摘要
采用不同配料配比堆制了7种堆肥。分析了它们的基本化学特性,铅、锌、镉3种重金属的总含量以及H2O、CaCl2和EDTA3种浸提剂所浸提的生物活性部分。结果表明:7种堆肥用于重金属污染土壤的改良是安全可靠的。
Seven composts were designed with different ingredients.Its chemical characteristics,total contents of three heavy metals-Pb、Zn、Cd and parts of bioactivity extracted with H_2O,CaCl_2 and EDTA were analysed.The results showed that seven composts were safe and reliable for remediation of heavy metals contaminated soils.
