本文研究了海南岛中部山区不同生境、不同品种的槟榔植株对6种金属元素的选择吸收积累和交换作用。结果表明槟榔植株对元素的吸收积累量、变化范围和交换作用差异明显 ,均为海南槟榔>云南槟榔>泰国槟榔 ;种间金属元素含量水平以A1>Zn>Cu>Ni>Mo>Pb为列 ;同种槟榔不同部位金属元素的吸收积累量差异程度不一 ;至于槟榔植株与土壤中元素的交换作用 ,以中北部沟谷产的槟榔吸收量 (127.25ug.g-1,48.44% )最高 ,东南部山地居中 ,西南部低丘偏低些。
In this paper, the selective absorption and exchange of six metal elements in different habitats and different varieties of areca plant in the central mountainous area of Hainan Island were studied. The results showed that there were significant differences in the uptake, accumulation and exchange of elements among the betel nut plants, all of which were betel nut of Hainan> betel nut of Yunnan> betel nut of Thailand. The contents of interspecific metal elements were Al> Zn> Cu> Ni> Mo> Pb ; The same amount of betel nut different parts of the absorption of metal elements vary in the degree of accumulation; As for the betel nut plant and soil elements in exchange for the production of betel nut in Central and Northern Gully (127.25ug.g-1,48.44%) highest, Southeastern mountain center, lower hilly southwest.
