Stress Effect of Cadmium Absorption between Aloe and Solarium nigrum L.

The stress effect of cadmium absorption between aloe and Solarium nigrum L was studied through a simulation experiment with different cadmium contents in soil. The results showed that the growth characteristics, biomass and Cd content in the plants of aloe and S. nigrum L were closely related to Cd content in the soil, and S. nigrum L and aloe had a strong tolerance to Cd in the experiment. pH of rhizosphere soil with S. nigrum L and aloe planted was generally higher than that of non-rhizosphere soil, which is related to the planting pattern. Compared with aloe, S. nigrum L had a stronger capacity to accumulate Cd, and intercropping S. nigrum L and aloe could inhibit aloe's absorption of Cd, which is favorable to the sate planting of aloe. In addition, S. nigrum L has the potential to restore polluted soil. [ABSTRACT FROM AUTHOR]
