采用微波消解电感耦合等离子体-原子发射光谱法对黄瓜果实膨大生长过程中的矿质元素B、Ca、Cu、Fe、K、Mg、Mn、zn含量进行了测定,分析结果的相对标准偏差为0.22%-6.02%.该方法简单、快速、可靠、灵敏度高,且多元素可以同时测定,能满足实际样品分析需要.实验表明,在黄瓜果实膨大生长过程中,矿质元素的含量发生了显著变化,但整体上都呈下降趋势.在整个果实膨大过程中,Ca、K、Mg含量最高,Cu、Mn含量最低.该研究结果为今后深入研究矿质元素与果实膨大生长的相关性提供了理论依据.

Microwave digestion technique was used in the digestion of cucumber fruits of expanding growth, and the contents of B, Ca, Cu, Fe, K, Mg, Mn and Zn were determined by inductively coupled plasma-atomic emission spectrometry(ICP-AES).The relative standard deviations for all these elements in this method were between 0.22% and 6.02%.This method was proved to be simple, rapid, reliable, and highly sensitive.In addition, the determination of these mineral elements can be carried out at the same time, which can meet the requests of actual sample analysis.The experimental results shows that the contents of mineral elements are decreased in the process of expanding growth of cucumber fruits, the contents of Ca, K, Mg are higher than others, and the contents of Cu, Mn are lower.The results will provide scientific basis for deeply study of the relation between the mineral elements and the expanding growth of cucumber fruit.
