摘要
通过大量膜孔单向交汇入渗试验资料,分析了膜孔单向交汇入渗湿润体特性的主要影响因素,研究了膜孔直径、间距、土壤容重、土壤质地和土壤初始含水率对膜孔单向交汇入渗的影响,结果表明各因素对膜孔单向交汇入渗湿润体特性均有明显的影响。这些研究成果为进一步研究膜孔单向交汇入渗规律和膜孔灌技术奠定了基础。
The authors analyzed influential factors of wetting soil characteristic under film hole singleline interference infiltration by using a great deal of the experiment data.The main influential factors such as film hole area,film hole space,soil density, soil texture and antecedent soil moisture content were studied.It was revealed that these influential factors had a great effect on film hole singleline interference infiltration.The results laid a foundation for further research of film hole singleline interference infiltration law and film hole irrigation technology.
