| 摘 要： | 为了解洛阳市小麦籽粒元素富集特征基于土壤元素含量的关系，对洛阳市土壤硒高背景区种植的小麦和土壤进行了系统采集，测定了土壤25项全量指标、6种元素的有效态指标、7种元素的形态指标及小麦籽粒12种微量元素含量，分析了土壤和小麦籽粒中有益元素和重金属元素的含量特征、富集规律以及小麦籽粒微量元素与土壤元素的相关性。结果表明，研究区土壤富集硒和钼，小麦籽粒中钼、锌、硒、铜的富集系数均大于15%，富硒小麦的比例为69.11%，籽粒镉、砷、铅、汞、铬含量均低于全国平均值。小麦籽粒中硒、钼、砷含量与土壤pH值均呈显著正相关，镉、铬、镍含量与土壤pH值均呈显著负相关，锗含量与土壤pH值呈正相关，铜、锌含量与土壤pH值呈负相关，汞、铅、氟含量与土壤pH值均无相关性。研究区小麦籽粒具有有益元素丰富、有害元素含量低的特征，因而该地区是富硒富钼同时锌铜丰富的特色小麦有利地区。

| Abstract: | In order to understand the element enrichment characteristics of wheat grains in Luoyang, the wheat and soil samples in the high selenium area were collected systematically, and 25 total indices of soil, the effective state indices of six elements, the morphological indices of seven elements and the contents of 12 trace elements in wheat grains were determined. The content characteristics and enrichment rules of beneficial elements and heavy metals in soil and wheat grains were studied, and the correlation between the trace elements in wheat grains and the elements in soil was summarized. The results showed that the soil in the study area was enriched with selenium and molybdenum, the enrichment coefficient of molybdenum, zinc, selenium, and copper in wheat grain was more than 15%, the selenium enrichment rate of wheat was 69.11%, and cadmium, arsenic, lead, mercury, and chromium were lower than the national average. According to the correlation analysis of elements, selenium, molybdenum, and arsenic in wheat grains are significantly positively correlated with pH, but cadmium, chromium, and nickel are significantly negatively correlated with pH; germanium is positively correlated with pH; copper and zinc are negatively correlated with pH; mercury, lead, and fluorine have no correlation with pH. Wheat grains in the study area are rich in beneficial elements and low in harmful elements, indicating that the study area is a favorable area for developing characteristic wheat enriched with selenium, molybdenum, zinc, and copper. |
