摘要:

为探索茶园土壤及茶叶重金属污染防治的方法,本研究以余杭径山镇茶园为研究对象,通过野外采集样品和测定分析,研究了酶制剂施用对茶园土壤和茶叶重金属含量的影响。结果表明:与CK相比,施用酶制剂极显著降低了茶园土壤中的pH及Cd、Cr、Hg和As 4种重金属的含量,但增加了土壤中Pb的含量;显著减少了茶叶中Pb的含量,极显著减少了茶叶中Cr和As 2种重金属的含量,降低了茶多酚含量。茶叶中Cd和Hg 2种重金属未检出。该酶制剂有效降低了茶叶中Pb、Cd和Hg等重金属含量,在保证茶叶质量安全方面具有较好的应用前景。

Abstract:

To explore the prevention and control methods of heavy metal pollution in tea garden soil and tea leaves, the effects of enzymes application on heavy metals content in tea garden soil and tea leaves were studied by field sample collection and determination analysis in Jingshan Town of Yuhang. The results showed that compared with the CK, enzymes application treatment significantly reduced the pH and the content of Cd, Cr, Hg and As in tea garden soil, but increased the content of Pb in tea garden soil. The content of Pb and tea polyphenols in tea leaves was reduced, and the content of Cr and As was significantly reduced. The content of Cd and Hg was not detected in tea leaves. The enzymes application can effectively reduce the content of heavy metals such as Pb, Cd and Hg, and it has a good application prospect in ensuring the quality and safety of tea.

Key words: enzymes, tea garden soil, tea leaves, heavy metal
