摘要

对太湖地区主要水稻土类型的饱和导水率进行了研究。结果表明

该土壤的饱和导水率变化于 7.20×10

-5

～6.33×10

-4

cm/s

并随着深度的增加饱和导水率迅速下降;原状土和扰动土的饱和导水率相差很大

土壤的质地、有机质含量、容重、孔隙度和结构系数等均对饱和导水率有一定的影响。原状土的饱和导水率能反映田间的实际情况

对研究土壤水分平衡和水土保持有极其重要的意义。而扰动土的饱和导水率只能作为一种农业工程的参考数据被运用。

Abstract

The saturated hydraulic conductiv it ies of mainly paddy soil in Taihu lake region were studied. The results were as follows. (1) The saturated hydraulic conductivities in the soil were changeable from 7.20×10-5 to 6. 33×10-4 cm/ s and decreased with the increasing of soil depth.(2) The saturated hydraulic conductiv it ies of undistur bed soil and distur bed soil were quite different and affected by soil texture

organic matter content

bulk density

porosity and structural index. The saturated hydraulic conductivity of undisturbed soil can represent the really case in the field and is significant to study soil moisture balance and soil water conservation. But the saturated hydraulic conductivity of disturbed soil can only be used for a reference information in agricultural engineering.
