| 摘 要： | [目的]探讨城市污泥堆肥施加于菠菜地的可行性及其施加控制量。[方法]以北京市庞各庄污泥堆肥厂的污泥堆肥作为蔬菜地施用的有机肥源,采用自制土柱试验装置,研究不同用量污泥堆肥施用后菠菜的生长情况及对土壤的影响。试验设4个处理,污泥堆肥施用量分别为0（ck）、2、4、和6 kg/m2。[结果]壤土和沙土上不同用量污泥堆肥施用后,菠菜的株高、冠幅和叶面积都有一定的增加,对菠菜生长有促进作用,以4 kg/m2处理的效果最好。污泥堆肥施用后对菠菜重金属含量有显著影响,明显提高了菠菜地土壤中养分及有机质含量,污泥堆肥用量与污泥中重金属含量之间呈显著相关关系。[结论]城市污泥堆肥可以施加于蔬菜地,施加量以4 kg/m2为宜。
