摘要
为了研究深圳公园绿地土壤理化性质,在大量调查的基础上,以深圳市5个主要公园绿地土壤为研究对象,测定了土壤容重、土壤质地、pH、有机质、全氮、全磷、有效磷、全钾、速效钾、全盐量和总硫等土壤理化性质。结果表明,深圳市土壤偏紧,土壤质地为粉砂质壤土,土壤pH为6.2~7.0,有机质含量处于中等偏下水平,磷含量处于很低的水平,而钾含量处于极低水平,远低于园林绿地种植的最低标准。
In order to study the physical and chemical properties of soil in Shenzhen Park Greenland, on the basis of a large number of investigations, five major parks in Shenzhen were studied, soil bulk density, soil texture, pH, organic matter, total nitrogen, total phosphorus, available phosphorus, total potassium, available potassium, total salt and total sulfur and other soil physical and chemical properties were determined. The results showed that the soil in Shenzhen was relatively tight, the soil texture was silty loam, the pH of the soil was 6.2 - 7.0, the content of organic matter was in the lower middle level, the content of phosphorus was in the low level, and the content of potassium was in the very low level, far lower than the minimum standard of landscape planting.
