| 中文摘要: |
| 不同磷基环境（TSP、PR、TSP 和PR1颐1 混合及空白）下生长的小白菜和芥菜对土壤中铅污染的修复试验
结果表明、对比空白组、磷基条件下的蔬菜体内铅含量及土壤中残留态铅含量均不同程度的降低；经过TSP 处理的
小白菜和P+T 处理的芥菜地上部分降低最多、分别为43.8%和53.4%。植物生长过程中其他离子的协同作用及有机
态铅的大量积累导致概况铅的含量较空白组大。结果还表明、在磷含量充足的条件下、TSP 处理能有效降低生物和土
壤铅毒性、对铅的修复具有重要的作用。 |
| 英文摘要: |
| The repair effects of Chinese cabbage and mustard grow in different phosphorus-compounds (TSP, PR, and
1颐1 TSP and PR) on the lead-contaminated soil were examined The results show that the contrast blank group, under the
conditions of phosphorus-based vegetable content of lead in the body and soil lead content were significantly lower in the
residual fraction. After the TSP processing cabbage and P+T handle mustard aerial parts reduce up to 43.8% and 53.4%,
respectively. The synergistic effect of other ions and organic lead massive accumulation of lead in the process of plant
growth profile lead content than the blank group. The results indicate that, under the condition of sufficient phosphorus
content, TSP treatment can effectively reduce the toxicity of biological and soil Pb having an important role in repair of
lead. |
