In this study, the author focused on the fact that salt accumulation occurred in a very thin soil surface layer and developed a new technology,"Surface Suction Leaching Method(SSLM)", as a water-saving desalinization method for salt-damaged field. In the method, a little water was supplied into soil surface layer to dissolve accumulated salts and it was removed by the instrument of SSLM with dissolved salts. As results of performance experiments, it could remove 80% of salt in sandy soil and 89% in sandy loam soil, respectively. Both of them, more than 90% of supplied water was collected. Although the rate of removing salts in naturally-occurring salt-damaged fields was only 60%, the basic technology for water-saving desalinization method could be established

本研究针对盐碱地土壤表层积盐的特点，提出了一种新的盐碱地节水除盐技术--“表面吸滤法"。该方法通过向土壤表层注入少量水，溶解土壤表层积累的盐分，然后用溶解盐SSLM仪将土壤表层积累的盐分去除。性能试验结果表明，该菌对桑迪土壤和桑迪的脱盐率分别为80%和89%。在这两种情况下，90%以上的供水都是收集的。虽然天然盐害田的脱盐率仅为60%，但可为节水型脱盐方法奠定基础
