盘锦“红海滩”退化初探

Discussion on Degeneration of Red Beach of PanJin

本文采用海水监测、翅碱蓬野外调查及盆栽试验和室内分析方法,研究了盘锦"红海滩"翅碱蓬群落的退化死亡原因,特别是翅碱蓬退化死亡与土壤盐分的关系。结果表明,翅碱蓬适宜的土壤盐分含量在10g/kg至16g/kg之间,初步认为由于滩涂土壤盐分升高产生的盐害是引起盘锦"红海滩"翅碱蓬群落退化死亡的主要原因。

We researched on degenerated and died reason of Suaeda salsa in red beach of PanJin with seawater monitoring,field survey,pot experiment and laboratory analysis,especially on relationship of degenerating and dying of Suaeda salsa and salinity of soil.The result showed that soil salt content suitable for Suaeda salsa was between 10g/kg and 16g/kg,the main reason of Suaeda salsa degenerating and dying was salt injury causing by increased soil salinity
