| Abstract: | [Objective] The research aimed to study the photosynthetic and physiological index of rice under sprinkler irrigation.[Method] Jie 3 was used as research object in this research and the effects of sprinkler irrigation on photosynthetic rate,transpiration rate,intercellular CO2 concentration,stomatal conductance and water use effciency ofrice were studied.[Result] The photosynthetic rate,transpiration rate,intercellular CO2 concentration,stomatal conductance of rice were at significant level,and the water use efficiency wasn＇t at significant level compared with flood irrigation.[Conclusion] It was superior to sprinkler irrigation,compared with flood irrigation from water-saving point. |
