| Abstract: | Effects of different film irrigation modes on rice consumption and water use efficiency was studied at GGSY.The results shows that,water consumption of film flood irrigation is less 7.35% than of flood irrigation,water consumption of film control irrigation is less 3.77% than of control irrigation,water consumption of film intermittent irrigation is less 10.00% than of intermittent irrigation;water use efficiency of film flood irrigation is higher 32.45% than of flood irrigation,water use efficiency of film control irrigation is higher 14.62% than of control irrigation,water use efficiency of film intermittent irrigation is higher 13.59% than of intermittent irrigation. |
