绿化种植土壤肥力的分析与研讨

Analysis and Discussion on Soil Fertility of Green Planting

通过对深圳市某在建设中的地块绿地土壤进行采样分析,研究了土壤pH、EC值、阳离子交换量、有机质、全磷、有效磷、速效钾、碱解氮等肥力特征。结果表明,绿地土壤的表层土壤中:pH值的范围为6.89~9.25之间,平均值8.11,碱性土壤占比90.5%,EC值的范围为0.07~1.72 mS/cm之间,平均值0.047 mS/cm,阳离子交换量、有机质、碱解氮的含量处于较低水平,全磷、有效磷、速效钾的含量处于中等偏上水平。

Through the sampling and analysis of green soil of a plot under construction in Shenzhen,soil pH,EC value,cationic exchange amount,organic matter,whole phosphorus,effective phosphorus,quick-acting potassium,alkaline nitrogen and other fertility characteristics were studied.The results showed that in the surface soil of green soil:the pH value range was between 6.89~9.25,the average value was 8.11,the alkaline soil accounts for 90.5%,the range of EC value was between 0.07~1.72 mS/cm,and the average value was 0.047 mS/cm.The content of cation exchange,organic matter and alkaline nitrogen is at a low level,and the content of total phosphorus,effective phosphorus and quick-acting potassium is at a medium and upper level.
