摘  要：
选用5种不同类型的改良剂,对锌铬复合污染的土壤进行试验,分析了不同改良剂对土壤养分及重金属有效态含量的影响。结果表明:各改良剂的施入均改变了土壤pH,其中,过磷酸钙、麦秆及油菜秆降低了土壤pH值,石灰及兔粪提高了土壤pH值。5种改良剂均显著降低了土壤中的锌、铬有效态含量,其中,麦秆(高浓度)处理的土壤有效态锌含量最低,为20.00 mg/kg,较对照降低了53.25%;石灰(高浓度)处理的土壤有效态铬含量最低,为3.18 mg/kg,较对照降低了60.15%。除过磷酸钙和石灰降低了土壤速效钾含量之外,各改良剂处理均显著提高了土壤速效氮、磷、钾含量,其中,兔粪(高浓度)处理的土壤碱解氮含量最大,为124.56 mg/kg,比对照提高了41.51%;过磷酸钙(高浓度)处理的土壤速效磷含量最大,为42 mg/kg,较对照提高了133.33%;麦秆(高浓度)处理的土壤速效钾含量最大,为211.56 mg/kg,较对照提高了136.88%。

摘  要：
Five different types of modifiers were applied in compound pollution of zinc and chromium soil to analyze the effects of modifiers on zinc,chromium and nutrient availabilities in soil.Five modifiers changed the soil pH.Superphosphate,wheat straw and rape straw decreased soil pH,and lime and rabbit manure increased soil pH.Five modifiers significantly decreased the available zinc and chromium contents in soil.The lowest available zinc content(20.00 mg/kg) appeared in the wheat straw(high concentration) treatment,which decreased by 53.25% compared with CK,and the lowest available chromium content(3.18 mg/kg) appeared in the lime(high concentration) treatment by 60.15% compared with CK.All modifiers significantly increased the soil available phosphorus,potassium and alkaline hydrolyzed nitrogen contents,except that superphosphate and lime decreased available potassium content.The maximum alkaline hydrolyzed nitrogen(124.56 mg/kg) appeared in the rabbit manure(high concentration) treatment,which increased by 41.51% compared with the CK.The maximum available phosphorus(42 mg/kg) appeared in the superphosphate(high concentration) treatment,increased by 133.33% compared with the CK,and the maximum available potassium(211.56 mg/kg) appeared in the wheat straw(high concentration) treatment,increased by 136.88% compared with the CK.
