Summary: | 碩士 === 國立雲林科技大學 === 環境與安全衛生工程系 === 103 === Farmland long cited heavy metal pollution of water for irrigation, cause Taiwan's farmland by range a wide range of heavy metal pollution.
In recent years, we observed that the Bidens pilosa var. radiate can found traces of heavy metal contamination in farmland, and can bloom throughout the year, distributed throughout the island at low altitude, is extremely easy to grow, so hope can be Bidens pilosa var. radiate features, the removal of heavy metals contaminated soil.
The experiment consists of seeds begin to nurture and heavy metal toxicity tests, experiments recorded during the observation of plant growth scenario and after the experiment analysis plants cumulative capacity of heavy metals, and calculate its growth quality, assess Bidens pilosa var. radiate and existing Vegetation Restoration Costs and processing speed differences.
From the experimental results that the majority of the amendments in seeds do not germinate with a, Bidens pilosa var species so strong it can not germinate in scheduled to revise soil regulatory standards, but predetermined relax scheduled to revise soil regulatory standards, it is also worth to explore. From the experimental results was found that Bidens pilosa var. radiate zinc metal has the ability to processed of zinc metal. The experiment did not also investigate the different stages of growth for the efficiency of Bidens pilosa var. radiata absorption of heavy metals research, future can add the various stages plant efficiency for the absorption of heavy metals with analyzed and discussed.
Keywords:Bidens pilosa var. radiata, Vegetation Restoration.
