咸水灌溉对盐渍化土壤有机碳和无机碳的影响
Effects of Saline Water Irrigation on Salinization Soil Organic and Inorganic Carbon
摘要
Abstract
Carbon conversion is one of the hot-point issues to address climate change, and an important compo-nent of global carbon budgets.[Objective]Explore the significance of soil carbon processes and enhance devel-opment of strategies to establish and the calculate carbon storage.[Method]The object of study was differed with soil textures, they were loam (A), clay loam (B), silty clay loam (C) and sand loam (D), respectively. A simu-lation experiment was conducted to study the effects of salt solution (NaCl, Na2SO4) with different mineraliza-tions (0, 2, 4, 6g/L) on soil organic carbon and inorganic carbon.[Result]There were significant differences in soil salt, organic carbon and inorganic carbon for irrigating the different mineralization degree of NaCl and Na2SO4 solution in the four soil textures.[Conclusion]There were extremely significant differences in soil organ-ic carbon (p<0.01) between loam (A) and silty clay loam (C), and between clay loam (B) and sand loam (D), re-spectively. There were significant differences in soil organic carbon (p<0.05) between clay loam (B) and sand loam (D).Soil inorganic carbon had extremely significant differences(p<0.01)between loam (A), clay loam (B), silty clay loam (C) and sand loam (D), respectively.关键词
