摘　　要：通过对茶树叶面喷施不同浓度的硒肥试验,探讨外源硒对茶叶产量以及硒、镉含量的影响。结果表明,在酸性富硒土壤中,叶面喷施外源硒,对茶叶增产效果显著,同时促进茶叶有机硒的转化积累,有效抑制镉的吸收,为外源硒在茶叶中的富集和推动富硒茶叶生产提供参考。Through the experiment of spraying different concentrations of selenium fertilizer on tea leaves,the effects of exogenous selenium on tea yield and the contents of selenium and cadmium were discussed.The results showed that in acidic selenium rich soil,foliar spraying of exogenous selenium had significant effect on increasing the yield of tea,promoted the transformation and accumulation of organic selenium in tea and effectively inhibited the absorption of cadmium.It provides a reference for the enrichment of exogenous selenium in tea and the production of selenium rich tea.
