摘　　要：氮素是对茶叶产量和品质影响最大的营养元素,培育氮素高效利用的茶树品种对于缓解氮肥过度施用导致的茶叶品质降低以及环境问题具有重要意义。本文对近三年来已发表的茶树与氮素营养相关的研究成果进行系统总结,重点关注茶树对不同氮素形态利用以及氮素对茶叶品质影响的基因调控研究,为明晰茶树与氮素营养的内在关系及后续研究开展提供参考。Nitrogen is the nutrient that has the greatest influence on the tea yield and quality.It is necessary to breed tea plant cultivates with high nitrogen use efficiency to alleviate the degradation of tea quality and the deleterious impact on the environment caused by excessive application of nitrogen fertilizers.This paper systematically summarized the published research results on the relationship between tea plants and nitrogen nutrition in the past three years,focusing on the studies on the gene regulation of tea plants on the utilization of different nitrogen forms and levels and their effects on the tea quality.It will be helpful to the deeper understanding the internal relationship between the tea plants and nitrogen nutrition and to make a reference for the further research.
