摘要

氮（N）是植物生长发育所必需的主要营养元素,对茶树产量和茶叶品质的形成等具有重要作用。本文介绍了氮素对茶树生长及品质的影响,并从生理过程、分子调控机制以及遗传基础层面综述了茶树氮高效的相关研究进展,归纳梳理了茶树氮高效品种的筛选指标,并对未来研究作了展望。

Abstract

Nitrogen (N) is an essential macronutrient for plant growth and development, and has been the subject of significant research. In recent years, breeding plants with high nitrogen use efficiency (NUE) has become a prominent focus, both theoretically and practically. However, compared with the remarkable research progress achieved in staple food crops such as rice and wheat, little systematic research has been conducted into cash crops. Tea plant (Camellia sinensis) is an important cash crop, with its economic benefits primarily derived from vegetative organs (buds and leaves). Nitrogen plays a crucial role in the growth, morphology, and quality formation of tea leaves. This paper reviewed the effects of nitrogen on tea plant growth and quality, summarized research progress on nitrogen-efficient tea plants from the perspectives of physiological processes, molecular regulatory mechanisms, and genetic foundations, outlined screening criteria for nitrogen-efficient tea cultivars, and provided future research directions.
