- Abstract:
-
The soil properties and soil enzyme activities in saline-alkali land of the Yinchuan Plain were studied after the soil was improved with straw, organic fertilizer, flue gas desulfurization waste and saline-alkali soil conditioner. The results showed that four measures reduced soil pH, total salt content and soil bulk density to some extent, flue gas desulfurization waste and saline-alkali soil conditioner significantly reduced soil pH and total salt content, saline-alkali soil conditioner and organic fertilizer reduced soil bulk density and increased soil porosity remarkably. The improvement measures significantly increased soil invertase activity, urease and alkaline phosphatase activity after improvement, the increase rates were 0.02%~85.0%, 2.7%~53.3%, 17.9%~49.7%, respectively. The effect of the improvement measures on change of catalase activity was not significant. There was a positive correlation relationship(p<0.05) among soil pH, total salt content and soil bulk density, and soil porosity had a negative correlation relationship with soil pH, total salt content(p<0.05). There was a negative correlation relationship(p<0.05) among soil bulk density and soil porosity, hydrogen peroxide enzyme, urease activity. There was a positive correlation relationship(p<0.05) among soil alkaline phosphatase, invertase, catalase and urease activity.
