摘要
以宁夏枸杞品种＂宁杞1号＂为试材,选取宁夏中宁、银川园林场地区的枸杞,在其叶面喷施不同浓度硫酸亚铁、硫酸锌进行试验,利用高效液相色谱仪、原子吸收仪分析喷施对枸杞中有效成分及微量元素含量的影响。结果表明：在设定的铁0.05%-0.20%、锌0.05%-0.15%施用浓度范围,中宁、银川地区枸杞有效成分及微量元素积累趋势基本一致,均表现为随着施用浓度的增加,枸杞有效成分及微量元素均显著提高,到达一定量后,则随着施用浓度的增加,有效成分及微量元素含量呈下降的变化趋势,因此最适宜的喷施浓度为0.10%铁-0.05%锌。
Using Lycium barbarumvariety‘Ningqi No.1＇as the material,spraying sodium elements through leaf in two main regions of Ningxia Zhongning and Yinchuan.An atomic absorption and HPLC method has been developed for quantitative analysis.The results showed that：concentrations in the Fe 0.05%-0.20%,Zn 0.05%-0.15%,the active component and trace elements of Lycium barbarumsignificantly increased,taking Lycium barbarumfruit was affected for analysis,and the accumulation tendency was consistent in Zhongning and Yinchuan in Lycium barbarum.The final suitable determination concentrations were 0.10% Fe-0.05% Zn.
