摘要
In order to explore the effect of Fenlong cultivation in rebuilding and uti- lization of saline-alkali land, the Fenlong tillage machine and Fenlong technology were invented and put into tests in the saline-alkali land from 2015-2016 in Xinjiang Autonomous Region and Shaanxi province, respectively. The results showed that in Xinjiang, the total salt content in the heavy saline-alkali soil decreased by 31.31% after one season of cotton planting using Fenlong, while cotton yield increased by 48.80%, and the soil salinity level was fallen from ＂severe＂ to ＂moderate＂ level. In Shaanxi, the total salt content in decreased by 42.73% after planting summer corn summer corn the mild saline-alkali land using Fenlong cultivation, while the corn yield increased by 34.83%, and the soil salinity degree was changed from ＂mild de- salination＂ to ＂normal farmland＂. At last, the paper provided the mechanism and reasons for desalination in soil and yield increase by Fenlong cultivation.
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。
