Effects of Subsurface Pipe Drainage on Waterlogging Controlling and Desalination in Coastal Saline Soil
摘要
Abstract
Subsurface drainage plastic pipes were buried in typical coastal saline soil plots in Jiangsu Province with designed 1.2 m and 1.4 m depths and 10 m, 15 m and 20 m intervals. The effects of subsurface pipe drainage on groundwater depth controlling and desalination were mainly detected in the flooding season (from July to September). The groundwater depth was significantly reduced by subsurface pipes buried with 10 m interval. There was no significant difference between the treatments with 15 mand 10 m intervals. The effect of subsurface pipes buried with 1.4 m depth was better than 1.2 m depth with the 10 cm interval, but no significant difference was found between the effects of different buried depths with the buried interval ≥15 m. The effects of subsurface pipe with 1.4 m depth on desalination were more obvious than 1.2 m depths. Based on synthetical estimating the experimental results and constructing and maintaining costs, subsurface pipes buried with 15 m wide and 1.4 m depth were recommended as the optimal parameters for waterlogging controlling and desalination in coastal saline soil in Jiangsu Province.关键词
