光合作用是绿色植物所具有的生命活动现象。它利用日光能将二氧化碳和水合成糖类,以维持它自身的生命活动,并提供其它生物进行生命活动所需的能量和物质基础。茶树光合作用强弱受不同的品种、年龄、和生育期的影响,而且还受到光、温度、水、肥和二氧化碳浓度等条件的综合影响。因此,在茶叶生产中,应促进、控制、调节各种外界因 Photosynthesis is the phenomenon of life activities of green plants. It uses sunlight to synthesize carbon dioxide and water sugars to maintain its own life activities and to provide the energy and material basis that other living things require. Tea tree photosynthesis is affected by different varieties, ages, and growth periods, but also by light, temperature, water, fertilizer and carbon dioxide concentration and other conditions combined. Therefore, in tea production, various external factors should be promoted, controlled and regulated
