Selenium (Se) content in crop is one key factor affecting Se level in food chains. Based on the results of geochemical survey of soil environmental quality regarding crops and long-term positioning observation in Xunyu plain, Se accumulation characteristics of crops and influential factors were studied. Results showed that more than 86% of the rice were rich in Se in Qingtang, Gangnan, Guiping and Pingnan. In the studied area, the proportions of Se-rich peanut, soybean, corn and rice were 100%, 100%, 100% and 89%, respectively. Se bioconcentration factors of the root, stem, and grain of rice were 0.663, 0.130 and 0.108, respectively. Se bioconcentration factor of rice grain was much higher than those of longan, litchi and sugarcane. The correlation coefficient between Se contents in the rice grain and rice rhizosphere soil was 0.660, higher than those of longan and litchi. The correlation coefficient between Se contents in crops and soil pH was 0.342 in Gangnan. Se content in sugarcane stem (0.012 1 mg/kg) was higher in the alkaline soils than in other crops, whereas in the acid soils Se content in rice grain (0.065 3 mg/kg) was the highest among all the crops. These results indicated that the crops with seeds as edible part are generally rich in Se in the Xunyu plain, and Se content in rice is largely affected by soil Se content and pH.
