Abstract
By pot rice experiments, 3 kinds of rice including Boyou 998, Qiuyou 998 and Jindaoyou 998 were planted in the natural Selenium-rich soils with high Se concentration and low Se concentration respectively. The results indicated that positive correlation was found between Se content in the rice grains and that in the soils. However, the yield of rice grains decreased when Se content in the soils was in a high level. After addition of Cd, the results showed that the content of Cd in the rice grains of Boyou 998, Qiuyou 998 and Jindaoyou 998 planted in the natural Se-rich soils in a high level was reduced by 26.99%, 10.28% and 13.48% respectively compared to those planted in the natural Se-rich soils in a low level, which indicated the antagonism of appropriate amount of Se in the soils towards Cd absorption. Moreover, Qiuyou 998 had the strongest enrichment of Se and Cd but with lowest yield. Jindaoyou 998 had a certain effect on Se collection but with lowest collection capacity of Cd. However, the output of Jindaoyou 998 was higher. Therefore, when varieties were screened, priority should be given to Jindaoyou 998.关键词
