以不同浓度硒溶液对枣树进行不同次数的叶面喷施,得到了不同硒含量的枣样品,用荧光光度法测定了样品中硒的含量。结果表明,与对照组相比,用外源性加硒法可明显提高枣中硒的含量;并且可通过调节喷施液浓度和喷施次数,得到硒含量适宜的成熟小枣。
以不同濃度硒溶液對棘樹進行不同次數的葉麵噴施,得到瞭不同硒含量的棘樣品,用熒光光度法測定瞭樣品中硒的含量。結果錶明,與對照組相比,用外源性加硒法可明顯提高棘中硒的含量;併且可通過調節噴施液濃度和噴施次數,得到硒含量適宜的成熟小棘。

Selenium (Se) content of jujube samples was determined by fluorescence spectrometry. Comparing with control group, Se content of jujube was obviously enhanced by different concentration of Se and different sprayed times. And Se content of jujube could be control according to the concentration and sprayed times for quantitative assimilate Se by human body.
