    摘要:

    本研究通过田间试验,测定不同花生品种的自然富硒能力及对外源硒的利用指数,然后通过施用外源硒,研究不同调控措施对花生籽粒硒含量及外源硒利用率的影响,为富硒花生生产提供技术参考。研究结果表明:自然条件下,12个花生品种春花生籽粒的硒含量在0.041 ~ 0.180 mg/kg,秋花生籽粒的硒含量在0.039 ~ 0.066 mg/kg,外源硒的利用指数为2.3 ~ 3.7。施用外源硒肥均能显著提高花生籽粒硒含量,含硒肥料基施、淋施和叶面喷施情况下,花生籽粒对外源硒的利用率分别为0.056% ~ 0.064%、0.23% ~ 0.25% 和3.74% ~ 4.99%。可见,不同花生品种间硒的富集能力和对外源硒利用能力均有差异,而叶面喷施的硒肥施用方式下花生对外源硒的利用率最高。

    Abstract:

    Field experiments were carried out in this study, selenium-enriched ability and exogenous selenium utilization index of difference peanut varieties were tested, and then the effects of different regulation and control measures on selenium contents and utilization rates of exogenous selenium in peanut seeds were studied through applying exogenous selenium to provide technical reference for the peanut selenium-enriched production. The results showed that under natural conditions, selenium contents in peanut seeds of 12 varieties ranged between 0.041–0.180 mg/kg in spring peanut, 0.039–0.066 mg/kg in autumn peanut. And exogenous selenium utilization index was 2.3–3.7. Applying the fertilizer containing selenium can significantly increase selenium content in peanut seeds, the exogenous selenium utilization rates of peanut seeds under applying fertilizers containing selenium as base fertilizer, drenching and spraying were 0.056%–0.064%, 0.23%–0.25% and 3.74%–4.99% respectively. Selenium-enriched abilities and exogenous selenium utilization capacities of different peanut varieties are different, and spraying fertilizer containing selenium has the highest utilization rate of exogenous selenium.
