Note:a,chloride saline(Cl–saline)was a mixture of Ca Cl2+Na Cl.b,mixed saline(Cl–/SO42–saline)was a mixture of Ca Cl2 and Na2SO4.c,values represent mean±SD(n=3).

The influences of both Cl–and mixed Cl–/SO42–salts on soil EC are given in Table 2.The average EC was 0.16 d S/m in the control.This falls well under the standard threshold for saline soils(EC of the saturation soil extract>4 d S/m at 25°C).The addition of either Cl–or mixed Cl–/SO42–salt highly increased soil EC.
