摘要
为了解南团公路(沪南公路—南芦公路)绿化的土壤质量,分别采集了两侧绿化带、行道树、机非隔离带和中央分隔带等的57个采样单元,共计114个土样,主要进行了土壤养分状况的测试与统计分析.结果表明:土壤质地均属于壤质土,能满足植物正常生长;土壤有机质达较肥沃水平,土壤全氮和有效磷含量均达较丰富水平,土壤速效钾含量丰富;土壤综合质量主要以质量较好的二类土为主,无质量差的五类土和较差的四类土,有27.2%质量最好的一类土.
Abstract
In order to understand greening soil quality on the Nantuan Road(the Southern Shanghai Road-the Nanlu Road),a total of 114 soil samples in 57 sampling units were collected,such as green belts,border trees,mo-tor vehicle and non-motor vehicle isolation belts and central separation belts on both sides,and the soil nutrient sta-tus was mainly tested and statistically analyzed.The results are as follows:the soil texture belongs to loamy soil,which can meet the normal growth of plants;the organic matter in soil reaches a relatively fertile level,both the to-tal nitrogen and available phosphorus content in soil are at a relatively rich level,and the available potassium content in soil is abundant;the comprehensive soil quality is mainly dominated by Class Ⅱ soil with good quality,without poor-quality Class V soil and worse-quality Class Ⅳ soil and with 27.2%of best-quality Class I soil.
