Abstract：The shortage of water resources and seasonal drought frequently affect the normal growth and development of tea plants, which has become the key factor restricting the development of tea in China. Water-saving irrigation is an important means to relieve the crisis of water resources, and it has a significant advantage in improving crop yield and product quality and reducing irrigation volume and so on. Based on research work of scholars for many years, the effects of water-saving agriculture on growth, yield and quality of tea are reviewed and summarized. It is found that the growth and physiological indexes of tea, such as leaf water potential, leaf biomass, net photosynthetic rate, stomata conductance, transpiration rate, tea polyphenols and free amino acids, caffeine content, would be changed significantly due to the difference of water-saving irrigation technology, irrigation amount and irrigation interval. Through the review of past research in this field, the innovation water-saving irrigation mechanism in tea plantation is put forward, based on the area division of water-saving irrigation in tea plantation, water consumption and growth quality of tea under different water-saving irrigation, effects of water-saving irrigation on microclimate factors and soil factors in tea plantation, and dynamic response model of growth and quality of tea at different growth stages.
