This study aimed to analyze the variation of soil physical and hydrodynamic properties of saline soil with different salinization levels
the experimental study was carried out in Xuwei New Area of Lianyungang City
Jiangsu Province. Five kinds of soils with different salinization levels were sampled and their pH
ECe
bulk density
total porosity
water content and saturated hydraulic conductivity were measured. The changes of physicochemical parameters and hydrodynamic properties of coastal saline soils with different salinization levels were analyzed. The results showed that: (1) The soil ECe of 0—50 cm profile of different saline soils first decreased and then increased
but the ECe of 40—50 cm profile was larger than that of 0—10 cm profile. The changes of soil ECe in 0—50 cm profile of non-saline soil and extremely heavy saline soil were small
and the ECe value of 0—50 cm section of light saline soil
medium saline soil and heavy saline soil fluctuated greatly. (2) Soil ECe was negatively correlated with bulk density
and positively correlated with capillary porosity
non-capillary porosity
total porosity
moisture content
capillary water capacity
field water capacity and maximum water capacity. There was a very significant positive correlation between soil porosity and water holding capacity. (3) The saturated hydraulic conductivity of extremely heavy saline soil was significantly lower than that of other saline soils
and the saturated hydraulic conductivity of 0—20 cm profile was greater than that of 20—50 cm profile. The results could provide a theoretical reference for water and salt management and ecological environment construction of coastal saline soil.
