The main factor affecting the selenium content in plant is the content of effective selenium in soil. So it is important to understand the form and conversion relationship of selenium in soil and find ways to improve selenium effectiveness. By summarizing the researches on selenium at home and abroad,we analyze the classification of soil selenium form,the transformation among different selenium forms and the improving factors of selenium effectiveness. We understand the relationship between chemical form and extraction form of selenium,analyze the driving factors of conversion among different forms,and discuss the ways to improve selenium effectiveness of soil in high selenium-rich area. By combining characteristics of soil and crop in different selenium-rich regions,different selenium activation methods are used,which could provide more scientific evidence for further selenium research.展开更多
