茶树遮荫效应研究进展

Research progress in shading effeciency for tea plants

遮荫可明显改变茶园微域生态环境,尤其对茶树冠层温度、湿度及茶园土壤物理性状的影响较大,进而影响茶树的光合作用、营养物质吸收、代谢及其在茶树体内的重新分配等一系列生理与生化过程,最终影响到茶叶产量与自然品质。

The research progress in Shading efficiency for tea plants was swmmaried. Shading practice in the tea garden evidently changed the microecological environment of tea plants, especially affected the temperature and relative humidity in the crown of tea tree and the physicochemical properties of soil, and then affected the tea photosynthesis, the nutrient uptake, the metabolism and a series of physiological and biochemistry process in the re-distribution of nutrition in tea plants, finally resulted in the variation of its tea production and the formation of the natural quality.
