This paper investigated fabric coverings, exploring their ability to remove salt from saline soils. Soil columns filled with saline soil were saturated with saltwater, then covered with four kinds of fabric materials (nylon, cotton, geotextile [150 g m⁻²], and gauze). The soil columns were heated under infrared lights for 25 days. The microstructural characteristics of the fabric materials before and after the experiments, as well as the crystallization conditions on the soil surface, were examined using scanning electron microscope (SEM). The results demonstrated that both hydrophilicity and structure of fabrics affect salt removal efficiency. Although salt quantity removed by geotextile (111.54 g m⁻²) was less than gauze (293.89 g m⁻²), geotextile showed greater potential on salt removal considering long‐term evaporation. To further investigate the performance of geotextile material on salt removal, the experiment was repeated with commercially available geotextiles with areal densities of 200, 300, 400, and 500 g m⁻². The 500 g m⁻² geotextile could remove 368.15 g m⁻² of salt, much more than salt removed with geotextiles of density 150, 200, 300, and 400 g m⁻² (111.54, 61.57, 102.05, and 102.34 g m⁻², respectively), which further proved that fabric structure had great influence on salt removal. These results demonstrated that geotextile covering with optimized fabric structure could be a promising and environmentally friendly technique for farmland salinization control.

土工布覆盖：农田盐渍化控制的潜在技术

本文研究了织物覆盖物，探讨了它们从盐渍土壤中去除盐分的能力。充满盐渍土壤的土壤柱被盐水饱和，然后覆盖四种织物材料（尼龙，棉，土工布[150 g m ^-2 ]和纱布）。将土壤柱在红外灯下加热25天。使用扫描电子显微镜（SEM）检查了实验前后织物材料的微观结构特征以及土壤表面的结晶条件。结果表明，织物的亲水性和结构都影响除盐效率。尽管土工布去除的盐量（111.54 g m ^-2）小于纱布（293.89 g m ^-2）），考虑到长期蒸发，土工布在除盐方面显示出更大的潜力。为了进一步研究土工织物材料在除盐方面的性能，使用市售的，面密度为200、300、400和500 g m ^-2的土工织物重复该实验。500克间^-2土工可以删除368.15克米^-2盐，比盐与密度150，200，300的土工织物除去更多，和400g米^-2（111.54，61.57，102.05，和102.34克米^-2），这进一步证明了织物结构对除盐有很大的影响。这些结果表明，具有优化织物结构的土工织物覆盖物可能是一种有前途且对环境友好的农田盐渍化控制技术。
