摘  要：
通过田间定位试验,采用石灰、钙镁磷肥、泥炭、猪粪、石灰+泥炭、石灰+猪粪、钙镁磷肥+泥炭、钙镁磷肥+猪粪等处理对污染田进行改良。试验表明,大部分处理能提高土壤的pH值、有机质含量、碱解氮及速效磷含量;各处理pH值大小顺序为,钙镁磷肥+泥炭、钙镁磷肥、钙镁磷肥+猪粪>石灰+猪粪、石灰+泥炭、石灰>泥炭、猪粪。经统计分析,土壤pH值与土壤有效镉、有效铅、有效铜含量之间呈显著负相关。说明通过提高土壤pH值,降低土壤重金属活性是有机—中性化改良技术的主要机理。

摘  要：
The field plot experiments were conducted on a heavy metal polluted soil. Eight treatments including lime (L). calcium magnesium phosphate (G), peat (P). hog manure (M), lime and peat (LP), lime and hog manure (LM). calcium magnesium phosphate and peat (GP), calcium magnesium phosphate and hog manure (GM) were used. The result showed that most treatments could increase the soil pH, organic matter, alkaline hydrolysable nitrogen, readily available phosphorus; the decrease order of pH value was GP, G, GM>LM, LP, L>P, M. Statistical analysis indicated that the content of available cadmium and available lead in soil was significantly and negatively correlated with soil pH. It was suggested that through increasing soil pH by liming and then decreasing the available heavy metals in soil was the main mechanism for organo-neutralization.
