【摘要】:為了研究齊齊哈爾市主城區(qū)住宅小區(qū)綠地土壤理化性質(zhì),以齊齊哈爾市主城區(qū)12個住宅小區(qū)綠地土壤為研究對象,采集齊齊哈爾市主城區(qū)12個住宅小區(qū)綠地0~≤10 cm和10~≤20 cm土壤,測定了土壤容重、孔隙度、自然持水量、p H值、有機(jī)質(zhì)、全氮、全磷、全鉀指標(biāo)數(shù)據(jù)。結(jié)果表明:齊齊哈爾市主城區(qū)住宅小區(qū)綠地表層土壤容重、土壤孔隙度均為適宜,土壤自然持水量偏低;土壤p H值較自然土壤明顯增高,呈堿性;在0~≤10 cm和10~≤20 cm土壤中,有機(jī)質(zhì)含量處于低等偏下水平;全氮含量處于中等水平;全磷含量處于低等水平;全鉀含量處于低等水平。說明齊齊哈爾市主城區(qū)住宅小區(qū)綠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,
