土地复垦背景下重金属在小麦中的富集研究
首发时间:2009-08-17
摘要:采用盆栽试验,以小麦为受试作物,通过对成熟期各器官重金属含量的测定,研究了重金属Cu、Pb、Cd,Zn在成熟期小麦中的富集能力。以期为土地复垦后种植作物的安全性服务,研究结果表明:成熟期小麦根中富集能力是Cd>Pb>Cu>Zn,茎中富集能力Cd>Zn>Cu>Pb,叶片中富集能力是Cd>Zn>Cu>Pb,颖壳中富集能力Zn>Cd>Cu>Pb,籽实中富集能力是Zn>Cd>Cu>Pb。

Study on the enrichment of Heavy Metal in Wheat Crop under the background Of land reclamation
Abstract:With the test of growing plant with soil. the enrichment of heavy metal (Cu,Pb,Zn,Cd) in wheat were studied in maturity.The result shows that In adult stage the order of enrichmen factors in root is Cd >Pb>Cu >Zn;Cd >Zn>Cu >Pb in stalk, Cd>Zn>Cu>Pb in leaf, Zn> Cd> Cu>Pb in crust and Zn>Cd Cu> Pb in seed.
Keywords: growing plant with soil heavy metal wheat concentration factor
