英文摘要	In soil, plant polyphenolics can affect nutrient dynamics and mobility of metals, but their role in saline-alkali soil is largely unknown. The present study aimed to understand the effects of polyphenolics on the salt ion content of Tamarix chinensis community and bare land soils in the Yellow River Delta. The effect of polyphenolics on salt ion availability in saline and alkaline soil was determined by selecting the native T. chinensis community and bare land soils as low and high salt content soils, respectively. Different concentrations of tannic acid (TA) were added to the soils, and then their salt ion composition and contents were analyzed. Differences in the cation and anion contents and ratios among different treatments were analyzed using analysis of variance and multiple comparisons. Correlation analysis was also used to determine the relationships among different salt ions in the soils having varied salt content. The results showed that TA strongly increased the extraction of salt ions, K~+, Ca~(2+), HCO_3~-, and Cl~-, from soils with high salt level and SO_4~(2-) from soils with low salt level; nevertheless, Na~+, Mg~(2+), and Cl~- concentrations in soils with low salt level and SO_4~(2-) concentration in soils with high salt level first increased and then decreased with increasing TA concentration. The Na~+/K~+, Na~+/Ca~(2+), Ca~(2+)/K~+, Mg~(2+)/K~+, Cl~-/HCO_3~-, SO_4~(2-)/HCO_3~-, and Cl~-/SO_4~(2-) in soils of low salt levels decreased with increasing TA, but Na`+/Mg~(2+), Ca~(2+)/Mg~(2+), and Cl~-/SO_4~(2-) in soils of high salt levels increased continuously. In soils of high salt level, TA had no effect on Na+, but had a significant effect on other salt ions. The relationships between SO_4~(2-) and K~+, Na~+, Mg~(2+), and HCO_3~- were contradictory in low and high salt content soils. However, the correlations among other salt ions were consistent in soils having different salt contents. The results indicated that TA led to the disassociation of salt ions from exchange sites in soils and facilitated the leaching of salt from the saline-alkali soils. Therefore, TA could be used as a soil amendment to ameliorate saline-alkali soil. However, the amount of TA needs to be appropriate to accelerate the leaching of Na+ and avoid the erosion of Ca~(2+) and K~+.
