摘要
[目的]研究田菁对大庆地区盐碱化土壤的改良效果。[方法]设置种植田菁和不种田菁(CK)2个处理,于2014—2016年进行田间试验,探讨其对大庆地区盐碱化土壤的改良效果。[结果]田菁适应大庆地区气候条件和盐碱化土壤环境,种植田菁能有效促进地表其他植被生长,降低土壤pH、可溶性盐含量、电导率及土壤速效磷含量和速效钾含量,提高土壤有机质含量和碱解氮含量。[结论]田菁对大庆地区盐碱化土壤和独特气候环境具有较强的适应性,可作为盐碱土改良的先锋树种在大庆地区引种。
[ Objective ] To study the improvement effect of sesbania on saline-alkali soil in Daqing area. [ Method] A three-year experiment was conducted in Daqing area to study the improvement effect of sesbania on saline-alkali soil by setting plant sesbania and no sesbania plant （CK） treatments in 2014 -2016. [ Result] Sesbania could adapt to the local climatic conditions and saline-alkali soil environment of Daqing area. Plant- ing sesbania promoted the other surface vegetation growth. Additionally, the contents of soil organic matter content and alkali hydrolyzable nitrogen content both increased after sesbania planting, soil pH, soluble salt content, EC value, soil available P content and available K content decreased. [Conclusion] Sesbani has strong adaptability to saline-alkali soil and the unique climate and environment in Daqing area,can be used as the pio- neer species in saline-alkali soil improvement in Daqing area.
