摘要
从农业地质背景出发,论述了农业地质背景的作用机制及农业地质背景中元素的来源及元素的营养作用,并进一步以茶树为例,探讨了茶叶中微量元素与地质背景的关系。在此基础上,概述了贵州的地质环境条件及其与优质茶叶的关系。认为地质环境与茶叶品质的关系密切,是控制茶叶品质的先决条件之一。从农业生态地质的角度,不仅要研究第四系形成的最年轻的土层,而且必须研究成土母岩的地质环境,只有把地质背景与农业生态环境相结合,才能深入地研究地质环境与茶叶品质的关系,为茶叶规模化种植和优质茶叶种植提供科学指导。
The paper discusses the functional mechanism of agricultural geological background, source and nutritional role of the elements in agricultural geological background, and relationship between geological background and trace elements in tea, summarizes the close relationship between geological environmental condition and quality tea in Guizhou. The youngest soil of Quaternary System and the geological background of soil mother rock both should be studied from the angle of agricultural eco-geology at the same time. The relationship between geological environment and tea quality can be revealed by combining geological background with agricultural ecological environment to provide the scientific guide for tea scale cultivation and quality tea cultivation.
