| 摘 要： | 通过室内不同钠/钙离子比例土壤的水平一维入渗试验，分析了土壤中钠/钙离子比例对水平一维入渗特性的影响。结果表明：随着土壤中钠/钙离子比例的减小，相同入渗时间，土壤的湿润锋、累积入渗量、入渗率增大，入渗结束后，相同湿润深度的土壤含水量增大。以上研究成果为盐碱地合理灌溉，保持水盐平衡提供理论基础。

| Abstract: | In order to provide theory proof for irrigating on saline-alkali soil and maintaining water and salt balance,the effect of ratio of Na＋/Ca2 ＋ on infiltration characteristic is analyzed through indoor experiment of different ratio of Na＋/Ca2＋ under one-dimension horizontal infiltration.The result shows：with the ratio of Na＋/Ca2＋ decreasing,soil wetting front,total infiltration volume and infiltration ratio increases.After infiltration,the soil water content increase in the same distance with the ratio of Na＋/Ca2＋ decreasing.The research results provide |
