攀枝花钒钛矿区植物对钛的富集特性研究

Study on Ti Accumulation by Plants in the Panzhihua V-Ti Mining Area

通过野外调查采样,分析了四川省攀枝花市朱家包包钒钛矿区土壤的重金属含量,以及攀枝花市朱家包包钒钛矿区生长的20种植物体内Ti的含量,并初步研究了植物对Ti的富集特性。结果表明,20种植物体内Ti的含量都未达到超富集植物的标准。在这些植物中,12号植物地上部对Ti的富集量最高;蕨类植物地下部对Ti的富集量最高;紫荆泽兰的富集能力较强而且其转移能力也是最强的,可作为Ti元素的耐性植物进行更进一步的研究。

A survey was conducted in the Zhujiabaobao, Panzhihua V-Ti mining area of Sichuan Province to study heavy metal contents in soils and Ti contents in 20 species of plants. Primary study was conducted on accumulation of Ti in plants as well. The results showed that Ti contents in all 20 species plants were under the standards, of which the maximum Ti content for the plants overground part appeared in No. 12 and that for underground part appeared in pteridophyta. Besides, the enrichment capability of Crofton Weed was strong and as know, it has greatest migration capability, so it could be further studied as a Ti-resistant plant.
