摘要
对宿迁市宿城区部分园林绿地土壤进行了理化分析,结果表明:大部分园林绿地土壤为碱性,有机质含量较低,全量氮、磷、钾和有效氮、磷、钾含量均低于农田土壤相应养分含量。建议对城市园林土壤进行长期的跟踪研究,以掌握其动态变化;制定城市园林土壤的使用标准,以规范城市园林土壤的使用。
The garden soil nutrition were analysised,the results show that the most of soil is alkaline,the organic matter content is very low,total nitrogen 、phosphorus and potassium are all lower than that of agricultrural soil.The suggestion is to study on urban soil for long to master dynamic changes.And making relative standard to standardize the use of urban soil.
