容重对不同有机质含量土壤水分入渗特性的影响
Influence of Soil Bulk Density on Soil Water Infiltration Characteristics Under Different Soil Organic Matter Contents
摘要
Abstract
Soil water infiltration characteristics under different soil organic matter contents were researched based on experimental data of infiltration under different soil bulk densities.The results indicated that soil bulk density had different influencing degree on the same soil texture with different soil organic matter content.The influence was obvious on soil with high soil organic matter content,soil accumulative infiltration volume and the wetting depth decreased significantly,stable infiltration rate reduced quickly like a power function with increasing soil bulk density.Soil with low soil organic matter content was affected lower,soil accumulative infiltration volume and the wetting depth slightly decreased with increasing soil bulk density,stable infiltration rate reduced slowly like a linear function.The calculating results of soil saturated hydraulic conductivity by using Green-Ampt model and Philip model agreed with experimental ones under different soil organic matter content and bulk density.关键词
