摘  要:
为了研究齐齐哈尔城市绿地土壤理化性质,以齐齐哈尔市主城区公园绿地、高校绿地、居住区绿地土壤共计12样地为研究对象,采集齐齐哈尔市主城区绿地土壤12个样地0~20 cm土壤,测定了土壤容重、pH值、有机质、全磷、全氮、全钾指标数据。结果表明:齐齐哈尔城市绿地土壤容重偏紧或过紧实,土壤呈碱性(pH平均值大于7.9),土壤有机质和全磷含量偏低,全氮含量适中,而全钾的含量相对较高。齐齐哈尔城市绿地土壤肥力由低到高为居住区绿地<高校绿地<公园绿地。因此,在不同绿地类型进行城市绿化时,应注意城市绿地土壤的特点。

摘  要:
In order to study soil physico-chemical properties of Qiqihar urban greenbelt, with central district parkland, campus and residential green spaces adding up to 12 sample plots as the research objects, 0~20 cm sample soil was collected and soil bulk density, pH, organic matter, total phosphorus, nitrogen and potassium were tested. The result showed that soil bulk density was too dense, soil appeared to be alkaline(average pH>7.9), organic matter and total phosphorus were too low, total nitrogen was medium and total potassium was relatively high. The soil fertility of Qiqihar urban greenbelt was proved to be residential
