本文对国内外玉米的研究概况进行综述,并通过试验对阿图什、阿克苏所产的玉米,用原子吸收方法研究比较两地玉米中的微量元素铁、锰、铜、锌的含量。结果表明,阿图什所产玉米中的铁、锰、铜、锌含量分别为133.370 1μg/g、6.302 2μg/g、1.410 1μg/g、14.479 3μg/g。阿克苏所产玉米中的铁、锰、铜、锌含量分别为30.219 5μg/g、5.238 6μg/g、1.505 8μg/g、14.139 9μg/g。其中铁的含量差异比较大。
This paper reviews the research status of maize at home and abroad, and compares the contents of trace elements such as iron, manganese, copper and zinc in corn from Atushi and Aksu by means of atomic absorption. The results showed that the contents of iron, manganese, copper and zinc in Artush were 133.370 1μg / g, 6.302 2μg / g, 1.410 1μg / g and 14.479 3μg / g, respectively. The contents of iron, manganese, copper and zinc in the corn produced in Aksu were respectively 30.219 5μg / g, 5.238 6μg / g, 1.505 8μg / g and 14.139 9μg / g. The content of iron is quite different.
