中文摘要	以松嫩平原西部内陆盐碱湿地的重度苏打盐化草甸土与盐土、碱土镶嵌形成的复区为对象,进行了种稻脱盐过程试验.在不采取化学、物理等其他措施的前提下,单纯采用种稻水洗方法,经过5年连续试验,土壤表层平均盐分质量分数由4.5%降至0.15%,水稻产量由第1年的近于零,上升到第4年的4250 kg/hm2,表明运用简单的种稻脱盐方法改良强度苏打盐化草甸土与盐土、碱土复区具有可行性.这一结果对合理利用劣质土壤资源和重建西部严重荒漠化生态景观具有指导意义
英文摘要	This paper took the intensely salinized meadow soil of soda and solonetz-solochak complex in the inland environment of west Songnen Plain for researched object, demonstrated the desalinization process with cultivating paddy. Under the precondition of oo chemical and biological steps but water bathing through cultivating rice, after four years of successive test, the average salt con-tent of the top soil in the depth of 30 cm decreased from 0.45% to 0.15%. The output of rice increased from approximate zero in tlae first year to 4 250 kg/hm~2 in the fourth year, which indicates it is feasible to improve the intensely salinized meadow soil by the sim-ple desalinization method of cultivating paddy. These results are significant for the using of disadvantage land resources and for tlae improving the seriously deserted ecological landscape in the western China.
