N、P调控外源Se、Zn对茶叶元素含量及抗氧化能力的影响

Effect of N and P regulating exogenetic Se and Zn on elements content and antioxidant ability in tea

  • 摘要: 选取以江西为代表的丘陵红壤区生长的茶树作为研究对象,通过在土壤中添加外源Se、Zn并进行N、P调控,研究一芽二叶和老叶中Se、Zn、Al、Mn四种元素含量、茶多酚含量以及茶叶抗氧化能力的变化。以期探寻在降低茶叶中Al、Mn含量的同时提高茶叶自然品质的新种植方法。实验结果表明,通过N、P调控外源Se、Zn进行种植后,一芽二叶和老叶中Se、Zn含量升高,最多分别提高255.65%和100.45%;Al、Mn含量降低,最多分别降低39.27%和35.85%;茶多酚含量提高,并且抗氧化能力增强。 

     

    Abstract: Tea, planted in Jiangxi province which was representation of hilly red soil region, was selected as research objects. By adding exogenetic Se and Zn which were regulated by N and P in soil, variation of Se, Zn, Al and Mn content, total phenolic content, as well as antioxidant ability in two leaves and a bud and old leaves were investigated. A new plant method which could decrease the content of Al and Mn and improve the natural quality of tea was expected to be explored. The results showed that the content of Se and Zn increased, which the highest growth rate respectively were 255.65% and 100.45%, while the content of Al and Mn decreased which the highest reduction rate were 39.27% and 35.85% through soil regulation. Moreover, the total phenolic and antioxidant ability of the tea increased.
