Abstract
In the pot experiment, the simulation of sewage irrigation was carried out to study the cadmium pollution to rape, and the application effect of selenium as alleviant on rape biomass and cadmium accumulation in rape and soil. The results showed that the pollution of cadmium to rape could be alleviated to a certain degree by selenium. Compared to the check, the rape grew better when irrigated with low concentration of cadmium, but grew the worst when irrigated with high concentration of cadmium. The cadmium content in soil and rape increased with the increasing of cadmium concentration. Within a certain range, the alleviation effect on cadmium pollution to rape improved with the increase of selenium content, while that to soil did not change significantly. When the concentration of selenium was 0. 5 mg/L, the cadmium content in rape decreased by 28.05% (lowCd) and 31.09% (highCd) respectively.关键词
