Review of Water-saving Irrigation Technology in Tea Garden under Drought Stress

Under condition of global climate change and lack of water resource，tea production is obviously restricted by drought stress.Impact of drought stress on tea garden internal mechanism and external performance were discussed，combined with tea area of water-saving irrigation technology application status in our country.A summary of water-saving irrigation technology from engineering measures，agronomic measures，evaporation suppression and catchment measures was regulated.Future development trend of tea plantations of water-saving drought-resistant were addressed，which help to provide technical support and theoretical basis for tea area planning and guide sustainable development of tea industry.
