| 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。河南作为中国粮食主产区,根据河南省土地质量地球化学调查成果显示,农耕区表层土壤锌元素背景较高,但土壤酸碱度差异明显,探究土壤-小麦锌含量相关性,支撑富锌农产品开发具有一定的意义。本文利用土壤地球化学方法,研究不同土壤酸碱环境下土壤全量锌和有效锌的关系,以及土壤全量锌对小麦锌元素含量的影响,为进一步开发富锌土壤资源提供基础依据。本文通过在河南农耕区选择8处典型研究区,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、有机质含量利用Pearson相关分析。结果表明,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土壤全氮含量和有机质在碱性土壤条件下,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、酸性土壤中对于土壤锌元素与小麦锌富集影响均有不同的差异；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。研究发现,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,并适当施用氮肥、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 the growth and development of wheat, and it is crucial for the nutritional quality of grains and human health. As a major grain-producing area in China, according to the results of the geochemical survey of land quality in Henan Province, the background content of zinc elements in the surface soil of the farming areas is relatively high, but there are obvious differences in soil pH. Exploring the correlation between the zinc content in soil and wheat is of certain significance for supporting the development of zinc-rich agricultural products.In this paper, using soil geochemical methods, the relationship between the total zinc content and available zinc content in soils under different soil acid-base environments was studied, as well as the influence of the total zinc content in soil on the zinc content in wheat, providing a basic basis for the further development of zinc-rich soil resources. In this paper, by selecting 8 typical study areas in the farming areas of Henan Province, root soil-wheat samples were collected and analyzed collaboratively. The geochemical parameter statistics were carried out on the obtained data of the total zinc content, available zinc content in soil and zinc content in wheat, and Pearson correlation analysis was conducted in combination with the soil nutrient and organic matter content.The results show that: ① In alkaline soils, the average contents of total zinc, available zinc and zinc in wheat are relatively high, and wheat has a relatively strong ability to enrich zinc elements in the soil. Neutral soils rank second, and acidic soils have lower contents. ② Compared with neutral and acidic soils, under alkaline soil conditions, there is a significant correlation among the total zinc content, available zinc content and zinc content in wheat. ③ Under alkaline soil conditions, the content of total nitrogen in soil and organic matter have a relatively obvious effect on the enrichment of zinc elements in soil and the absorption of zinc by wheat. There are different differences in the influence on the enrichment of zinc elements in soil and zinc in wheat in neutral and acidic soils. The total phosphorus in soil has a relatively significant correlation with the total zinc content, available zinc content in soil and zinc content in wheat under neutral and acidic conditions. The total potassium in soil is only closely related to the total zinc content, available zinc content in soil and zinc content in wheat in neutral soils.The study found that the total zinc content, availability of zinc in the surface soil and zinc content in wheat in the farming areas of Henan Province are comprehensively affected by soil pH, soil nutrients and organic matter content. Alkaline soils are more suitable for the development of zinc-rich agricultural products, and appropriately applying nitrogen fertilizers and increasing the organic matter content can promote the absorption of zinc by wheat. The research results provide a scientific basis for the development of zinc-rich agricultural products in Henan Province. |
