Rape is the main vegetable oil raw material and has a large planting area. It is of great significance to study the effect of selenium on rape. The purpose of this study is to find the effects of selenium on rape seed germination and its physiological and biochemical indexes, in order to find a feasible way to increase rape yield. In this paper, a comparative experiment was conducted to study the effect of different concentrations of selenium solution on rapeseed biomass, so as to achieve the research purpose. This study found that soaking seeds with a certain concentration of selenium solution is conducive to improving the germination rate and germination potential of the seed, especially when treated at a concentration of 15-25 μg / ml, selenium can promote the germination of the seed, in the range of selenium mass concentration less than 20 μg / ml With the increase of selenium mass concentration, the reduction rate of rape root system increased, and the selenium mass concentration was too high. When the selenium mass concentration was more than 20 μ / ml, the reduction rate of rape root system decreased, and it can be seen that high-quality selenium inhibited the growth and development of the root system. Therefore, supplementing appropriate amount of selenium can promote the growth and development of rape, which is beneficial to improve the growth environment of the root system, improve reducing power, increase biomass, and properly supplement selenium in rape cultivation to improve selenium nutrition of rape and promote growth and development of rape., Thus increasing yield, improving quality, etc. will have an impact.
