摘要:
福建省是中国杨梅重要产地,其中龙海市浮宫杨梅因其独特品质而名扬海外,是当地的名特优农产品。以龙海杨梅产地为研究区,系统采集了35套岩石-土壤-杨梅果实样品,测定了主量组分、植物营养有益元素、有害元素以及土壤部分营养元素有效态含量。研究表明:受地质背景影响,浮宫镇及其周边杨梅产地土壤中植物营养有益元素的有效度及其有效量普遍高于东泗镇,而有害元素含量较低,为浮宫杨梅的优质高产、富硒杨梅产出提供了地质地球化学条件;土壤中植物营养元素P、Mn、Cu、Zn、S有效态含量与其全量显著正相关;研究区岩石、土壤Se含量均远高于全国平均水平,采集的35件杨梅果实样品富硒率高达74.3%;植物营养有益元素的富集系数明显高于有害元素,显示出杨梅对营养有益元素的选择性吸收以及对有害元素的阻遏作用。

Abstract:
Fujian Province is an important producing area of bayberry in China. Fugong bayberry, known overseas for its unique quality, is a high quality agricultural product. The main production area of bayberry in Longhai was selected for this study. Rocks, soils and fruits were sampled from this area, and the values of their main components and beneficial-nutritional as well as harmful elements were determined. The authors also measured the available values of some nutritional elements. Some conclusions have been reached:(1) The content of beneficial-nutritional elements is higher in Fugong Town than that in Dongsi Town. On the contrary, the content of harmful elements in the Dongsi Town is relatively higher than that in Fugong Town; (2) there is a certain correlation for the composition of elements between rocks, soils and fruits, reflecting the impact of geological setting on geochemistry; (3) the available values of P, Mn, Cu, and Zn have significantly positive correlation with their total content; (4) the content of Se in rocks and soils in the study area is obviously higher than the national average level, and the rate of Se-enriched is up to 74.3% for 35 bayberry fruits; (5) the Transfer Factor (TF) of beneficial-nutritional elements is significantly higher than that of harmful elements, indicating bayberry's active selective uptake of beneficial-nutritional elements and inhabitation of the intake of harmful elements.
