| Abstract: |
| A pot experiment was conducted to investigate the effects of different fertilizers on the growth, cadmium(Cd) accumulation and distribution in Chinese Flowing Cabbage(Brassica campestris L. ssp.chinensis var.utilis) Cultivar Youlv-80d-choy sum(Y80) and Teqing-60d-choy sum(T60) cultivated in Cd contaminated soil. Result showed that the increase of soil Cd content raised the concentration of Cd in rhizosphere soil, root, stem and leaf of the two cultivars. With the increase of soil Cd, the plant growth were also further inhibited. However, the biomass of Cultivar Y80 was significantly greater than that of T60. Under different fertilizer treatment, the range of Cd absorption in the edible part of these two cultivars from low to high was:chicken manure fertilizer >silicon magnesium fertilizer >bio-chicken manure fertilizer >compound fertilizer. The concentration of Cd in edible part was the lowest in the treatment of chicken manure fertilizer and then the second lowest was in treatment of silicon magnesium fertilizer. They both significantly lower than that in treatment of compound fertilizer. The concentration of Cd in stem and leaf was 46.19% lower in Cultivar Y80 than in Cultivar T60 on average. In chicken manure fertilizer treatments, the Cd content in stem and leaf was even 56.05% lower in Cultivar Y80 than in Cultivar T60. The biomass yields of Y80 were 33.53%~61.49% more than Cultivar T60. In chicken manure fertilizer treatments, the enrichment rates were from 0.77 to 1.1 for Y80 and from 2.07 to 2.26 for T60 and the transfer rate of Cd were from 0.96 to 1.24 for Y80 and from 1.99 to 2.89 for T60 in the treatments of chicken manure fertilizer. So the Cultivar Y80 is more suitable than Cultivar T60 for production in Cd contaminated soil. Chicken manure fertilizer is important to control the vegetable contamination for these two cultivars in Cd contaminated soil. |
