摘 要:
为解决填海造地的土壤改良与绿化难题,对曹妃甸新区滩涂土壤和填海造地土壤的基本性状做了调查研究,并对采用"节水型盐碱滩地物理-化学-生态综合改良及植被构建技术"土壤改良及绿化效果进行了分析。结果表明,实行综合改良后2个月,土壤含盐量由13.07g/kg降至1.55~1.67g/kg,地下水矿化度由20g/L降至10g/L;土壤有机质、无机养分大幅提高,土壤容重降低;绿化成活率达到98%。

摘 要:
This study aims to solve the problem of soil improvement greening in sea reclaimed land. We investigated the soil characters of mudflat and sea reclaimed land in Caofeidian new district, then we used water-saving physical-chemical-ecological comprehensive improvement technique and vegetation rehabilitation technique in salina to analyze the effects of soil improvement greening. The results indicated that soil salt content decreased from 13.07 g/kg to 1.55~1.67 g/kg after two months of soil improvement greening, and mineralization degree of groundwater decreased from 20 g/L to 10 g/L. Soil organic matter and inorganic nutrients significantly increased, while soil bulk density decreased. Greening survival rate reached to 98%.
