摘要
以冬小麦田冬春季跟踪入渗试验为依据，揭示了冻融土壤水分入渗的基本特性；分析讨论了土壤累积入渗量、稳定入渗率在土壤冻结和解冻过程中的变化规律，并将薄层霜状冻层对土壤入渗特性的影响进行了讨论。其研究结论对于土壤水分入渗的研究和冬春灌溉灌水效果的研究具有理论意义，对冬春灌溉的用水管理具有实际意义。
Based on the soil infiltration experiments in wheat field within winter and spring seasons, this paper reveals the basic infiltrating characteristics of freezing and thawing soil, analyses and discusses accumulated infiltration amount and stable infiltration rate in freezing and thawing processes of soil and the influences of thin soil-frozen clay on soil infiltration characteristics. These results have theoretical value for the study of soil water infiltration and the study of irrigation effects, and have practical value for the water-used within winter and spring seasons.
