Effect of Kalidium foliatum Community on Soil Salinization
Over-exploration of underground water and unreasonable irrigation patterns lead to severe soil salinization in the Minqin Oasis at the downstream of the Shiyang River of China.Kalidium foliatum is the major halophytes and xeric community surviving in the area.We investigated the electricity conductivity (Ec) of soil and Kalidium foliatum samples to detect how the Kalidium foliatum affect soil salinity.Results showed that soil Ec increased with the distance from the Kalidium foliatum canopy,and the spatial difference mainly occurred in the surface soil layer (0-5 cm).Ec in the stem of Kalidium foliatum was higher than in root and leaves,which was similar to the Ec in 0-5 cm soil under canopy.Irons like Na+,Cl-and SO42-absorbed from the soil was mainly stored in the stem,whereas Mg2+ in leaves.
