哈尔滨城市绿地土壤肥力调查及评价

摘要

通过实测并分析哈尔滨主城区的道路绿地、高校附属绿地、苗圃生产绿地以及公园绿地的31个样点土壤p H值、有机质、速效氮、速效磷和速效钾肥力指标可知:哈尔滨市道路绿地、高校绿地土壤大多呈碱性, 苗圃绿地、公园绿地土壤属于中性或偏酸性.高校附属绿地和苗圃生产绿地的有机质、速效氮、速效磷、速效钾的平均含量较丰富, 而在街道绿地中含量相对较低.%In order to determine the soil fertility status of park, campus, nursery and road green space in the central district of Harbin, the pH value, organic matter, available nitrogen, phosphorus and potassium were measured at 31 sampling points in Harbin urban greenbelt. The results showed that the soil of road and campus green space was mostly alkaline, and the soil of nursery and park green space belonged to neutral or acidic soil. The average contents of organic matter, available nitrogen, phosphorus and potassium in the green space of campus and nursery were relatively plentiful, whlie the contents in the street green space were relatively poor.
