| Abstract: |
| The saline-alkali land area in China is vast and the secondary salinization problem is prominent. The situation of effective control and improvement of saline-alkali land is still severe. Based on the analysis of the literature on the application of subsurface drainage technology in saline-alkali soil treatment in the past 30 years, the application status and research progress of filter layer and layout parameters of subsurface drainage were systematically summarized. Based on the practical application, the problems was analyzed in the application and promotion of subsurface drainage technology. And put forward some suggestions for future research. |
