Abstract: In order to explore the effect of Fenlong remold in rebuilding and utilization of salin-alkali land, this paper invented Fenlong machine and technology, and carried out experiments from 2015-2016 in Xinjiang Autonomous Region and Shaanxi province, respectively. The results showed that in Xinjiang after Fenlong one season of cotton was grown on heavy saline-alkali soil, the total salt content in soil decreased 31.31%, while cotton yield increased 48.80%. The soil salinity level was fallen from “severe” to “moderate”. In Shaanxi, summer corn was grown after Felong on mild saline-alkali soil. The total salt content in soil decreased 42.37%, while corn yield increased 34.83%, and the soil salinity degree was changed from “mild desalination” to “normal farmland”. The paper provided the mechanism and reasons for pale salt in soil and yield increase by Fenlong.

Key words: Fenlong cultivation, saline-alkali land, pale salt, yield increase, prospect

摘要： 为探索粉垄改造利用盐碱地的效果，利用自主发明的粉垄耕作机械和粉垄技术，于2015-2016年分别在新疆和陕西等地进行了粉垄改造利用盐碱地试验，结果显示：在新疆的重度盐碱地经粉垄种植一季棉花后，土壤全盐量下降幅度31.31%，棉花产量增加48.80%，盐碱程度由重度降为中度；在陕西轻度盐碱地种植麦后夏玉米，土壤全盐量下降幅度42.73%，玉米产量增加34.83%，盐碱程度由轻度脱盐为正常耕地。最后分析了粉垄盐碱地淡盐增产的机理原因。
