在对杞县大蒜产区的土壤及大蒜全面调查的基础上,探讨了土壤营养元素的地球化学特征、大蒜营养元素的生物化学特征、大蒜中营养元素含量与对应土壤全量元素含量及元素有效态含量的相关性、大蒜对营养元素的富集能力等问题,表明杞县大蒜产区土壤元素环境质量较好,元素有效态含量与全量元素含量具正相关性,可利用全量元素含量求解元素有效态含量;大蒜喜S、富Se,易开发为富Se食品。 Based on a comprehensive investigation of soil and garlic in the garlic production area of ​​Qi County, the geochemical characteristics of soil nutrient elements, the biochemical characteristics of garlic nutrient elements, the content of nutrient elements in garlic and the corresponding total soil element content and the effective element state Content of the garlic garlic on the enrichment of nutrients and other issues, indicating that garlic production in Qi County soil elemental environment is better, the effective element content and the total amount of elemental content is positively correlated, the total element content can be used to solve the element effective State content; Garlic Hi S, Se-rich, easy to develop foods rich in Se.
