摘　　要：采用盆栽试验,研究了不同配施菌糠肥料对玉米生长状况及收获后土壤中不同形态Cu的质量分数及酶活性的影响。结果表明,与未配施菌糠处理相比,施用不同配方菌糠肥料后玉米株高、干物质量都有所增加,土壤中全Cu的质量分数降低了7.35%~11.56%,土壤中可交换态Cu质量分数平均增长了25.41%,碳结合态Cu质量分数平均升高了8.03%,有机结合态Cu质量分数有所升高,残渣态Cu质量分数有所降低,铁锰氧化态Cu质量分数变化不明显;与未配施菌糠处理相比,施用菌糠肥料后土壤中蔗糖酶活性变化显著,最大增幅96.25%,脲酶活性增幅最大为54.50%,过氧化氢酶活性平均增幅31.67%。说明不同配施菌糠肥料可有效改善Cu污染土壤环境,改善土壤微生物状况,促进玉米生长。Pot experiments were performed to study the effects of different application of fungus chaff fertilizer on maize growth,different forms of Cu content and enzyme activity in soil.Results showed that,compared with the control,after applying different formulas of fungus chaff fertilizer,the Cu content in soil reduced by 7.35%~11.56%,the content of exchangeable Cu in soil increased by 25.41%,the carbon combined Cu content increased by 8.03%,the organic？combined Cu content increased to some extent,the residue Cu content decreased a little,and the iron and manganese oxidation state Cu content had no significant change.Compared with the control,after applying the fungus chaff fertilizer,the enzyme activity in soil increased,invertase activity changed significantly,reaching the largest,which increased by96.25%,the urease activity in soil increased,the maximum reached 54.50%,and the average growth of hydrogen peroxide enzyme activity was 31.67%.Applying different formulas of fungus chaff fertilizer could effectively improve the soil enzyme activity in Cu contaminated soil and also improve soil microorganisms＇ condition.
