江苏沿海盐场依靠海水蒸发结晶制盐，占地面积大、成本高、质量差，加之原盐供过于求，经济效益较差，已有多家盐场正在进行盐改农的尝试。江苏省农科院土肥所经几年的试验研究表明，当年洗盐当年种稻是可能的，但要获得较稳定的产量仍有许多技术问题必须加以研究和改进。为达 Jiangsu coastal salt water relies on salt water evaporation crystallization of salt, covers an area of ​​large, high cost, poor quality, coupled with the excess supply of raw salt, poor economic efficiency, there are a number of salinities are salt farming attempt. Several years of experimental study on soil fertilizers by Jiangsu Academy of Agricultural Sciences have shown that it is possible to grow rice in that year, but many technical problems still need to be studied and improved in order to obtain more stable yields.
