富硒蔬菜及富硒机理研究进展

Research Progress on Selenium-rich Vegetables and Mechanism of Selenium-enriched

硒是人体不可或缺的营养元素,缺硒会引发多种疾病。利用蔬菜实现无机硒向有机硒的转化,从而提高食物中硒的含量,可以让人们在日常生活中提高硒的摄入量。该文阐述了土壤栽培富硒法、叶面喷洒富硒法、溶液培养富硒法和拌种富硒法4种蔬菜富硒方法的机理以及我国富硒蔬菜研究进展,以期为开发易被人体吸收利用的植物性富硒食品提供理论及实践指导。

Selenium is a necessary element in our body.Lacking of selenium will lead to various diseases.Vegetables can achieve the transformation of inorganic selenium to organic selenium and increase the content of selenium,which is the fundamental measure to improve body＇s health.At present,four major methods of selenium-enriched plant cultivation are available：soil cultivation,foliar spray,solution cultivation,and seed dressing.Basing on the mechanism of absorption and transformation of selenium in plants,this paper,briefly,introduces the solutions above and progress in research on selenium-rich vegetables.It will provide theoretical and practice guide for research of selenium-rich vegetables that is easily absorbed.
