摘要
En 中文
The Phyllostachys pubescens macrophyte, known also as Moso Bamboo, was evaluated in laboratory conditions for its potential to renovate copper-polluted soil. Pot experiments were conducted to determine Phyllostachys pubescens' growth, tolerance and phytoextraction potential capacity to restore copper-contaminated soil in Mediterranean conditions. Data collected evidenced that the Phyllostachys pubescens evolution rate was 0.47 cm/day on average, with a 1.644 mm/d irrigation flow. Moso Bamboo tolerance was tested over a twelve-week irrigation period, while adding copper-polluted water. Copper removal from soil was 51.4% and the quantity of copper per gram of root/rhizome was equal to 1.18 mg Cu/g, while the amount of copper per gram of stem/leaves was 0.50 mg Cu/g, after 12 weeks. The conducted laboratory experiments show that environmental restoration using the phytoextraction technique, and using Phyllostachys pubescens, should be considered for the restoration of copper-contaminated soils.
