Abstract:
The plantations of Sophora japonica and Robinia pseudoacacia planted for 6 years (seedling age of 3 years) in coastal saline-alkali soil were studied，and their soil physical and chemical properties were compared in different seasons.The results showed that the different plantations had different improvement effect on the saline-alkali soil in different season,in the autumn，the soil bulk density of the plantations of Sophora japonica and Robinia pseudoacacia was decreased significantly by 23.40% and 14.20%，and the total porosity was increased significantly by 36.94% and 23.39%，the ratio of desalinization was respectively 66.51% and 44.29%，the contents of Cl-，Ca2+ and Na+in the soil of plantation of Sophora japonica was decreased significantly by 50.00%，51.85% and 41.76%，the content of Cl-in the soil of plantation of Robinia pseudoacacia was decreased significantly by 33.33%.In the word，the improvement effect of Sophora japonica on physical and chemical properties in saline-alkali was better than those of Robinia pseudoacacia in autumn.In the spring，compared with the control，the difference of the soil bulk density and total porosity of two plantations was not significant，the soil pH value and soluble salt content of the plantation of Robinia pseudoacacia were decreased significantly by 0.47 unit and 52.48%，and the contents of Ca2+，K+，Na+ was also decreased significantly，but the difference of content of other ions was not significant；the soil pH value of the plantations of Sophora japonica was increased significantly by 0.27 unit，the difference of the soil soluble salt content was not significant，and the contents of Ca2+，K+ were decreased significantly，but the difference of content of other ions was not significant.In short，the improvement effect of Robinia pseudoacacia on physical and chemical properties in saline-alkali soil was better than those of Sophora japonica in spring.But whether it was spring or autumn，the improvement effect of Sophora japonica and Robinia pseudoacacia on moisture content and organic matter in saline-alkali soil was not significant.
