[Methods] Four kinds of crops （tomato, leaf mustard, peanut, and carrot） were exogenous selenium fertilizer treated, to explore the selenium-enriching effects on these crops. [Results] Exogenous application of microbial nano-selenium can significantly increase the selenium content of the crops, of which the effects on big tomato （Weiyanuo） were the best. After spraying, the selenium content increased by 1.39 times, and at the same time the sugar content of tomato was also increased. [Conclusions] This study is expected to provide references for increase of the selenium content of agricultural products.展开更多
