To research the effect of how Se alleviate the harm brought by copper, we investigated the root length, stem, leaves, aberration by Cu colza in copper and Se-Cu compounds. The experimental simulation of sewage irrigation methods, the general consumption of rapeseed selected as experimental material, using the method of comparison, were dealing with a single copper, different concentrations selenium and copper concentrations were compared with experimental treatment. The Experiments were divided into three groups of treatment, respectively with a single copper, low concentrations selenium and copper and high concentrations of selenium and copper processing of rape. The focus is research the effect of selenium on the toxicity of copper. The result shows that the law of heavy metals like copper accumulation in the soil as well as in the migration and accumulation in rape and the law of metallic copper in the role of selenium in the soil accumulation as well as in the migration and accumulation in rape. The copper in the soil and rape are determinated by AAS. The results show that Selenium effectively alleviate the toxicity of copper on rape, and the ability of ease is high concentrations of selenium intensity than low concentrations of selenium.
