根是茶树在地下的营养器官,与地上枝叶的生长有着密切的关系,要地上部枝叶茂盛,必须使根系有良好的生长。了解茶树根系的内部结构是研究茶树高产优质的生理生化的基础,本文研究不同树龄,不同部位根的结构特征,以便掌握其生长变化规律,为采取科学的栽培技术和耕作制度提供理论依据。 Root is a vegetative organ of tea in the ground, and the growth of branches and leaves on the ground has a close relationship to the branches of the aboveground leafy, must make the root system has good growth. Understanding the internal structure of tea tree roots is the basis for the study of high yield and quality physiological and biochemical characteristics of tea trees. In this paper, the structural characteristics of roots at different ages and different parts were studied in order to grasp the growth and variation rules and provide theoretical basis for adopting scientific cultivation techniques and farming systems.
