Rice cultivation is one of the effective ways for agricultural development and utilization of saline-alkali land in the semi-arid area of western northeast China. The fish farming in paddy field further enhances the comprehensive benefit of rice seed development and is a model of ecological fishery (agriculture) combined with planting and breeding. This paper takes the experimental area of fork dry town in Daan City of western Jilin as an example to introduce the technical measures for fish farming in the saline-alkali soil. 1 pressure alkali salt test plots for the heavy saline soil, 0 ~ 3 0cm soil layer
