针对锰矿矿渣土壤结构不良、养分少、重金属含量高的特点,及修复植物大多为草本植物的问题,在改良锰矿矿渣(对照CK: 100%矿渣+ 0. 1 kg磷肥;改良A: 80%矿渣+ 20%泥炭土+ 0. 1 kg磷肥;改良B: 70%矿渣+ 30%泥炭土+ 0. 1 kg磷肥;改良C: 60%矿渣+ 40%泥炭土+ 0. 1 kg磷肥)种植条件下,对湖南本土的14种木本植物进行耐性筛选,并对长势良好的耐性植物的亚细胞分布和化学形态进行了分析。结果表明: 1)植物长势、生物量、株高增量、重金属的吸收量及转移量系数均呈现改良组>对照组的规律,但改良组之间不同的植物品种存在差异,总体上泡桐、夹竹桃、栾树、乌桕表现出较好的耐性。2) Mn在泡桐、夹竹桃各部位...

In view of the poor structure, less nutrient and high heavy metal content of the manganese mine tailing slag and the plants for phytoremediation mostly are herbaceous plants, pot experiments with improved slag were adopted in this paper. Under the specific conditions （CK： 100% slag ＋0. 1 kg phosphate fertilizer, improved A： 80% slag ＋20% peat soil ＋0. 1 kg phosphate fertilizer, improved B： 70% slag ＋30% peat soil ＋0. 1 kg phosphate fertilizer, improved C： 60% slag ＋40% peat soil ＋0.1 kg phosphate fertilizer）, 14 species of woody pl...
