采用硒硫二因素二次饱和D-最优设计进行烟草盆栽试验。结果表明，烟草各部位硒含量随施硒量的增加而增多，烟草生长前期根部硒含量高于地上部，成熟期烟叶和根部硒含量高于茎部，尤以上二棚烟叶硒含量最高。施硫对烟草硒的吸收和积累量的影响随烟草生育期、生长器官和硒硫浓度不同而异。前期烟草全株及地上部的硒积累量在低硫(＜75 μg*g－1)条件下随施硫增加而增多，硒硫表现为协同作用；在高硫(＞75 μg*g－1)条件下，烟草硒积累量则随施硫的增加而减少，表现为拮抗作用。不施硒时施硫会降低成熟烟叶硒含量，施硒时成熟烟叶硒含量则随施硫量的增加而增多，前者表现为硒硫拮抗作用，而后者则呈硒硫协同作用。

The Se and S pot experiment with flue-cured tobacco (Nicotina tabacum L.)was carried out using optimum design for two-factorial quadratic saturating D.The results showed that SeO2－3 application raised Se contents in different parts of tobacco.The contents of Se in tobacco roots at early growth were higher than those of Se in stalks and leaves,while the contents of Se in roots and leaves of tobacco at mature were higher than those of Se in stalks.The highest Se concentration appeared in upper leaves of tobacco.The infl uence of SO2－4 on the uptake and accumulation of SeO2－3 by to bacco changed with the growth period,organs of tobacco and the concentrations of added SeO2－3 and SO2－4.The Se accumulated amount of the stalks,leaves and total plant of tobacco at early growth stage raised with increasing of the SO2-4 application at lower S levels(＜75 μg*g－1)，sho wing the synergism interaction between Se and S;and while at higher S levels( ＞75 μg*g－1)the Se accumulated amount decreased with increasing of SO2－4,showing the ant agonistic interaction between Se and S.In the absence of added Se,SO2－ 4 application reduced Se contents of mature tobacco leaves and there was the ant agonistic interaction between S and Se in the uptake of Se by tobacco.In the pre sence of added Se,SO2－4 application increased Se contents of mature to bacco leaves,and there was the synergism interaction between S and Se in the uptake of Se by tobacco.
