Effects of different phosphorus-compounds on heavy metal by plants

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.
