为了研究齐齐哈尔城市绿地土壤肥力质量,以齐齐哈尔市主城区公园绿地、居住区绿地、生产绿地、道路绿地、单位附属绿地、沿岸绿地等6种绿地土壤作为研究对象,采集了齐齐哈尔市主城区绿地>0~≤20 cm和>20~≤40 cm土壤,测定土壤容重、p H值、有机质、速效氮、全磷、全钾等指标。结果表明:齐齐哈尔城市绿地土壤容重值偏大,绿地土壤总体呈碱性,绿地土壤有机质、速效氮、全钾含量普遍处于低等水平,全磷含量处于中等水平。>0~≤20 cm土层绿地土壤综合肥力指数的大小依次为生产绿地、道路绿地、单位附属绿地、沿岸绿地、公园绿地、居住区绿地;道路绿地、单位附属绿地、沿岸绿地、居住区绿地土壤肥沃程度均处于中等偏低水平,而公园绿地和生产绿地土壤肥沃程度处于良好水平。>20~≤40 cm土层绿地土壤综合肥力指数的大小依次为居住区绿地、道路绿地、公园绿地、单位附属绿地、生产绿地、沿岸绿地;土壤各种绿地类型肥沃程度均处于中等水平。
In order to study the quality of urban greenland soil fertility in Qiqihar City, six kinds of greenbelt soil such as parkland, residential greenbelt, greenbelt, road greenbelt, affiliated greenbelt and coastal greenbelt in the main urban area of Qiqihar City were taken as research objects, 0 ~ ≤20 cm and> 20 ~ ≤40 cm soils, soil bulk density, p H value, organic matter, available nitrogen, total phosphorus and total potassium were measured. The results showed that the soil bulk density value of urban greenbelt in Qiqihar was large and the green soil was alkaline. The contents of soil organic matter, available nitrogen and total potassium in the green land were generally low and the total phosphorus content was moderate. > 0 ~ ≤ 20 cm. The order of soil fertility index in order of production green land, road green space, affiliated greenbelt, coastal greenbelt, park greenbelt, residential greenbelt; road greenbelt, affiliated greenbelt, coastal greenbelt, residential greenbelt Soil fertility is at a moderately low level, while the fertility of parkland and greenbelt is at a good level. > 20 ~ ≤40 cm soil fertility index of greenbelt in order of residential green space, road green space, park green space, afforestation green space, production green space, coastal green space; soil fertility of various types of green spaces are at a moderate level.
