Abstract
- The stress effect of cadmium absorption between aloe and Brassica junica was studied through a simulation experiment with different cadmium contents in soil. The results showed that the growth characteristics, biomass and cadmium content of aloe and B. junica plants were related to pH and cadmium content in the soil. When aloe was intercropped with B. junica, soil pH was higher than that of single planting, showing that intercropping aloe and B. junica can reduce aloe's absorption of Cd. When Cd content in the soil was high, the absorption coefficient of aloe was lower than that of B. junica, and Cd content in the leaves of intercropped aloe was 15.8%-79.2% lower than that of aloe cropped only. In addition, planting B. junica in the soil with different contents of Cd had certain stress effect on aloe's absorption of Cd, thereby protecting aloe well, improving safety of aloe planting and showing its potential tor application in phytoremediation.
