under subsurface irrigation was simulated with different soil characters, initial soil water content, pipe position, water pressure and duration of water supply. The influences of these factors to subsurface irrigation performance also are discussed and some relevant design parameters are presented in this paper. As a sample, the application of subsurface irrigation in vegetables in greenhouse is introduced.
