吴长锋：福建泰宁朱口茶叶硒含量特征与影响因素分析39第1期福建地质GeologyFujian第1期福建泰宁朱口茶叶硒含量特征与影响因素分析吴长锋（福建省闽西地质大队，厦门，361000）摘要以泰宁朱口茶叶及其根系土壤为研究对象，对其硒含量特征进行分析，并对影响茶叶硒含量的因素进行探讨。研究发现，研究区茶叶硒含量为0.03～0.36mg/kg，为富硒茶叶；茶叶根系土壤硒含量为0.07～0.85mg/kg。春茶中硒含量累积吸收较秋茶更强，变质岩系下茶叶硒含量高于碎屑岩系，根系土壤硒含量在0.40～0.50mg/kg时，为研究区茶叶硒最佳富集的土壤范围；根系土壤pH值与茶叶硒富集系数呈显著正相关（r=0.87，p＜0.05），根系土壤有机质与茶叶硒含量呈显著正相关（r=0.91，p＜0.05），根系土壤中Cr、As、Hg和Ni等重金属元素与茶叶硒富集系数呈显著负相关（p＜0.01）。关键词茶叶硒含量根系土壤影响因素福建泰宁中图分类号：S571.1文献标识码：A文章编号：1001-3970(2023)01-0039-09AnalysisofTeaSeleniumContentCharacteristicandItsInfluencingFactorsinZhukouarea,TainingCounty,FujianProvinceWuChangfeng(WesternFujianGeologicPartyofFujianProvince，Xiamen，361000)AbstractAbstractTakingteaanditsrootsoilinZhukouofTainingcountyastheresearchobject,weanalyzethecharacteristicsofSecontent,deeplydiscussthefactorswhichaffecttheSecontentoftea.Throughresearch,wefoundtheSecontentofteaintheresearcharearanged0.03~0.36mg/kg.andselenium-richteaisfoundinthisarea.TheSecontentofrootsoilranged0.07~0.85mg/kg.ThecumulativeabsorptionabilityofSeinspringteaisstrongerthanthatinautumntea.TheSecontentofteainmetamorphicrockishigherthanthatinsedimentaryrock.Secontentofrootsoilintherangeof0.40~0.50mg/kgisthebestsoilrangeforseleniumenrichmentofteaintheresearcharea.ThereisasignificantpositivecorrelationbetweenrootsoilpHandseleniumenrichmentcoefficientoftea(r=0.87,p<0.05),andasignificantpositivecorrelationbetweenorganicmatterofrootsoilandSecontentoftea(r=0.91,p<0.05),andasignificantnegativecorrelationbetweenheavymetalelementssuchasCr,As,HgandNiinrootsoiland资助项目：福建省地质矿产勘查开发局地勘费项目“福建省泰宁县朱口镇1:1万农业地质调查评价”。收稿日期：2022-10-13作者简介：吴长锋（1989-），男，工程师...
