摘　　要：田间试验结果表明 ,在低硒土壤上 ,施硒极显著提高植株、子粒中的积硒量 ,增加幅度植株为夏大豆 >秋大豆 >春大豆 ,子粒为秋大豆 >夏秋大豆 >春大豆 ;并筛选出富集硒能力强的品种 10份。在富硒土壤上种植的不同春大豆品种 ,植株、子粒硒积累量也存在显著差异。在不同硒浓度条件下 ,同一大豆品种各生育阶段硒积累量存在差异 ,其大小顺序为成熟期 >花期 >苗期。施硒浓度以 1Field experiment and solution culture were conducted to study the characteristic of selenium accumulation in different type soybean. The results showed that the selenium content and amount of accumulation in plant and grain increased significantly by spraying 0 025%(Na 2SeO 3) on leaves in three types of soybean, the increase range was summer soybean>autumn soybean>spring soybean in plant and autumn soybean>summer soybean>spring soybean in grain under low Se condition. The differences of Se accumulation in spring soybean varieties were also significantly under high Se condition. Solution culture with different Se concentration, the amount of Se accumulation in plant was various at different growth stage of soybean and the order was mature period>flowing period>seedling period. Application of Se with 1.0mg/L the amount of Se accumulation in spring soybean per plant was highest.10 varieties with high Se accumulation were selected.
