摘要
通过大田试验,探讨了不同形态纳米硒对绿茶富硒效果,以及镉铅累积效应的影响.结果表明,采用叶施方式,纳米硒尤其是化学纳米硒能够以较低的投入实现富硒茶生产,但对镉铅的累积效应同步增强,其内在机理还需进一步研究.在各种纳米硒试验中,离心处理后的生物纳米硒(BioSeNPs)能够实现绿茶硒富集同时抑制茶叶对镉铅等重金属的吸收,具有产业化发展应用的潜力.
Abstract
A field experiment of using foliage Se was designed to research the effect of Se,Cd Pb-concentration in green tea product using dif-ferent nano-Se.The results showed that using nano-Se especially chemical nano-Se had an obvious effect than others to realize the tea produc-tion with Se-concentration as well as Cd,Pb accumulations.And the inner mechanism need to further research.In various nano-Se experiments,BioSeNPs with centrifugal treatment could realize Se-concentration as well as restrain Cd and Pb absorption in the process of green tea produc-tion.
