計畫中文摘要	植生復育(Phytoremediation)是利用植物來移除污染物的技術。因此本計畫擬利用本土種植物進行綠色復育試驗研究，以取得現地已污染含有重金屬鎘、鉻、銅的土壤作為植物種植的介質來源，目前規畫以本土常見與具有能源潛力作物，如狼尾草、台灣藜進行重金屬吸附試驗，待植物收成後除移除，亦可能作為生質能源作物料源來源。 從目前來看狼尾草所獲得的生物量最大，其次為台灣藜，狼尾草所獲得的生物量為台灣藜的3.53-4.28倍。在以不同養份處理量來看，狼尾草在施加不同比例養份，其生物量將較對照組提升1.29-2.21倍。而台灣藜在施加不同比例養份，其生物量將較對照組提升1.26-2.28倍。 而不同養份處理的環境下，狼尾草植體重金屬銅的濃度，對照組為42.10 mg/kg，隨著養份的增加，重金屬吸收為68.63 ~82.19 mg/kg，台灣藜植體重金屬銅的濃度，對照組為265.30 mg/kg，隨著養份的增加，重金屬吸收為337.45~377.64 mg/kg。狼尾草植體重金屬鉻的濃度，對照組為14.65 mg/kg，隨著養份的增加，重金屬吸收為38.20~44.36 mg/kg，台灣藜植體重金屬鉻的濃度，對照組為41.95 mg/kg，隨著養份的增加，重金屬吸收為55.20 ~64.15 mg/kg。狼尾草植體重金屬鎘的濃度，對照組為2.57 mg/kg，隨著養份的增加，重金屬吸收為3.93~4.81 mg/kg，台灣藜植體重金屬鎘的濃度，對照組為13.43 mg/kg，隨著養份的增加，重金屬吸收為17.27~20.11 mg/kg。 而不同養份添加EDTA後的環境下，狼尾草植體重金屬銅的濃度，隨著養份的增加，重金屬吸收為83.59~127.32 mg/kg，台灣藜植體重金屬銅的濃度，隨著養份的增加，重金屬吸收為416.55~447.77 mg/kg。添加EDDS後的環境下，狼尾草植體重金屬銅的濃度，隨著養份的增加，重金屬吸收為78.67~99.26 mg/kg，台灣藜植體重金屬銅的濃度，隨著養份的增加，重金屬吸收為351.54~437.79 mg/kg。 而不同養份施用量，對於植體吸收三種重金屬的效果都有上升趨勢，在重金屬鎘的效果較其他兩種重金屬銅及鉻來的較高。雖然對於植體內重金屬濃度效果較不顯著，但因生物量的增加，對於重金屬移除的總量將有助益。另以具有能源潛力的作物進行植生復育，對於環境永續上將具有一定的效益。
計畫英文摘要	Phytoremediation is a technique that uses plants to remove contaminants. Therefore, this project plans to use the local plant for green rehabilitation test study to obtain the pollution of the land containing heavy metals cadmium, chromium, copper soil as a medium for plant cultivation, the current planning to local common and energy potential crops, such as Pennisetum, Taiwan Chenopodium for heavy metal adsorption test, after removal of plants, but also as a source of energy for the source of raw materials. The biomass obtained from Pennisetum was the highest, followed by Taiwan quinoa, and the biomass obtained from Pennisetum was 3.53-4.28 times of Taiwan. In terms of different nutrient treatments, the biomass of Pennisetum was increased by 1.29-2.21 times compared with the control group. While Taiwan's quinoa in the application of different proportions of nutrients, the biomass will be higher than the control group 1.26-2.28 times. The concentration of heavy metal copper in the control group was 42.10 mg / kg, and the absorption of heavy metals was 68.63 ~ 82.19 mg / kg with the increase of nutrient content. The contents of heavy metal copper And 265.30 mg / kg in the control group. With the increase of nutrient content, the absorption of heavy metals was 337.45 ~ 377.64 mg / kg. The concentration of heavy metal chromium in the control group was 14.65 mg / kg, with the increase of nutrient content, the absorption of heavy metals was 38.20 ~ 44.36 mg / kg, the concentration of heavy metal chromium in Taiwan quinoa plant was 41.95 mg / kg, with the increase of nutrients, heavy metal absorption of 55.20 ~ 64.15 mg / kg. The concentration of heavy metal cadmium in the control group was 2.57 mg / kg, and the concentration of heavy metal was 3.93 ~ 4.81 mg / kg with the increase of nutrient content. The concentration of heavy metal cadmium in Taiwan quinoa was 13.43 mg / kg, with the increase of nutrients, heavy metal absorption of 17.27 ~ 20.11 mg / kg. The concentration of heavy metal copper in Pennisetum americana was 83.59 ~ 127.32 mg / kg with the increase of nutrient content, and the concentration of heavy metal copper in Taiwan quinoa was increased with the increase of nutrient content. The increase of heavy metal absorption is 416.55 ~ 447.77 mg / kg. In the environment of adding EDDS, the concentration of heavy metal copper in Pennisetum purpureum was 78.67 ~ 99.26 mg / kg with the increase of nutrient content. The concentration of heavy metal copper in Taiwan quinoa plant increased with the increase of nutrient, Heavy metal absorption was 351.54 ~ 437.79 mg / kg. The effect of different nutrient application on the absorption of three heavy metals in the plant is increasing, and the effect of heavy metal cadmium is higher than that of the other two heavy metals. Although the effect on the concentration of heavy metals in the plant is less significant, the total amount of heavy metal removal will be helpful due to the increase in biomass. Another with the potential of energy crops for plant regeneration, for the environment will have a certain degree of sustainable benefits.
