摘    要:通过大棚盆栽试验研究在不同pH条件下,土壤中铅、镉、汞3种重金属的4个水平下蕹菜中重金属的累积特征.结果表明,在适宜的土壤酸度水平下,中低浓度的铅、镉、汞混合污染有利于蕹菜的生长;相反,在高浓度铅、镉、汞混合污染的碱性土壤中,蕹菜的生物量小,根茎短且易受病虫害危害;蕹菜是耐镉性植物,蕹菜中的镉含量易受到土壤中重金属含量...

关 键 词:pH值  重金属  Pb  Cd  Hg  蕹菜  累积特征

Abstract:Under the condition of different soil pH - value, the accumulation regularity of heavy metal in water spinach which was polluted by 4 levels of Pb, Cd and Hg in the soil was studied through pot experiments in plastic greenhouse. The results showed that the combined pollution of mid - low concentration of Pb, Cd and Hg was beneficial to the growth of water spinach in the soil with appropriate acidity. But under the conditions of the combined pollution of high concentration of Pb, Cd and Hg and alkali soil, the biomass of water spinach was small, its rhizome was short, and it was easily damaged by diseases and insect pests. Water spinach is cadmium resistant plant, and the Cd content in it was easily affected by heavy metal contents and pH -value in the soil.
Keywords:pH - value  Heavy metal  Pb  Cd  Hg  Water spinach  Accumulation character
