| 摘 要： | 对东部发达地区典型乡镇的绿地土壤进行了调查分析,结果表明:该区绿地土壤pH值呈中性偏碱,磷素、钾素质量分数中等,氮素、有机质质量分数较小;绿地土壤肥力综合评价分值IF,I整体偏低,肥力状况较差;固有的绿化模式存在一定缺陷,建议"自下而上"地以绿地土壤性质分析为关键开展绿化工作。

| Abstract: | The nutrients of greenbelt soil in Xinzhuang Village in South Jiangsu were analysed in terms of pH,organic matter,available phosphorus,total phosphorus,total potassium,available potassium and available nitrogen.Results show that the greenbelt soil is neutral or alkaline,the contents of available phosphorus,total phosphorus,total potassium and available potassium are at medium level,and the contents of available nitrogen and organic matter are at low level.The integrated fertility index (IFI) value of the so... |
