摘    要:对‘射手101’、‘大像生一号’、‘美国大速生’3种叶用莴苣的富硒效果进行比较。分别采用叶面喷施浓度梯度为7.5、15.0、22.5 g/hm2的硒酸钠与亚硒酸钠溶液,进行1次或2次叶面喷施,利用原子荧光光谱仪标准曲线法测量硒含量。结果显示:不同浓度的2种硒源均可以提高3种叶用莴苣含硒量。其中,浓度为22.5 g/hm2的亚硒酸钠富硒效果最好。喷施1次,‘射手101’效果最佳,含硒量为(11.33±1.52753) μg/100 g。喷施2次,‘大像生一号’效果最佳,含硒量为(14.33±0.5774) μg/100 g,约为喷施1次时含硒量(4.87±0.3215) μg/100 g的3倍。

Abstract:In this study, the effects of selenium enrichment on three kinds of leaf lettuce were compared. To observe the selenium-enriched influence on ‘ Sheshou101', ‘ Daxiangshengyihao',‘ Meiguodasusheng', the content of selenium was measured by atom fluorescence spectrometer standard curve after the leaf lettuce was sprayed sodium selenate and selenite once or twice respectively with a series of gradient concentrations of 7.5, 15.0, 22.5 g/hm2. The results showed that 2 kinds of selenium source with different concentrations all can increase selenium content of 3 kinds of leaf lettuce. Of all the concentrations of both selenium sources, 22.5 g/hm2 of sodium selenite led to the best selenium-enriched effect. In once-spaying test, (11.33± 1.5275) μg/100 g selenium content on ‘Sheshou 101' resulted in the best selenium-enriched effect, while (14.33 ±0.5774) μg/100 g on ‘Daxiangshengyihao' contribute to the best in twice-spraying test, 3 times higher than (4.87±0.3215) μg/100 g after spraying once.
