| 摘 要： | 针对甘肃省疏勒河灌区粘土夹层土壤的阻水滞盐作用,提出了竖孔排盐改良技术。通过对不同层位的粘土夹层土壤的洗盐效果试验研究,分析了脱盐层厚度、计划脱盐层脱盐效率,提出了有效洗盐半径的概念、砂孔数量及孔径等设计参数,并制定相应的洗盐制度。

| Abstract: | According to the situation on back-salinity at clay interlayer in Gansu Shule River irrigation area,the improvement technology on drainage salinity through stand-hole was suggested to adopt in Shule River irrigation area.Based on the test of drainage salinity effect in different clay interlayer and the analsis of thickness of drainage salinity layer,the design parameter of effective drainage salinity semidiameter,amount of sand-hole and semidiameter of hole were put forword. |

| Keywords: | drainage salinity through stand-hole improvement of saline-alkali clay interlayer |
