| 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 Lyeium barbamm, 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, barbarum fruit was affected for selenium analysis, the selenium content between the 0.17-3.34 taking mg/kg, Lycium 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 Lyeium barbarum by application of sodium selenite. Drying process was no significant effect on the selenium content in Lycium barbarum. |
