Abstract
The experiments were conducted to study leaf photosynthesis and water use efficiency of rice during rice heading stage under drip irrigation with mulch,and the collaborative relationship between photosynthesis and water use efficiency under water stress.The results showed that under drip irrigation with mulch,Pn,Tr decreased while Ci,Gs and WUE were improved as the result of water stress.Water use efficiency was 0.846kg/m3 in the treatment 2(irrigation quota of 13.5mm,irrigation cycle of 2d),and increased by 92.2% compared to that in the traditional flood irrigation,and water-saving effect was remarkable,which was recommended.
