Chinese Abstract

田間試驗結果表明,在低硒土壤上,施硒極顯著提高植株、子粒中的積硒量,增加幅度植株為夏大豆>秋大豆>春大豆,子粒為秋大豆>夏秋大豆>春大豆;並篩選出富集硒能力強的品種10份。在富硒土壤上種植的不同春大豆品種,植株、子粒硒積累量也存在顯著差異。在不同硒濃度條件下,同一大豆品種各生育階段硒積累量存在差異,其大小順序為成熟期>花期>苗期。施硒濃度以1.0mg/L單株積累量最高。

English Abstract

Field 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% (Na2SeO3) 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.
