氮素对茶树生理及品质成分影响的研究进展

Research Progress on Effect of Nitrogen on Physiological Metabolism and Major Quality-related Constituents in Tea Plants

氮素是茶树生长所必需的大量元素,决定茶叶的产量与品质。氮素的吸收、同化、转移、不同氮素水平的供应,以及不同形态氮素的供应都显著调节着茶树的生理代谢以及品质成分,此外氮素与其它多种营养元素的交互作用,也深刻影响茶树的生长发育,因此研究氮素对于茶树的影响具有现实的意义,本文结合我国近年来研究成果,系统综述了氮素对于茶树生理以及品质成分影响的研究进展,以期为氮素对茶树的系统研究提供理论基础,为茶树的高产优质提供科学依据。

Nitrogen （N） is an essential nutrient for tea plants. It is closely associated with the yield and quality of tea. The physiological metabolism and quality-related constituents of a tea plant are significantly affected by the absorption, assimilation, transport, supply, and form of N available to it. In addition, the growth and development of a tea plant also was directly impacted by the interaction of available N and other nutritional elements. Thus, understanding the relationship between N and the physiology of a tea plant is crucial for the science. This article summaries the latest study results and discusses the effects of N on the metabolism and main quality-related compounds in a tea plant so that the fundamental information for the cultivation and breeding of high-yield, high-quality teas is made available.
