摘要
通过室内不同浓度氯化钠溶液的水平一维入渗试验,分析了氯化钠溶液浓度对水平一维入渗的湿润锋、累积入渗量、土壤含水量和土壤氯离子含量的影响。结果表明:增大氯化钠溶液浓度,减小了湿润锋、累积入渗量和土壤含水量,但增大了土壤中氯离子含量。以上研究成果为微咸水合理灌溉提供理论依据。
Through indoor experiment of different concentration solution of sodium chloride under one-dimension horizontal infiltration,the effect of concentration solution on wetting front,total infiltration volume,soil water content and chloride iron content is analyzed.The result shows that with the increase of concentration of sodium chloride,the wetting front,total infiltration volume and soil water content is decreased but the soil chloride iron content is increased.The research results provide theory base for the irrigation with saline water.
