摘要:

为了系统地研究宁夏枸杞硒的吸收富集规律,促进富硒枸杞安全生产,通过采用宁夏枸杞的主栽品种‘宁杞1号’为材料,在枸杞叶面施用亚硒酸钠,经枸杞树的吸收转化而形成富硒枸杞,利用原子荧光检测器进行定量分析。结果表明:设定的7个施硒浓度,在0.1~200.0 mg/kg之间,枸杞含硒量均有显著提高,取枸杞果实进行富硒效果分析,含硒量在0.17~3.34 mg/kg之间,线性关系良好(r=0.9992)。喷施浓度、次数是通过叶面喷施亚硒酸钠,生产富硒枸杞的关键因素,制干工艺对枸杞含硒量无显著影响。

Abstract:

In order to systematically study enrichment and absorption rules of Lycium barbarum, and promote the safety production, an atomic fluorescence method has been developed for quantitative analysis. Using Lycium barbarum variety ‘Ningqi No.1’ as the material, spraying sodium selenite through leaf, selenium-rich Lycium barbarum was formed by absorption and transformation. The results showed that: 7 Se concentrations in the 0.1-200.0 mg/kg between the Lycium barbarum selenium content significantly increased, taking Lycium barbarum fruit was affected for selenium analysis, the selenium content between the 0.17-3.34 mg/kg, and the linear relationship was obtained in this method (r=0.9992). Spray concentration, the number were the key factors of production of selenium-rich Lycium barbarum by application of sodium selenite. Drying process was no significant effect on the selenium content in Lycium barbarum.
