摘要
城市绿地土壤是一类特殊的土壤,人为影响较大,也是植物生长的基础,为提高重庆市垫江县土壤利用和管理水平,调查了重庆市垫江县南阳公园绿地土壤,系统分析、评估公园绿地土壤质量状况。结果表明:调查区域大部分土壤为强碱性土壤,有机质含量总体较低,氮、磷含量整体偏低,钾含量尚可。绿地土壤质量整体偏低,容易对植物生长造成阻碍。后期施用肥料比较容易提供养分含量,建议合理施用氮磷钾肥,偏施氮肥和磷肥,同时结合施用有机肥料。
The urban green space soil is a special kind of soil,which had great influence on human,and it is the basis of plant growth.In order to improve the soil utilization and management level of Dianjiang county of Chongqing city,through the investigation of urban green space soil on Nanyang Park in Dianjiang county,the soil quality of park green space was analyzed and evaludated systematically.The research showed that the most of the soil in survey area was strongly alkaline soil,and the organic matter content was generally low,the content of nitrogen and phosphorus potassium content was generally low.The whole quality of green space soil was low,which was easy to hinder the growth of plants.Late application of fertilizers was easier to provide nutrient content,it was recommended that reasonable application of N,P,K,prefer N and P combineed with organic fertilizer.
