摘要
茶树在生长过程中常受到高光和高温等不良环境因素的影响,进而影响茶叶的品质与产量。遮阴作为茶园管理中常用的农艺措施,可以通过改善茶园微环境,尤其是光环境,从色泽、香气和滋味等方面提高茶叶的品质,应用前景广泛。文章综述了近年来关于遮阴对茶叶品质和产量的研究进展,从代谢物水平和基因调控水平阐释遮阴对茶叶色泽、香气和滋味的影响,及遮阴环境下茶树的生理响应与产量变化,并探讨了茶树遮阴操作中存在的问题及未来的研究方向,为进一步的研究与应用提供参考。
Tea plants(Camellia sinensis)are often affected by adverse environmental factors such as high light and high temperature during the growth process,which in turn affect the tea quality and yield.Shading is a commonly agronomic measure in the management of tea gardens.It could improve the quality of tea in terms of color,aroma and taste by enhancing the microenvironment of the tea garden,especially the light environment,which has a broad application prospect.This article reviewed the research progress of shading on tea quality and yield in recent years,discussed the effects of shading on tea color,aroma and taste in view of the metabolites and gene regulation,as well as the physiological response and yield changes of tea plants in a shade environment.In addition,this article also discussed the problems and future research directions in tea plant shading operations,and provided a reference for research and application in the future.
