摘要

采用理化分析、土壤微生物活性表征和直接固相生物测定等方法研究了城市固体废物堆肥(MSWC)连续添加对土壤的长期影响。连续四年,每年用不同数量的突尼斯MSWC和传统农用肥料对未植被的土壤地块进行改良。尽管有机改良剂对土壤理化性质有影响,但改良剂类型和添加量对土壤生态毒性、微生物生长和酶活性的长期影响均不显著。

Assessment of the Effect of Repetitive Municipal Solid Waste Compost Application on Soil Using Physico-chemical Analyses, Solid-phase Bioassays and Microbial Activity Characterization
The long term impact of successive municipal solid waste compost(MSWC)amendments on soil was investigated using physico-chemical analyses, soil microbial activity characterization and direct solid-phase bioassays. Unvegetated soil plots had been yearly amended with different amounts of Tunisian MSWC and conventional farm manure(FM) for four consecutive years. Despite the changes in physico-chemical properties of organically amended soils, neither the amendment type nor the incorporated amount had significant effects on soil ecotoxicity, microbial growth and enzymatic activities at long-term.
