Results showed that shoot biomass of H. annuus was significantly higher than that of R. acetosa and R. hastatus; among three plant species, 134Cs specific activity in shoots was the highest in H. annuus after 50 d-treatment, however after 70 d-treatment, that in R. acetosa was the highest. Bioaccumulation ratio reached 1.5, 1.4 and 1.3 in R. acetosa, R. hastatus and H. annuus after 70 d-treatment, and the former two plants kept with trend of continuously increasing. Three plants were resistant to 134Cs contaminated soil and capable of translocating 134Cs from soil to plants. Among them, H. annuus removed greatest 134Cs amount in the aboveground part during the experiment period, and R. acetosa, R.
结果表明,向日葵地上部生物量显著高于酸模和戟叶酸模;处理50d时,向日葵地上部134Cs比活度在3种植物中达到最高,而在处理70d时,酸模地上部134Cs的比活度达到最高;处理70d时,酸模、戟叶酸模和向日葵对134Cs的富集系数均大于1,分别达到1.5、1.4和1.3,且前2种植物继续保持快速上升的趋势。3种植物对铯污染土壤具有一定的忍耐性,并具有较强的从土壤向植物转移铯的能力;在本实验期内(70d)向日葵对土壤中放射性铯的剔除能力最强,而酸模和戟叶酸模则具有更强的铯转移能力。

Some primary beryl crystals are found in spodumene in zones Ⅲ and Ⅳ, and are enriched in Fe and Mg. The late secondary beryls with low contents of Cs2O are attributed to crystallization of pullucite and nanpingite. There is possibly a re-equilibrium between the late hydrothermal fluids and the Cs-rich beryl.
