摘  要:
对营养液栽培1个月后的10种植物用88Sr和133Cs进行处理,1周后收获并分析其对88Sr和133Cs的富集能力。结果表明:88Sr在10种植物的地上部含量顺序为苕子>孔雀草>蚕豆>豌豆>金盏菊>瓜叶菊>油菜>地被菊>大豆>石竹,孔雀草和蚕豆的地上部88Sr含量大于根系,其余植物富集的核素88Sr大部分都积累在根部。133Cs在10种植物的地上部含量顺序为孔雀草>金盏菊>瓜叶菊>地被菊>石竹>油菜>豌豆>苕子>蚕豆>大豆,石竹和地被菊地上部133Cs的富集系数大于1。说明它们能把吸收的88Sr或133Cs较多地运输到地上部,其体内可能存在良好的运输机制,有待进一步研究。

摘  要:
To delect the plants which can accumulate 88Sr and 133Cs,the uptake and accumulation of 5 green manures and 5 flowers were investigated under hydroponic conditions.The results were as follows: the concentrations of the leaf and stem of 88Sr in ten plants:Vicia dasycarpa Tenore>Tagetes patula>Vicia faba Linn>Pisum sativum Linn>Calendula officinalis>Cineraria cruenta>Brassica campestris L>Tagetes patula>Glycine max(L.) Merr>Dianthus chinensis L the concentrations of abovegroud parts of Maidenhair and Horsebean were greater than that in the roots,the concentrations of 88Sr of other plants were accumulated in the roots.The concentrations of the leaf and stem of 88Sr in ten plants:Tagetes patula>Calendula officinalis>Cineraria cruenta>Tagetes patula>Dianthus chinensis L>Brassica campestris L>Pisum sativum Linn>Vicia dasycarpa Tenore>Vicia faba Linn>Glycine max(L.) Merr.The bioaccumulations coefficients of 133Cs in abovegroud parts of Pink and Blackeyed Susan were not less than uptake of 88Sr and 133Cs was transported above groud parts,the substancesin of plants maybe exict the good transportiong mechanisms,we need investigate furtherly.
