遮阴对茶园生态环境及其茶树光合作用和产量的影响研究

Effects of Shading on Tea Garden Eco-environment,Tea Tree Photosynthesis and Yield

遮阴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等一系列生理与生化过程,最终影响到茶叶产量。从生理生态方面综述了茶园覆盖遮阴对茶园生态环境及茶树光合作用和产量的影响,旨在为遮阴措施在实际应用中提供有益的参考。

Shading could evidently change the micro eco-environment of tea garden,especially affected temperature,humidity of tea tree canopy and physicochemical properties of soil,and then affected tea photosynthesis,finally resulted in the variation of tea production. The effects of shading on tea garden eco-environment,tea tree photosynthesis and production were summarized from physiological and ecological aspects,which aimed to provide reference for the application of shading.
