【摘要】:为了研究齐齐哈尔市主城区住宅小区绿地土壤理化性质,以齐齐哈尔市主城区12个住宅小区绿地土壤为研究对象,采集齐齐哈尔市主城区12个住宅小区绿地0~≤10 cm和10~≤20 cm土壤,测定了土壤容重、孔隙度、自然持水量、p H值、有机质、全氮、全磷、全钾指标数据。结果表明:齐齐哈尔市主城区住宅小区绿地表层土壤容重、土壤孔隙度均为适宜,土壤自然持水量偏低;土壤p H值较自然土壤明显增高,呈碱性;在0~≤10 cm和10~≤20 cm土壤中,有机质含量处于低等偏下水平;全氮含量处于中等水平;全磷含量处于低等水平;全钾含量处于低等水平。说明齐齐哈尔市主城区住宅小区绿地土壤肥力水平偏低。
[Abstract]:In order to study the soil physical and chemical properties of green space in the main residential district of Qiqihar City, the green land soil of 12 residential districts in Qiqihar City was taken as the research object. The soil density, porosity, natural water holding capacity, organic matter, total nitrogen, total phosphorus and total potassium were measured. The results showed that the surface soil bulk density, soil porosity and natural water holding capacity of green land in main residential district of Qiqihar City were all suitable, the soil pH value was significantly higher than that of natural soil, and the soil pH value was alkaline. In 0 ~ 鈮,
