福建福州橄榄品质特征及其与地质背景的关系

Quality Characteristics of Fuzhou Olive and Its Relationship with Geological Background in Fujian Province

福州橄榄品种众多,其中惠圆、长营、檀香、梅埔二号和灵峰橄榄均为目前种植面积较大,且产量较高的主栽品种。各橄榄品种中总糖、总多酚、总黄酮、氨基酸、有机酸和含水率等橄榄品质特征均存在差异,尤其是决定橄榄鲜食品质的总糖和总多酚含量差异显著。地质背景对橄榄种植地土壤地球化学特征起着主导作用,是福州橄榄种植区立地条件的重要组成部分,不同地质背景中产出的橄榄果实品质差异较大。综合各类品质要素,区内火山熔岩区种植的橄榄综合品质最佳,部分侵入岩区产出橄榄综合品质也较高,其次为火山碎屑岩区,沉积岩区产出橄榄综合品质较一般。

Fuzhou olive have many kinds,among them,Huiyuan,Changyin,Tanxiang,MeipuⅡand Linfeng olive are the main variety with large planting area and high yield.The total sugar,total polyphenols,total flavonoids,amino acids,organic acids and water content are different among all kinds of olives,in particular,the content of total sugar and total polyphenols which determine the fresh eating quality of olive is significantly different.Geological background plays a leading role in soil geochemical characteristics,and it is an important part of site conditions in olive planting area in Fuzhou,the quality of olive produced in different geological background is quite different.Comprehensive various quality elements,the quality of olives planted in the area with volcanic lava geological background is the best,some olives planted in intrusive areas also have high quality,next is the volcaniclastic rock area,the comprehensive quality of olives planted in sedimentary rock area is of medium quality.
