富硒大豆的研究

Study on rich-seleniumed soybean

通过盆栽和田间试验,研究肥料中硒的含量和大豆硒的积累特性.结果表明,施用研制的硒矿粉速效肥,土壤中硒质量分数为2mg kg时,大豆产量高,硒含量也较适宜.大豆中硒的积累与土壤中硒的含量有关,随着土壤中硒含量的增加而递增,但土壤中硒含量过高也会影响大豆的产量.

Studies the special features of selenium amount in fertilizer and the accumulated selenium soybean by separately planting soybean in basins and in fields. The results showed that by employing the fast effect fertilizer developed from selenium mineral powder, when the selenium concentration in soil is 2 mg/kg, the output of soybean is fairly high; the amount of selenium is comparatively good. The accumulation of selenium in soybean is related to the amount of selenium in soil. The accumulation will increase as the amount of selenium in soil goes up. But the excessive amount in soil will influence the output of soybean.
