海南油茶品质独特，随着大众对生活品质与营养健康的日益重视，以及市场对食品安全监管力度的持续加大，深入分析海南油茶主产区林地土壤特征及其对油茶籽元素组成的影响，可充分揭示海南油茶籽的安全性。本研究在海南油茶主产区共选取11个样地，测定土壤pH、养分含量（包括有机碳、有机质、全氮、全磷、全钾、硝态氮、铵态氮、碱解氮、有效磷、速效钾、缓效钾）及重金属元素（铜、锌、铅），并同步测定油茶籽中氮、磷、钾、全钙、全镁、全铜、全锌、铅等元素的含量。采用Duncan多重比较法分析各指标和富集系数的差异，通过Pearson相关分析与Mantel检验，分析土壤对油茶籽元素的影响。结果表明，海南油茶主产区土壤呈强酸性至弱酸性（pH 3.83~6.90），养分空间异质性显著。DA-1样地的有机质、BT-1样地的氮、HK-1样地的全磷与速效钾、QH-2样地的有效磷含量最高；HK-1样地的Cu、Zn及DA-2样地的Pb含量较高。油茶籽中7种营养元素含量差异极显著（P<0.01），其中全钙的变异系数最大（41.2%），HK-1（大量元素富集型）、QH-2（微量元素优势型）、QH-1（综合均衡型）及DA-1（高蛋白-微量元素协同型）为优质资源类型。元素富集系数呈现明显样地特异性，WZS-1（磷）、QH-2（钾）、DZ-1（铜）及CM-1（氮、锌）表现突出。相关性分析证实：土壤pH与油茶籽镁、钾积累呈极显著正相关，有机质与籽粒铜含量强关联，有效磷与钙、锌含量呈显著正相关。表明维持土壤微酸至中性、增施有机肥并平衡磷肥是提升海南油茶籽营养品质的关键措施。本研究为优质油茶籽资源筛选、定向栽培及加工产品品质优化提供理论依据。

Camellia oleifera from Hainan possesses unique quality traits. Public attention to both quality of life and nutritional health is increasing, while market oversight of food safety is being continuously strengthened. An in-depth analysis of the soil characteristics in the forestlands of Hainan's main C. oleifera planting regions and the impact on the elemental composition of the seeds can fully reveal the safety attributes of Hainan C. oleifera seeds. In this study, a total of 11 sample plots were selected from the main C. oleifera planting areas of Hainan. Soil pH, nutrient contents (including organic carbon, organic matter, total nitrogen, total phosphorus, total potassium, nitrate nitrogen, ammonium nitrogen, alkali-hydrolyzable nitrogen, available phosphorus, rapidly available potassium, and slowly available potassium), and heavy metal elements (copper, zinc, and lead) were measured. Simultaneously, elemental indicators in C. oleifera seeds, including nitrogen, phosphorus, potassium, total calcium, total magnesium, total copper, total zinc, and lead, were determined. Duncan's multiple range test was employed to analyze the differences among various indicators and translocation factors. Pearson correlation analysis was used to examine the influence of soil properties on seed elements. The results indicated that the soils in the main C. oleifera planting areas of Hainan Island ranged from strongly acidic to weakly acidic (pH 3.83-6.90), with significant spatial variation in nutrient content. The DA-1 plot had the highest organic matter content; BT-1 had the highest total nitrogen; HK-1 had the highest total phosphorus and available potassium; and QH-2 had the highest available phosphorus. Notably high levels of copper and zinc were found in the HK-1 plot, while the DA-2 plot exhibited elevated lead content. The contents of the seven nutrient elements in C. oleifera seeds differed extremely significantly (P<0.01), with total calcium showing the largest coefficient of variation (41.2%). Four sample plots, HK-1 (enriched in macronutrients), QH-2 (advantageous in micronutrients), QH-1 (comprehensively balanced), and DA-1 (exhibiting high protein-micronutrient synergy), were identified as high quality resources. The elemental enrichment factors exhibited pronounced plot-specific characteristics, with WZS-1 (for phosphorus), QH-2 (for potassium), DZ-1 (for copper), and CM-1 (for nitrogen and zinc) showing outstanding performance. Correlation analysis confirmed that soil pH was highly significantly positively correlated with the accumulation of magnesium and potassium in C. oleifera seeds, organic matter was strongly associated with seed copper content, and available phosphorus showed significant positive correlations with calcium and zinc contents. This study reveals that maintaining slightly acidic to neutral soil, increasing organic fertilizer application, and balancing phosphorus fertilization are key measures for enhancing the nutritional quality of C. oleifera seeds in Hainan. It would provide a theoretical basis for the selection of high-quality seed resources, targeted cultivation practices, and the optimization of processed product quality.
