| 摘 要： | 通过对日照市绿茶产区地质、地球化学环境的系统分析，认为地形、地貌、土壤理化性质和元素含量等对茶叶的品质具有重要影响。土壤元素全量与茶叶的相关性并不好，但其有效含量的丰缺情况对茶叶品质有较大影响，当土壤中速效N、SiO2含量较高时，茶叶中游离氨基酸、咖啡碱、总灰分含量也会比较高，茶叶品质相对较好；当土壤pH值及Ca、Mg有效含量较高时，茶叶中游离氨基酸、咖啡碱、总灰分、黄酮的含量反而会较低，从而降低茶叶的生化品质。该研究成果为日照绿茶产地规划与南茶北引提供了科学依据。 |

| Abstract: | Based on a systematic analysis of geological and geochemical environment of Rizhao tea-producing area, the authors hold that terrain, geomorphology, soil physical and chemical properties and elements content have important effects on tea quality. The cor- relation between total soil elements quantity and tea quality is not obvious, but the abundance and deficiency of effective elements have great impact on the tea quality. When the content of the available N, SiO2 is relatively high, he content of free amino acids, caffeine and total ash in the tea will be higher, and the tea quality will be also higher. When the pH value of the soil and the effective content of Ca, Mg are comparatively high, the content of free amino acids, caffeine and total ash, and flavonoids in the tea will decrease, and the quality of the tea will also decrease. The correlation between water extracts and most effective elements is relatively obvious. The results obtained by the authors provide the basis for programming of Rizhao green tea producing area and south-to-north tea transfer. |
