| 中文摘要: |
| 锌是小麦生长发育必需的微量元素，对籽粒营养品质和人体健康至关重要。本文通过土地质量地球化学调查方法，在河南省选择8处典型农耕区，协同采集根系土-小麦样品并进行分析，对取得的土壤全量锌、有效锌和小麦锌含量数据进行了地球化学参数统计，并结合土壤养分、有机质含量进行相关分析。结果发现，(1)碱性土壤中全量锌、有效锌、小麦锌元素平均含量较高，小麦对土壤锌元素富集能力较强，中性土壤次之，酸性土壤较低;(2)碱性土壤较之中性和酸性土壤，碱性土壤条件下全量锌、有效锌、小麦锌含量相关性显著;(3)土壤全氮和有机质含量在碱性土壤条件下，对土壤锌元素富集及小麦对锌元素的吸收作用较明显，中性、酸性土壤中对土壤锌元素与小麦锌富集影响有所差异；土壤总磷在中性和酸性条件下与土壤全量锌、有效锌和小麦锌含量相关性较显著；土壤全钾仅在中性土壤中与土壤锌全量、有效锌和小麦锌含量关系密切。研究表明，河南农耕区表层土壤全量锌、有效性及小麦锌含量受土壤酸碱度、土壤养分、有机质含量的综合影响，碱性土壤中更适宜开发富锌农产品，适当施用氮肥、增加有机质含量可以促进小麦对锌元素的吸收。研究结果为河南省富锌农产品开发提供了科学依据。 |

| Zinc is an essential trace element for wheat growth and development and is crucial for grain nutritional quality and human health. In this paper, through the geochemical survey method of land quality, eight typical farming regions in Henan Province are selected, and root-zone soil-wheat samples are co-collected and analyzed. The geochemical parameter statistics are conducted on the obtained data of total soil zinc, available zinc, and wheat zinc content, and relevant analyses are combined with soil nutrients and organic matter content. The results show that: (1) The average contents of total zinc, available zinc, and wheat zinc in alkaline soils are higher, and wheat has a stronger ability to enrich soil zinc elements, followed by neutral soils, and lower in acidic soils. (2) Compared with neutral and acidic soils, the contents of total zinc, available zinc, and wheat zinc are significantly correlated under alkaline soil conditions. (3) Under alkaline soil conditions, soil total nitrogen content and organic matter has a more obvious effect on soil zinc enrichment and wheat absorption of zinc elements, while there are differences in the influence of neutral and acidic soils on soil zinc and wheat zinc enrichment; soil total phosphorus is significantly correlated with soil total zinc, available zinc, and wheat zinc content under neutral and acidic conditions; soil total potassium is only closely related to soil total zinc, available zinc, and wheat zinc content in neutral soils. The study shows that the total zinc content, availability, and wheat zinc content in surface soil of farming regions in Henan Province are comprehensively affected by soil pH value, soil nutrients, and organic matter content. Alkaline soils are more suitable for developing zinc-rich agricultural products, and the appropriate application of nitrogen fertilizer and increasing organic matter content can promote wheat absorption of zinc elements. The research results provide a scientific basis for the development of zinc-rich agricultural products in Henan Province. |
