| Research Abstract |
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
