采用翻地、施肥和芦苇碎屑培肥等土壤改良方法,利用盐地碱蓬在黄河三角洲重度退化区进行生态修复实验研究。结果表明:重度退化湿地土壤改良后,盐地碱蓬能够成功生长,3种改良方法均可有效的降低重度退化盐碱地的土壤含盐量,改良后的土壤Na离子含量均显著低于对照组,土壤脲酶和磷酸酶活性与对照相比有了显著的提高,表明改良后土壤肥力得到了改善。3种改良方法比较,培肥处理组土壤Na离子含量显著低于其他两种方法; 盐地碱蓬生物量达到最高值,说明增加有机物的培肥方法可有效的改良重度退化盐碱湿地土壤,达到较为理想的生态修复预期效果。  

The Yellow River Delta is one of the most active regions of land-ocean interaction among the large river deltas in the world.However,the wetlands in Yellow River Delta have been suffering from soil salinity and increasing degradation,because of the coastal erosion and drying up of the Yellow River.Therefore,it′s essential to develop efficient eco-remediation methods on heavily degraded coastal saline-alkaline wetlands to protect wetlands resources.To study the ecological effects of Suaeda salsa on repairing...
