哈尔滨城市绿地土壤肥力调查与评价

Survey and Evaluation of Soil Fertility in Harbin Urban Green Space

对采集于哈尔滨城市广场绿地、高校附属绿地和苗圃生产绿地0～20cm土壤的pH值和速效氮、速效磷、速效钾等各项土壤肥力指标进行了测试分析。结果表明:测试绿地的土壤pH呈碱性,土壤速效氮、速效磷、速效钾含量明显高于苗圃生产绿地,肥力处于中等或以上水平。

Collectting soil 0~20 cm from Harbin city square green space,college attached green space and nursery production green space soil pH value and available nitrogen,available phosphorus and available potassium of the soil fertility index were tested.The results showed that the soil pH of tested green space was alkaline,and the content of the soil available nitrogen,available phosphorus,and available potassium was obviously higher than that of the nursery production green space,in a medium or above level.
