本文研究了重盐渍土（盐池）直接冲洗种稻淹水条件下的盐分变化动态。试验表明，在淹水条件下始终保持田面淡水层，即使土壤含盐量大于4g／kg也能保障水稻正常生长。
In this paper, the salinity changes under heavy salt saline soil (salt pool) irrigation were studied. Experiments show that in submerged conditions always maintain the surface freshwater layer, even if the soil salinity greater than 4g / kg can protect the normal growth of rice.
