微量元素与健康研究

用新极谱法测定喷施硒叶面肥的农作物含硒量。研究了喷施硒叶面肥后，不同地点、品种、生长期农作物及其部位的含硒量。其中，粮食作物比对照增加３～３２倍，水果增加２～４倍，蔬菜增加７～６０倍。随生长期的延长，农作物含硒量不断增加。不同部位含硒量的顺序为：叶＞茎＞花＞果。喷施次数增加，农作物含硒量也随之增加。

This paper determines the content of element Se in crops by the method of New polarography After having sprinkled,we tested the cntent of the element Se in the crops at different places,of different kinds,during different periods of growing and in their diferent parts.The test proved that the grain increased by 3～32times,the fruit-2～4times and the vegetable-7～60times.With the elongating of the growing period,the content of the element Se incrops in creases constantly.The order of the content of the element Se in the different parts of crops is follows:leaf>stem>flower>fruit.With the increase of times of sprinkling.the content of the element Se raises constantly.
