通过对大豆进行叶面喷施硒蛋氨酸的盆栽试验，发现能明显提高大豆籽粒硒水平，籽粒富集Se的能力约是对照的6倍，不同器官富集Se的规律为：叶＞粒＞茎＞壳，而其产量没有发生明显变化。大豆叶片吸收Cd， Pb的能力最强，其中叶片Cd含量为0.30～0.90 mg／kg， Pb含量为1.0～1.9 mg／kg，叶片Pb含量是籽粒的42～98倍。大豆植株里的Se对籽粒、壳、叶、茎等各器官吸收Cd、 Pb均表现出拮抗作用，对Cd的拮抗作用较强，对Pb的拮抗作用较弱。

By Spraying Selenium methionine on leaves of Soybeana and analysising Se , Cd, Pb content in different organs of soybean , It found that foliar application of Se can significantly improve Se level in grain , which was about 6 times of the seed with no spraying Se.Se-rich laws of different organs was leaf >grain>stem>shell, however the yield of soybean seed had no obvious diversification.Whether spraying se or no , the strongest ability of absorbing Cd , Pb was blades.Cd content of leaves was 0.30~0.90 mg/kg and Pb was 1.0~1.9 mg/kg.It was surprised that Pb content in leaves were 42 to 98 times of grain.Se showed antagonism on Cd and Pb in soybean seed , shell, leaf, as well as stem.The ability of antagonism on Cd was stronger than that of Pb.
