| 摘 要： | 对淮海经济区主要城市绿地土壤的理化性质进行了研究。结果表明:该地区绿地土壤以壤质砂土、砂质壤土、壤质粘土为主,土壤硬度为10.61~21.34 kg/cm2,基本能满足植物生长发育的需要;有机质含量为0.83%~1.48%,全氮含量0.051%~0.094%,全磷含量0.038%~0.069%,全钾含量1.685%~2.038%均低于当地农业土壤,土壤pH值7.60~8.63偏碱性。其有效养分含量不均,土壤养分间相关性差。

| Abstract: | The physical and chemical characters of soil in urban green space of main cities in Huaihai economic zone were studied.The results showed that the main soil types were loamy sand,sandy loam soil and loam clay,and the soil hardness was 10.61 ~ 21.34 kg/cm2,the requirements of plant growth could be basically satisfied.The contents of organic matter,whole N,whole P and whole K were 0.83 % ~ 1.48 %,0.051 % ~ 0.094 %,0.038 % ~ 0.069 % and 1.685 % ~ 2.038 % respectively.The soil pH was 7.60 ~ 8.63.The content of available nutrients was not even,and correlation between different nutrients was low. |
