摘要： 土壤的质量是决定城市园林绿化成功与否的关键因素。为了解调理剂对土壤质量的影响，以典型搬迁地土壤为研究对象，研究了不同调理剂、不同施用方法及不同时间土壤理化性质变化特征。结果表明：施用不同调理剂后，在一段时间内各调理剂均可有效降低搬迁地土壤pH、增加土壤EC值，而对土壤有机质、全氮均有一定程度降低趋势，其中Fe-S处理降低最明显。各处理对土壤总孔隙度、非毛管孔隙度和毛管孔隙度有一定降低，增加土壤容重，降低土壤入渗率、最大持水量及毛管持水量，其中M-S处理效果相对其他处理较差；各处理对种子发芽指数有所降低，其中Fe-I处理相对其他处理较差。尽管调理剂对搬迁地土壤化学性质具有一定的改善效果，但对土壤物理性质改善不明显，因此，建议调理剂与有机改良材料混合使用，以达到土壤理化性质改良效果，满足搬迁地绿化需求。

Abstract:

As the basis for plant growth, soil quality directly determines the success or failure of landscaping in urban areas. To understand the impact of conditioners on soil quality, we selected typical relocation site soil as the research object, and studied the impact on physical and chemical properties of the soil under different conditioners, different application methods and different time. The results showed that after applying different conditioners, each conditioner could effectively reduce the pH and increase the EC value of the relocated soil within a period of time, while the organic matter and total nitrogen of the soil had a tendency of decreasing to a certain extent, among which the decrease of Fe-S treatment was the most significant, while other treatments were not obvious; the impact of each conditioner on soil physical properties did not demonstrate clear improvement, which was mainly observed in the reduction of total soil porosity, non-capillary porosity and capillary porosity, increase of soil bulk density, decrease of soil infiltration rate, maximum water holding capacity and capillary water holding capacity. And among these treatments, M-S showed relatively poorer results; each treatment reduced the seed germination index, but the difference was not obvious, and the Fe-I treatment had poorer results than other treatments. The application of conditioner can improve the chemical properties of the soil in urban relocation site to a certain extent, but it is not obvious to improve the physical properties of the soil. Therefore, to achieve the desired effect of improving both the physical and chemical properties of the soil, it is suggested that the conditioner should be mixed with organic amendment materials.
