摘要：

为了探索木段法和菌袋法栽培对黑木耳重金属含量的影响，寻找科学栽培方法。通过采用单因素方差分析和多重比较的方法，对塔河县、绿春县和伊春市野生、木段法栽培和菌袋法栽培黑木耳样品的铅、镉、汞和砷含量进行差异显著性分析。结果表明：45个黑木耳样品铅含量0.15~0.57 mg/kg；镉含量0.019~0.116 mg/kg；汞含量0~0.56 mg/kg；砷含量0.22~2.1 mg/kg。野生黑木耳之间镉、汞和砷含量差异极显著。不同栽培方法之间铅、镉差异极显著，汞差异显著，砷差异不显著。由此得出，木段法栽培黑木耳重金属含量低于野生黑木耳及菌袋法栽培黑木耳；木段法栽培黑木耳重金属含量更容易控制，是较好的栽培方法。

Abstract:

In order to finding a scientific cultivation method to get lower heavy metal contents A. auricula, the methods of one-way ANOVA and multiple comparisons were used to analysis the difference significant of the contents of Pb, Cd, Hg and As in 45 fruit bodies of the wild or cultivated A. auricula. The results showed that, the average contents of 45 tested samples were: Pb was 0.15-0.57 mg/kg, Cd was 0.019-0.116 mg/kg, Hg was 0-0.56 mg/kg and As was 0.22-2.1 mg/kg. Except lead, wild jelly ears were significant difference in heavy metal contents. The heavy metal contents of ‘‘tree trunks’’ jelly ears were lower than those cultivated by ‘‘polypropylene bags’’; the method ‘‘tree trunks’’ was better than ‘‘polypropylene bags’’ in this research.
