摘要/Abstract

摘要： 通过对廉江市杨桃( Averrhoa carambola) 绿色食品基地不同土质、不同树龄的土壤样品及果实样品重金属元素Cd、Hg、Cu、Pb、As、Cr 含量的检测, 分析杨桃果实对土壤重金属元素的吸收与富集作用。结果表明: ① 果园土壤pH≤5 . 50 , 为酸性土壤, 杨桃果园土壤和鲜果中的重金属含量均符合我国水果绿色食品生产的质量要求; ② 杨桃对土壤重金属的吸收因土壤质地和重金属元素的种类不同而异; ③ 杨桃对重金属元素的富集, 以Cd 元素为最强, 富集系数高达0 . 947 , 各种重金属的富集系数按大小排序为: Cd (0. 947) > Hg (0 . 098 ) > Cu (0 . 023) > Pb (0 . 003 ) > As (0 . 001) = Cr ( 0. 001) 。

Abstract: The soil heavy metal element absorption and enrichment of Carambola ( Averrhoa carambola ) were analied through the heavy metal elements content such as Cd , Pb , Cu , Hg , As, Cr of different types , different soil samples and different age trees of carambola in lianjiang green food base were investigated . The results showed that ① the soil pH≤5 . 50 which is acid soils and the heavy metal content of carambola orchard soil and fresh fruits were in conformity with the quality requirements of the production of green food; ② Heavy metal absorption carambola in the soil were different with the the different heavy metal element and different kinds ; ③ The enrichment of Cd was the most than other elements of heavy metals and the concentration coefficient was 0.947. According to the sequence as enrichment coefficients, the order was Cd (0 .947) > Hg ( 0. 098) > Cu (0. 023) > Pb (0 . 003) > As (0 . 001) = Cr (0 . 001) .
