The controlling of secondary soil salinization may take into account four main complex factors: leaching, groundwater table, time and modifier in the west of Songnen Plain. The change of salinity characteristic is analysed for soil profile during comprehensive harnessing and its effects on the characteristic of circumjacent soil are also studied. And through experiment, the paper studies the effects of different water-applying regimes on the changes of soil salinity in plowed layer. Based on a series of comprehensive experiments of applying soil amendment, the comprehensive technology system for preventation and treatment of soil secondary salinization in this region is established.
