| Abstract: | 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.Planting 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 pioneer species in saline-alkali soil improvement in Daqing area. |
