茶树光合作用在一日中的变化呈双峰曲线形式,无论是茶树生育期或休眠期均有一致的趋向。在保证充足供水及全日控制恒定的环境条件下,茶树的光合作用也呈双峰现象,说明茶树光合作用日变化午间下降的原因是外因和内因综合影响的结果。在年周期中茶树光合作用呈一单峰曲线变化,七月左右全年温度最高季节,茶树光合作用也最强,如以不同年令茶树的单个新梢、整株茶树以及单个枝条为对象,进行测定结果也
The change of photosynthesis in tea plant during the first day showed a bimodal curve, and there was a consistent trend both in the growth period and the dormancy period of tea tree. The photosynthesis of tea plant also showed a bimodal phenomenon under the condition of ensuring adequate water supply and full-day control of constant environment. The reason for the noon decline of photosynthesis of tea plant was the result of the combined effect of external and internal factors. In the annual cycle, the photosynthesis of tea plants showed a single peak curve, the highest temperature in the whole year in July and the strongest photosynthesis in tea plants, such as single shoots, whole tea plants and single shoots of tea plants in different years, We perform measurement result too
